A swimming pool is 50 m long and 20 m wide. Its depth decreases linearly along the length from 9 m to 1 m. It is initially empty and is filled at a rate of 1 m/min. How fast is the water level rising 90 min after the filling begins?
How long will it take to fill the pool?

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
