Algebra.Com's Answer #487392 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Time(T) is inversely proportional to the number of painters (P) \n" ); document.write( "T = k/P \n" ); document.write( "k is the constant of proportionality. \n" ); document.write( "To find k, use information given. \n" ); document.write( "If 3 painters can paint a house in 6 hours. \n" ); document.write( "6 = k/3 \n" ); document.write( "k = 18 \n" ); document.write( "Formula: \n" ); document.write( "T = 18/P \n" ); document.write( "Using 12 painters: \n" ); document.write( "T = 18/12 \n" ); document.write( "T = 1.5 hours. \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
