I think it is 15 hours If you wrote better I could've explained better but if that cost $5 per 5 Hour that means you spend $1 per 1 hour so if you spend $15 that mean you used bike for 15 hours
Calculus is a form of math its not a problem so there would be no formula
Answer:
2.8 years or 33.6 months.
Step-by-step explanation:
I am not sure what your questions is, but I assume it is how long it will take to pay it off?
In a year (15*12,) you would have paid $180 of it.
x = 500/180
Therefore, it will take you approximately 2.8 years to pay off your loan, excluding interest, of course, since you did not provide that rate.
One battery costs $1.44.
The unit rate would be

To get that answer, you would have to divide 13 ÷ 9.
I'm not sure if this is what you were looking for, but if it was, I hope I helped! :-)
Answer:
249.42 units²
Step-by-step explanation:
Given only the apothem of an n-sided regular polygon, the area can be computed as ...
... A = n·a²·tan(180°/n)
For n=3 and a=4√3, this is ...
... A = 3·(4√3)²·tan(60°)
... A = 3·48·√3 = 144√3 . . . . units²
... A ≈ 249.42 units²
