Answer:
Percentage change in interest groups between 1959 (500) & 1995 (600) = 20%
Step-by-step explanation:
Percentage change = <u>Change ie (New - Old) </u> x 100
Old value
Suppose -
Number of interest groups in 1959 = 500
Number of interest groups in 1995 = 600
Percentage change = [ (600 - 500) / 500 ] x 100
( 100 / 500 ) x 100 = 20%
Your formula here is A=pir^2
Plug in the numbers but instead use 22/7 for pi
A=(22/7)(21)^2
A=22/7*441=1386
Answer is 1386 sq inches
Answer:
16/5 or 3.2
Step-by-step explanation:
4cm/5km = x/4km
Cross multiply to find answer
Yes -14 is greater than -17
5(x+4)=4(x-6)
5x+5•4=4x-4•6
5x+20=4x-24
x= -44
