The diameter of a spherical ballon shrinks to one-half of it’s original size. Describe how the surface area and volume of the balloon change.

Answers

Answer 1

Answer:

when the diameter of a spherical balloon shrinks to one-half of its original size, the surface area of the balloon will decrease to one-fourth of its original size, while the volume will decrease to one-eighth of its original size.

Step-by-step explanation:

When the diameter of a spherical balloon shrinks to one-half of its original size, it means the new diameter is half of the original diameter.

Let's assume the original diameter of the balloon was "d," then the new diameter will be "d/2."

Surface Area:

The surface area of a sphere is given by the formula 4πr², where "r" is the radius of the sphere. Since the diameter of the sphere is halved, the radius will also be halved. Therefore, the new surface area (SA') of the balloon will be:

SA' = 4π (d/4)² = πd²/4

Thus, the new surface area of the balloon will be one-fourth (1/4) of the original surface area.

Volume:

The volume of a sphere is given by the formula (4/3)πr³. Again, since the diameter of the sphere is halved, the radius will also be halved. Therefore, the new volume (V') of the balloon will be:

V' = (4/3)π (d/4)³ = πd³/24

Thus, the new volume of the balloon will be one-eighth (1/8) of the original volume.

Desmond kept track of his results for all 72 rolls. The table at right shows some of his results. Based on his partial results, how many times did he roll a 5 or a 6?

Answers

The number of times of rolling a 5 or a 6 in the fair die is 24

What is a reasonable prediction for the number of times of rolling a 5 or a 6?

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

Fair 6-sided die = 72 times

In a 6-sided die, we have

P(5 or 6) = 2/6

When evaluated, we have

P(5 or 6) = 1/3

So, when the die is rolled 72 times, we have

Expected value = 1/3 * 72

Evaluate

Expected value = 24

Hence, the number of times is 24

3. Suppose a simple random sample of 150 college students is drawn. Among sampled students, the average IQ score is 115 with a standard deviation of 10. What is the 95% confidence interval for the ents^ prime IQ score?

Answers

Answer: is approximately between 113.39 and 116.61
To calculate the 95% confidence interval for the students' average IQ score, we'll use the given information: sample size (n=150), sample mean (X=115), and sample standard deviation (s=10). We'll use the t-distribution since the population standard deviation is unknown.

First, we need to find the t-value for a 95% confidence interval with n-1 (149) degrees of freedom. Using a t-table or calculator, we find the t-value to be approximately 1.976.

Next, we'll calculate the standard error (SE) using the formula: SE = s/√n. In this case, SE = 10/√150 ≈ 0.816.

Now, we can find the margin of error (ME) using the formula: ME = t-value × SE. For this problem, ME = 1.976 × 0.816 ≈ 1.61.

Finally, to calculate the 95% confidence interval, we'll use the formula: X ± ME. Thus, the 95% confidence interval is 115 ± 1.61, which is approximately (113.39, 116.61).

So, the 95% confidence interval for the students' average IQ score is approximately between 113.39 and 116.61.

D) the value of the 6 in 26. 495 is 10 times the value of the 6 in 17. 64

Answers

The correct statement that compares the value of the 6 in 26.495 and 17.64 is the value of the 6 in 26.495 is 10 times the value of the 6 in 17.64. Therefore, the correct option is D.

This is because the value of a digit is determined by its place in the number. In 26.495, the 6 is in the tenths place, which means it represents 6/10 or 0.6. In 17.64, the 6 is in the hundredths place, which means it represents 6/100 or 0.06. Therefore, the value of the 6 in 26.495 is 0.6 and the value of the 6 in 17.64 is 0.06.

To compare these values, we can divide the value of the 6 in 26.495 by the value of the 6 in 17.64. This gives us 0.6/0.06 = 10. Therefore, the value of the 6 in 26.495 is 10 times greater than the value of the 6 in 17.64 which corresponds to option D.

Make d the subject of the formula t=4b²/21(d-3b/5)​

Answers

The formula for d is d = (t * 21/4b² + 3b)/5

To make d the subject of the formula t=4b²/21(d-3b/5), we need to isolate d on one side of the equation and simplify.

First, let's simplify the right side of the equation by multiplying the fraction by the LCD of 5:

t = 4b²/21(d-3b/5)

t = (4b²/21d) * 5d - 3b

Now, we can isolate d by dividing both sides of the equation by the coefficient of d on the right side:

t/(4b²/21) = 5d - 3b

Simplifying the left side, we get:

t * 21/4b² = 5d - 3b

Adding 3b to both sides of the equation, we get:

t * 21/4b² + 3b = 5d

Finally, we can divide both sides by 5 to isolate d:

d = (t * 21/4b² + 3b)/5

Therefore, the formula for d is:

d = (t * 21/4b² + 3b)/5

In words, to find the value of d, we need to multiply the value of t by 21/4b², add 3b to the result, and divide the sum by 5.

