Answer: The length is 24.5 feet.

Step-by-step explanation:

The formula for the perimeter of a rectangle is P = 2L + 2W.

Plug in the values you know

87 = 2L + 2(19)

Solve for L

87 = 2L + 38

subtract 38 from both sides

49 = 2L

divide both sides by 2

L = 24.5

Find the value of x.

elena-s [515]

Hi there!

Using the formula - n-2*180 -, we know that the interior angles of a pentagon add up to 540. We can use the values we're given and add them together and set them all equal to 540, then solve.

WORK:
540 = 204 + 12x
336 = 12x
x = 28

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

What amount of money will accumulate to $192,400 in 6 years and 11 months at the interest rate of 5.36% compounded semi-annually

MaRussiya [10]

We will have the following:

$\begin{gathered} 192400=A(1+\frac{0.0536}{2})^{(11/12)(2)}\Rightarrow A=\frac{192400}{(1+0.0536/2)^{(11/12)(2)}} \\ \\ \Rightarrow A=183293.7505...\Rightarrow A\approx18329375 \end{gathered}$

So, the original quantity was approximately $183 293.75.
