1. 16/30 or 8/15 ( SIMPLIFIED) because there are 30 pieces.
Four 15 inches + Ten 12 inches = 14
30-14 = 16
So there are 16 8 inch pieces
3. A. 7/20 because 7 pennies ( what you want ) over 20 coins ( 13 dimes + 7 pennies)
B. 13/20
4. Not sure but I think it's 0.75 ( 1.00 - 0.25 )
And 0.05 ( 1.00- 0.95 )
Take 225(pi) * 45/360 = 28.125(pi) in ^2
the 45 is the measure of the central angle and 360 is the total degrees in a circle
N = 3 because you have to cross-multiply.
