PEMDAS
parenthasees first
insid there is an exonent

The ratio of Sam age to Hanks is 5 to 3. If the sum of their ages is 24, how old is Hank?

Answers

How to solve this:

1. 5x + 3x = 24
2. x(5+3) = 24
3. x = 24/(5+3)
4. x = 24/(8)
5. x= 8
6. 5*3 = 15 (Sam) 3*3 = 9 (Hanks)

15 and 9 are the two ages so so hank is 9.

To print a telephone book,565 sheets of paper were used. If the book is 2.6 inches thick,what is the thickness of each sheet of paper.? Round to the nearest thousandth of an inch.

Answers

Using division, the thickness of each sheet of paper is 0.005 inches

What is the thickness of each sheet of paper?

To find the thickness of each sheet of paper, divide the total thickness of the telephone book by the number of sheets used.

Thickness of each sheet of paper = Total thickness / Number of sheets

Thickness of each sheet of paper = 2.6 inches / 565 sheets ≈ 0.004602 inches

Rounded to the nearest thousandth of an inch, the thickness of each sheet of paper is approximately 0.005 inches.

The telephone book is 2.6 inches thick, with 565 sheets of paper.

What this means is 2.6 inches is the thickness of 565 sheets of paper.

To find the thickness of each sheet of paper, all we do is:

2.6 ÷ 565

This gives us quite a large answer:

0.0046017699

To round to the thousandth place, we look at the third number past the decimal and look to see if we need to round up or round down.
The number to the right of our digit in the thousandth place lets us know (in this case) to round up.

Therefore, 0.0046017699 rounded to the nearest thousandth is:

0.005
Don't forget to label (inches)
