Algebra.Com's Answer #275305 by stanbon(75887) ![]() You can put this solution on YOUR website! The horsepower produced by a steam engine varies directly as the number of revolutions per minute of its operation. if 1200 horsepower was produced when a machine was operated at 150 revolutions per minute, find the number of horsepower it will produce when it will operate at 170 revolutions per minute \n" ); document.write( "------------------ \n" ); document.write( "h = kr \n" ); document.write( "-- \n" ); document.write( "Solve for \"k\": \n" ); document.write( "1200 = k*150 \n" ); document.write( "k = 1200/150 = 8 \n" ); document.write( "----- \n" ); document.write( "Equation for this problem: \n" ); document.write( "h = 8r \n" ); document.write( "--- \n" ); document.write( "find the number of horsepower it will produce when it will operate at 170 revolutions per minute \n" ); document.write( "--- \n" ); document.write( "h = 8*170 = 1360 horsepower \n" ); document.write( "============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "======= \n" ); document.write( " |
