## anonymous 3 years ago The distance from the river bank to a nearby fallen tree is 3.6 meters. The tree has fallen parallet to the river bank and is 1.44 m tall' The tip of the tree is approximately 2.4 meters from the wateffall. Using these measurements, find the distance across this section of the river.

Hmm. This is proportions again :|

3. anonymous

Yes. It's okay to not help me if you don't want to.

4. anonymous

Okay. I'll attempt it myself.

5. Opcode

Try setting it up ^_^.

6. anonymous

Okay.

i have to draw it too. is that a good drawing"?

9. anonymous

tbe circle is the river.

10. Opcode

Errm sure?

11. anonymous

Lol. Okay.

12. anonymous

hmm

13. anonymous

i did 3.6-2.4 and got 1.2

14. anonymous

iI'm sorry, I don't get it.

15. Opcode

Okay let me think ^_^.

16. anonymous

i apologize.

3.6 meters. 1.44 m tall 2.4 meters from the waterfall. Okay. I've removed the unneeded information. $$\huge\frac{3.6}{1.44} \times \frac {2.4} {x}$$ Cross multiply... 3.456 = 3.6x Divide each side by 3.6

The distance is 0.96 meters... Hmm.

20. anonymous

It is, indeed.

21. Opcode

No... 0.96 is small... It doesn't make any sense... -.-

22. anonymous

I'm just saying I got that, too.

23. Opcode

WAIT! 0.96 meters = 3.1496063 feet So it's legit ^_^.

24. anonymous

ooh. ok. and how'd you figure out how to set the proportion up?

25. Opcode

I removed things that are unnecessary for the word problems. Then I simply set it up.

26. anonymous

Oh. Such as? The river bank thing?

27. Opcode

Errm what?

28. anonymous

Never mind. Disregard :D and thanks :)

29. Opcode

Okay.

30. anonymous

Oh,Kami: Could you draw a picture of the situation?

31. Opcode

Okay... That's complex. |dw:1360586879531:dw|

32. anonymous

thanks:)

33. Opcode

No problem :)
