Answer:
a) 9000 ft-lb
b) 9000 ft-lb
Step-by-step explanation:
Equation for the work:
The equation for the work done is given by:

In which F is the force needed and d is the distance. The time does not interfere on the work.
A 300-lb gorilla climbs a tree to a height of 30 ft
This means that 
Thus

The work done in both cases is of 9000 ft-lb, as the work is not a function of time.
 
        
             
        
        
        
48-4=44,in the left 
6×7=42,in the right
44>42,so > is the answer
        
                    
             
        
        
        
Omar spent 600 dollars for earning 1800 reward points.
<em><u>Explanation</u></em>
Omar earns 300 reward points for every 100 dollars he spends. 
Suppose, he spent   dollar for 1800 reward points.
 dollar for 1800 reward points. 
Now <u>according to the ratio of "amount of money spent" and "reward points"</u> , the equation will be......

Thus, Omar spent 600 dollars for earning 1800 reward points.
 
        
                    
             
        
        
        
Answer:
The answer is b. 
Step-by-step explanation:
Square root 124, you'll get 29.10, after that once you simplify it, you will get the answer and you will have to do the formula, a^2 + b^2 = c^2 since it is a triangle.
