Mathematics
1 answer:
Dafna11 [192]3 years ago
5 0

Answer:

No. It has 2 congruent triangles, but they do not encompass the whole area.

Step-by-step explanation:

I would say no, because then it would be a rectangle, because there would be no angle on the sides.

A=1/2(b1+b2)*h

Find the regular price. Round to the nearest cent . Sales price is 56.78 percent discount is 40%
LenaWriter [7]

100\%-40\%=60\%\\60\% = \frac{60}{100}=\frac{6}{10}=\frac{3}{5}\\\\

Numerator is 3 and denominator is 5. So, we divide the sales price by 3 and we multiply by 5 to get the whole fraction, or 100%.

\frac{56.78*5}{3} \\\frac{283.9}{3} \\94.6333333333333...

Your regular price sounds recurring, so you might have made a mistake copying.

The answer for what you've got is 94.633333...
