Ratio = 5:2:3:8
Sum of all internal angles = 360°
5x + 2x + 3x + 8x = 360°
18x = 360°
x = 20°
Therefore,
5x = 100°
2x = 40°
3x = 60°
8x = 160°
5:2:3:8 :: 100:40:60:160.

An amount of $23,000 is borrowed for 11 years at 6.75% interest, compounded annually. If the loan is paid in full at the end of

Pavel [41]

Answer:

Given that,

An amount of $23,000 is borrowed for 11 years at 6.75% interest, compounded annually.

To find the Amount paid back after 11 years.

Explanation:

we know that,

The formula to find the,

Amount after n years of interest rate r% compounded annually is,

$A=P(1+\frac{r}{100})^n$

where P is the initial amount.

Here, we have that,

P=$23,000

r=6.75

n=11

Substitute the values we get,

$A=23000(1+\frac{6.75}{100})^{11}$

Solving this we get,

$A=23000(1+0.0675)^{11}$ $A=23000(1.0675)^{11}$ $A=23000(2.05138)$ $A=47181.805$

Round to the nearest dollar.

$A=47181.805\approx47182$

Answer is: Amount paid back is $47182 after 11 years

4/5x=56 Please help, and explain how you got it

Scrat [10]

To solve this, we must isolate x (have it by itself).

4/5x = 56

Multiply each side by 5x.

4/5x(5x) = 56(5x)

Divide each side by 280.

4/280 = 280x/280

Solve.

0.014 = x

0.014 can also be written as 1/70
