3430 divided by 70 would give us 49. So 49 yards is how long the width of the field is.
Simple interest:
Final value = principle (starting balance) x interest x time in years
Fv = PiN
18,000 x 0.045 x 3 = $2430
2430 + 18000 = $20430
Circumference (of a circle)
You find a circumference by this:
C- circumference
= - equals
2-2
π- pi
R- radius
Hope this helps :)
5 is our starting amount. 40 divided by 20 equals 2. This means that you started with 5 and have 2 left , 5-2=3 :) you used 3 twenties hope this helped you out
