<span>Itll take four pumps 6 hours to fill the pool with water.
And heres how we get to that conclusion:
Logically, the thing that would make calculating how much time would it take for four (or any other number) pumps to fill the pool much, much simpler, would be knowing how much water goes through one pump in one hour.
And luckily, this can be calculated from the data given above.
Basically, if three pumps fill the pool in 8 hours, this means one pump fills 1/3 of the pool in this time.
Now, since the exact amount of water goes through the pump at any point, this means that in order to fill 1/3 of the pool with one pump, thered be 1/8 of the total amount of water that goes through it (in this case, 1/3 of the pool) every hour.
Or, one pump would fill 1/8 * 1/3 in one hour. This is 1/24.
And its just smooth sailing from here on.
If one pump fills 1/24 of the pool in an hour, four pumps fill 4*1/24, or 1/6 in the same time.
So if the four pumps fill out 1/6 of the pool in one hour, theyd need to do this 6 times to fill the whole pool.
Or, rather, 6 hours.</span>
Explanation:
The question is given below as
We will apply the pedmas rule below
P – Parentheses [{()}]
E – Exponents (Powers and Roots)
MD- Multiplication and Division (left to right) (× and ÷)
AS – Addition and Subtraction (left to right)
By applying the rule, we will have
![\begin{gathered} \begin{equation*} [1+(11+31)\div6)\times5 \end{equation*} \\ [1+\frac{42}{6}]\times5 \\ [1+7]\times5 \\ 8\times5=40 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cbegin%7Bequation%2A%7D%20%5B1%2B%2811%2B31%29%5Cdiv6%29%5Ctimes5%20%5Cend%7Bequation%2A%7D%20%5C%5C%20%5B1%2B%5Cfrac%7B42%7D%7B6%7D%5D%5Ctimes5%20%5C%5C%20%5B1%2B7%5D%5Ctimes5%20%5C%5C%208%5Ctimes5%3D40%20%5Cend%7Bgathered%7D)

Answer:
The hourly wage is $8.55 per hour
Step-by-step explanation:
Step 1: Determine the expression for the gross pay
Total gross pay=(Unit rate per hour×number of hours(≤40))+(Overtime rate×number of overtime hours)
where;
Total gross pay=$380.48
Unit rate per hour=x
Number of hours=40 hours
Overtime rate=x×(1 1/2)=1.5 x
Number of overtime hours=3 hours
Step 2: Replace to solve for hourly wage
380.48=(x×40)+(1.5 x)×3
40 x+4.5 x=380.48
44.5 x=380.48
x=380.48/44.5
x=8.55
The hourly wage is $8.55 per hour
Answer:
132.54cm²
Step-by-step explanation:
We can use the formula [ C²/4π ] to solve.
= 40.8²/4π
= 1,664.64/12.56
≈ 132.54cm²
Best of Luck!
