Answer:
3hours and 12.5 minutes
Step-by-step explanation:
45/6=7.5x25=187.5/60=3hours and 12.5 minutes
Answer:
The total number of hours = 35 hours.
Step-by-step explanation:
The annual fee of Calm Spa = $125
Per hour charge of Calm Spa = $10
Annual fee of Relax Spa = $230
Per hour charge of Relax Spa = $7
Now we have to find the number of hours for which both have same cost.
Let the number of hours = x
Thus, 125 + 10x = 230 + 7x
10x-7x = 230 – 125
3x = 105
x = 35
The total number of hours = 35 hours.
Solution :
Given :
Principal amount deposited, P = $ 6000
Rate of interest, r = 5%
Number of years, t = 4 years
When the deposited amount is compounded semiannually, i.e. n = 2
Therefore,
Future value,



= 6000 x 1.2184
= 7310.4
Therefore, after 4 years there will be $ 7310.4 in the amount when compounded semi annually.
When the deposited amount is compounded quarterly, i.e. n = 4
Therefore,
Future value,



= 6000 x 1.219889
= 7319.334
Therefore, after 4 years there will be $ 7319.334 in the amount when compounded quarterly.
When the deposited amount is compounded monthly, i.e. n = 12
Therefore,
Future value,



= 6000 x 1.22089
= 7325.34
Therefore, after 4 years there will be $ 7325.34 in the amount when compounded monthly.
