Complete question :

In a​ company, ​60% of the workers are men If 125 people work for the company who​ aren't men​, how many workers are there in​ all? Use pencil and paper. Show two different ways that you can solve this problem.

Answer:

313

Step-by-step explanation:

Given that :

Percentage of workers who are men = 60%

Number of workers who aren't men = 125

Hence, percentage of workers who aren't men = (100% - 60%) = 40%

Thus;

40% of workers = 125

If ;

0.4 = 125

100% of the workers x

0.4 = 125

1 = x

Cross multiply

0.4x = 125

0.4x / 0.4 = 125 / 0.4

x = 312.5

Hence, total number of workers = 313

Answer:

D

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 12² = 13²

a² + 144 = 169 ( subtract 144 from both sides )

a² = 25 ( take the square root of both sides )

a = [tex]\sqrt{25}[/tex] = 5 → D

I use the expression 3(2w - 10) to determine how many copies I need to make of a worksheet (w). If w = 20, how many worksheet copies do I need to make?

Answers

Answer: The number of copies of worksheet needs to be done = 90

Step-by-step explanation:

The expression used to evaluate the number of copies need to make of the worksheet (denoted as 'w') is given as 3(2w - 10).

If w=20, then the number of copies need to make of worksheet  = 3(2(20)-10)

i.e. the number of copies need to make of worksheet= 3 (40-10)

i.e. the number of copies need to make of worksheet= 3 (30)

i.e. the number of copies need to make of worksheet= 3 x 30

i.e. the number of copies need to make of worksheet= 90

Hence, if w = 20,  then the number of copies of worksheet needs to be done = 90

Answers

Answer:

use division

Step-by-step explanation:

Answer:

525

Step-by-step explanation:

first we need to work out the percentage of the children who attended  to to do this we need to add 47% with 32% which is 79%. Then you need to take away 79% from 100% which is 21%. After that you now know that 21% is the children who attended but you wanted to know how many children so to work this out you would find 21% of 2500 which would give you 525.
