The correct answer is letter choice E.
The answer is letter choice E because 4.9 times 10 to the 2nd power which is 490. Then you calculate 6.8 times 10 to the 3rd power which is 6800.
After you calculate these two equations you then add the answer which is 6800+490 which equals (=) 7290.
Letter choice E is the only accurate answer to equal to 7290. How I figured this out is by calculating 7.29 times 10 to the 3rd power the correct answer to this equation is 7290.
It matches equivalently with the problem so the answer is E.

If 12 is replaced with 3 in the following set, what will happen to the value of the range? 28, 45, 12, 34, 36, 45, 19, 20
anzhelika [568]
The range is the number of units between the smallest and largest number. organising your numbers from smallest to largest:

12, 19, 20, 28, 34, 36, 45, 45

in your case 12 is the smallest number of your set. lowering it to 3 would increase the distance between the two numbers, therefore increasing the range

hope that helps :)

A square is changed into a new rectangle by increasing its width by 2 inches and decreasing its length by 2
solniwko [45]

Answer: The area of the square is 64 square inches and the area of the new rectangle is 60 square inches. The square's area is 4 inches larger than the rectangle.

Step-by-step explanation: If a side length of the square measures 8 inches, then its area can be calculated as follows;

Area = L x W

The length and the width both measure 8 inches (all sides of a square are equal in length).

Area = 8 x 8

Area = 64

Also, the the new rectangle is formed by increasing the width of the square by 2 inches (that is 8 + 2 = 10), and decreasing the length by 2 inches (that is 8 - 2 = 6). The area of the new rectangle is calculated as follows;

Area = L x W

Area = 10 x 6

Area = 60

Therefore the area of the square is 64 square inches and the area of the rectangle is 60 square inches. The area of the square is 4 inches larger than that of the rectangle.
