Step-by-step explanation:
Charges per page = $0.08
Amount Lionel paid = $20.00
No of pages = 20 ÷ 0.08 = 250 pages
This question is incomplete but if you are asking for the angle measure then sin (10) is 0.1736481777

where A=final amount
P=principal
r=rate in decimal form
t=time in years
we are given that P=500, r=12%=0.12
we want to find A when t=10, 20, and 30
so


when t=10, 
when t=20, 
when t=30, 
4,4,4,5,5,5,6,6,7,8,8,8,9,10,10,10,10
It is the number 7.
