Answer:
24 hours
Step-by-step explanation:
The computation of the number of hours taken by Bobby to build the robot by himself is shown below:
Given that 
Bobby could take 12 hours
Together they could build in 8 hours
So based on the above information 
 the number of hours taken by Bobby to build the robot by himself is 
Let us assume the above line be x
So, 

x = 24 hours
 
        
             
        
        
        
To find X and Y X is horizontal Y is vertical, so that means SCP is horizontal and EF or a B is oops sorry all the way around
        
             
        
        
        
Answer: a.) 3
Step-by-step explanation: An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).
 
        
                    
             
        
        
        
16•0.10= 1.60$ 
8•0.05= 0.40¢
12•0.25= 3.00$
1.60$+0.40¢+3.00$= 5.00$ 
3•0.10= 0.30¢
5•0.05= 0.25¢
0.30¢+0.25¢= 0.55¢
5.00$-0.55¢= 4.45$
4.45$ is left in the piggy bank.
