At a sale this week, a desk is being sold for 128.80. This is a 72% discount from the original price. What is the original price

wel

Answer:

$460

Step-by-step explanation:

If the 128.80 is the price of the desk after a 72% discount, it means that 128.80 is 100-72=28% of the original price.

From here, we can divide 128.80 by 28 to find what 1% of the price is then multiply the value by 100 to find 100%, or the original price.

128.80/28 = 4.6

4.6 x 100 = 460

Original price = $460

Hope this helped!

The area of the trapezoid is 40 square units.

Whitepunk [10]

Answer:

5 units

Step-by-step explanation:

Image of the trapezoid is attached.

To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.

The formula for area of a trapezoid is:

$A = (\frac{a + b}{2}) h$

Here, a and b represents the bases of the trapezoid.

a = 6

b = 10

h which represents height is unknown.

A = 40

Substitute figures:

$40 = (\frac{6 + 10}{2}) h$

$40 = (\frac{16}{2}) h$

$40 = 8 * h$

Solve for h:

$h = \frac{40}{8}$

$h = 5$

The height of the trapezoid is 5 units
