If X=11units , y=10units , and Z=13 units , then what is the surface area of the right triangular pyramid shown above ?

Answers

Answer 1

The surface area of the right triangular pyramid is, 269.5 square units

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Dimensions of the right triangular pyramid are,

X = 11 units

Y = 10 units

Z = 13 units

Now, The surface area of the right triangular pyramid is,

Area of Lateral triangle = 1/2 × X × Z

                                    = 1/2 × 11 × 13

                                    = 71.5 unit²

And, Area of Base Triangle = 1/2 ·  base ·  height

                                          = 1/2 ·  X ·  Y

                                          = 1/2 ·  11 units · 10 units

                                          = 55 units²

Now, use the method described above to find the surface area of the pyramid.

Surface Area = 3( Area lateral ) + ( Area base )

                    = 3 ( 71.5 square units ) + ( 55 square units )

                   = 269.5 square units

Thus, The surface area of the right triangular pyramid is, 269.5 square units

The Zyco corporation pays an annual dividend of $2.10 per share. on Tuesdays it closed at $72 per share with a net change of +0.95. The dividend remained at $2.10 for several months. What was the yield on Tuesday? Round to the nearest tenth of a percent. At what price did Zyco close on Monday? nWhat was thenyield at Monday's Close? Round to the nearest tent of a percent?

Answers

In response to the given question, we have that Therefore, on Tuesday, equation the yield was 2.92%, and on Monday, it was 2.96%.

What is equation?

In a math equation, two assertions are connected by the equals sign (=), which denotes equivalence. A mathematical assertion used in algebraic equations establishes the equivalence of two mathematical statements. For instance, in the equation 3x + 5 = 14, the equal sign creates a space between the values 3x + 5 and 14.

Divide the yearly dividend by the share price to determine the yield, then multiply the result by 100 to get the percentage:

Tuesday's yield is calculated as (Annual dividend / Share Price) times 100.

Tuesday's yield is calculated as ($2.10 / $72) times 100, which is 2.92%.

Tuesday's closing price minus Monday's closing price is the difference.

The price on Monday was $72 minus $0.95.

$71.05 was the final price on Monday.

We apply the same procedure as previously to determine the yield as of Monday's close:

Monday's yield is calculated as (annual dividend / share price) x 100.

Yield on Monday is equal to ($2.10 / $71.05) times 100, or 2.96%.

Therefore, on Tuesday, the yield was 2.92%, and on Monday, it was 2.96%.

How to describe and correct Kennedy's error?

No. 2

Kennedy made an error in multiplying (x - 3)(x + 3) because the correct result of this multiplication is x² - 9, not x² - 6x - 9.

This error occurred because Kennedy mistakenly distributed the negative sign when multiplying -3 and +3, resulting in an additional -6x term in the final answer.

The correct way to multiply (x - 3)(x + 3) is to use the FOIL method, which stands for First, Outer, Inner, Last. This gives us:

(x - 3)(x + 3) = x² + 3x - 3x - 9 = x² - 9

No. 3

The product (x + 6)(x - 6) is equivalent to the expression x² - 36, which is called the difference of two squares because it represents the difference between two perfect squares: x² and 6².

Specifically, (x + 6)(x - 6) can be written as x² - 6², and using the identity (a + b)(a - b) = a² - b² we can simplify this to x² - 36.

The percent of the fluid ounces under 60 is option D. Not here

How do you calculate the percent of the fluid ounces?

To calculate the percentage of fluid ounces, you first need to determine the total volume of the container in fluid ounces. Then, you need to determine the volume of the specific substance that you are interested in as a fraction of the total volume. Finally, you can convert this fraction into a percentage by multiplying it by 100.

Here's the formula to calculate the percentage of fluid ounces:

Percentage of fluid ounces = (Volume of substance in fluid ounces ÷ Total volume of container in fluid ounces) x 100%

For example, if you have a 16 fluid ounce container of juice and you want to know what percentage of the container is filled with orange juice, and you measure that there are 4 fluid ounces of orange juice, you can calculate the percentage of orange juice as follows:

Percentage of orange juice = (4 fluid ounces ÷ 16 fluid ounces) x 100% = 25%

Therefore, the orange juice fills 25% of the 16 fluid ounce container. It could then be concluded that the percent of the fluid ounces is not here.

