Answer:
$132
Step-by-step explanation:
We can use a ratio to solve
4 tickets 11 tickets
-------------- = ------------
$48 x dollars
4*x = 48*11
4x = 528
Divide each side by 4
4x/4 = 528/4
x =132
The volume of the resulting ring is (4/3)π(R³ - r³)

Volume</h3>
The volume of an object is the amount of space occupied by the object in three dimension.
The volume (V) of a sphere is given by:
V = (4/3)πr³
Where r is the radius of the sphere.
For the sphere with radius R, volume is:
V = (4/3)πR³
The hole with radius r, has a volume of:
V = (4/3)πr³
Hence volume of the ring = (4/3)πR³ - (4/3)πr³ = (4/3)π(R³ - r³)
The volume of the resulting ring is (4/3)π(R³ - r³)

Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
