A family is purchasing a house and needs to finance a 195,000 mortgage from the bank with an annual percentage rate (APR) of 5.3
maksim [4K]

Calculate the monthly payment:

195,000 x ( (0.05/12)x1+0.053)^12)/(1+0.053)^12-1)

Monthly payment = 1,082.84

Multiply monthly payment by 12 to get one year: 1082.84x 12 = 12994.08

Now multiply by 30 years:

12994.08 x 30 = 389822.40

The answer is $389,822

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet? Use 3.14 for π.
AysviL [449]

Answer:

14130 ft^3

Step-by-step explanation:

The formula for the volume of a cone of radius r and height h is

V = (1/3)*pi*r^2*h.

Here, V = (1/3)(3.14)(15 ft)^2*(60 ft) = 20*3.14*225 ft^3 = 14130 ft^3

68 miles to 42.5 miles
Thepotemich [5.8K]
1) subtract 42.5 miles from 68 miles to find the gross change in distance:  It is 25.5.  Since this is a decrease, write -25.5 miles.
2) divide -25.5 miles by the original distance, 68 miles:
     -0.375
3) multiply this by 100% to find the percentage decrease:
     -37.5% (answer)

What is 21 1/4% expressed as a fraction?
Neporo4naja [7]

Answer:

\frac{17}{80}

Step-by-step explanation:

we have

21\frac{1}{4}\%

Convert mixed number to an improper fraction

21\frac{1}{4}=21+\frac{1}{4}=\frac{21*4+1}{4}=\frac{85}{4}

so

21\frac{1}{4}\%=\frac{85}{4}\%

Convert percent number as a fraction

\frac{85}{4}\%=\frac{85}{4}:100=\frac{85}{4*100}=\frac{85}{400}

Simplify

Divide by 5 both numerator and denominator

\frac{17}{80}
