Answer:14%
Step-by-step explanation:
final grade score=a
20% of a=15
20/100 x a=15
20a/100=15
Cross multiply
20a=15 x 100
20a=1500
Divide both sides by 20
20a/20=1500/20
a=75
B% of 75=10.5
B/100 x 75=10.5
75B/100=10.5
75B=10.5 x 100
75B=1050
Divide both sides by 75
75B/75=1050/75
B=14
Answer:
.18
77 x .24% (0.0024) = .1848
Round to the nearest hundredth...
.18!
A = (pi)r^2
diameter = 12 in
radius = d/2 = 6 in
A = (pi)6^2
A = 36(pi)
