The radius of the sphere is 9 inches. Which equation can be used to find the surface area of the sphere?

Answers

Answer:

Option (2)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area = 4πr²

Here 'r' = Radius of the sphere

We have to calculate the surface area of a sphere with radius r = 9 inches.

By substituting the value of r in the formula,

S = 4π(9)²

Therefore, Option (2) will be the correct option.

Answer:

B. S = 4 pi r squared = 4 pi (9) squared

Rick is taking a 1-mile ride on his bicycle. For each rotation of his tire, he travels 72 inches. How many rotations will his tire make during the 1-mile trip?
O 73 rotations
O 83 rotations
O 780 rotations
O 880 rotations
SHOW YOUR WORK!!!

Answers

Answer:

880 rotations or D

Step-by-step explanation:

72 inches = 72 / 12 = 6 feet

1 mile = 5280 feet

1 rotation covers 6 feet

x rotations covers 5280 feet

1/x = 6/5280 Cross multiply

6x = 5280 * 1 Divide by 6

x = 5280 /6

x = 880

Find the area of a circle with diameter 12 m.
Use the value 3.14 for n, and do not round your answer.
Be sure to include the correct unit in your answer.

Answers

Answer:

113.04m²

Step-by-step explanation:

Area of circle: [tex]\pi[/tex] × r²

Radius = [tex]\frac{diameter}{2}[/tex]

We can just apply the formula to the question:

Area of circle = 3.14 × ([tex]\frac{12}{2}[/tex])²

= 3.14 × 36

= 113.04m²

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Two lines are drawn in the same plane.

If the two lines intersect then the angle between the line is 90 degrees.

The condition for the lines to be perpendicular will be two lines that intersect and form right angles.

Then the correct option is B.

You want to know about the dining habits of college students in the US. Since you do not have resources to survey all college students in the nation, you take a random sample of 1501. You learn that, on average, they eat out 4 times per week. Also, these sample data are generally distributed about the average of 4 times, by 1.5 times per week. 1. What is the average times per week that college students across the nation eat out

Answers

Answer:

the average times per week that college students across the nation eat out lies within these 95% confidence interval

[tex] 3.938 < \mu < 4.062 [/tex]

Step-by-step explanation:

From the question we are told that

The sample size is n = 1501

The sample mean is [tex]\= x = 4[/tex]

The standard deviation is [tex]\sigma = 1.5[/tex]

From the question we are told the confidence level is 95% , hence the level of significance is

[tex]\alpha = (100 - 95 ) \%[/tex]

=> [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is

[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Generally the margin of error is mathematically represented as

[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]

=> [tex]E = 1.96 * \frac{1.5 }{\sqrt{1501} }[/tex]

=> [tex]E = 0.06196 [/tex]

Generally the estimate for average times per week that college students across the nation eat out at a 95% confidence is mathematically represented as

[tex]\= x -E < \mu < \=x +E[/tex]

[tex]4 -0.06196 < \mu < 4 + 0.06196[/tex]

=> [tex] 3.938 < \mu < 4.062 [/tex]

Hence the true average times per week that college students across the nation eat out lies within this interval

Proportions 6. A certain salsa is made with 6 parts tomato and 2 parts bell pepper. How many cups of tomato should be combined with 1.5 cups bell pepper? Write a proportion, then solve.

Answers

Answer:

4.5 cups of tomatoes should be combined with 1.5 cups of bell peppers.

Step-by-step explanation:

Given that the salsa is made with 6 parts tomato and 2 parts bell pepper.

Let t be tomatoes and b be bell peppers

The proportion will be:

t:b

The ratio of tomatoes to bell pepper will be:

6:2

This ratio simplifies to 3:1

This means no matter how much more the tomatoes and peppers are, the simplified ratio will be same.

Now the bell peppers are 1.5 cups then the proportion will be:

[tex]t:b::t:b\\6:2::t:1.5\\\frac{6}{2} = \frac{t}{1.5}\\3 = \frac{t}{1.5}\\t = 1.5 * 3\\t =4.5[/tex]

Hence,

4.5 cups of tomatoes should be combined with 1.5 cups of bell peppers.

6. To solve the equation in the box for the
value of x, Michele started by adding 5 to both
sides. To get the correct answer, what must
Michele do next?
A divide both sides by 10
B. divide both sides by 3
C. multiply both sides by 10
D. multiply both sides by 3

Answers

After adding 5 to both sides what did Michele get? Let's see

[tex]3x-5 + 5 = -10 + 5\\3x= -5[/tex]

If she wants to find the value of [tex]x[/tex] then she needs to have only the variable [tex]x[/tex] on the left hand side. What she must do so that [tex]3x[/tex] becomes just [tex]x[/tex]? What do you have to do to the number 3 so it becomes a 1? That's right, she must divide by 3!

So, after dividing both sides by 3:

[tex]\frac{3x}{3} = \frac{-10}{3} \\\\\boxed{x=\frac{-10}{3}}[/tex]

Thus, the correct answer is letter B

Tori had a $300 unpaid balance after last month's payment on her account. Her annual percentage rate is 21%. The minimum payment due is $25. How much of that is interest for one
month on the unpaid balance?

Answers

Answer:

After the passage of a month, the interest that Tori must pay will be $ 4.81.

Step-by-step explanation:

Given that Tori has an unpaid balance of $ 300 on her credit card, and that said credit card has an annual interest of 21% on the unpaid balances, considering that the minimum payment is $ 25, to determine how much she should pay after a month of After your debt, it is necessary to perform the following calculation:

12 = 21

1 = X

21/12 = X

1.75 = X

((300 - 25) x 1.75 / 100) + 300 = X

4.81 + 300 = X

304.81 = X

Thus, after the passage of a month, the finance charge that Tori must pay will be $ 4.81.
