Let's take the difference between the old and new (70 - 60) to get 10 and then divide this by the old (70) amount...10/70 = .142857 convert to a percent by moving the decimal 2 spaces to the right... 14.29 %

Answer:

Diagonal=11.3m

Area of square (A) =1/2*d^2

=1/2*(11.3)^2

=63.845m^2

We know,

Area of square A= l^2

63.845=l^2

$\sqrt{63.845 }$

L=7.99m

Now,

Perimeter of square =4l

=4*7.99

=31.96m

How much interest was earned on $108,310 for 120 months if it was invested at a 4.5% simple interest

zvonat [6]

Answer:

$48,739.50

Step-by-step explanation:

You are going to want to use the simple interest formula for this.

$I = Prt$

P = principal amount

r = interest rate (decimal form)

t = time (years)

First convert 4.5% into its decimal form:

4.5% -> $\frac{4.5}{100}$ -> 0.045

Next, we need to change 120 months into years:

$\frac{120}{12} =10$

(10 years)

Now, plug in the values into the equation:

$I=108,310(0.045)(10)$

$I=48,739.50$

The interest earned after 120 months was $48,739.50
