Rashid [163]

Answer:

3/18, or simplified, he has a 1/6 chance of grabbing an adventure book.

Step-by-step explanation:

6 + 5 + 4 + 3 = 18. There's 3 adventure books, which makes it so that he has a 3/18 chance of it being an adventure book. How did I simplify? 18 ÷ 3 = 6, 3 ÷ 3 = 1.

in each of the following graphs, the two given polygons are similar. write precisely a single dilation (coordinated of center an

Sergeeva-Olga [200]

The single dilation of the shape is a dilation by a scale factor of 1.5 with center R

<h3>How to determine the dilation rule?</h3>

From the graph, we have the center of dilation to be point R.

This is so because R = R'

Also, we have:

R = (-1, -4)

S = (2, 0)

S' = (3.5, 2)

Calculate the distance RS and RS' using

$d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2$

This gives

$RS = \sqrt{(0 + 4)^2 + (2+ 1)^2} = 5$

$RS' = \sqrt{(2 + 4)^2 + (3.5+ 1)^2} = 7.5$

Divide RS' by RS to determine the scale factor (k)

k = 7.5/5

k = 1.5

Hence, the single dilation of the shape is a dilation by a scale factor of 1.5 across point R
