What is mortgage of a 400000.00 loan at 6% 30 year fixed
Ivahew [28]

9514 1404 393

Answer:

  $2398.20

Step-by-step explanation:

Perhaps you want the monthly payment. It is given by the amortization formula ...

  A = P(r/n)/(1 -(1 +r/n)^(-nt))

where P is the principal amount, r is the annual interest rate, n is the number of payments per year, t is the number of years.

Your monthly payment will use P = 400,000; r = 0.06, n = 12, t = 30.

  A = $400,000(0.06/12)/(1 -(1 +0.06/12)^(-12·30)) ≈ $2398.20

motikmotik

Answer: D)  \dfrac{189}{8}\ cm^3

The volume of a rectangular prism is given by :_

\text{Volume}=\text{length*width*height}

Given: Length of the rectangular prism = \dfrac{9}{2}\ cm

Width =  \dfrac{7}{2}\ cm

Height =  \dfrac{3{2}\ cm

Then, the volume of a rectangular prism will be :-

\text{Volume}\dfrac{9}{2}\times\dfrac{7}{2}\times\dfrac{3}{2}\\\\\Rightarrow\text{Volume}=\dfrac{189}{8}\ cm^3
