1. nicole usually scores between 89%
and 100% on her math quizzes,
unless the quiz is the day after a track
meet. on the quizzes she takes right
after a track meet, she has about an
11% decrease in her scores. if nicole
had a track meet the day before a
quiz, what would she score on the
quiz?
a between 70% and 78%
b between 79% and 89%
c between 90% and 99%
d between 100% and 111%

The Answer is: B. 79% and 89%

Step-by-step explanation:

Subtract 11% from 89 and 100 to get the range:

89 - (89*.11) =

89 - 9.79 = 79.21

100 - (100*.11) =

100 - 11 = 89

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
