Convert the rational number to decimals, then solve it as a decimal instead, (with the optional choice of re-converting it back to rational).

PLEASE HELP!! I need this completed ASAP but I don't understand any of it!! It's due very soon!
lidiya [134]

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.

____ [38]

Answer:

b. 75

Step-by-step explanation:

a(n) = a1 + d(n-1)

a(n) = 8.5 + 3.5(n - 1)

a(20) =  8.5 + 3.5(20 - 1)

a(20) =  8.5 + 3.5(19)

a(20) = 8.5  + 66.5

a(20) = 75

8(3a+5)???? please help!!!!!! ASAP!!!!
r-ruslan [8.4K]

I'm assuming your teacher wants you to distribute. If so, then you multiply the outer term 8 by each term inside (3a and 5). After that you add.

8 times 3a = 24a

8 times 5 = 40

So 8(3a+5) becomes 24a+40

We do not combine 24a and 40 as they are not like terms. So we leave 24a+40 as it is.
