Answers

Answer 1

The surface area of the triangular prism is 72 ft squared.

How to find the surface area of a triangular prism?

The surface area of a triangular prism can be found as follows:

Therefore,

surface area of a triangular prism = bh + l(s₁ + s₂ + s₃)

Hence,

b = 4 ft

h = 3 ft

l = 5 ft

s₁ = 4 ft

s₂ = 3 ft

s₃ = 5 ft

Therefore,

surface area of a triangular prism = 4 × 3 + 5(4 + 3 + 5)

surface area of a triangular prism = 12 + 5(12)

surface area of a triangular prism = 12 + 60

surface area of a triangular prism = 72 ft²

Step-by-step explanation:

from the correct x^(2/5) do we suddenly get to

x^(5/2).

1/x³ = x^(-3) is a correct identity, and using it has no impact on x^(2/5). that should still stay x^(2/5).

the correct step 3 is then

x^(2/5)x^(-3)

step 4 is then

Josh is at a park. He knows that the distance from the picnic table to a tree is 124 feet. Josh also knows the angle formed by a segment from his location to the picnic table and a segment from his position to the tree is 54 degrees and that triangle formed by his position, the picnic table, and the tree is a right triangle, with a right angle at the picnic table. Does josh have enough to find how far he is from the picnic table.

Answers

Answer:

Yes, Josh has enough information to find how far he is from the picnic table.  Josh is 90.1 ft from the picnic table (to the nearest tenth).

Step-by-step explanation:

Yes, Josh has enough information to find how far he is from the picnic table.

From the given information, we can model this as a right triangle where the angle is 54°, the side opposite the angle is the distance between the picnic table and the tree, and the side adjacent the angle is the distance between Josh and the picnic table. (See attached diagram).

To calculate the distance between Josh and the picnic table (labelled "x" on the attached diagram), use the tangent trigonometric ratio.

[tex]\boxed{\begin{minipage}{6 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\end{minipage}}[/tex]

Substitute the values into the tan ratio:

[tex]\implies \tan 54^{\circ}=\dfrac{124}{x}[/tex]

[tex]\implies x=\dfrac{124}{\tan 54^{\circ}}[/tex]

[tex]\implies x=90.09127...[/tex]

[tex]\implies x=90.1\; \sf ft\;(nearest\;tenth)[/tex]

Therefore, Josh is 90.1 ft from the picnic table (to the nearest tenth).

Segments SQ, SU, and QU are tangent to the circle. Segment RQ measures 15 cm, segment ST measures 4 cm, and segment VU measures 25 cm. What is the perimeter of triangle QSU?

Answers

The perimeter of the triangle QSU is 88 cm.

What is Perimeter?

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given a circle.

And there are three tangents drawn intersecting the circle at points R, T and V.

We have the circle theorem that the tangents that meet at the same point are equal in length.

Using the theorem,

SR = ST

RQ = VQ

TU = VU

We have, segment RQ measures 15 cm, segment ST measures 4 cm, and segment VU measures 25 cm.

So, SR = ST = 4 cm

TU = VU = 25 cm

VQ = RQ = 15 cm

Perimeter of ΔQSU = (2 × 4) + (2 × 25) + (2 × 15) = 88 cm

Hence the perimeter is 88 cm.

A man walks for 40 minutes at 60km/h. he then travels for two hrs in a minibus at 80 km/h. Finally he travel by but for an one hour at 60km/h - Find his speed for the whole journey? ​

Answers

Answer: 71km/h

Step-by-step explanation:

He traveled 260km according to what you gave and 100 km using 60 km/h and 160km using 80km/h Also is this man has rocket since he walked 60km/h. His whole journey take 3h40m. Just take 260 divide by 3h40m so you got the final answer about 71km/h

Answer:

70.8 km/h.

Step by step solved:

To find the speed for the whole journey, we need to find the total distance traveled and the total time taken, and then divide the distance by the time.

Let's start by calculating the distance traveled during each leg of the journey:

Distance traveled on foot = speed x time = 60 km/h x 40/60 h = 40 km

Distance traveled in minibus = speed x time = 80 km/h x 2 h = 160 km

Distance traveled on bus = speed x time = 60 km/h x 1 h = 60 km

Now let's add up the distances to find the total distance traveled:

Total distance traveled = 40 km + 160 km + 60 km = 260 km

To find the total time taken, we need to add up the times for each leg of the journey:

Total time taken = 40/60 h + 2 h + 1 h = 3.67 h

Finally, we can divide the total distance by the total time to find the average speed for the whole journey:

Average speed = total distance / total time = 260 km / 3.67 h ≈ 70.8 km/h

Therefore, the man's speed for the whole journey is approximately 70.8 km/h.

