Multiply the divisor by as many 10's as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10's
Time = 3 miles / (20 mph - wind velocity)
time = 2 miles / (20 mph + wind velocity)
3 miles / (20 mph + wind velocity) = 2 miles / (20 mph - wind velocity)
3/2 = (20 mph + wind velocity) / (20 mph - wind velocity)
1.5 = (20 mph + wv) / (20 mph -wv)
30 mph -1.5wv = 20 mph -wv
10 mph = 2.5 wv
wind velocity = 4 mph

y 65 degrees, because abc-dce
Step-by-step explanation:
Answer:
Step-by-step explanation: First figure what’s in the parentheses. (3-2*2) wanna do 2*2 That’s 4 then (3-4) = -1. 2+(-1)*1. Then multiply -1 by 1 which is -1. Then 2+(-1)= 1
Answer:
3.1in
Step-by-step explanation:
Radius: r=2in
Perimeter of circle: p=2×pi×r=4×pi
Perimeter of figure: p1=p/4=pi=3.14in
Best approximation: 3.1in
