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!

Use the quadratic formula to solve x² + 9x + 10 = 0.<br><br> What are the solutions to the equation?
jok3333 [9.3K]

Answer:

-1.30\ and\ -7.70 (2 decimal places)

Step-by-step explanation:

Quadratic Formula: x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

-----------------------------------------------

x^2+9x+10=0

Plug in values:

x=\frac{-9\pm \sqrt{9^2-4\cdot \:1\cdot \:10}}{2\cdot \:1}

First value of x:

x=\frac{-9+\sqrt{41}}{2}=-1.30 (2 decimal places)

Second value of x:

x=\frac{-9-\sqrt{41}}{2}=-7.70 (2 decimal places)

Please help me with this it’s due today .
USPshnik [31]

For question 1:

Since each person is going to eat 1/4 of pizza and there are two of them, there are going to be 8 slices. There are 5 people eating, that's 5 slices gone, leaving 3.

It would be <u>D.) 3/4 pizza</u>

For question 2:

three people order the same meal. Now, if I'm correct, the meal total is AFTER the coupons were used. so that would bring total cost up to $30.75.

Divide that by 3 for all three friends:

30.75/3 = <u>D.) $10.25</u>
