Asteel bar that originally weighed 15.62 pounds is turned down on a lathe until it weighs 14.48 pounds. what percent of the original bar is waste? (round your answer to the nearest tenth.)

1. The information, given in the problem, that you need to solve it, is:
 
 - A steel bar that originally weighed 15.62 pounds.
 - Then it weighs 14.48 pounds.
 
 2. Therefore:
 
 15.62 pounds100%
 14.48 poundsx
 
 x=(14.48)(100)/15.62
 x=92.70%
 
 3. Now, you must substract both percents:
 
 =100%-92.70%
 =10.38%
 
 The answer is: 7.3%
 
 
 

   

 
 

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
