A sofa is on sale for 73% off. The sale price is $172.80. What is the regular price?

Lapatulllka [165]

To get the answer you have to divide the sale price $172.80 by 73%.
So first you turn 73% into a decimal by moving the decimal two places to the left turning it into .73

$172.80 divided by .73 = $236.71

You can check by then multiplying $236.71 with .73

An owner of an repair service Company eliminates that for every 30 hours a repair person is on the job he can bill for only 72%

vredina [299]

Answer: He is idle for 8.4 hours.

Step-by-step explanation:

Since we have given that

Number of hours he repairs =30 hours

Percentage of hours he worked = 72%

Remaining percentage of hours he remains idle is given by

$100-72\\\\=28\%$

So, Number of hours he is idle for a driving is given by

$0.28\times 30\\\\=8.4\ hours$

Hence, he is idle for 8.4 hours.

Using the quadratic formula, what is the solution to 2x^2-5x-6=0 ?

Alex17521 [72]

$\bf \textit{quadratic formula}\\

\begin{array}{lcclll}
2x^2&-5x&-6&=0\\
\uparrow &\uparrow &\uparrow \\
a&b&c
\end{array}
\qquad \qquad 
x= \cfrac{ - {{ b}} \pm \sqrt { {{ b}}^2 -4{{ a}}{{ c}}}}{2{{ a}}}\\\\
-----------------------------\\\\
x=\cfrac{-(-5)\pm\sqrt{(-5)^2-4(2)(-6)}}{2(2)}\implies x=\cfrac{5\pm\sqrt{25+48}}{4}
\\\\\\
x=\cfrac{5\pm\sqrt{73}}{4}\implies x=
\begin{cases}
\cfrac{5+\sqrt{73}}{4}\\\\
\cfrac{5-\sqrt{73}}{4}
\end{cases}$
