The ratio of men to women working for a company is 4 to 5 . if there are 90 women working for the company, what is the total number of employees?

Step-by-step explanation

The answer would be 162 total number of employees.

The steps would be to cross multiply and divide then add the number of women to the number you get after cross multiply and divide.

4 =x

5 =90

so now you multiply 4 and 90 you should get 360 then take 360 and divide by 5 and you get 72. the number of women was already given so there are 90 women ,then we just got the number of men which was 72 then you just add 90+72 and there is 162 employees.

Hopefully this helps

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
