The answer is $9.50 because you need to take the total of the popcorn which is $16.50. Then subtract that from $45 and get $28.50. The last step to do is divide $28.50 by three to get your final answer= $9.50 
The answer is= $9.50
        
                    
             
        
        
        
Given: lines l and m are parallel, and line t is a transversal.
angle pair result/justification
1 and 2 are equal (vertical angles)
6 and 8 are equal (corresponding angles)
1 and 4 are equal (alternate exterior angles)
4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)
Note: 
alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.
If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)
If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)
 
        
                    
             
        
        
        
Answer:
169.04 in² (nearest hundredth)
Step-by-step explanation:
Surface area of a cone =  r² +
r² +  r
r
(where r = radius of the base and  = slant height)
 = slant height)
Given slant height  = 10 and surface area = 188.5
 = 10 and surface area = 188.5
Surface area  =  r² +
r² +  r
r
188.5 =  r² + 10
r² + 10 r
r
  r² + 10
r² + 10 r - 188.5 = 0
r - 188.5 = 0
r =  = 4.219621117...
 = 4.219621117...
Volume of a cone = (1/3) r²h
r²h
(where r = radius of the base and h = height)
We need to find an expression for h in terms of  using Pythagoras' Theorem a² + b² = c², where a = radius, b = height and c = slant height
 using Pythagoras' Theorem a² + b² = c², where a = radius, b = height and c = slant height
r² + h² =  ²
²
h² =  ² - r²
² - r²
h = √( ² - r²)
² - r²)
Therefore, substituting found expression for h:
volume of a cone = (1/3) r²√(
r²√( ² - r²)
² - r²)
Given slant height  = 10 and r = 4.219621117...
 = 10 and r = 4.219621117...
volume = 169.0431969... = 169.04 in² (nearest hundredth)
