Answer:
Part A) Annual
Part B) Semiannual
Part C) Monthly
Part D) Daily
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
so
Part A) Annual
in this problem we have
substitute in the formula above
Part B) Semiannual
in this problem we have
substitute in the formula above
Part C) Monthly
in this problem we have
substitute in the formula above
Part D) Daily
in this problem we have
substitute in the formula above
The number of remaining problems is:
30-20 = 10 problems.
The amount of time remaining is:
40-25 = 15minutes
For the first 20 problems the time per problem is:
t1 = 25/20 = 5/4 minutes
For the remaining problems the time per problem is:
t2 = 15/10 = 3/2 minutes
Answer:
you will be able to spend about 3/2 minutes on each remaining problem
Answer:
3m -2
Step-by-step explanation:
(10m – 6) – (7m – 4)
Distribute the minus sign
(10m – 6) – 7m + 4
Combine like terms
3m -2
Area of sector = area of circle * ratio that the sector takes up
AoS = Pi*r^2 * 255/360
= Pi * 13.4^2 (255/360)
= Pi * 179.56 (0.708333333)
= Pi * 127.188333
= 399.573933
