Answer: 122.5
======================================================
Explanation:
First thing to do is to find the perimeter of figure B. Add up all the sides and we get: 5+9+9+12 = 14+21 = 35.
The scale factor 7:2 means that if the perimeter of figure A was 7, then the perimeter of figure B would be 2. Or it could be 14 for A and 4 for B. And so on. The idea is that the two perimeters scale up or down together. This allows us to set up the proportion below in which we can solve for x
(perimeter of A)/(perimeter of B) = 7/2
x/35 = 7/2
x*2 = 35*7 .... cross multiply
2x = 245
2x/2 = 245/2 .... divide both sides by 2
x = 122.5
The perimeter of figure A is 122.5
Answer:
Interest earned: $150.85
Total amount: $850.86
Step-by-step explanation:
Y=700(1.05)^4
Put the right side of the equation into a calculator and get
850.85 that's your total, so to get the amount earned subtract the original 700 from it and get 150.85
Your question evokes several thoughts. Here are two of them:. 1). It takes 3 points not all on the same line to define a plane. 2). Two points ALWAYS lie on the same line.
The greatest common divisor of 9 and 14 is 1
It is a fraction.
For example : 50/100 ... 50 is a part on 100.
100 in decimal term would be 1.00
.85 is LESS than 1.00 causing it to be a part/ or portion of 100.