The volume of the right cone below is 1152π/3 cubic units then the value of x is 24.

What is the volume of a right circular cone?

The volume of a right circular cone is given by the formula:

V = (1/3)πr²h

where π is pi (approximately equal to 3.14), r is the radius of the circular base, and h is the height of the cone.

In this problem, we are given that the volume of the cone is 1152π/3 cubic units and that the value of x is related to the radius and height of the cone.

Let's first write the formula for the volume of the cone in terms of x:

V = (1/3)π(x/3)²(x/3)

Simplifying this expression, we get:

V = (1/27)πx²

We are given that V = 1152π/3, so we can substitute this into the formula above and solve for x:

1152π/3 = (1/27)πx³

Multiplying both sides by 27/π, we get:

x³ = 1152*27/3

x³ = 27648

Taking the cube root of both sides, we get:

x = 24

Two Italians and three Englishmen are looking for accommodation in the hotel as loyal guests. In the hotel for accommodation their loyal guests are guarded by 8 rooms, of which 3 rooms have walls painted blue, in 3 rooms in green color, and in the remaining 2 rooms in yellow color. Italians want to be either in blue or in the yellow room, and the English in either the green or the yellow room. In how many ways did the two Italians and three Englishmen can be assigned rooms so that each of them is alone in one room?​

Answers

Answer:

To solve this problem, we can use the principle of inclusion-exclusion. We first count the total number of ways to assign rooms to the Italians and Englishmen without any restrictions. Then, we subtract the number of ways that violate the Italian's restriction, and the number of ways that violate the Englishmen's restriction. Finally, we add back the number of ways that violate both restrictions.

Step 1: Total number of ways to assign rooms

There are 8 rooms, so there are 8 choices for the first person, 7 choices for the second person, and so on. Therefore, there are 8 x 7 x 6 x 5 x 4 = 6,720 total ways to assign rooms to the Italians and Englishmen without any restrictions.

Step 2: Number of ways that violate the Italian's restriction

There are 3 blue rooms and 2 yellow rooms, so there are 3 x 2 = 6 ways to assign rooms to the Italians that violate their restriction. For each of these ways, there are 6 x 5 x 4 = 120 ways to assign rooms to the Englishmen. Therefore, there are 6 x 120 = 720 ways that violate the Italian's restriction.

Step 3: Number of ways that violate the Englishmen's restriction

There are 3 green rooms and 2 yellow rooms, so there are 3 x 2 = 6 ways to assign rooms to the Englishmen that violate their restriction. For each of these ways, there are 5 x 4 x 3 x 2 = 120 ways to assign rooms to the Italians. Therefore, there are 6 x 120 = 720 ways that violate the Englishmen's restriction.

Step 4: Number of ways that violate both restrictions

If the Italians are in blue rooms and the Englishmen are in yellow rooms, there is only 1 choice for this assignment. If the Italians are in yellow rooms and the Englishmen are in green rooms, there are also only 1 choice for this assignment. Therefore, there are 2 ways that violate both restrictions.

Step 5: Calculate the final answer

Using the principle of inclusion-exclusion, we can calculate the number of ways that satisfy all the restrictions as follows:

Total number of ways - Number of ways that violate the Italian's restriction - Number of ways that violate the Englishmen's restriction + Number of ways that violate both restrictions

6,720 - 720 - 720 + 2 = 5,282

Therefore, there are 5,282 ways to assign rooms to the two Italians and three Englishmen so that each of them is alone in one room, while satisfying their loyal guest preferences.

7(x+8)=49

i know the answer but tell me how did you solve it only with numbers and mathematical letters nothing else

Answers

Answer:
- Divide both sides by 7
x + 8 = 49/7
- Simplify 49/7 to 7
x + 8 = 7
- Subtract 8 from both sides
x = 7 - 8
- Simplify 7 - 8 to -1
x = -1
I would distribute the 7 to x and 8 by multiplying them by 7 which would give you 7x+56=49. Then I would subtract 56 from 56 and 49 which would give you -7. Now we should have 7x=-7. Now we divide 7x by 7 and -7 which would equal -1.

find the range for the measure of the third side of a triangle given the measures of two sides, 7km and 29km

Answers

By answering the above question, we may state that Thus, the third side function might be anywhere between 22 and 36 kilometer's long.

what is function?

