Answer:
circumference of circle = 2×pi×r
circumference of circle = 2×3.14×12.7
circumference of circle = 79.756 in
 
        
             
        
        
        
The answer is a, because the absolute value of x(the actual weight of the product) minus the target weight of 18.25 needs to be greater that the target weight difference of .36 so that it is outside the range.  So basically, any number outside of the range will be correct.You can plug in number that you know are in/ out of the acceptable range of numbers for this problem in.  
|18.62-18.25|>.36
.37>.36
18.62 is not in range.
        
                    
             
        
        
        
855=95d
855 minutes is equal to 95 minutes times the number of days run
        
             
        
        
        
Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2: 
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155  (1)
Step 3: 
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190    (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
       x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
 70  +  y = 155
   y = 155 - 70
    y = 85
