Joe completes an average of (10 ft)/(5 h) = 2 ft/hour. Bill completes an average of (10 ft)/(4 h) = 2.5 ft/hour. Together, they complete 2+2.5 = 4.5 ft/hour. At that rate, it will take them
... (120 ft)/(4.5 ft/h) = 26 2/3 h
 
        
                    
             
        
        
        
Answer:
The scale factor would be 1/2.
Step-by-step explanation:
2 of the sides both are 4 units.
If you go to figure B, it got smaller.
So in this case, you would divide.
On figure B, 2 of the sides are 2 units.
If you did it in reverse, you would get 2 because 2 times 2 is 4.
But we divide, so 4/2 is 2, so the scale factor would be:
1/2

Answer: The height of wall is 10.5 feet.
Step-by-step explanation:
Since we have given that 
Number of bricks to build = 1470
Length of wall = 20 feet
We need to find the height of wall.
As we know that 
Bricklayer's formula is given by

Hence, the height of wall is 10.5 feet.
