A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 113 larger, by what is the percent of increase in the area of the picture

27.7% larger

Step-by-step explanation:

6 x 113% = 6.78

9 x 113% = 10.17

Old Area = 9 x 6 = 54 sq in

New Area = 6.78 x 10.17 = 68.95

(New - Old) ÷ Old = .277 = 27.7%

y -5 = (-1/4)(x + 8)

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
