Answer:
The answer is $61.20
Step-by-step explanation:
First you multiply 72 by .15 (which is 15% converted to a decimal), which gives you 10.8. You then subtract 10.8 from 72.
 
        
             
        
        
        
Answer:
It says to Graph y = 1/2x - 4
So equation y = 1/2x - 4
this corresponds to slope intercept form which is y = mx + b
M = slope = rise / run
B =  y - intercept
First, start at the origin, (0,0)
Then go down 4, you should now be on the coordinate (0,4)
Now we need to use the slope.
The slope is 1 / 2, this means rise 1, run 2 (in this case 2 to the right because it is positive)
So, start at (0 , 4) and go up 1 unit then 2 to the right, then place a dot, keep repeating until you meet the end of the paper.
Then do the opposite so that you can graph the other side.
Down 1 and 2 to the left.
 
        
                    
             
        
        
        
a) 9/212 = #mph
b)0.000142045 Miles / 0.000277778 hours = # mph
Step-by-step explanation:
a) 9/212 = #mph
b) 
1)9 inches divide the length value by 63360 is 0.000142045 Miles
2) 1 hour  3600 seconds in ones hour so 1/3600 =0.000277778
3) take miles/hour 
0.000142045 Miles / 0.000277778 hours = # mph
 
        
             
        
        
        
I think u have to divide and u get ur answer hope it helps
        
             
        
        
        
3 ounces of 80-proof rum approximately contains 200,000 cal.
Now, we need to convert the cal into kcal. We know that:
1 cal = 1000 kcal
Therefore,
200,000 cal = 200 kcal