UNO is card game: standard UNO deck consist of 108 cards four each of Wild and Wild Draw Four; and 25 each of four different colors (red yellow; green, blue): Each color consists of number cards (one zero, two each of through 9) and two cards each of Skip, Draw Two and Reverse_ These last three types are known as action cards. To begin the game (using well shufiled deck) seven card hand is dealt to each player (without replacement) . Consider an outcome space without order Without worrying about how many players are there, find the probability of a player starting of with: a whole hand of action cards_ b a hand of cards with out any Wild (Wild or Wild Draw Four) cards. Explain your answer by giving clear description of an equally-likely outcomes model on which it is based_ In other words, tell me what 0 and events you are using; how many elements they have?

Answers

Therefore, a person starts with a hand of cards without any Wild (Wild or Wild draw four) is 0.5741

and a number of outcomes of event 'B' is 16007560800.

How to solve

total number of cards = N = 108

wild cards = 4

wild draw four = 4

we have 4 different colors and each color has 25 cards with break down as

zero numbered card = 1

numbered from 1 to 9 = 2 each (total 18)

skip = 2

draw two = 2

reverse = 2

skip, draw two and reverse are action cards

therefore, in a deck of UNO we have 3*2*4 = 24 action cards

a seven-card hand is dealt to each player from a well shuffled pack of card.

therefore, as each card is equally likely, we have total possible outcomes as 108C7

Ω is a event of every possible outcome and it has 108C7 = 27883218168 elements

an equally likely model is a model where equal weights are attached to every outcome and thus the probability of each outcomes become equal.

1) let 'A' be the event a whole hand is of action cards.

we have a total of 24 action cards in a UNO deck of 108 cards.and we have to draw a hand of 7 cards

total number of outcomes for event 'A' is 24C7

therefore, the probability that a player starting with a whole hand of action cards is

= [tex]24C7\n108C7\n[/tex]

= 0.0000124

therefore, a person starts with a whole hand of action card is 0.0000124

and the number of outcomes of event 'A' is 346104

2) let 'B' be the event that a hand of card is without any wild card

therefore we have a total of 100 cards that do not have any wild ( wild or wild draw four) cards

therefore a hand of 7 out of 100 cards for event 'B' can be drawn in 100C7 total ways

therefore, the probability that a player starts with a hand of cards without any Wild (Wild or Wild draw four) cards is

= [tex]100C7\n108C7\n[/tex]

= 0.5741

therefore, a person starts with a hand of cards without any Wild (Wild or Wild draw four) is 0.5741

(d) Probability of at least one major earthquake in the next 49 years is 0.9884, and (e) the probability of no major earthquakes in the next 49 years is 0.0116.

We will use the Poisson distribution to compute the probabilities. First, we need to find the value of λ (average number of earthquakes in a given time period).

(d) Compute the probability of at least one major earthquake in the next 49 years:

1. Calculate λ for 49 years:

(2.0 earthquakes / 22 years) * 49 years = 4.45 (rounded to the nearest hundredth)

2. Compute the probability of no major earthquakes (P(0)) in the next 49 years using Poisson distribution formula:

P(0) = (e^(-λ) * (λ^0)) / 0! = (e^(-4.45) * (4.45^0)) / 1 = 0.0116 (rounded to 4 decimal places)

3. Compute the probability of at least one major earthquake:

P(at least 1) = 1 - P(0) = 1 - 0.0116 = 0.9884

So, the probability of at least one major earthquake in the next 49 years is 0.9884 (rounded to 4 decimal places).

Hi! I'd be happy to help you with your question about transformations and congruence. When Triangle ABC is reflected over the x-axis, the algebraic rule applied to the figure is:

Your answer: (x, y) → (x, -y)

This rule states that the x-coordinate remains the same, while the y-coordinate is multiplied by -1, resulting in a reflection over the x-axis. This transformation preserves congruence, as the size and shape of Triangle ABC remain the same, only its position changes.

The algebraic rule applied to the figure when Triangle ABC is reflected over the x-axis is (x,y) → (x,-y), where x represents the x-coordinate and y represents the y-coordinate. This is because reflecting a figure over the x-axis involves keeping the x-coordinate the same while changing the sign of the y-coordinate.

