plz mark brainliest

Answer 2

To map the dilated image back  onto the original figure, the scale factor needed is 7.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a factor.

If a figure is dilated from the origin by a scale factor of one seventh, it is given by:

(x, y) ⇒ [(1/7)x, (1/7)y]

To map the dilated image back  onto the original figure, the scale factor needed is 7. Hence:

[(1/7)x, (1/7)y] ⇒ (x, y)

Answer:

85°

Step-by-step explanation:

Line segment AB || line m

Therefore, BC is transversal.

[tex] \therefore m\angle ABC + (m\angle ACB +m\angle A D) = 180\degree[/tex]

[tex] \therefore m\angle ABC + (55\degree + 40\degree) = 180\degree[/tex]

[tex] \therefore m\angle ABC + 95\degree = 180\degree[/tex]

[tex] \therefore m\angle ABC = 180\degree -95\degree [/tex]

[tex] \therefore m\angle ABC = 85\degree [/tex]

Answers

Step-by-step explanation:

6x²–5x–4 = 0

6×4 = 24..

write many ways 24 can be written..

24 = (6×4), (1×24), (12×2), (8×3)

(8×3) --> –8+3 = –5

6x²+3x–8x–4 = 0

6x(x+½)–8(x+½) = 0

(6x–8)(x+½) = 0

6x–8 = 0, x+½ = 0

In one class, there are 2 of every 8 students in the class chewing
gum. If there are 32 students in the class, how many students are
chewing gum?

Answers

Answer:

8

Step-by-step explanation:

Answer:

8 people are chewing gum

Step-by-step explanation:

32/8=4, meaning there are 4 sets of 8 students.

If 2 students are chewing gum for every 8, and there are 32 students, that would mean that multiplying 4 by 2 to get 8 total kids chewing gum.

You could also say that 6*4=24, and 32-24=8 if you want to double check.

Answers

Answer:

5.5

Step-by-step explanation:

Given the set of data

5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

The average of the least and the greatest value is known as the midrange

The formula for calculating the midrange is expressed as shown:

Midrange = (Greatest value + Least value)/2

Given

Greatest value = 10

Least value = 1

Midrange = 10+1/2

Midrange = 11/2

Midrange = 5.5

Hence the midrange of the data is 5.5
