Question

you estimate that a tree is 45 ft tall. it is actually 58ft tall. can someone please help me find the percent error in the estimation and round to the nearest percent?

Answer 1

Well you could do proportions... I think..... Its been awhile.
\[\frac{ 45ft }{ 58ft }=\frac{ x }{ 100% }\]So cross multiply
4500= 58x Divide by 58 to get the percent 'right'
x = 77.58% Since this is percent right and not error Just minus by 100%
100% - 77.58% = 22.4% error
