The scale factor is some number between 0 and 1 (not including either endpoint) because the image is smaller than the preimage.

Triangle ABC is the preimage, or the "before"; while triangle A'B'C' is the image, which is the "after".

preimage ----> image

before ----> after

Which type of transformation maps trapezoid PQRS onto trapezoid P'Q'R'S'? reflection rotation translation dilation

Keith_Richards [23]

Answer:

Dilation.

Step-by-step explanation:

From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .

Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.

But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.

Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".

Hailey rolls a twelve sided die, to choose a random number from one to twelve. What is the probability that the number hailey ro

Lemur [1.5K]

Answer:

7/12

Step-by-step explanation:

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.

Two digits are 10, 11, and 12.

Even numbers are 2, 4, 6, 8, 10, and 12.

So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)

P(Two digits or even) = 7/12

Which of the following describes a correct method for finding the sum -7/2+3/4

andreyandreev [35.5K]

Answer : (<span>C) Rewrite Using the LCD. Write the sum of the numerators over the common denominator. Simplify

</span>Rewrite Using the LCD
<span>-7/2+3/4 = -14/4 + 3/4

</span>Write the sum of the numerators over the common denominator:
-14/4 + 3/4 = 11/4

Simplify
11/4 = 2 3/4