Answers

The total possible outcomes is 16, the probability that all children are males is 1/16, the probability of having all one gender is 1/8

What is the possible outcomes

1. The tree diagram for the sex of the children is as follows:

Child 1: M / F

Child 2: M / F

Child 3: M / F

Child 4: M / F

Possible Outcomes: MMMM, MMMF, MMFM, MFMF, FMFM, FMMF, FMFF, FFFF

There are 2 options for each child, so the total number of possible outcomes is 2 x 2 x 2 x 2 = 16.

2. The probability that all children are males is 1/2 x 1/2 x 1/2 x 1/2 = 1/16.

3. The probability of having all one gender of children is the sum of the probability of having all boys and the probability of having all girls. Each of these outcomes has a probability of 1/16, so the total probability is 1/16 + 1/16 = 1/8.

4. The easiest way to solve this problem is to find the probability of having no female children, and then subtract that from 1. The probability of having no female children is (1/2)^4 = 1/16, so the probability of having at least 2 female children is 1 - 1/16 - 1/16 = 7/8.

6. There are 2 options for the first coin flip, 6 options for the second branch, 2 options for the second coin flip, and 3 options for the fourth branch, so the total number of possible outcomes is 2 x 6 x 2 x 3 = 72.

7. The probability of getting only heads on both coin tosses is 1/2 x 1/2 = 1/4. Therefore, the probability of getting only heads on both coin tosses and any result on the dice is 1/4 x 1 = 1/4.

The point (-sqrt2/2, sqrt2/2) is the point at which the terminal ray of angle theta intersects the unit circle. What are the values for cosine and cotangent functions for angle theta

Answers

Hence, the values of cοsine and cotangent functions for angle theta are -√(2)/2 and -1, respectively.

What precisely does a degree angle mean?

Angles between 0 and 90 degrees are cοnsidered acute. Obtuse angles fall within this range and vary frοm 90° to 180°.  A right angle is knοwn as an angle with a 90-degree angle (= 90°).

The pοint (-√(2)/2, √(2)/2) lies on the unit circle in the second quadrant, which means that the cοrresponding angle theta has a reference angle of pi/4.

The cοsine of theta is the x-coordinate of the point on the unit circle corresponding to theta. Since the x-coοrdinate of the given point is -√(2)/2, we have:

cοs(θ) = -√(2)/2

The cοtangent of theta is the ratio of the cosine of theta to the sine of theta. We can find the sine of theta by using the Pythagοrean theorem, since the pοint (-√(2)/2, √(2)/2) lies on the unit circle:

sin(θ) = √(1 - cos²(θ)) = √(1 - (-√(2)/2)²) = √(2)/2

Therefοre, we have:

cot(θ) = cos(θ) / sin(θ) = (-√(2)/2) / (√(2)/2) = -1

Hence, the values of cοsine and cotangent functions for angle theta are -√(2)/2 and -1, respectively.

Determine if the triangles are similar. If similar.state how and complete the similarity statement

Answers

The triangles JTK and KSL are not congruent. So we cannot complete a similarity statement.

what is congruent ?

In geometry, two figures are said to be congruent if they have the same shape and size. In other words, if all corresponding angles are congruent and all corresponding sides are of equal length, then the two figures are congruent.

For example, two triangles are congruent if all three pairs of corresponding angles are congruent and all three pairs of corresponding sides are of equal length. Similarly, two circles are congruent if they have the same radius.

According to the question:
To determine if the triangles JTK and KSL are similar, we need to check if their corresponding angles are congruent and their corresponding sides are in proportion.

First, we can see that angle JTK and angle KSL are congruent because they are both right angles.

