so the difference is 300 - 230 = 70.

now, if we take 230 to be the 100%, what is 70 off of in percentage?

\bf \hspace{34em}|\\\\ \begin{array}{ccll} amount&\%\\ \cline{1-2} 230&100\\ 70&x \end{array}\implies \cfrac{230}{70}=\cfrac{100}{x}\implies \cfrac{23}{7}=\cfrac{100}{x} \\\\\\ 23x=700\implies x=\cfrac{700}{23}\implies x\approx 30.43

Answer:23%

Step-by-step explanation:

300-230=70

70/300=0.23(3 goes on forever)

So 23%

subtract the original with the decreased value, then divide the answer you get with 300. That should equal 0.23 or 23%

What is the answer to 5/7 + 1/4
Kobotan [32]
Let's look at the two denominators:
7= 7
4= 4
LCM(7,4)= 4*7= 28

5/7+ 1/4
= (5*4)/ (7*4)+ (1*7)/ (4*7)
= 20/28+ 7/28 (common denominator is 28)
= 27/28

The final answer is 27/28~

Answer:

Yes your friend is correct.

Step-by-step explanation:

This can become very complex when trying to explain but essentially, opposite angles like angle 4 and 6 or the 103 degree and angle 2 would have the same angle measurement. Since angle 2 and 6 are on the same straight line with lines a and b being parallel, we know that that angle 2 and 6 are equal. Since we know that angle 2 and the 103 degree angle are equivalent, we can conquer that angle 6 equals 103 degrees.

Myra borrowed $1,500 at 12.5% interest for three months. How much
den301095 [7]
Now, this is for 3 months, and we're assuming, I guess it doesn't really matter, but using simple interest.

now, 3 months is not even a year, there are 12 months in 1 year, so 3 months is 3/12 years, or 1/4.

\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$1500\\
r=rate\to 12.5\%\to \frac{12.5}{100}\to &0.125\\
t=years\to \frac{3}{12}\to &\frac{1}{4}
\end{cases}
\\\\\\
I=1500\cdot 0.125\cdot \cfrac{1}{4}\implies 46.875\approx 46.88
