She will have about 3 minutes 20 seconds to work on each exercise because 1/3 of an hour is 20 minutes. You can find that by dividing 60 by 3. Next you have to divided 20 by 6. Your answer will be 3.33333333333. So you would get about 3 minutes 20 seconds
In order to solve this, you need to put it into a fraction form.
First for every 225 employees there's 27 supervisors.
25 x
___ = ___
225 252
I got the 252 by adding 225+27(who are the new employees)
So then you need to cross multiply. And get them to equal the same number.
So 25×252= 6,300
Then Divide 6,300 by the old denominator 225.
6,300÷225= 28 new employees
Therefore there will be a total of 28 employees.
Hope this helped!

In the expression, the real number a equals 12 and the real number b equals -16.
<h3>How to explain the information?</h3>
It should be noted that the expression given is:
= (4 - 2i)²
Therefore, we need to expand the expression. This will be:
= (4 - 2i)(4 - 2i)
= 16 -8i -8i + 4i²
= 16 -16i +4i²
Substitute -1 for i²
= 16 - 16i + 4(-1)
= 16 - 16i - 4
= 12 - 16i
Therefore, the value of the expression is 12 - 16i.