We have an equation, 4x + 8y = 20 --(1) which is linear equation with two variables. We have to determine the the x- and y-intercepts of the graph of equation (1). The graph of line (1) is present in above figure. Slope intercept form of equation (1) is written as [tex]y = - \frac{1}{2}x + \frac{5}{2}[/tex],

The x-intercept is point where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. As we know, two points determine any line, we can graph lines using the x- and y-intercepts. To determine the x-intercept, we substitute y=0 and solve for x. So, when y = 0 then 4x + 0 = 20

=> x = 5

similarly to determine the y-intercept, set x=0 and solve for y. When x = 0

=> 8y = 20

=> y = 5/2.

Hence, required value are (5,0) and (0,5/2).

Given that segment KL is parallel to segment MN and that segment KN bisects segment ML, prove that segment KO is congruent to segment NO

Answers

If that segment KL is parallel to segment MN and that segment KN bisects segment ML, then segment KO is congruent to segment NO.

To prove that segment KO is congruent to segment NO, we need to show that triangle KNO is an isosceles triangle, with KO ≅ NO.

From the given information, we know that KL is parallel to MN, which means that angle KLN is congruent to angle MNL (corresponding angles). Also, KN bisects segment ML, which means that angle KNO is congruent to angle NMO (angle bisector theorem).

Therefore, we have:

angle KNO = angle NMO

angle KLN = angle MNL

Adding these two equations gives us:

angle KNO + angle KLN = angle NMO + angle MNL

But angle KLN + angle NMO + angle MNL = 180 degrees (as they form a straight line). So we can substitute this into the equation:

angle KNO + 180 degrees = 180 degrees

Simplifying, we get:

angle KNO = 0 degrees

This means that KO and NO are on the same line, so they must be congruent. Therefore, we have proven that segment KO is congruent to segment NO.

Answers

If it has a 15% yearly interest rate and the interest is compounded monthly and the card has $0 minimum payments for the first four years it is active. Therefore, Emma will owe approximately $529.27 in four years.

To calculate how much Emma will owe in four years, we need to use the compound interest formula: A = P (1 + r/n)^(n*t)

where:

A = the amount of money at the end of the investment period

P = the principal amount (the initial amount of money borrowed)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period in years

In this case, the principal amount is $300, the annual interest rate is 15%, and the interest is compounded monthly (so n = 12). The time period is four years.

Plugging in the values, we get:

A = 300(1 + 0.15/12)^(12*4)

A ≈ $529.27

Therefore, Emma will owe approximately $529.27 in four years if she doesn't pay off her credit card until after college.

The surface area of revolution of C about the x-axis is π/27 (81^(3/2) - 1) or approximately 478.48 units².

How to the surface area of revolution of a curve?

To find the surface area of revolution of C about the x-axis, we can use the formula:

Surface area = ∫2πy ds

where y is the function that defines the curve C, and ds is an element of arc length along the curve.

We can express ds in terms of dx as follows:

ds = √(1 + (dy/dx)²) dx

where dy/dx is the derivative of y with respect to x.

For the curve C, we have:

y = 3x³

dy/dx = 9x²

Substituting these into the expression for ds, we get:

ds = √(1 + (9x²)²) dx

= √(1 + 81x⁴) dx

Substituting y and ds into the formula for surface area, we get:

Surface area = ∫₂πy √(1 + (dy/dx)²) dx

= ∫₀³ 2π(3x³) √(1 + 81x⁴) dx

This integral can be evaluated using substitution:

Let u = 1 + 81x⁴

Then du/dx = 324x³

And dx = du/324x³

Substituting these into the integral, we get:

Surface area = ∫₁₀³ 2π(3x³) √(1 + 81x⁴) dx

= 2π/108 ∫₁₀³ (3x³) √u du

= π/54 ∫₁₀³ u^(1/2) du

= π/54 (2/3) u^(3/2) | from 1 to 81

= π/81 (2/3)(81^(3/2) - 1)

= π/27 (81^(3/2) - 1)

Therefore, To find the surface area of revolution of C about the x-axis, we can use the formula:

Surface area = ∫2πy ds

Substituting these into the integral, we get:

Surface area = ∫₁₀³ 2π(3x³) √(1 + 81x⁴) dx

To calculate the assets taxes, we need to multiply the appraised cost by means of the tax rate, which is 1.22% or 0.0122 as a decimal:

property taxes = $265,000 x zero.0122 = $3,243.50

Therefore, you have to pay $3,243.50 in property taxes.

