The ratio of men to women working for a company is 4 to 7.If there are 52 men working for the company, what is the total number

11Alexandr11 [23.1K]

143 employees

Because

4 to 7 means that for every 4 men, there is 7 women.

To figure this out I first divided 52 by 4

52÷4=13

I then multiplied this number by 7

13×7=91

Now knowing there are 91 women I added them together

91+52=143

Consider the radical equation = c + 2. Which statement is true about the solutions c = 3 and c = –6?

Phantasy [73]

The inside of the radical must be greater than or equal to zero. When you plug in c=3, the answer is 5 >0. When c=-6, -4 <0. Therefore c=3 is true.

At the fair 4 employees were paid $8.75 an hour to work at a funnel cake stand. They worked 8 hours at regular pay then for 5 ho

nordsb [41]

Answer:

$125.25

Step-by-step explanation:

8.75*h+11.25*e

h is hours regular pay and e is extra pay for overtime. Since its an extra $2.50 for overtime, add that to the regular pay. Put in the hours:

$8.75*8+11.25*5$

Simplify by multiplying 8.75 by 8

$70+11.25*5$

Simplify by multiplying 11.25 by 5

$70+56.25$

Add

$70+56.25=126.25$

Since it says how much did each earn, as in individually, leave it as it is (unless regular pay was $2.18 an hour, which would be a rip-off). I'm pretty sure including the number of employees was meant to throw you off.
