Step-by-step explanation:
A circle has 360 degrees so 360/18= 20
For the 2nd question: 360/5=72
Answer:
I think this is it but you question want super clear
A = C/2r
-7(-4p+1) + 2p
-7 x -4 = 28p
-7 x 1 = -7
28p + 2p = 30p
so
30p-7
1 year = 12 months
2yrs = 24 months
F(c) =100+5(24)
= 100+120
= $220
4,500
