### Scribepost For January 6 2009

Today Mr. Harbeck said that if we haven't scribe yet we should pick a question. Here is question number 7.

7. What is the height of
the wheelchair ramp?
Give your answer to
the nearest tenth of a centimetre.
c² - b² = a²
80² - 79² = a²
(80x80) - (79-79) = a²
6400 - 6241 = a²
159 = a²
√159 = √a²
12.6cm= a
The wheelchair ramp would be 12.6 cm tall.
Thanks for reading my scribe!

Good job Ralph. You did a good job on explaining the formula and such. You also put different colours for different parts of the question and answer. Keep up the good job my friend! :)
