There are 87 girls and 58 boys!

i divided 5 from 145 and got 29.
i multiplied 29 and 3 and got 87.
87 is the girls total.
then subtracted 87 from 145 and got 58.
58 is the boys total.

hope this helps!

Answer:

<h2>You Can do this in two ways. I will shaw both, the first one is more common and more easy :</h2>

Method 1:

3/5 of 145 = girls

boys = girls - boys or 2/5

3/5 x 145 = 87

girls = 87

boys = 145-87 = 58

Method 2:

3/5 of 145 = girls

boys = girls - boys or 2/5

3/5 x 145 = 87

girls = 87

2/5 x 145 = 58

boys = 58

<h2>Thank You</h2>

Davis is buying a new car for $21,349.00.He plans to make a down payment of $3,000.00.If he's to make monthly payments of $352 f

nekit [7.7K]

He actually borrowed P=21349-3000=18349 (present value)
Assume the monthly interest is i.
then future value due to loan:
F1=P(1+i)^n=18349(1+i)^(5*12)=18349(1+i)^60
future value from monthly payment of A=352
F2=A((1+i)^n-1)/i=352((1+i)^60-1)/i
Since F1=F2 for the same loan, we have
18349(1+i)^60=352((1+i)^60-1)/i
Simplify notation by defining R=1+i, then
18349(R^60)-352(R^60-1)/(R-1)=0
Simplify further by multiplication by (R-1)
f(R)=18349*R^60*(R-1)-352(R^60-1)=0
Solve for R by trial and error, or by iteration to get R=1.004732
The APR is therefore
12*(1.004732-1)=0.056784, or 5.678% approx.

Could someone PLEASE just HELP me with this question.

agasfer [191]

<u>Answer</u>

$\frac{7}{37}$

<u>Detailed Explanation </u>

To simply answer this, since .189 has three digits we are going to be inserting 999 as the denominator since it is a repeating decimal.

$\frac{189}{999}$

We could simplify the answer!

$\frac{189}{999}$

Therefore, the answer would simply be $\frac{7}{37}$

$\frac{7}{37}$

<u>Always Remember </u>

In the future, always remember whenever you have a three digit decimal and the problem asks you to convert it into a fraction, you should always insert 1000 as the denominator (the numerator is basically the decimal without the decimal point) and simplify if necessary.
