Avalve in a full 6000 gallon water tank is slowly opening. water flows out of the tank through the valve. the flow rate in gallons per hour is given by the function f(t)=300t2 where t is in minutes. how much water flows out of the tank in the first 7 minutes? how many minutes does it take for the tank to empty completely?

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