It's far essential to factor in property taxes whilst thinking about the general price of purchasing a home and to recognize the method for applying for exemptions or appealing the appraised cost if necessary.

A manufacturer makes aluminum cups with a volume of 10 cubic centimetres cach, in the form of right circular cylinders open at the top. Find the dimensions that would require the least amount of material.

Answers

The dimensions that require the least amount of material are r = (10/π)^(1/3) cm for the radius and h = (10/π)^(1/3) cm for the height.

To minimize the amount of material used for making aluminum cups with a volume of 10 cubic centimeters, you will need to optimize the dimensions of the right circular cylinders.

Given the volume (V) is 10 cm³, the formula for the volume of a right circular cylinder is V = πr²h, where r is the radius and h is the height.

10 = πr²h

To minimize the material used, we want to minimize the surface area (SA) of the open cylinder, which is given by the formula SA = 2πrh + πr² (the first term represents the lateral surface and the second term the base).

Using the volume formula, we can find a relationship between r and h:

h = 10 / (πr²)

Now substitute this expression for h in the surface area formula:

SA(r) = 2πr(10 / (πr²)) + πr²
SA(r) = 20/r + πr²

To find the minimum surface area, differentiate SA(r) with respect to r and set the result equal to zero:

d(SA)/dr = -20/r² + 2πr

Now solve for r:

0 = -20/r² + 2πr
20/r² = 2πr
r³ = 10/π

Now take the cube root of both sides:

r = (10/π)^(1/3)

To find the height, substitute this value of r back into the expression for h:

h = 10 / (π((10/π)^(1/3))²)
h = (10/π)^(1/3)

The dimensions that require the least amount of material are r = (10/π)^(1/3) cm for the radius and h = (10/π)^(1/3) cm for the height.

Sam puts a cash deposit of $8,000 on a used car. the bank is charging sam an interest rate of 4.75% per year. how much interest will he pay to the bank at the end of 5 years?

Answers

At the end of 5 years, Sam will have paid $1,900 in interest to the bank. This calculation assumes that the interest rate remains constant and is applied on a simple basis, rather than being compounded over the 5-year period.

Sam makes a cash deposit of $8,000 on a used car and is charged an interest rate of 4.75% per year by the bank. To calculate the interest he will pay at the end of 5 years, we can use the formula for simple interest, which is I = P × R × T, where I is the interest, P is the principal (the initial deposit), R is the interest rate, and T is the time in years.

In this case, P = $8,000, R = 4.75% (or 0.0475 in decimal form), and T = 5 years. Plugging these values into the formula, we get:

I = $8,000 × 0.0475 × 5

I = $1,900

Sam will pay $1,900 in interest to the bank at the end of 5 years.

How to find interest rate?

The interest rate is 4.75% per year, which can be written as 0.0475 as a decimal. The amount of interest that Sam will pay after 5 years can be calculated using the simple interest formula:

Interest = Principal x Rate x Time

where Principal is the initial deposit, Rate is the interest rate, and Time is the length of time the interest is charged for.

In this case, the Principal is $8,000, the Rate is 0.0475, and the Time is 5 years. Plugging these values into the formula, we get:

Interest = $8,000 x 0.0475 x 5

Interest = $1,900

Therefore, Sam will pay $1,900 in interest to the bank at the end of 5 years.

Marshall and oliver went to an arcade where the machines took tokens. marshall played 10 games of skee ball and 8 games of pinball, using a total of 44 tokens. at the same time, oliver played 3 games of skee ball and 8 games of pinball, using up 30 tokens. how many tokens does each game require?

Answers

Each game of skee ball requires 2 tokens and each game of pinball requires 2 tokens.

Let the number of tokens required for each game of skee ball be x and for each game of pinball be y.

From the given information, we can form two equations:

10x + 8y = 44    ... (1)

3x + 8y = 30      ... (2)

Multiplying equation (2) by 3, we get:

9x + 24y = 90     ... (3)

Subtracting equation (1) from equation (3), we get:

- x + 16y = 46

Solving for x, we get:

x = 16y - 46

Substituting this value of x in equation (2), we get:

3(16y - 46) + 8y = 30

Simplifying and solving for y, we get:

y = 2

Substituting this value of y in equation (1), we get:

10x + 8(2) = 44

Solving for x, we get:

x = 2

Therefore, each game of skee ball requires 2 tokens and each game of pinball requires 2 tokens.

A baker makes 20 loaves of bread
each day. The loaves are either
white or brown.
The ratio of white loaves to brown
loaves is always 7 : 3.
After how many days would the
baker have made 180 loaves of
brown bread?