Mathematicians research numbers, their variants, equations, forms, and related structures, as well as possible locations for these things. The relationship between a group of inputs, each of which has a corresponding output, is referred to as a function. Every input contributes to a single, distinct output in a connection between inputs and outputs known as a function. A domain, codomain, or scope is assigned to each function. Often, functions are denoted with the letter f. (x). The key is an x. There are four main categories of accessible functions: on functions, one-to-one capabilities, so many capabilities, in capabilities, and on functions.

The triangle inequality theorem states that the third side of a triangle's length must be bigger than the difference between the other two sides and less than the total of the other two sides.

Hence, the third side's range of potential lengths for a triangle with sides of 7 km and 29 km is:

The third side's length is less than 29 km plus 7 km, which equals 36 km.

The third side is longer than 29 km minus 7 km, which equals 22 km.

Thus, the third side might be anywhere between 22 and 36 kilometer's long.

Swimming Pool On a certain hot summer's day, 631 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $1013.00. How many children and how many adults swam at the public pool that day?​

Answers

Answer: Let's use the variables c and a to represent the number of children and adults who used the pool, respectively.

We know that the total number of people who used the pool is 631, so we can write:

c + a = 631 (equation 1)

We also know that the total receipts for admission were $1013.00. The cost for children is $1.25 and the cost for adults is $2.00, so we can write:

1.25c + 2a = 1013 (equation 2)

Now we have two equations with two unknowns. We can solve for c and a by using elimination or substitution.

Let's use elimination. Multiply equation 1 by 1.25 to get:

1.25c + 1.25a = 788.75 (equation 3)

Subtract equation 3 from equation 2 to eliminate c:

0.75a = 224.25

a = 299

Now we can use equation 1 to solve for c:

c + 299 = 631

c = 332

Therefore, there were 332 children and 299 adults who used the pool that day.

Answers

The profit for selling 300 vetkoek every week at a cost of 3.80 per vetkoek and selling them for 10 each is 1860.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To calculate the profit for selling 300 vetkoek every week, we need to first calculate the total revenue generated and the total cost of producing the vetkoek.

Total revenue = Price per vetkoek x Number of vetkoek sold

Total revenue = 10 x 300 = 3000

Total cost = Cost per vetkoek x Number of vetkoek sold

Total cost = 3.80 x 300 = 1140

Profit = Total revenue - Total cost

Profit = 3000 - 1140 = 1860

D. Categories are descriptions of data, such as which grades students received on a test or the heights of trees in a forest.

They can describe qualities or represent counts or measurements.

The frequency of a category is the number of data values in the category.

A frequency table is a table that displays the categories or groups of a set of data along with their corresponding frequencies.

The categories are typically represented in the left column, and the frequencies are listed in the right column.

The categories represent the possible values or ranges of values that the data can take.

For example, in a frequency table of student grades on a test, the categories might be "A," "B," "C," "D," and "F."

The frequency of a category is the number of times that the data falls within that category.

For example, if there are 20 students in a class and 5 of them received an "A" on a test, then the frequency of the "A" category would be 5.

Relative frequency is the proportion or percentage of observations in a category relative to the total number of observations.

It is calculated by dividing the frequency of a category by the total number of observations.

For example, if there are 20 students in a class and 5 of them received an "A" on a test, then the relative frequency of the "A" category would be 5/20 = 0.25 or 25%.

Cumulative frequency is the running total of frequencies for a set of data.

For example, if the frequency of the "A" category is 5 and the frequency of the "B" category is 10, then the cumulative frequency of the "B" category would be 5 + 10 = 15.

It represents the total number of observations that fall within a category and all previous categories.

Use complete sentences. (4 points) Part D: How many points are awarded for 20 minutes of play? (2 points)

Answers

Answer:

Step-by-step explanation:

Therefore, 12 minutes of play awards 4.5 points.

