The time, t, required to empty a tank varies inversely as the rate, r, of pumping. If a pump can empty a tank in 2.5 hours at a rate of 400 gallons per
minute, how long will it take to empty a tank at 500 gallons per minute?

2 hours

Step-by-step explanation:

2.5 * 400 = 1000

1000 / 500 = 2

Hope this helped!

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
