a certain gas will escape from a storage tank according to the formula e=180√(p),
where e represents the amount escaping per minute in gallons, and p represents
the pressure in pounds per square inch.
What is the pressure on the gas when about 225 gallons per minute are escaping?
:
Replacing e with 225, we have
180sqrt%28p%29 = 225
divide both sides by 180
sqrt%28p%29 = 225%2F180
sqrt%28p%29 = 1.25
square both sides
p = 1.25%5E2
p = 1.5625 psi

Check this on a calc: enter 180sqrt%281.5625%29 results: 225