Next, we can use the Pythagorean theorem to find the length of side TK:

[tex]TK^2 = JK^2 - JT^2[/tex]

[tex]TK^2 = 14^2 - 2^2[/tex]

[tex]TK^2 = 192[/tex]

TK = sqrt(192)

TK = 8*sqrt(3)

Now, we can compare the ratios of the corresponding sides to see if they are equal:

JT : JK : TK = 2 : 14 : 8*sqrt(3)

KS : KL : SL = 32 : 22.4 : 15.2

We can simplify these ratios by dividing by the greatest common factor, which is 2:

JT : JK : TK = 1 : 7 : 4*sqrt(3)

KS : KL : SL = 8 : 5.6 : 3.8

We can see that these ratios are not equal. Therefore, the triangles JTK and KSL are not similar.

Since the triangles are not similar, we cannot complete a similarity statement.

c. Find the difference between the regular monthly payment and the balloon payment, to the nearest hundred dollars.
d. If the mortgage was not a balloon mortgage, what would be the amount of the monthly payment, rounded to the nearest cent?

Answers

Monthly payment is $973.52, difference is $349,000 and monthly payment for a fully amortizing mortgage would be $3,331.87.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To find the total number of monthly payments, we need to multiply the number of years by 12 (the number of months in a year) and subtract 1 (for the final balloon payment).

So the total number of monthly payments is:

12 x 12 - 1 = 143

b. To find the amount of each monthly payment, we can use the formula

First, we need to convert the APR to a monthly interest rate by dividing by 12:

Monthly Interest Rate = 0.0335 / 12 = 0.002792

Monthly Payment = (350000 x 0.002792) / (1 - (1 + 0.002792)⁻¹⁴³)

= $973.52

The monthly payment is $973.52.

c. The balloon payment is simply the full principal amount of $350,000. The difference between the regular monthly payment and the balloon payment is:

Balloon Payment - Monthly Payment = $350,000 - $973.52 = $349,026.48

The difference is $349,000.

d. To find the monthly payment for a 12-year, fully amortizing mortgage, we can use the same formula as in part b, but with a different Total Number of Payments:

Total Number of Payments = 12 x 12 = 144

Monthly Payment = (350000 x 0.002792) / (1 - (1 + 0.002792)⁻¹⁴⁴) = $3,331.87

The monthly payment for a fully amortizing mortgage would be $3,331.87.

Hence, monthly payment is $973.52, difference is $349,000 and monthly payment for a fully amortizing mortgage would be $3,331.87.

Note that where the conditions above subsist the height determined by the other colleague is not the same so the answer is No. To solve this problem, you need to be conversant with the Pythagorean Theorem, and Angle Bisector Theorems.

What does the Pythagorean Theorem say?

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The formula for the Pythagorean Theorem is:

c² = a² + b²

where "c" represents the length of the hypotenuse and "a" and "b" represent the lengths of the other two sides (the legs) of a right triangle.

With this, we can find the c for the lower Right angle triangle on the left and B for the lower right angle triangle on the right.

Since C² = A² + B²

B = √( A²- C²)

B = √( 9.5²- 6²)

B [tex]\approx[/tex] 7.36546


To determine c on the right angle to the left,

c² = a² + b²

c = √(a² + b²)

c = √(5.5² + 7.2²)

c = 9.060353194

c [tex]\approx[/tex] 9.06

With the postulate of the Angle Bisector Theorem, we can begin to find the height of the two upper right angle triangles.

The Angle Bisector Theorem states that in a triangle, an angle bisector of a vertex of the triangle divides the opposite side into two segments that are proportional to the lengths of the other two sides.

In other words, if a line segment bisects an angle of a triangle and intersects the opposite side or the extension of the opposite side, then the ratio of the lengths of the segments on the opposite side is equal to the ratio of the lengths of the other two sides of the triangle.

As seen from the image, the right angles where each lady is holding is bisected. This means that we have for each Triangle Two angles and one side.

Right Angle on the Left:

90°

45°; and

7.2ft

Given the above, Since the angle opposite the height is 45 degrees, we know that the ratio of the height to the base is 1:1, or h/7.2 = 1/1.

Therefore, the height of the right triangle is:

h = 7.2 × 1

h = 7.2 ft

So the height of the right triangle is 7.2 feet.

Right Angle on the Right :

90°

45°; and

7.36546ft

Given the above, we can use the trigonometric ratios of the angles in the right triangle.

Since the angle opposite the height is 45 degrees, we know that the ratio of the height to the base is 1:1, or h/7.36546 = 1/1.

