Find the missing side of the triangle.
katovenus [111]

15^2 = x^2 + 11^2

225 = x^2 + 121

Subtract both sides 121

225 - 121 = x^2 + 121 - 121

104 = x^2

x = √104

x = √4 × 26

x = √4 × √26

x = 2 × √26

x = 2 √26

If the purchase price for a house is $309,900, what is the monthly payment if you put 20% down for a 30 year loan with a fixed r
Nookie1986 [14]

Answer:

$1486.41.

Step-by-step explanation:

Purchase price = $309,900

Down payment percent = 20 %

Remaining amount Percentage  = 100-20 = 80%

Mortgage amount = 309900 \times 0.80

                              =247920

Formula of monthly payment : P =\frac{\frac{rM}{1 -(1 +\frac{r}{n})^-{nt}}}{n}

where P = the payment,

r = the annual rate =6% = 0.06

M = the mortgage amount = $247920

t = the number of years=30

n = the number of payments per year= 12

Substitute the values.

P =\frac{\frac{0.06 \times 247920}{1 -(1 +\frac{0.06}{12})^-{12\times 30}}}{12}

P=1486.40566196

Hence the monthly payment is $1486.41.

Thus Option C is correct.
