Vb : Vs
b for big and s for small
4/3 π rb³ : 4/3 π rs³ (since there are 4/3 and π on both side, we can eliminate them so)
Vb : Vs = rb³ : rs³
Vb : Vs = (2rs)³ : rs³
Vb : Vs = 8rs³ : rs³ (delete the r³ on both side)
Vb : Vs = 8 : 1
so Vb is 8 times larger in volume than the small one
The number y, decreased by 12
In a random sample of students at a middle school 24 wanted to change the mascot and 30 wanted to keep the current mascot.
So total number of students in the sample = 30+24= 54
Number of students in random sample who wanted to keep the current mascot = 30
So out of 54 students 30 wanted to keep current mascot.
So for 1140 students = (30/54)*1140 = 633 students want to keep the currect mascot.
Answer: Third option 633 students.
