The surface area of a soccer ball is 254.5 in?.
What is the radius to the tenths' place?

Answers

Answer 1

Answer:

4.5 inches

Step-by-step explanation:

Use the formula for the surface area of a sphere, SA = 4[tex]\pi[/tex]r²

Plug in the surface area and solve for r, the radius:

SA = 4[tex]\pi[/tex]r²

254.5 = [tex]\pi[/tex]r²

20.25 = r²

4.5 = r

So, the radius is approximately 4.5 inches

Find the mean, median, and mode of 12, 9, 17, 15, 10

Answers

Answer:

Mean: 12.6

Median: 12

Mode: 9, 10, 12, 15, 17

Step-by-step explanation:

Mean: To find the mean you have to add up all your terms and divide your result by the number of terms you have. ((12+9+17+15+10) / 5)

Median: To find the median you have to organize your terms from least to greatest and then find your center term. (12)

Mode: Normally to find your mode would be to organize your terms from least to greatest and see which of your terms occurs the most. In this case all terms occur only once, making all your terms the mode.

8. We want to solve for a of the trapezoid area formula.

A = [tex]\frac{h}{2} (a + b)[/tex]

First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].

[tex]\frac{2A}{h}[/tex] = a + b

Now, we need to subtract b from both sides.

[tex]\frac{2A - b}{h}[/tex] = a

We get the answer to be:

I. a = [tex]\frac{2A - b}{h}[/tex]

Solve the proportion 40/z+1 = 15/6

Answers

Answer:

z = 15

Step-by-step explanation:

[tex] \frac{40}{z + 1} = \frac{15}{6} \\ [/tex]

Cross multiply

That's

[tex]15(z + 1) = 40(6) \\ 15z + 15 = 240[/tex]

Send 15 to the right side of the equation

[tex]15z = 240 - 15 \\ 15z = 225[/tex]

Divide both sides by 15

[tex] \frac{15z}{15} = \frac{225}{15} \\ [/tex]

We have the final answer as

z = 15

Draw the angles, write and equation and solve the measures of each angle.

HELP PLEASE

Answers

Answer:

70 and 110

Step-by-step explanation:

First angle -- 2x

Second angle -- 3x + 5

Therefore,

2x + 3x + 5 = 180

5x = 175

x = 35

Therefore, 2x -- 70
