8 0

Answer:

There are 80 men on the train.

Step-by-step explanation:

M : W

4  : 5

W : C

10 : 9

As you can see, the units for women is not equal, so I shall multiply the first ratio by 2 so that the units for women is 10.

M : W

8  : 10

Now that everything has the same units, I can put the ratio of men, women and children together:

M : W : C

8  : 10 : 9

Total number of units = 8 + 10 + 9

                                    = 27

27 units = 270

No. of men (8 units) = \frac{8}{27} × 270

                                 = 80

Find the coordinates of the third vertex that completes the construction of a right triangle on the coordinate plane.
Neko [114]

Answer:

<u>(7,a) Where a ∈ R - {7}</u>

<u>OR</u>

<u>(-2,a) where a ∈ R - {-2}</u>

Step-by-step explanation:

The coordinates of the given line from the right to the left are:

(7,1) and (-2,1)

So, to make a right triangle, we need to make a right angle or by another words, we need to a make a perpendicular line to the given line (i.e: a vertical line parallel to the y-axis at one of the given points)

So, the third vertex must be on the line x=7 or x=-2

So, the coordinates of the third vertex is:

<u>(7,a) Where a ∈ R - {7}</u>

<u>OR</u>

<u>(-2,a) where a ∈ R - {-2}</u>
