The area of a trapezoid is 60 square inches. One of the bases is 8 inches long. The height is 6 inches long. What is the length
Mashcka [7]

Answer:

12 in

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h(b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases

Given h = 6, b₁ = 8 and A = 60 , then

\frac{1}{2} × 6 × (8 + b₂ ) = 60 , that is

3(8 + b₂ ) = 60 ( divide both sides by 3 )

8 + b₂ = 20 ( subtract 8 from both sides )

b₂ = 12

The length of the second base is 12 inches

Help me !!!! ASAP !!
Anastasy [175]

The answer is C.

If you multiply the top equation by 3 the x variable would become 2x * 3 = 6x

Multiplying the second equation by 2 the x variable becomes -3x * 2 = -6x

You would then have 6x - 6x, which would eliminate the x variable.

Calculate mpg for w=1000,w=2000;calculate weight when mpg=30
Setler79 [48]

Based on the information above, the car with 1,000 pounds more will only go 1,194 miles, and the one with 2,000 pounds more will only go 1,188 miles.

<h3>What does MPG stand for?</h3>

MPG stands for miles per gallon, and refers to the distance in miles a vehicle travels for each gallon of fuel in its tank.

In general, a car consumes about 1,200 miles per gallon. However, when you add load to it, its fuel consumption is higher because it requires more force to move.

Additionally, some studies state that for every 1,000 pounds of weight added to the car, it will yield 0.5% less. So if the car has 1,000 more pounds, it's not going to go 1,200 miles per gallon, it's going to go 1,194 miles.

On the other hand, if 2,000 pounds of weight were added, the fuel economy would be 1% less, that is, it would travel 1,188 miles per gallon.
