Answer:
YES
Step-by-step explanation:
COZ I SEE
525/1000 = 105/200 = 21/40
13a) y = 0.45x
13b) 52 * 0.45 = 23.4
13c) I will let u figure this one out
Answer:
regular polygon of 9 sides has 9 lines of symmetry
30 + 5h = 20h
30 = 20h - 5h
30 = 15h
30/15 = h
2 = h
at 2 hrs, they both charge the same rate...
30 + 5(2) = 30 + 10 = 40
20h = 20(2) = 40
so at 2 hrs, they both charge $ 40
