In the diagrams below, ABC is similar to RST. Use a proportion with sides AB and RS to find the scale factor of ABC to RST. Show
kicyunya [14]

Answer:

The scale factor of triangle ABC to triangle RST is 1/3

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z ----> the scale factor

To find the scale factor divide the length side of the image (reduced triangle) by the corresponding length side of the pre-image (original triangle)

z=\frac{RS}{AB}

substitute the values

z=\frac{6}{18}

simplify

z=\frac{1}{3}

The scale factor is less than 1

so

Is a reduction

A 32-ft pipe must be cut into three pieces. The longest piece will be twice as long as the shortest piece, and the medium-sized
True [87]

Answer:

7, 11, 14 feet from shortest to longest

Step-by-step explanation:

Let's say that the shortest pipe is equal to x, and work from there.

The medium size piece is 4 feet longer than the shortest piece, so it is equal to 4+x

The longest piece is twice as long as the shortest piece, so it is equal to 2 * x.

The three pieces added up make up the 32 feet pipe, so we can write this as

(2*x) + (4+x) + x = 32

2*x + 4 + x + x = 32

4 * x + 4 = 32

subtract 4 from both sides to isolate the x and its coefficient

4 * x = 28

divide both sides by 4 to isolate the x

x= 7

Therefore, the shortest piece is x=7 feet long. The medium piece is x+4=11 feet long, and the longest piece is x*2=14 feet long
