Problema Solution

alicia is 5 feet tall. she casts a shadow that measures 6 1/2 feet long at the same time that a sculpture in the park casts a shadow 12 feet long. which of the following is the approximate height of the sculpture?

Answer provided by our tutors

the shadows are a ratio

5 is to 6 1/2 as 12 is to x

lets keep x on top

(6 1/2)/5 = x/12

I would multiply through by 2 to remove the fraction in 6 1/2

13/5=2x/12

12*13/5=2x

31.5 = 2x

15.75=x

or

15 3/4 = x
