Last year there were 225 employees and 25 supervisors at Corpcon Company. If 27 more employees are hired, how many supervisors n
MrRa [10]
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!

Which two equations would be most appropriately solved by using the zero product property? Select each correct answer.
LekaFEV [45]
The zero product property tells us that if the product of two or more factors is zero, then each one of these factors CAN be zero.

For more context let's look at the first equation in the problem that we can apply this to: (x-3)(x+4)=0

Through zero property we know that the factor (x-3) can be equal to zero as well as (x+4). This is because, even if only one of them is zero, the product will immediately be zero.

The zero product property is best applied to factorable quadratic equations in this case.

Another factorable equation would be 2x^{2}+6x=0 since we can factor out 2x and end up with 2x(x+3)=0. Now we'll end up with two factors, 2x and (x+3), which we can apply the zero product property to.

The rest of the options are not factorable thus the zero product property won't apply to them.

You would use 539 and square it on you cal. just once. Then once you do that the answer is not going to be a whole number it is going to have a decimal, so the answer would be 23.22.
