Answer:

A; C; 35; A; A,B,D

Step-by-step explanation:

1. GH = sqrt(4^2 + 6^2) = sqrt(52) = 2sqrt(13)

FG = sqrt (9^2 + 4^2) = sqrt97

Add them together, and multiply by 2 to get the perimeter (because JH = GH, and FG = FJ). You get A (4sqrt13 + 2sqrt97)

2. C, because that is basically saying that all the angles are right

3. The lines are equally spaced (horizontally), and parallel, making them increase by the same amount between each. This means that (8x-7) - (7x+2) = (7x+2) - (10x-1).

Simplify:

x-9 = -3x+3 -->

4x = 12,

x =3

This means that the parallel lines' lengths are 17, 23, 29. This means that they increase by 6. This makes the longest base 29 + 6 = 35

4. The sum of exterior angles is ALWAYS 360. Divide 360 by 18 to find out how many sides it has. 360/18 = 20. The answer is A.

5. A, B, D (Laws of Rhombuses)

What is the distance between points M and N?

Free_Kalibri [48]

By using <em>triangle</em> properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

<h3>How to determine the distance between two points</h3>

In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:

$\cos L = \frac{(19.6\,m)^{2}-(14.8\,m)^{2}-(21.4\,m)^{2}}{-2\cdot (14.8\,m)\cdot (21.4\,m)}$

L ≈ 62.464°

Then, we get the distance between points M and N by the law of the cosine once again:

$MN = \sqrt{(7.4\,m)^{2}+(10.7\,m)^{2}-2\cdot (7.4\,m)\cdot (10.7\,m)\cdot \cos 62.464^{\circ}}$

MN ≈ 9.8 m

By using <em>triangle</em> properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

The sum of 5 consecutive even numbers is 20

vladimir2022 [97]

Step-by-step explanation:

Let the 1st number be x

2nd number = x + 2

3rd number = x + 4

4th number = x + 6

5th number = x + 8

x + x + 2 + x + 4 + x + 6 + x + 8 = 20

5x + 20 = 20

5x = 20 - 20

5x = 0

x = 0 ÷ 5

x = 0

The 5 consecutive integers are

0, 2, 4, 6, 8

A flatbed truck is being loaded with steel girders weighing 1825 lbs each. How much will 15 of these girders weigh, combined?

saw5 [17]

I think I know how it's done!

You need to multiply 1825 by 15. You may want to show the work in this one.

1825•15 = 27,375

Thus, the truck will be loaded with 27,375 lbs of steel girders.

Hope this helps you succeed!
