Answer 1

Answer: $36* 100 = 3600\n\n8 * 1000 = 8000\n\n5.6 * 10 = 56\n\n5.6 * 100 = 560\n\n5.6 * 1000 = 5600\n\n2.12 * 100 = 212$

When you multiply by 10, 100, or 1000, you must move the decimal place over by how many zeroes there are. Once there is no more decimals, you add 0's to the end of the number until you are done.

For example, 5.6 x 1000

1000 has 3 zeroes.

That means we need to move the decimal spot 3 times.

5.6 x 1000 = 56 x 100

We got rid of the decimal but we still have 2 zeroes left. So now we just add 2 zeroes at the end of the number.

5.6 x 1000 = 56 x 100 = 5600

I hope that helps! :)

If the exponent is 3 and the base is 2 whats the simplified expression

Answers

If the base is 2 and the exponent is the the expression would look like this → 2³. In order to simplify it, you have to multiply the base number by the number of the exponent.

2×2×2=8
Therefore, the simplified expression would be 8.

I hope this helped.

By definition of the exponent
2³= 2*2*2= 8

You buy a bookshelf. The label on the box says the bookshelf is 51 inches tall. How tall is it in feet?

Answers

A feet is 12 inches.

$51/12=4.25$

i think you take 51 and divide by 12 bc there are 12 inches in a foot. if that's right then the answer should be 4.25 feet.

Which inequality has the solution shown below?

Answers

The answer is 0.2x + 5 > 2

Answer:

0.2x + 5 > 2

Step-by-step explanation:

The arrow is pointing to the right so immediately you know that the sign will be greater than (>). So we can eliminate the choices, 0.3x + 8 < 3 and 0.4x +7 < 1.

Now looking at the two options that are left, we can simply solve them.

0.2x + 5 > 2

Subtract 5 on both sides

0.2x > -3

Then divide 0.2 on both sides and you're left with:

x > -15

We don't need to solve the other inequality because we know that the arrow is pointing to the right, suggesting that x is greater than -15.

Hope you find this helpful :)
