Triangle ABC is graphed on a coordinate plane with vertices at A(-3, 7), B(9,-8), and C(-5, -6). If triangle ABC is dilated
by a scale factor of 2 with the origin as the center of dilation to create A'B'C', what will be the coordinates of the dilated
vertex of B'?

Answers

Answer:

  B' = (18, -16)

Step-by-step explanation:

Dilating means to stretch or shrink a figure. The scale factor tells us how much we are stretching or shrinking. The scale factor is 2, so the coordinates are multiplied by 2.

The ratio of teachers to students at Priory School is 2:27


What is school's total population if there are 42 staff

Answers

Answer:

609

Step-by-step explanation:

ratio of teachers to students at Priory School =2:27

Let X= total number of both the students and the teacher

Ratio of teacher=( 2/29)X

Ratio of student is (27/29 )X

But total number of teacher = 42

2/29 ×X =42

2X= 42×29

2X=1218

X= 609

Hence, school's total population is 609

The measure of angle PST 129 degrees after applying the properties of the triangle.

What is the triangle?

In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

It is given that:

The triangle is shown in the picture.

The equation can be made:

5x - 9 = (180 - (11x - 3))

5x + 11x = 180 + 3 + 9

16x = 192

x = 192/16 = 12

The measure of angle PST = 11x - 3

= 11(12) - 3

= 129 degrees

Thus, the measure of angle PST is 129 degrees after applying the properties of the triangle.

5) 42/110 or 21/55

Step-by-step explanation:

4) there are two red options out of a total of 6 options, so 2/6

5) 7 red out of total of 11, so 7/11 · 6/10 = 42/110

To get the fraction 6/10:

we reduce 7 to 6 because there is one less red than originally

we reduce 11 to 10 because there is one less from the initial total
