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
Volume = pi * radius^2 * height
= 3.14 * 5^2 * 13
= 3.14 * 25 * 13
= 1020.5
Answer:
x=-2
Step-by-step explanation:
subtract 8 from both sides you get -4x=-8
divide by -4
you get x=-2
