Answer:
percent decrease
26%
Step-by-step explanation:
Yesterday you ran 5 miles
Today you ran 3.7 miles
The amount went down, so the percent decreased
The percent decrease = (original - new)/original * 100 %
= (5-3.7)/5 * 100%
= 1.3/5 * 100 %
=.26 *100%
= 26%
To find it directly
A = 2 pi r h
A is proportional to rh
factor 2
A is multiplied by 2 * 2 = 4
factor 3
3 * 3 =9
factor 5
5 * 5 = 25
factor 10
10 * 10 = 100
(b) the increase in A by factor x is x^2
c(20)^2 = 400
Answer:
Width x height x length
Step-by-step explanation:
You just multiply the width times the height times the length.
490 x 2/5 = 980/5 = 196 girls at Garland

Bowood has more girls:
675-196 = 479 more
