Answer:
Area=BH Answer is 242
Step-by-step explanation:
For the first drain the equation you need would be: 2n = 108
for drain B your equation would be: 5n = 108
these are your equations because a number times the amount of water the drain drains per minute will equal 108
to solve use inverse operations and divide 108 by the amount of water the drain drains in one minutes
Drain A- 108/2 = 54
it takes 54 minutes for drain a to empty a pool with 108 gallons of water
Drain B- 108/5 = 21.6
it takes 21.6 minutes for drain b to empty a pool with 108 gallons of water in it<span />

Hey there!
x+x+1/4+x+2/4
3x+0.75=6.75
3x=6
x=2
The lines are 2, 2 1/4, and 2 2/4.

Answer:
the third one
Step-by-step explanation:
Answer:
the formula for the volume of a sphere is

r is the radius, which is half the diameter. Since the diameter of the whole sphere is 18 the radius would be half of that, which is 9. If you plug 9 into the formula you get 3052.08in.cubed. Now you must find the volume of the smaller core, the diameter of the core is 3, so the radius is 1.5 and if you plug that into the formula you get 14.13in.cubed. Since you're finding only the volume of the outside layer, you would subtract the volume of the core from the whole sphere, so 3052.08-14.13=3037.95
Your answer is 3037.95in.cubed
