Algebra.Com's Answer #450884 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! we know \"W varies inversely with square of T\", so we can write the proportion as\r \n" ); document.write( "\n" ); document.write( "W = k / (T^2) where k is the constant of proportionality\r \n" ); document.write( "\n" ); document.write( "for W=63 when T is 3 we have\r \n" ); document.write( "\n" ); document.write( "63 = k / 3^2 and k = 63 * 9 = 567\r \n" ); document.write( "\n" ); document.write( "now when T = 12, we have\r \n" ); document.write( "\n" ); document.write( "W = 567 / 12 = 47.3\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
