Algebra.Com's Answer #61090 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The body mass index is a measure of the risk of heart disease. It is given by the following formula:\r \n" ); document.write( "\n" ); document.write( " I = 704.5 W\r \n" ); document.write( "\n" ); document.write( "H2 Where W = weight in lbs and H = height in inches \r \n" ); document.write( "\n" ); document.write( " An index greater than 25% indicates that a person IS at risk for a heart attack. If Mary’s height is 65 inches what should her weight be maintained at or under? \n" ); document.write( ": \n" ); document.write( "I am going to assume that the formula should be: \n" ); document.write( "I = \n" ); document.write( ": \n" ); document.write( "Find W \n" ); document.write( " \n" ); document.write( " \n" ); document.write( ": \n" ); document.write( "Multiply both sides by 4225 and you have: \n" ); document.write( "704.5W =< 25*4225 \n" ); document.write( ": \n" ); document.write( "704.5W =< 105625 \n" ); document.write( ": \n" ); document.write( "Divide both sides by 704.5 and you have: \n" ); document.write( "W =< \n" ); document.write( "W =< 149.9 lb: \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution on good calc: enter: (704.5*149.9)/65^2 = 24.995 ~ 25%\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