Therefore, the height of the right triangle is:

h = 7.36546 × 1

h = 7.36546 ft

So the height of the right triangle is 7.36546 feet.


So both heights approximated to the nearest tenth:

7.36546 feet is approximately 7.4 feet7.2 feet remains the same as it is already to the nearest tenth.

Since 7.2 ≠ 7.4, the heights are not equal.

The value of b in the equation is 13/12

How to determine the value of b

From the question, we have the following parameters that can be used in our computation:

x^2/24 - y^2/b^2 = 1

The equation of a hyperbola with center at the origin and semi-axes lengths a and b can be written as:

x^2/a^2 - y^2/b^2 = 1

Comparing this equation with the given equation, we have:

a^2 = 24.

The directrix of the hyperbola is given as

x = 576/26

For a hyperbola with center at the origin, the distance between the center and the directrix is a^2/b.

So, we have:

a^2/b = 576/26

Substituting the value of a^2, we get:

24/b = 576/26

the wind speed y (in miles per hour) of a tropical storm is y = 2x + 66, where x is the same number of hours after the storm enters the gulf of mexico "15 by 15 graph first quadrant" A: Complete the table (show work) B: Graph the equation C: When does the storm become a hurricane

Answers

Answer:

Step-by-step explanatio

A. To complete the table, we need to plug in different values of "x" into the equation y = 2x + 66 and solve for "y". We can choose any values of "x", but it's usually helpful to choose values that are easy to calculate. Here's the table with "x" values ranging from 0 to 7:

x y

0 66

1 68

2 70

3 72

4 74

5 76

6 78

7 80

B. To graph the equation, we can plot the points from the table on a coordinate plane. We can use the x-axis to represent the number of hours after the storm enters the Gulf of Mexico (x), and the y-axis to represent the wind speed in miles per hour (y). The points should fall on a straight line with a slope of 2 and a y-intercept of 66. We can plot the points and draw the line as follows:

C. The wind speed of a tropical storm becomes a hurricane when it reaches or exceeds 74 miles per hour. Looking at the graph, we can see that the wind speed reaches 74 miles per hour when x = 4. Therefore, the storm becomes a hurricane 4 hours after entering the Gulf of Mexico.

one 250 mL serving of tomato juice contains 2/5 the recommended daily intake of vitamin C. how much tomato juice does a person need to consume to get the full recommended daily intake?

Answers

To acquire the complete recommended daily dose of vitamin C, an individual would need to drink 625 mL, or 2.5 cups, of tomato juice.

How is vitamin C calculated?

Calculation. For a common solution Mass Ascorbic acid equals Mole Iodine times Volume of Iodine multiplied by 176.12 to get 91.54 mg per mole of Iodine. At first, 100 mg of ascorbic acid was consumed, making it the complete amount of ascorbic acid.

Let's find out how much vitamin C there is in 250 mL of tomato juice first:

40% vitamin C in 250 mL = 100% vitamin C in x mL

Solving for x, we get:

x = (100% / 40%) * 250 mL

x = 625 mL

A vending machine has 6 different colors of gumballs (red, blue, pink, yellow, green, purple) and an equal chance of dispensing each. Martin buys 6 gumballs. What is the probability of Martin getting exactly 3 pink gumballs?

Answers

The prοbability οf Martin getting exactly 3 pink gumballs οut οf 6 is apprοximately 0.1608 οr 16.08%.

What is prοbability?

Prοbability is a measure οf the likelihοοd οr chance οf an event οccurring. It is expressed as a number between 0 and 1, with 0 indicating an impοssible event and 1 indicating a certain event. The prοbability οf an event can be calculated by dividing the number οf favοrable οutcοmes by the tοtal number οf pοssible οutcοmes.

In the given scenariο, there are 6 different cοlοrs οf gumballs, and each has an equal chance οf being dispensed. Therefοre, the prοbability οf getting any particular cοlοr is 1/6.

Tο find the prοbability οf Martin getting exactly 3 pink gumballs οut οf 6, we need tο use the binοmial prοbability fοrmula:

[tex]\mathrm{P(X=k) = C(n,k) \times p^k \times (1-p)^{(n-k)}}[/tex]

where:

P(X=k) is the prοbability οf getting exactly k successes

n is the tοtal number οf trials (in this case, 6)

k is the number οf successes we want (in this case, 3)

p is the prοbability οf success (in this case, the prοbability οf getting a pink gumball, which is 1/6)

C(n, k) is the number οf cοmbinatiοns οf n things taken k at a time, which can be calculated as n! / (k! × (n-k)!).

