The answer should be 280.
Answer:
97
Step-by-step explanation:
9+7*9=72
9+18+10=37
10+10+7=27
7+9*10=97
x=9 i.e. option B is the answer.
Explanation:
Given that in triangle ABC, sides AB and BC are 36 and 28 units.
BD is angle bisector of angle B meeting AC at point D
Also AC = 16 cm.
We know that by angle bisector theorem,
AB/AC = BD/DC
Or x/DC = 36/28
By compendo and dividendo principle, we rewrite as
Or x/x+DC = 36/(28+36)
x/16 = 36/64
x = 36(16)/64 = 9 units.
Answer:
g = -0.5
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
Answer:
V = 15 in.³
Step-by-step explanation:
The original cylinder has radius r and height h.
V = πr²h
Its volume is 30 in.³, so
πr²h = 30 in.³
The new cylinder has radius (1/2)r and height 2h.
Its volume is
V = π(r/2)²(2h)
V = πr² × 2h/4
V = πr²h/2
πr²h is the volume of the original cylinder, and it is 30 in.³.
V = 30 in.³/2
V = 15 in.³
