A rectangular swimming pool with a flat bottom is 20 feet by 12 feet. How long will it take to fill the swimming pool to 5 feet
2 answers:
The given dimensions of the rectangular swimming pool are =
Length = 20 feet
Width = 12 feet
Height upto which the water should be filled up = 5 feet
So, the total volume of water needed to fill the pool will be =
cubic feet
The water is pumped at a speed of = 30 cubic feet per minute.
So, to fill 1200 cubic feet, the time taken will be =
Hence, it will take 40 minutes to fill the pool.

We know that the percentage amount of any number can be found by first converting the the given percentage to a fraction and then multiplying it by the given number. Thus, in our case, the exact value, that is 48% of 1165 can be calculated as follows:
We know that
Therefore, 48% of 1165 can be re-written as:
This can be calculated as [tex]0.48\times 1165=559.2[/tex
Therefore The exact value that is 48% of 1165 is 559.2
The approximate solution to the given system of equations, considering the graph, is given as follows:
D. .
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
On a graph, the solution of a system of equations is given by the intersection between the curves. In this graph, the intersection of the two curves happen close to x = -3.25, y = 2.5, hence the solution is approximated by:
D.
