Estimate the percent of decrease. original population: 1,503 new population: 1,356 a. 1% b. 10% c. 13.5% d. 15%

Percentage in decrease = 10 %

Step-by-step explanation:

Given  : Original population: 1,503  and New population: 1,356.

To find : Estimate the percent of decrease.

Solution : We have given

Original population: 1,503

New population: 1,356.

Value decrease = original population - new population.

Decrease = 1,503    - 1,356

Decrease population =  147

Percentage in decrease = .

Percentage in decrease = .

Percentage in decrease = .

Percentage in decrease = 9.78 %

Estimate = 10 %.

Therefore,

Percentage in decrease = 10 %

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
