Find the perimeter of a rectangle of A=2.76x10^12cm^2 and one side is 4.6x10^5

levacccp [35]

Answer:

1.292 x 10^7 cm^2

Step-by-step explanation:

Since the area of a rectangle is A = L x W and you are given the area and one side, you can rearrange this equation to solve for the other:

$L=\frac{A}{W}\\L=\frac{2.76 \times 10^{12}}{4.6 \times 10^5}\\L = 6 \times 10^6$

Therefore the length of the other side is 6 x 10^6.

The perimeter of a rectangle is P = 2L + 2W. We can solve that now that we have the length of the sides:

$P = 2(6 \times 10^6) + 2(4.6 \times 10^5)\\P = 1.292 \times 10^7$

Monica took out a 30-year loan for $130,000 at an APR of 8.4%, compounded monthly, and she is making monthly payments of $990.39

Over [174]

Answer: $ 40331.781 (Approx)

Step-by-step explanation:

Let Monica pay off $ x in 12 years,

Thus, for 12 years, his present value, PV = $ x

Given, APR of the loan = 8.4% = 0.084

Thus, the monthly rate of the loan, r = 0.084/12 = 0.007

The number of period in 12 years, n = 144

And, the monthly payment, P = $ 990.39

Thus, by the formula,

$\frac{r(PV)}{1-(1+r)^{-n}}=P$

$\frac{0.007 x}{1-(1+0.007)^{-144}} = 990.39$

$\frac{0.007 x}{1-0.36623195919}=990.39$

$\frac{0.007 x}{0.6337680408 } = 990.39$

$0.007 x=990.39\times 0.6337680408$

$0.007 x=627.677529937$

$x=89668.2185624$

Thus, He pay off $ 89668.2185624 of the original amount of the loan.

⇒The amount of loan left after 12 years

= 130,000 - 89668.2185624

=40331.7814376 ≈ $ 40331.781
