the volume v of a tank varies directly with its height h a tank 12 ft High holds 300 cubic feet write an equation relating v & H

v varies directly with height means

v/h=k were k is a constant

or also h/v=k where k is a constant (this is a different k than previous)

so if h=12 and v=300 then

h/v=12/300=1/25=k

so the relationhip could be h/v=1/25

if you di v/h, then

v/h=300/12=25/1=25=k

so the relationship could be v/h=25
