a radio commercial for a loan company states: "you only pay for each $500 borrowed." If you borrow $1959 for 251 days, what amou
Natasha2012 [34]
Well... hmmm so.. for 500 bucks you only pay a rate of say "r", and it comes down to only 28cents, or $0.28.

If 500 is say the 100%, what percentage is 0.28?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
500&100\\
0.28&p
\end{array}\implies \cfrac{500}{0.28}=\cfrac{100}{p}\implies p=\cfrac{0.28\cdot 100}{500}
\\\\\\
p=0.056\%\implies p=\cfrac{56}{1000}\%

now, we're assuming the company is charging and APR, so you pay that at the end of the year.  We're also assuming the year is only 360 days.

so, if you borrow 1959 on simple interest for 251 days out of 360 days, how much are you repaying?

\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$1959\\
r=rate\to 0.056\%\to \frac{0.056}{100}\to &0.00056\\
t=years\to &\frac{251}{360} 
\end{cases}
\\\\\\
A=1959\left(1+0.00056\cdot  \frac{251}{360}  \right)

and surely you can do that one... which is just 1959 and a few pennies.

To find the area of the shape which is the shaded area I assume: we must find the sum of the area of the rectangle AECD and triangle BEC

   Total Area =area of rectangle AECD + triangle BEC

                     = 9 * 15 +  (1/2) * 6 * 15 = 136 + 45 = 181 square milimeters

Place the following steps in order to describe how to solve the following equation: ​ ​ 2(2x+3)-2=5
ivolga24 [154]

Answer:

0.25

Step-by-step explanation:

First, you distribute the equation.

2(2x+3)-2=5

4x+6-2=5

Then, you combine like terms.

4x+6-2=5

4x+4=5

Next, you subtract 4 from each side.

4x+4=5

4x+4-4=4x

5-4=1

4x=1

Finally, you divide each side by 4.

4x/4

1/4

(4x/4 you'd end up with x)

Answer: x=1/4

To the nearest hundredth of a percent, what is the percent of change from 2007 to 2013?
Sati [7]

Answer:99.70

Step-by-step explanation:

X/100×2013=2007

2013x=2007×100

2013x=200700

Divide both sides by 2013

X=200700/2013

X=99.70
