I believe it's C)14.
Because a beach volleyball is a sphere, so the volume formula is V= 4pi r^3/r
so the answer would be <span>24,429.024 </span>
First equation 2(4X -5y = 4)
8X -10y = 8
Elimination 8x -10y =8
-8x + 9y =-8
-y =0
-1(-y =0)
y =0
8x -10(0) =8
8x =8
(8x =8)/8
x = 1
8+4=12
9+7=16
12^2=144
16^2=256
144+256=400
square root of 400 is 20
therefore the distance from (8, -7) to (-4,9) is 20.
She will have about 3 minutes 20 seconds to work on each exercise because 1/3 of an hour is 20 minutes. You can find that by dividing 60 by 3. Next you have to divided 20 by 6. Your answer will be 3.33333333333. So you would get about 3 minutes 20 seconds
