plastic = 45
metal = 30
Step-by-step explanation:
Answer:
p = 9 when q = 5.
Step-by-step explanation:
p is inversely proportional to the square of q
This means that:

In which k is a constant multiplier.
p is 25 when q is 3
We use this to find k.



So

Determine p when q is equal to 5.

p = 9 when q = 5.
6x/-4 = 6(-1/2)
6x/-4 = - 3...multiply by -4
6x = -3 * -4
6x = 12
x = 2
