Question 254338
From this sentence, we can create a direct variation formula:
The volume, V, of a tank varies directly with its height, h
{{{V = kh}}}
step 1 - put in the numbers you are given to find k. the numbers were
h = 12, V = 300. SO, we get
{{{300 = k*12}}}
solving for k, we get
K = 75.
step 2 - rewrite the equation with your new k value as
{{{V = 75h}}}
we are done.
