Algebra.Com's Answer #612934 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! You can call the shed-building time [ t = hrs x days ] \n" ); document.write( "since that gives you the total time, \n" ); document.write( "The rate of building 1 shed is: \n" ); document.write( "[ 1 shed/t ] \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "----------- \n" ); document.write( "Since this is the rate for \n" ); document.write( "divide by \n" ); document.write( "man to build 1 shed \n" ); document.write( " \n" ); document.write( "------------------------- \n" ); document.write( " \n" ); document.write( "Let \n" ); document.write( " \n" ); document.write( "This is: [ rate ]x[ time ] = [ number of sheds ] \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "They take 6 days \n" ); document.write( "------------------- \n" ); document.write( "You can do it this way, too: \n" ); document.write( "1/3 as many men take 3 times as long, so \n" ); document.write( "4 men take 120 hrs \n" ); document.write( "------------------- \n" ); document.write( "Twice that many men take 1/2 as long, so \n" ); document.write( "8 men take 60 hrs \n" ); document.write( "----------------- \n" ); document.write( " \n" ); document.write( "This is [ hrs / ( hrs/day ) ] = [ days ] \n" ); document.write( "------------------------------- \n" ); document.write( "This isn't exactly an equation, \n" ); document.write( "but I think it gives some insight \n" ); document.write( " \n" ); document.write( " |
