Algebra.Com's Answer #366300 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The ratio of the weight of an object on Mars to its weight on Earth is 9 to 25. \n" ); document.write( " If a person weighs 120 pounds on Earth, how much would the person weigh on Mars? \n" ); document.write( ": \n" ); document.write( "These are just ratio equations, quite easy. \n" ); document.write( "let m = his weight on Mars \n" ); document.write( " \n" ); document.write( "cross multiply \n" ); document.write( "25m = 120 * 9 \n" ); document.write( "25m = 1080 \n" ); document.write( "m = \n" ); document.write( "m = 43.2 lb on Mars \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "A flagpole casts a shadow of 8.5 meters long. \n" ); document.write( " If an algebra student 1.6 meters tall casts a shadow of 2.0 meters long at the same time and location, how tall is the flagpole in meters? \n" ); document.write( ": \n" ); document.write( "Similar triangles, the corresponding sides have the same ratio \n" ); document.write( "let f = height of the flag pole \n" ); document.write( " \n" ); document.write( "Cross multiply \n" ); document.write( "2f = 1.6 * 8.5 \n" ); document.write( ": \n" ); document.write( "You should be able to finish this one, just like the 1st one \n" ); document.write( " |
