A model is going to be built of a sports car that is 132 inches long and 66 inches high. If the scale is 1:12, what will be the
taurus [48]
Scale Factor = 1:12

It means, for every in in the model, it is equivalent to 12 inches in the real.

Dimensions of the real Car = 132 * 66

So, Dimensions of the model = 132/12 * 66/12 = 11 * 5.5

In short, Your Answer would be: 11 * 5.5 cm

Hope this helps!

1. Which of the following is the x-coordinate of the solution to the system shown below?
astra-53 [7]

Answer:

x=9

Step-by-step explanation:

Using elimination method.

Add equation 1 to equation 2

x + y = 11

x - y = 7

---------------

2x + 0 = 18

Divide both sides by 2

2x = 18

---- ----

2 2

x = 9

Find the area of the trapezoid. points are (-5,-3)(4,-3)(6,-7)(-7,-7)​
Olegator [25]

Answer:

44 square units

Step-by-step explanation:

The area of a trapezoid with bases b₁ and b₂ and height h is given by the formula

A=\left(\dfrac{b_1+b_2}{2}\right)h

If you're wondering how we get this formula, check the attached illustration (remember the area of a parallelogram is its base multiplied by its height)! Moving on to our trapezoid, the pairs of points (-5,-3)(4,-3) and (6,-7)(-7,-7) form two horizontal segments, which form b₁ and b₂, and our height is the distance between the y-coordinates -3 and -7, which is 4. We can find b₁ and b₂ by finding the distance between the x coordinates in their pairs of points:

b_1=|-5-4|=|-9|=9\\b_2=|6-(-7)|=|6+7|=13

Putting it altogether:

A=\left(\dfrac{9+13}{2}\right)(4)=\left(\dfrac{22}{2}\right)(4)=(11)(4)=44

So the area of our trapezoid is 44.
