Answer: I tried to use the step by step explanation of your exercise, I hope Otis helping you and have a nice rest of your day :)
12m^2/h》cm^2/min
12m^2/h × 1 h/60 min=.2m^2/min
.2m^2/min × 10000cm^2/1 m^2=2000 cm^2/min
2000cm^2/min
30. Given problem : You deposited 2 000 dollars, then you will earn 6% simple interest.
Question: How long will it become 2 600 dollars.
Well, you didn’t mention if it’s an annual interest or monthly interest.
But let’s say that it’s a monthly interest, then let’s start solving:
=> 2000 Is the original amount + 6% interest
first month = 2000 * .06 = 120
=> 2000 + 120 = 2120
2nd month = 2120 *.06 = 127.2
=> 2120 + 127.2 = 2247.2
3rd month = 2247.2 *.06 = 134.832
=> 2247.2 + 134.832 = 2382.032
4th month = 2382.032 * .06 = 142.92192
=> 2382.032 + 142.92192 = 2524.95392
5th month = 2524.95392 * .06 = 151.497
=> 2524.95392 + 151.497 = 2676.45
Thus, on the fifth month she will earn this amount.
Answer:
Step-by-step explanation:
a) you know interest is 22 and principal is 1000 and number of months is 1
b) I = rPm
r = I/Pm
c) r = 22 / 1000(1) = 0.022 /month or 2.2% per month
or 12(0.022) = 0.264 or 26.4 % per year.
d) interest is $15, loan period is 2 weeks which occurs once during the loan, interest rate is 10% per two weeks.
P = I/rm
e) P = 15 / 0.10 = $150
Notice that there are 52 weeks/yr / 2week loan period = 26 period in a year.
This means that the APR is 0.10(26) = 2.60 or 260% annual interest rate. Pretty good return on investment if you are the lender and can keep your money lent out. Not so good if you are the borrower.
