Triangle pqr is transformed to similar triangle p’q’r’: what is the scale factor of dilation? 1 over 2 1 over 3 1 over 4 1 over 5

1 over 2

Step-by-step explanation:

Triangle ABC has sides 2,2,2√2

Triangle A'B'C' has sided 1,1,√2

Scale (dilation) factor is less than one because A'B'C' is contracted not dilated. To get A' from A, multiply by 1/2.

The scale factor of dilation is:

                   1 over 2

The scale factor of dilation is the ratio of the length of the sides of the new triangle to the length of the corresponding sides of the original triangle.

Length of the side BC in original triangle is:

           BC= 2 units

and the length of the side B'C' in the transformed triangle is:

             B'C'= 1 units

Hence, the scale factor of the dilation is:

d

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
