A copy machine makes
IrinaK [193]
This problem can be represented in a formula with fractions. To make it more simple, we are converting 5m30s to just pure seconds, which = 154 copies in 330 seconds.

You set up the formula like this: 154/330 = x/60. (it is x/60 because you want to know the x amount of copies per 60 seconds)

Cross multiply, you get 330x = 9240. Divide both sides by 330, you get:

 x = 28 copies.

The final answer is 28 copies per minute

Answer:

C. 7790.83 cm^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the radius is 12.3

Using 3.14 for pi  (This will give us an approximation, not an exact value)

V = 4/3(3.14) (12.3)^3

   =7790.82984 cm^3
