375L-240L=135L
135÷0.6=81
The pump must work for 81 min or 1hr and 21 min until the tank reaches 240L
Answer:

Step-by-step explanation:
6(8-x)(x+4)=0
(48 -6x )(x+4) = 0
48x +192 -6x^2 -24x = 0
6x^2 -24x -192=0
using quadratic formula:

a= 6 b= -24 c= -192
we have:

Your equation for the first point will be y=x+50
Explanation...
The x is zero so we just only put x. The y is 50 so we input a 50 giving us y=x+50.
Your equation for the second point will be y=2x+100.
Explanation...
Your slope is 2 so we input that and the y intercept is 100 giving us the equation y=2x+100.
Your equation for the third point will be y=4x+150
Explanation...
Your slope is 4 so we input that. Your y intercept is 150 so we input that. It gives us the equation y=4x+150.
yes it would be 24 feet tall
