I really need help with this please ! I don't understand it, and I have a quiz tomorrow
erik [133]
You can do this by finding a number close to it, and then finding out how to do it.

For example with 63(square root sign), find out what is close to it.

7x7=49 while 8x8=64

Because of this, we now know that it is between 7 and 8 but is also really close to 8.

Our number could be 7.9

Hope this helped!!!

An office has 150 employees, and 30 of the employees work the night shift. What percentage of the employees work the night shift
Zanzabum
<h2>Answer:</h2>

The percent of employees who work in the night shift are:

                                     20%

<h2>Step-by-step explanation:</h2>

Total number of employee in the office are: 150

Number of employee who work in the night shift are:  30

The percent of the employee who work in the night shift is calculated as follows:

\dfrac{\text{Number\ of\ people\ working\ in\ the\ night\ shift}}{\text{Total\ number\ of\ employees}}\times 100

Hence, on putting the value in the above formula we get:

=\dfrac{30}{150}\times 100\\\\\\=\dfrac{1}{5}\times 100\\\\\\=20\%

            Hence, the answer is:

                          20%
