if a 5 foot 6 person cast a 11 foot shadow and a nearby tree casts a 20 foot shadow how tall is the tree
\n" ); document.write( "5 feet 6 means 5 feet and 6 inches. Change 6 inches to .5 ft (1/2 foot)\r
\n" ); document.write( "\n" ); document.write( "Write a proportion with the given information. There is more than one way to write this proportion. I will write it as:\r
\n" ); document.write( "\n" ); document.write( "person's height /person's shadow = tree's height/tree's shadow\r
\n" ); document.write( "\n" ); document.write( "5.5/11 = x/20 I used x for the unknown height of the tree.
\n" ); document.write( " Cross multiply
\n" ); document.write( "11x = 110 Now divide both sides by 11
\n" ); document.write( "x=10
\n" ); document.write( "
\n" ); document.write( "