The constant of proportionality is 1/4, which means that for every minute of play, 1/4 point is awarded and 5 points are awarded for 20 minutes of play.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that for every 4 minutes of play, 1/2 point is awarded.

For every 12 minutes of play, 1 1/2 points are awarded.

We can set up a proportion to find the constant of proportionality:

(1/2 point) / (4 minutes) = (3/2 points) / (12 minutes)

Simplifying the left side, we get:

1/8 = (3/2 points) / (12 minutes)

Multiplying both sides by 12, we get:

1.5 = (3/2)P

P = (1.5) x (2/3) = 1

Therefore, the constant of proportionality is 1/4, which means that for every minute of play, 1/4 point is awarded.

By constant of proportionality, the equation that represents the relationship between the number of points awarded and the amount of time played:

P = (1/4)t

To find the number of points awarded for 20 minutes of play, we can use the equation P = (1/4)t:

P = (1/4)(20)

= 5

Hence, the constant of proportionality is 1/4, which means that for every minute of play, 1/4 point is awarded and 5 points are awarded for 20 minutes of play.

Every morning before your first class, you line up at Tim Horton's on the BCIT campus.
You notice that it takes between 19 to 35 minutes to get through the lineup, give your
order to the cashier, and receive your coffee, donut, and wrap. The time to get your
order follows a uniform distribution.
(a) What is the probability that it will take at least 23minutes to get your order??
(enter a number between 0 and 1 in 4 decimal places)
(b) You arrive at Tim Horton's at 7:30am. What is the probability that you receive your
order before your friends show up at 8:00am at Tim's?
(enter a number between 0 and 1 in 4 decimal places)
(c) 10% of the time it takes you longer than how many minutes to get your
order?
(answer in 2 decimal places)
min

Answers

Answer: (a) Since the time to get the order follows a uniform distribution between 19 to 35 minutes, the probability of getting the order in any interval of time within this range is proportional to the length of that interval. Therefore, the probability of taking at least 23 minutes to get the order is:

P(X ≥ 23) = (35 - 23) / (35 - 19) = 0.4

Rounding to 4 decimal places, the probability is:

P(X ≥ 23) ≈ 0.4000

(b) If you arrive at Tim Horton's at 7:30am and your friends show up at 8:00am, you have 30 minutes to receive your order. Since the time to get the order follows a uniform distribution, the probability of receiving the order before your friends show up is the probability of getting the order in 30 minutes or less, which is:

P(X ≤ 30) = (30 - 19) / (35 - 19) = 0.5789

Rounding to 4 decimal places, the probability is:

P(X ≤ 30) ≈ 0.5789

(c) Let's call the time in minutes to get the order that is longer than 10% of the time as t. Since the distribution is uniform, we know that the probability of taking longer than t minutes is 0.1. Therefore, we can write:

(35 - t) / (35 - 19) = 0.1

Solving for t, we get:

t = 19 + 0.9(35 - 19) = 32.4

Rounding to 2 decimal places, we get:

t ≈ 32.40 minutes

Therefore, 10% of the time it takes longer than 32.40 minutes to get the order.

For each table, state if the model is linear or exponential and write an equation

Answers

Answer:

4. y = 192 * 4^x

5. y=8*2^(-x)

6. y = -2.5x - 37

Step-by-step explanation:

4.

From the given data, we can see that as x increases by 1, y increases by a factor of 4.

Using the second and third data points, we can find a and b as:

When x = -2, y = 12, so we have:

12 = ab^(-2)

When x = -1, y = 48, so we have:

48 = ab^(-1)

Dividing the second equation by the first, we get:

4 = b^1

So b = 4, and substituting this into the first equation, we get:

12 = a(4)^(-2)

Simplifying, we get:

a = 192

So the equation for this exponential relationship is:

y = 192(4)^x

Simplifying further:

y = 192 * 4^x

5.

From the given data, we can see that as x increases by 1, y decreases by a factor of 2.

