45 
Step-by-step explanation:
Multiply 9 · 10 = 90 then divided by 2 = 45
Answer:
2√5
Step-by-step explanation:
The radius is the distance from the center to a point anywhere along the edge of the circle. To find the distance between these two points, use the distance formula.

S = 4
3(10) = 10 + 5s
30 = 10 + 5s
30 - 10 = 5s
20 = 5s
20 ÷ 5 = s
4 = s
Work:
624 divided by 12 equals 52
answer:
52 dozens
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.
