The top of a desk is shaped like a trapezoid. The bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk

Stolb23 [73]

Answer:

28 centimeters.

Step-by-step explanation:

Let w be width of desk.

We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.

Since the area of trapezoid is half the sum of parallel sides times its height.

$\text{Area of trapezoid}=\frac{h}{2}*(a+b)$ , where

h= Height of trapezoid,

a and b= Length of parallel sides of trapezoid.

We have been given that the height of the trapezoid is the width of the desk.

Upon substituting our given vales in above formula we will get,

$791=\frac{w}{2}*(26.5+30)$

$791=\frac{w}{2}*(56.5)$

$791=w*28.25$

$w=\frac{791}{28.25}$

$w=28$

Therefore, the width of trapezoid is 28 centimeters.

Alicia took a friend to dinner for her birthday. The total bill for dinner was $30.69 (including tax and a tip). If Alicia paid

tigry1 [53]

Answer:

The original bill was $25.26

Step-by-step explanation:

To find the original bill, you need to divide the amount paid by the percentage paid. Since the tip was 21.5% on top of the full amount already, we know she paid 121.5%. So we can divide the cost by that.

$30.69/121.5% = $25.26