Using the second and third data points, we can find a and b as:

When x = -2, y = 32, so we have:

32 = ab^(-2)

When x = -1, y = 16, so we have:

16 = ab^(-1)

Dividing the second equation by the first, we get:

16/32=b^(-2+1)

1/2=b^(-1)

b=2

So b = 2, and substituting this into the first equation, we get:

32 = a*2^(-2)

32= 4a

a=32/4

a=8

So the equation for this exponential relationship is:

y = 8(2)^(-x)

Simplifying further:

y=8*2^(-x)

6.

The data suggests that as x increases by 1, y decreases by a constant amount. This suggests that the relationship between x and y is linear.

To find the equation for this relationship, we can use the slope-intercept form of a linear equation:

y = mx + b

where m is the slope and b is the y-intercept.

To find the values of m and b, we can use any two data points. Let's use the first and last data points:

When x = -3, y = -29.5, so we have:

-29.5 = m(-3) + b

When x = 3, y = -44.5, so we have:

-44.5 = m(3) + b

We can now solve for m and b. Subtracting the first equation from the second equation, we get:

-15 = 6m

So, m = -2.5.

Substituting this value into the first equation, we get:

-29.5 = (-2.5)(-3) + b

-29.5=7.5+b

b=-29.5-7.5

So, b =-37

Therefore, the equation for this linear relationship is:

y = -2.5x - 37

[tex]\textsf{6)} \quad \textsf{Linear:} \quad y=-2.5x-37[/tex]

Step-by-step explanation:

Linear function

When the x-values increase by a constant amount, the y-values have a constant difference.

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Linear Function}\\\\$f(x)=ax+b$\\\\where:\\ \phantom{ww}$\bullet$ $a$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Exponential function

When the x-values increase by a constant amount, the y-values have a constant ratio.

[tex]\boxed{\begin{minipage}{9 cm}\underline{Exponential Function}\\\\$f(x)=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

Question 4

From inspection of the given table, as the x-values increase by one, the y-values are 4 times the previous y-value. Therefore, they have a constant ratio of 4. This means that the equation is exponential.

The initial value "a" is the y-intercept, so a = 192.

The y-values have a growth factor of 4, so b = 4.

Substitute these values into the formula to create an equation for the table of values:

[tex]\boxed{y=192 \cdot 4^x}[/tex]

Question 5

From inspection of the given table, as the x-values increase by one, the y-values are half the previous y-value. Therefore, they have a constant ratio of 1/2. This means that the equation is exponential.

The initial value "a" is the y-intercept, so a = 8.

The y-values have a growth factor of 1/2, so b = 1/2.

Substitute these values into the formula to create an equation for the table of values:

[tex]\boxed{y=8\cdot \left(\dfrac{1}{2}\right)^x}[/tex]

Question 6

From inspection of the given table, as the x-values increase by one, the y-values decrease by 2.5. Therefore, they have a constant difference of -2.5. This means that the equation is linear.

The slope "a" is the change in y-values divided by the change in x-values. As the y-values decrease by 2.5 for ever increase in one in the x-values, a = -2.5.

The y-intercept is the y-value when x = 0, so b = -37.

Substitute these values into the formula to create an equation for the table of values:

[tex]\boxed{y=-2.5x-37}[/tex]

22 miles in 20 minutes is greater than less than or equal to 38 miles in 30 minutes

Answers

Answer:

True

Step-by-step explanation:

To compare the two speeds, we can calculate the speed of each in miles per hour (mph) and then compare them.

22 miles in 20 minutes = (22/20) miles per minute = 1.1 miles per minute

To convert to mph, we can multiply by 60 to get:

1.1 x 60 = 66 mph

38 miles in 30 minutes = (38/30) miles per minute = 1.27 miles per minute

To convert to mph, we can multiply by 60 to get:

1.27 x 60 = 76.2 mph

Therefore, 38 miles in 30 minutes is faster than 22 miles in 20 minutes, as 76.2 mph is greater than 66 mph.

In other words, the statement "22 miles in 20 minutes is less than 38 miles in 30 minutes" is true.

The sum of an odd integer and 4 times the next consecutive integer is 63
Find the value of the greater integer

Answers

Answer:

the greater integer is "y", which is 13.

