Question

QUICK!!! TAKING A TEST RN!!! 30 POINTS!!!A water tank has 22 gallons of water. It begins to receive 26 gallons per hour for a number of hours. If the tank needs to fill to at least 516 gallons, which of the following is the minimum number of hours the tank should continue filling?

Answer 1

Hey there!!

Let's take 'h' as the number of hours.

The volume already present is "22" gallons.

Hence, this would become the y-intercept.

... ( 0 , 22 )

... The slope would be 26

Hence, y would be 516 and m would be 26 and x would be h.

Slope-intercept form :-

y = mx + b

( m is the slope and b is the y-intercept )

... 516 = 26h + 22

... 516 - 22 = 26h

... 494 = 26h

... h = 494 / 26

... h = 19

Hence, the number of hours would be 19.

Hope my answer helps!
