Algebra.Com's Answer #74954 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! You can solve this problem using proportions that are set up as follows: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The height of the woman is 5 ft 6 inches and this is 5.5 feet. Her shadow is 12 ft long. \n" ); document.write( "Substituting these values results in: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The shadow of the tree is 45 feet. Substitute this and you get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "You can get rid of the denominator of 45 by multiplying both sides of the equation by 45. \n" ); document.write( "When you do that the equation becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "You are now left with the equation: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Solve for the Height of the tree by multiplying out the numerator of 45*5.5 and dividing that \n" ); document.write( "product by 12 to get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The tree is 20.625 feet tall. This converts to 20 ft 7.5 inches. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem a little better ... \n" ); document.write( ".\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
