For #12, they are vertical angles so 4x=84 degrees. Therefore you take 84 and decide by 4 and you get what x is (it’s 21)
(5+3)4
——— The answer is 16ft

B: 14x
C: -21
A and B
Step-by-step explanation:
says so
Answer:
8
Step-by-step explanation:
just do the comparation
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
