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.

A rectangular piece of stained glass has the dimensions shown in the diagram. What is the probability that a random leaf that la

weeeeeb [17]

Answer:

The correct option is D) $\frac{2}{3}$

Step-by-step explanation:

Consider the provided figure.

We need to find the probability that a random leaf that lands on the rectangle lands within the section shaped like a trapezoid.

For this first find the total area as shown:

The given figure is a rectangle.

The area of rectangle is $l\times b$

Where, l = 6 cm + 3 cm = 9 cm and b = 5cm

Therefore the area of the rectangle is;

Area of rectangle = $9cm\times 5cm=45cm$

Now find the area of trapezoid.

The area of trapezoid is: $\frac{a+b}{2}h$

Where h is the height and a and b are the parallel sides.

Area of trapezoid = $\frac{9+3}{2}\times 5=30$

Thus, the area of trapezoid is 30 cm.

Therefore, the probability that a random leaf that lands on the rectangle lands within the section shaped like a trapezoid is:

$Probability=\frac{\text{Area of trapezoid}}{\text{Area of rectangle}}$

$Probability=\frac{30}{45}=\frac{2}{3}$

Hence, the correct option is D) $\frac{2}{3}$