Answers

Every day, a baker produces 20 loaves of bread. The loaves come in white or brown. It would take him 30 days to make 180 loaves of brown bread.

Let the ratio be x,

We have been given the ratio of 7 : 3 in which 3 part is of brown bed.

So the number of brown bread will be 3x and white bread will be 7x.

Now, we have to find out the days for 180 loaves of brown bread. This means that 3x = 180. Now we will find out the value of x to find the total loaves of bread from this equation.

3x = 180

x = 180 / 3

x = 60

So, the total amount of bread = brown bread + white bread

Total amount of bread = 3x + 7x

= 10x

= 10 × 60

= 600

We know that in 20 loaves of bread are made in one day, so

time taken to make 600 loaves of bread = 600 / 20

= 30 days

Here is a triangular prism. 4 cm 5 cm 5 cm 10 cm 6 cm answer numerically. units have been provided a. what is the volume of the prism, in cubic centimeters? cm3 b. what is the surface area of the prism, in square centimeters? cm²​

Answers

A triangular prism is a three-dimensional shape with two parallel triangular bases and three rectangular faces. In this case, the triangular bases have sides of 4 cm, 5 cm, and 5 cm, while the rectangular faces have a length of 10 cm and a height of 6 cm.

To find the volume of the prism, we can use the formula V = Bh, where B is the area of the base and h is the height. The area of a triangle can be found using the formula A = 1/2bh, where b is the base and h is the height.

So, for the triangular base of this prism, we have:

A = 1/2(4 cm)(3 cm) = 6 cm²

The height of the prism is 5 cm, so:

V = Bh = (6 cm²)(5 cm) = 30 cm³

Therefore, the volume of the prism is 30 cubic centimeters.

To find the surface area of the prism, we need to calculate the area of each face and add them up.

The two triangular faces each have an area of:

A = 1/2(4 cm)(5 cm) = 10 cm²

And the three rectangular faces each have an area of:

A = (10 cm)(6 cm) = 60 cm²

So, the total surface area is:

SA = 2(10 cm²) + 3(60 cm²) = 200 cm²

Therefore, the surface area of the prism is 200 square centimeters.

ceiling. The angles that both lengths make with the ceiling are the same. The


tension in each length is 50 N. Determine the angle that the lengths of ropes make


with the ceiling.

Answers

The angle that the lengths of ropes make with the ceiling is 90 degrees.

To determine the angle that the lengths of ropes make with the ceiling for an object with a weight of 100 N suspended by two ropes with equal tension of 50 N, we can follow these steps:

1. Understand that the vertical forces must balance, meaning the sum of the vertical components of tension in each rope must equal the object's weight.

2. Recognize that the vertical component of tension in each rope can be calculated using the sine function and the angle, θ, between the rope and the ceiling: T_vertical = T * sin(θ).

3. Set up an equation using the information provided: 2 * (50 N * sin(θ)) = 100 N, where θ is the angle we want to find.

4. Simplify the equation: 100 * sin(θ) = 100 N.

5. Divide both sides by 100: sin(θ) = 1.

A food company is designing box for several products each box is a rectangular prism. The food company is now designing soup boxes. The largest box of soup will be a dilation of the smallest box using a scale factor of two. The smallest box must hold eight fluid ounces or about 15 in. ³ of soup. Find a set of dimensions for the largest box round to the nearest tenth

Answers

The set of dimensions for the largest box is: 4 in x 4 in x 3.8 in.

We know that the smallest box must hold 8 fluid ounces or 15 in³ of soup. Let's assume the dimensions of the smallest box to be x, y, and z.

Then, we have:

[tex]x * y * z = 15[/tex]

Now, the largest box will be a dilation of the smallest box using a scale factor of 2. This means that every dimension of the smallest box will be multiplied by 2 to get the dimensions of the largest box.

So, the dimensions of the largest box will be 2x, 2y, and 2z.

Now, we need to find the dimensions of the smallest box. We can start by solving the equation x * y * z = 15 for one of the variables, say z:

[tex]z = 15 / (x * y)[/tex]

Substituting this value of z in the expression for the dimensions of the largest box, we get:

[tex]2x * 2y * (15 / (x * y))[/tex]

Simplifying this expression, we get:

[tex]4 * 15 = 60[/tex]

So, the dimensions of the largest box are approximately 4 in by 4 in by 3.8 in (rounded to the nearest tenth).

Therefore, the set of dimensions for the largest box is: 4 in x 4 in x 3.8 in.