Step-by-step explanation:

Let's call the odd integer "x", and the next consecutive integer "y". Since "y" is the next consecutive integer after "x", we know that:

y = x + 2

We are told that the sum of "x" and 4 times "y" is 63. We can set up an equation to represent this:

x + 4y = 63

Now we can substitute the expression for "y" in terms of "x" into this equation:

x + 4(x + 2) = 63

Simplifying this equation, we get:

x + 4x + 8 = 63

5x + 8 = 63

Subtracting 8 from both sides, we get:

5x = 55

Dividing both sides by 5, we get:

x = 11

So the odd integer is 11. We can use the expression for "y" in terms of "x" to find the next consecutive integer:

y = x + 2 = 11 + 2 = 13

Therefore, the greater integer is "y", which is 13.

Answer:

13

Step-by-step explanation:

there is an interval of 2 between consecutive odd numbers

let n and n + 2 be the 2 consecutive integers , then

n + 4(n + 2) = 63 , that is

n + 4n + 8 = 63

5n + 8 = 63 ( subtract 8 from both sides )

5n = 55 ( divide both sides by 5 )

n = 11

then larger integer is n + 2 = 11 + 2 = 13

what's the end behavior of: y= 2 + log2(x - 1)

Answers

We can infer that the function y = 2 + log2(x - 1) has the following final behaviour:

Y gets closer to infinity as x gets closer to positive infinity.Y moves closer to negative infinity as x moves in the proper direction towards 1.what is a function?

A function is a relationship between a number of inputs and outputs. Simply described, a function is an association between inputs in which each input is coupled to exactly one output. There is a range, codomain, and domain for every function. A function is typically referred to as f(x), where x is the input. Y = f is a common way to represent a function (x).

A function in mathematics is a certain configuration of the inputs (also known as the domain) and their outputs (also known as the codomain), where each input has precisely one output and the output can be connected to its input.

from the question;

We may look at what happens to the function as x gets closer to positive and negative infinity to figure out the final behaviour of the function

y = 2 + log2(x - 1).

The formulas (x - 1) and log2(x - 1) also approach infinity as x gets closer to positive infinity. As a result, y increases as x moves closer to positive infinity. The following can be written:

lim x→∞ 2 + log2(x - 1) = ∞

Expression (x - 1) moves closer to zero and log2(x - 1) moves closer to negative infinity as x moves towards 1 from the right. So, as x moves closer to 1 from the right, y moves closer to negative infinity. The following can be written:

lim x→1+ 2 + log2(x - 1) = -∞

This leads us to the following conclusion about the final behaviour of the function y = 2 + log2(x - 1):

Y gets closer to infinity as x gets closer to positive infinity.Y moves closer to negative infinity as x moves in the proper direction towards 1.

Find measurement of side A'C' and B'C'?

Answers

Answer:

AC = 14.9

BC = 10.5

Step-by-step explanation:

The triangle is a isosceles right triangle with ∠B = 90o, ∠A = ∠C = 45o.

Therefore AB = BC = 10.5

Pythagorean theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse, which is AC.

AC^2 = AB^2 + BC^2

AC^2 = 2AB^2

AC^2 = 2(10.5)^2

AC^2 = 220.5

AC = √220.5 = 14.85 or 14.9

There are some drug and alcohol abuse problems among the employees. Women have traditionally been employed only in the lower clerical ranks. The 72 2 of 2 jail has a "macho" culture, which the county wants to see being changed to a more caretaking culture with emphasis on rehabilitation and training for inmates and a special needs program for juvenile offenders. -Counseling, library, and chaplain services are not available to staff and inmates. The organization could outsource (privatize) gardening, laundry, and janitorial services more cheaply than what is provided in-house through work. There will be a state review of how the juvenile offenders are managed in Cedarville. If there are continuing problems in this area, the state is considering a voucher program to enable juvenile offenders to be moved to the Catholic Juvenile Male Institutional Facility, a non-profit organization outside Cedarville, or to the Raleigh Institution for Young Men, a private detention center in Cedarville. If the review is bad, the Cedarville jail stands to lose a substantial portion of its budget.
