Answer:

option D. 126 cm

Step-by-step explanation:

step 1

Find the scale factor

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

In this problem

Triangles PQR and XYZ are similar by AA Similarity Theorem

$\frac{XY}{PQ}=\frac{YZ}{QR}=\frac{XZ}{PR}$

Let

z ---> the scale factor

$z=\frac{XY}{PQ}$

substitute the given values

$z=\frac{30}{5}=6$

step 2

Find the perimeter of triangle XYZ

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z ----> the scale factor

p_1 ----> the perimeter of triangle XYZ

p_2 ---> the perimeter of triangle PQR

$z=\frac{p_1}{p_2}$

The perimeter of triangle PQR is

$p_2=5+10+6=21\ cm$

we have

$z=6\\p_2=21\ cm$

substitute

$6=\frac{p_1}{21}$

$p_1=6(21)=126\ cm$

therefore

The perimeter of triangle XYZ is 126 cm

Question 4 Multiple Choice Worth 4 points)

Semmy [17]

Answer:

Question No 4

The equation will be: $y=-\frac{1}{2}x+11$

Option B is correct answer.

Question No 5

The equation will be: $y=\frac{3}{4}x+4$

Option A is correct answer.

Step-by-step explanation:

Question 4

The option equations are in slope intercept forms, so we will write equation in slope intercept form.

The general equation of slope intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

Using the point (2,10) and (4,9) we can find slope

The formula used is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Putting values and finding slope:

$Slope=\frac{9-10}{4-2}\\Slope=-\frac{1}{2}$

So, we get slope m = - 1/2

Finding y-intercept

Using point (2,10) and slope m =1/2 we can find y-intercept

$y=mx+b\\10=-\frac{1}{2}(2)+b\\10=-1+b\\b=10+1\\b=11$

So, equation will be:

$y=mx+b\\y=-\frac{1}{2}x+11$

Option B is correct answer.

Question 5

The option equations are in slope intercept forms, so we will write equation in slope intercept form.

The general equation of slope intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

Using the point (0,4) and (4,7) from the graph we can find slope

The formula used is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Putting values and finding slope:

$Slope=\frac{7-4}{4-0}\\Slope=\frac{3}{4}$

So, we get slope m = 3/4

Finding y-intercept

Using point (0.4) and slope m = 3/4 we can find y-intercept

$y=mx+b\\4=\frac{3}{4}(0)+b\\4=0+b\\b=4$

So, equation will be:

$y=mx+b\\y=\frac{3}{4}x+4$

Option A is correct answer.
