The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 and 5.6 feet. What is the height of the trapezoid

olasank [31]

Answer:

The height is 8.3 feet

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

Area=½(sum of bases)*height

We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.

$70.55 = \frac{1}{2} (11.4 + 5.6)h$

$70.55 = \frac{1}{2} (17)h$

$70 .55 = 8.5h$

$h = \frac{70.55}{8.5}$

$h = 8.3$

Susan tips at the rate of $65 to 5 waiters. If she can afford a $90 tip, then she would be tipping 7 waiters? Explain your reaso

Alexeev081 [22]

No she would not be tipping 7 waiters. This is because for every waiter she tips $13.00 shown by 65/5=13. If she wanted to tip 7 waiters at the same rate she would need $91.00 shown by 7*13=91.00.
