An office building casts a 90 foot shadow. At the same time of day, a 5 foot woman standing near the building casts an 8 foot shadow. What is the approximate height of the building to the nearest foot?

OpenStudy (anonymous):

OpenStudy (anonymous):

Your welcome

OpenStudy (anonymous):

Need to know how?

OpenStudy (anonymous):

yes plz

OpenStudy (anonymous):

5/8 = x/90 you would cross-multiply to get 8x = 450. Divide 450 by 8 to get 56.25, round it to 56

OpenStudy (anonymous):

Both fractions are the same

OpenStudy (anonymous):

It's easy once you get used to it
