Estimate. Then find the difference.

324-285=

Answers

Answer 1
Answer:

Answer:

30

Step-by-step explanation:

324-285

WE can estimate the numbers to nearest tens or nearest hundreds

LEts estimate the numbers to nearest  tens and find the difference

324 round to nearest tens is 320

285 have 5 in once place that is equal to 5 so we add 1 with 8

285 round to nearest tens is 290

Now we find the difference

320- 290= 30

The difference is 30

If we estimate to nearest hundred then 300 -300 becomes 0
Answer 2
Answer:             If rounding to the hundreds
To estimate round 324 and 285 to the closest hundred.
300 - 300
Then subtract 300 - 300 =
0
               If rounding to the tens
To estimate round 324 and 285 to the nearest ten.
320 - 290 
Then subtract 320 - 290 =
30

How do i find the height of an object if I only have the area, the length, and the width?

Answers

Well technicaly speaking wouldnt the width or the length be the height? Depending on what way the object is facing and is and what sides the length and width are applied to. Enjoy!=) 
area=legnth times width

normally you would subsiutte legnth for height when solving for the area of a triangle

if you have legnth, witdth, and height, then you have volume like volume of a fish tank

so
area=legnth times width
if you meant volume then if you have the area then
area=legnth times width
volume=legnth times width times height
so to solve for height when you know volume, area, legnth , width, then
divide both sides by (legnth times width or area)
volume/(legnth times width)=height

Explanation:

The process is very similar. We multiply the digits the same was as we would multiply whole numbers. We start at the last place value and multiply, working our way left with each line. At the end of the process, we add the lines together.

The difference comes with the decimal point. After we are finished multiplying, we count the number of digits behind a decimal (total) in the problem. This is how many digits will be behind a decimal in the answer.
