Answer should be the second one, B
Answer:
96m
Step-by-step explanation:
12m * 8 = 96m
unless lengths are counted as to one side and back then it would be double 96
I'll do the first two to get you started
===============================================
Problem 1
A = 3 = starting value
B = 10 = ending value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (10-3)/3 ] * 100%
C = (7/3) * 100%
C = 2.3333333 * 100%
C = 233.33333%
C = 233.3%
The positive C value means we have a percent increase. If C was negative, then we'd have a percent decrease.
<h3>Answer: 233.3% increase</h3>
===============================================
Problem 2
A = 9 = start value
B = 20 = end value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (20-9)/9 ] * 100%
C = (11/9)*100%
C = 1.2222222222*100%
C = 122.22222222%
C = 122.2%
<h3>Answer: 122.2% increase</h3>
Answer:
Yes
Step-by-step explanation:
B is a subset of A because if A= {0,1,2,3,4} and B= {1,2} B is a part of A and B is a smaller version of A
Don't know if this helps but this is how I learned subsets.
