Answer:
$448 million
Step-by-step explanation:
When it is 2011, t=11, so

 
        
             
        
        
        
Height of the pentagon = 9 ft
Edge of base = 3 ft 

s is the length of any side = 3
n is the number of sides = 5 
tan is the tangent function calculated in degrees 

Volume of the pentagon = area of base (height )
Volume of the pentagon = 15.4852 (9)
Volume of the pentagon = 139.366
Volume of the pentagon = 139.37 cu.ft
 
        
                    
             
        
        
        
X = y + 11
2x + y = -2
2(y + 11) + y = -2
2y + 22 + y = -2
3y + 22 = -2
3y = -24
y = -8
x = y + 11
x = -8 + 11
x = 3
Solution set {3, -8} (C)
        
             
        
        
        
U need to show an example of the tiles in order for people to answer this
        
             
        
        
        
I don't know what you are asking for the first part of the question but 36+23+17 = 76
Hope this helped a little! :)
