First fine the dialation divide 6 by 4 you get 1.5 so the dialation of these shapes is 1.5 now you just simply find the measurments.... 9 divided by 1.5 is 6 so BC is 6. now 7*1.5 is 10.5 so QR is 10.5 now the angles never change in a dialation so <P= 86*.
Hope this helped you!!! have an amazing day!

All you do is find the scale factor and go from there so
AB and side QP are similar so the scale factor is 1.5
In order to find QR just multiply 7*1.5=10.5
Then to find BC you just do just multiply it by 2/3*9=6
The angle is 86 degrees

Miguel conducts a survey of 750 college students to see how many of them have a part-time job. His results show that 500 of the

Bingel [31]

Miguel: 500 out of 750 students have part time jobs.

500 ÷ 250 = 2
750 ÷ 250 = 3

500:750 = 2:3

A) 200 out of 300 ⇒ 200/100 and 300/100 ⇒ 2:3
B) 700 out of 1100 ⇒ 700/100 and 1100/100 ⇒ 7:11
C) 800 out of 1200 ⇒ 800/400 and 1200/400 ⇒ 2:3
D) 9000 out of 1300 ⇒ 9000/100 and 1300/100 ⇒ 90:13

Among the choices, Choice B could represent Kureshi's Data because it is not proportional to the data of Miguel.

Choice D is not possible. You cannot have a result that is way beyond the scope of your population. It is impossible to get 9000 students out of only 1300 students.
