Answer:
4 h
Step-by-step explanation:
The resting spot was at the 8 mi mark.
When Stacey reached the 16th mile, they had covered
16 mi - 8 mi = 8 mi
They took 2 h for every 1 h, so

It may be easier to do this calculation on a number line. Each jump of 2 mi represents 1 h, and there are four jumps, so they took four hours.
Answer:
1260.04
Step-by-step explanation:
The formula for compound interest is:
A = P(1+
where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods elapsed. Since the deposit was compounded annually, just like the interest, we can omit the n in the equation.
Applying the formula to question:
800(1+
= 1260.04 (rounded off to nearest cent since it's money)
D becuase if you square root 11 you get an irrational number try putting it in the calculator and you would get a crazy number
Answer:21v/22
Step-by-step explanation:
Circumference of a circle=2×π×radius
6v=2×22/7×r
7×6v=2×22×r
42v=44r
Radius=42v/44
Radius=21v/22
