Answer:
V = 1134.9
Step-by-step explanation:
Since 
Firstly we need to divide 17 by 2 to get the radius which is 8.5 
Then we need to solve by putting the values in...
 x

 x 
= 1134.9
 
        
             
        
        
        
Volume of a cone = PI x r^2 x h/3
Volume = PI x 5^2 x 9/3
Volume = 235.62 cubic cm.
Volume of a block of wax = L x W x H
Volume = 2 x 4 x 3 = 24 cubic cm.
Total number of blocks = Volume of cone / volume of blocks:
235.62 / 24 = 9.82
Round up to 10.
They will need 10 blocks.
 
        
             
        
        
        
Answer:
A) 13.50>9.00
B) $7
Step-by-step explanation:
A) 4.50*3=13.50 (Peter) 4.50*2=9.00 (Cindy)
B) Cindy would have to earn $7 an hour if she works 2 hours per day because 7*2=14
 
        
                    
             
        
        
        
From the given scenario in this item, we can say that the sum of x and y is 500. By the aluminum balance, the equation that we can formulate from this,
                            0.25x + 0.40y = (500)(0.35)
The system of linear equations that can best express the given is,
                                   x + y = 500
                                0.25x + 0.40y = 175
