## anonymous 4 years ago A person 2.5 ft tall casts a shadow of 3 ft. How long is a shadow of a pole that is 6.7 ft tall?

1. anonymous

use ratio and proportion $2.5 : 3 = 6.7 : x$ $\implies 3 \times 6.7 = 2.5x$ do you get it?

2. anonymous

so the answer is 2.5x? because the options given are 5.5 ft. 7 ft. 8 ft.

3. anonymous

what is 3 * 6.7?

4. anonymous

(use a calculator)

5. anonymous

3 * 6.7 is 20.1

6. anonymous

now divide it by 2.5

7. anonymous

oooooooooooh so its 8ft right?

8. anonymous

yep

9. anonymous
