PLSSS? i dont really get it<br> Thanks

Answer:

A) 83 km/ hour

B) 2/7 penalties / game

C) $16 / CD

D) 9 donuts / box

Step-by-step explanation:

For this question they are asking for the distance traveled in 1 hour.

Since 747km was travelled in 9 hours, we divide 747 by 9 to find the distance travelled in 1 hour

747 ÷ 9 = 83

The unit rate is 83 km/ hour

You have to find the number of penalties per game

Like before divide 10 by 35:

10 ÷ 35 = 10/35 = 2/7

2/7 penalties / game

Find the cost of 1 CD :

64 / 4 = 16

$16 / CD

Find the amount of donuts per box:

72/8 = 9

9 donuts per box

The diameter of the moon is approximately one fourth of the diameter of the earth.

netineya [11]

Answer:

Step-by-step explanation:

Area of a sphere is $4\pi d^{2}$

let d be the diameter of the moon and D be the diameter of the earth

d = 1/4 D

Area of Earth = $4\pi D^{2} = 4\pi (\frac{d}{4} )^{2} = 4\pi \frac{d^{2} }{16} = \pi \frac{d^{2} }{4}$

Area of moon = $4\pi d^{2}$

$\frac{Area of moon}{Area of Earth} = \frac{1}{16}$
