Remark work with the two numbers that are 10^4 first. Then add in the one that goes to 10^3
Method one
You could change these all to integers and then take it back to scientific notation.
83 000
<u>-19 000</u>
64 000
<u>- 2 500
</u> 61 500 <u /><<<<<< answer
Method two
Keep the scientific notation.
8.3 * 10^4
<u>-1.9 * 10^4</u>
6.4 * 10^4
<u>- .25*10^4</u> Note the powers of ten must be the same.
6.15*10^4 <<<<<<<< answer
<u>
</u>Either method works.
<u>
</u>You could use your calculator to get the right answer. I'm not sure all calculators retain the scientific notation. Test yours to see what it does. Enter 8.3*10y^x 4 *1 =
<u>
</u>Your calculator might have x^y or ^ to record powers. You may also have EE and one of your keys.
<u>
</u>See if your calculator returns 8.3*10^4 or if it returns 83000<u>

Answer:
quadrilateral JDLK
Step-by-step explanation:
It didn't change size
It didn't change angle values or side lengths
It is the same shape, which means it is a rigid transformation

Answer:
The Possible dimension of the ring could be;
20 ft × 60 ft
25 ft × 48 ft
30 ft × 40 ft
60 ft × 20 ft
48 ft × 25 ft
40 ft × 30 ft
Step-by-step explanation:
Given:
Number of skaters = 30
Area for each skater = 40 sq ft
We need to find the dimension of rectangular ring the are going to build.
Now we know that they building the skating ring such that they all can use at same time.
Hence if the all use at same time then we will find the total area first.
Total area can be calculated by multiplying Number of skaters with area required for each skaters.
Framing the equation we get;
Total area = 
Hence The total area of the rectangular ring would be 1200 sq. ft.
Now we know that Total area is equal to product of length and width.
1200 can be written as = 20 × 60, 25 × 48, 30 × 40,60 × 20,48 × 25,40 × 30
Hence the Possible dimension of the ring could be;
20 ft × 60 ft
25 ft × 48 ft
30 ft × 40 ft
60 ft × 20 ft
48 ft × 25 ft
40 ft × 30 ft
