Today only, a desk is being sold at a 33% discount. The sale price is $268. What was the price yesterday?
Serga [27]

Discount percent = 33%

Sale price = $268

Let the original price be $x.

So,

x - (33\% \: of \: x) = 268 \\  =  > x - ( \frac{33}{100}  \times x) = 268 \\  =  > x - ( \frac{33x}{100}) = 268 \\  =  >  \frac{100x}{100}  -  \frac{33x}{100}  = 268 \\  =  >  \frac{(100x - 33x)}{100}  = 268 \\  =  >  \frac{67x}{100}  = 268 \\  =  > 67x = 268 \times 100 \\  =  > 67x = 26800 \\  =  > x =  \frac{26800}{67}  \\  =  > x = 400

So, yesterday the price was $400.

Stonehenge is a circular arrangement of massive stones near Salisbury, England. A viewer at V observes the monument from a point
Marysya12 [62]

We are given the following measures:

mAB = 48°

mDC = 180°

 

In the given figure above, we can say that angle AVB is an exterior angle which intercepts two arcs, arc AB and arc DC, therefore in this case to solve for the measure of angle mAVB, we have to make use of the formula which is in words:

Find the difference between the measures of the two intercepted arcs and divide by 2, or expressed mathematically in this case as:

mAVB = (mDC – mAB) / 2

 

Substituting the given values into the equation:

mAVB = (180° - 48°) / 2

mAVB = 66°