Plugging in the values, we get:

P(X=3) = C(6,3) × (1/6)³ × (5/6)³

= (6! / (3! × 3!)) × (1/6)³ × (5/6)³

= 20 × (1/216) ×  (125/216)

= 0.1608

Therefοre, the prοbability οf Martin getting exactly 3 pink gumballs οut οf 6 is apprοximately 0.1608 οr 16.08%.

The mean amount of money spent on lunch per week for a sample of 273
students is $22
. If the margin of error for the population mean with a 98%
confidence interval is 2
, construct a 98%
confidence interval for the mean amount of money spent on lunch per week for all students.

Answers

The true mean amount of money spent on lunch per week for all students falls within the range of $20.12 to $23.88.

Define the term "margin of error"?

Margin of error is a statistical term that refers to the amount of random sampling error that is present in a survey or statistical estimate. In other words, it is the amount of uncertainty or variation that is inherent in any statistical measurement or survey result.

To construct a 98% confidence interval for the mean amount of money spent on lunch per week for all students, we need to use the formula:

Confidence interval = sample mean ± (z-score)(standard error)

Here, the sample mean is $22, the margin of error is 2, and the sample size is 273. To find the z-score for a 98% confidence interval, we can use a standard normal distribution table or calculator. The z-score for a 98% confidence interval is approximately 2.33.

To calculate the standard error, we need to use the formula:

[tex]Standard Error = \frac{standard Deviation}{\sqrt{sample Size} }[/tex]

Since the standard deviation is not given, we can estimate it using the sample standard deviation. Let's assume that the sample standard deviation is $8. The Standard Error calculated as:

[tex]Standard Error = \frac{8}{\sqrt{273} }[/tex]  ≈ 0.48

Substituting the values into the formula for the confidence interval, we get:

Confidence interval = $22 ± 2.33(0.48) ≈ $20.12 to $23.88

Therefore, we can be 98% confident that the true mean amount of money spent on lunch per week for all students falls within the range of $20.12 to $23.88.

Answers

Answer:

Part 1:

Range = 98 - 23 = 75

Part 2:

First, find the sample mean:

Mean = (23 + 53 + 67 + 61 + 66 + 91 + 27 + 85 + 98 + 44 + 73)/11 = 61.9

Then, find the sum of the squared differences between each jersey number and the mean:

(23-61.9)^2 + (53-61.9)^2 + (67-61.9)^2 + (61-61.9)^2 + (66-61.9)^2 + (91-61.9)^2 + (27-61.9)^2 + (85-61.9)^2 + (98-61.9)^2 + (44-61.9)^2 + (73-61.9)^2 = 12388.4

Sample variance = 12388.4/10 = 1238.84

Sample standard deviation = √1238.84 = 35.17

Part 3:

Sample variance = 1238.84

Part 4:

The results tell us that there is a relatively large range in jersey numbers, with a difference of 75 between the highest and lowest numbers. The sample variance and standard deviation also indicate that there is a considerable amount of variability in the data, with jersey numbers varying significantly from the mean. This suggests that there is no pattern or structure to the jersey numbers on the football team, and that they are assigned somewhat randomly.

Consider an investment of $2800 at an APR of 5% compounded monthly. Use the formula that gives the exact doubling time to determine exactly how long it will take for the investment to double.

Express your answer in terms of the number of whole years and remaining months it will take the investment to double. Give your answers as whole numbers.

Answers

It will take {log(1 - r/n)/n} years to exactly double your investment.

What is the formula to calculate compound interest?

The formula for compound interest is -

[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]

Given is that an investment of $2800 made at an APR of 5% compounded monthly.

The formula for compound interest is -

[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]

For A = 2P, we can write -

Substituting 2P = A, we get -

2P = P(1 + r/n)^nt

2 = (1 + r/n)^nt

log 2 = log {(1 + r/n)^nt}

log 2 = (nt) log(1 + r/n)

(log 2)/log(1 + r/n) = nt

{t} = log{2 - 1 - r/n}/n

{t} = log{1 - r/n}/n

Therefore, it will take {log(1 - r/n)/n} years to exactly double your investment.
