Answer:
503 $1 tickets sold.
Step-by-step explanation:
Use two equations  
Let x = number of $1 tickets sold  
Let y = number of $1.50 tickets sold  
x + y = 739  
1x + (1.5)y = 857  
First equation ==> y = 739 - x  
Plug this into the second equation  
x + (1.5)(739 - x) = 857  
x + 1108.5 - 1.5x = 857  
- 0.5x = -251.5  
x = 503  
There were 503 $1 tickets sold.  
To find the number of $1.50 tickets, just plug this value of x into either one of the equations.  
(503) + y = 739       (739 - 503 = 236)
y = 236  
There were 236 $1.50 tickets sold.
 
        
             
        
        
        
Answer:
 3142.86 cubic cm 
Step-by-step explanation:
volume of cone is given by formula 
volume of cone = 1/3(area of base*height)
Given radius of base = 10cm
we know area of circle is given by  where r is radius of circle
 where r is radius of circle
thus area of base of cone is calculated below

 area of base of cone is 314.2857 square cm
height = 30 cm
Thus volume of cone  = 1/3* (area of base*height)
                                    = 1/3(314.2857*30)
                                    = 1/3 *9428.571 = 3142.857.
Thus, volume of cone is 3142.857 cubic cm.
volume of cone  to the nearest hundredth is 3142.86 cubic cm
