3:6 ratio is 1:2
9:24 ratio is 3:8
It equals 4/3 or 1.3333333...
To add fractions, you want the bottom number (the denominator) to be the same.
The 1/3 has a denominator of 3, so to make 1 have a denominator of 3, you can make 1=3/3
so you have 3/3 +1/3=4/3
9.6 x 10^-2 / 9.5 * 10^-5 = 1 * 10^(-2-(-5) = 1 * 10^3
so the blanks are 1000 and greater
First we need to calculate the monthly payment to repay the loan using the formula of the present value of an annuity ordinary which is
Pv=pmt [(1-(1+r/k)^(-n))÷(r/k)]
PV the amount of the loan 4250
PMT monthly payment?
R interest rate 0.1325
K compounded monthly 12
N time 24 months
Solve the formula for PMT to get
PMT=pv÷ [(1-(1+r/k)^(-n))÷(r/k)]
PMT=4,250÷((1−(1+0.1325÷12)^(−24))÷(0.1325÷12))=202.55
Now to find the total finance charge use the formula of
Total finance charge=monthly payment×number of months-the amount of the loan
Total finance charge=
202.55×24−4,250=611.2
So the answer is 611.2
Hope it helps!
now onto the second one,
now, the extraneous part, I don't see either as extraneous, 3 and 12 do work, however, I take it is referring to the root, so if we nevermind the root has ± versions, and say only assuming the value coming from the root is say positive, then
