Answer:

Step-by-step explanation:

The larger triangle is a scaled version of the smaller one since all the angles are the same. Just the sides are different.

<u>All angles are same:</u> vertical angles are the same, right angles in both triangles, the last angle in both triangles have to be the same if the other angles were the same.

The side proportions are the same.

x/2.5 = 6/7.5

solve for x:

7.5x = 15

x = 2

Find the length of the segment with endpoints of (3,2) and (-3,-6).

MakcuM [25]

The formula of the length of the segment AB:
$A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$
We have:
$A(3;\ 2)\to x_A=3;\ y_A=2\\\\B(-3;\ -6)\to x_B=-3;\ y_B=-6$
Substitute:
$|AB|=\sqrt{(-3-3)^2+(-6-2)^2}=\sqrt{(-6)^2+(-8)^2}\\\\=\sqrt{36+64}=\sqrt{100}=10$
Answer: B) 10.

Amber is 48 inches tall and her friend Lucy is 60 inches tall. In a photograph of them together, Amber is 3 inches tall. Which p

irina [24]

The answer would be the Last option (D). This because it poses the proportion of 48 in (Amber's height) / 60 in (Lucy's height) and puts it equal to the proportion of x (what is Amber's height in the photo) / 3 (what is Lucy's height in the photo. Hope this helps :)

A race track is made from two straights and two semicircles. The straights are 80m long. The race track has a total perimeter of

Dmitriy789 [7]

Answer:

76.4 m

Step-by-step explanation:

The race track has two straights and two semi circles.

Each straight is 80m

total perimeter for the straights is 80 * 2 = 160m

two semi circles which creates a full circle

perimeter of a full circle = $\pi$ d

NB : (d) is the diameter

therefore we can find the value of the diameter

400 = 160 + $\pi$ d

400- 160 = $\pi$ d

240 = $\pi$ d

d = 240/ $\pi$

d = 76.394.....

<u>d = 76.4 m</u>
