A trapezoid has an area of 150 square meters. If the bases are 14 meters and 16 meters, what us the height of the trapezoid?

goldenfox [79]

To find the area of a trapezoid, we use the following formula:
$a = \frac{1}{2} (b1 + b2) \times h$
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.

So, we have got the following information
$a = 150$
$b1 = 14$
$b2 = 16$

Filling in the formula gives us:
$150 = \frac{{1} }{2} \times (14 + 16) \times h$
$150 = \frac{1}{2} \times 30 \times h$
$150 = 15 \times h$
Finally we have to divide both sides by 15.
$h = 150 \div 15 = 10$
Therefore, the height of the trapezoid is 10 meters.

Cho had $2.85 in nickels and $3.40 in dimes. Then she gave an equal number of her nickels and dimes to her brother. Now Cho has

Marina86 [1]

285-5x=340-10x

285-5x-(340-10x)=0

-5x-(-10x+340)+285=0

-5x+10x-340+285=0

5x-55=0

5x=55

x=55/5

x=11

The weekly salary Y of an individual is proportional to the number of hours X worked. A person who works 40 hours is paid 900$.

Simora [160]

Answer:

y = 22.5x

worked 28 hours

Step-by-step explanation:

First find out what they make in 1 hour (rather than 40)

you can do this by 900 / 40 which gives you 22.5

this means for every hour worked, they get $22.50

so you can make the equation of y = 22.5x

try finding the hours worked by division

630/ 22.5 = 28

plug 28 into your equation to check

y = 22.5 ( 28 )

y = $630

hope this helps
