Answer:
175
Step-by-step explanation:
5/24 = 0.208 percentage of defective bolts
scale up to 840 bolts by finding 20.8% of defective bolts
840*20.8 = 175
 
        
             
        
        
        
The "midpoint formula" is the same as the "average formula:"
x-coordinate of the midpoint = average of -2 and 10:
 = (-2 + 10) / 2 = 4
y-coordinate of the midpoint = average of 3 and 3:
 = (3+3) / 2 = 3
Thus, the midpoint of the given line segment is (4,3).
 
        
             
        
        
        
Answer: 9
Step-by-step explanation: 
Add 20, 12, and 32 together then divide by 7 because it says "One week" and a week is 7 days. So, it should be like 20 +12 + 32= 64
64 / (divided by) 7 = 9
 
        
             
        
        
        
1 and 1/2 hours each night
1+1+1+1+1= 5
1/2+1/2+1/2+1/2+1/2= 2.5
5+2.5= 7.5
7.5 hours or & and a half
