Answer:  a2 + 152 = 362
Step-by-step explanation:
 
        
             
        
        
        
You can calculate the difference/vector of both points:

then calculate the magnitude/length like pythagoras
 
 
        
        
        
The first thing you must do is to calculate the weight of the gravel (w) that the truck holds (7.5 yards³). So, you have:
 If the weight of 1 yard³ is 1.48 tons, then the weight of 7.5 yards³ is:
 w=7.5x1.48 tons
 w=11.1 tons
 The problem says that the gravel will be placed in containers that each hold 3.7 tons of gravel,so, If they need 1 cotainer to place 3.7 tons, how many containers they need to place 11.1 tons?
 1 container-------3.7 tons of gravel
                 x-------11.1 tons of gravel
 x=(11.1x1)/3.7
 x=11.1/3.7
 x=3 containers
 H<span>ow many containers of this size are needed to hold all the gravel from one truck?

 The answer is: 3 containers.
