50 ft

Answer 1

Well basically all you do here is add 14 and 36 to get your answer. You finish :)

Answer 2

y(final)-y(initial)=y(total) You want to solve for y(total). y(final) is the roof elevation. an y(initial) is your basement elevation.

Answer 3

negative or positive? :/

Answer 4

If you walk up the stairs what do you think the displacement should be?

Answer 5

positive?

Answer 6

Answer 8

because elavation is going up?

Answer 9

Correct

Answer 10

@TheBallisticOne, That does not look correct because you first are basically adding a negative number and then after taking the difference you take the absolute value.

Answer 11

can i ask you guys some more? :)
