Which is the same as 98.52 ÷ 10?

Answers

Answer 1
Answer: moving the decimal over one space to the left. (9.852)

Explanation:
If you multiply a decimal by 10 the decimal point will move one space to the right to make a bigger number. But, if you divide by 10, it will move one space to the left to make a smaller number. (÷ means left, x means right) The The rule is, however many 0’s you have after the 1, that is how many spaces you move your decimal point. For an example if I wanted to multiply or divide a decimal by 100, I would move the decimal point 2 spaces over instead of just one because the number 100 had two 0’s after the one.This rule will not work with numbers like 20, or 150, because they are not multiples of 10 like the other numbers. Numbers that will work are 10, 100, 1000, 10000, 100000 and so on.

Sorry this is so long, I just wanted to make sure you understand because I had trouble with it when I was learning it.

A typical stone on the lowest level of the great pyramid in Egypt was a rectangular prism 5 feet long by 5 feet high by 6 feet deep and weighed 15 tons what was the volume of the average stone how much did one cubic foot of this stone weigh

Answers

To find the volume, you need to do length times width times height
SO you have to do 5 times 5 times 6
The volume is 150 cubic feet
Since 150 cubic feet of this rectangular prism is 15 tons
you can do 15 divided by 150
so one cubic feet of this stone sculpture weight 0.1 tons
Btw, a pyramid is  a triangular structure, not rectangular

Art supplies in Washington, D.C. Cost 28. If the sales tax is 6%, what was the total cost of supplies?

Answers

If the art supplies cost $28 and the sales tax is 6%, you must find 6% of 28. To do this, you must multiply 6 by 28, and then divide by 100. The result is 1.68. Then, to find the final cost, add the 6% of 28 (which is 1.68) to the original cost, $26, which is $29.68
Sales tax is:
$28.00* (6/100)= $1.68

$28.00+ $1.68= $29.68

The total cost of supplies was $29.68.

Polygon Y is a scaled copy of Polygon X using a scale factor of 1/3 Polygon Y's area is what fraction of Polygon X's area?

Answers

Answer:

1/9. Because the area is measured in units squared, then you have to square 1/3 which is 19th.

Step-by-step explanation:

The area is measured in squared units. You have to square 1/3 which is 1/9. (1)/(3) ^2= (1)/(3) ((1)/(3))

Answer:

1/9

Step-by-step explanation:

SideY/sideX = ⅓

AreaY/AreaX = (sideY/sideX)²

= (⅓)²

AreaY/AreaX = 1/9
