Okay I have been kind of late doing this but here it is!

Okay I had to do question 22# on page 51-54 on Mathlinks 8 and it was kind of normal doing this question so it wasn't hard or easy but here are my answers for these statements.

__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+__+

a) Express the ratio of rise to run in lowest terms.This Ratio describes the slope of the ramp.

So I counted the squares and it was 3 the rise of the ramp and 12 squares for the run on the ramp.
Okay my solution: 3:12 as in 3÷3=1 (12÷3=4) so now its 1:4.

b)Express the slope as a fraction, a decimal, and a percent.

So since this question is easy it is:
0.25 as a decimal 1/4 as a fraction 25% as a percent and 1:4 as a ratio

--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=-

c)Predict what effect of each of the following would have on the slope of the ramp:

-increase the rise
-decrease the rise
-increase the run
-decrease the run

This question was kind of hard to understand but i know what to do

When you increase the rise you increase the movement of the object rolling go farther on the slope.
When you decrease the rise you decrease the movement of the object rolling for less farther on the slope.
When you increase the run you decrease the movement of the object rolling go father on the slope.
When you decrease the run you increase the movement of the object rolling go less farther on the slope.

+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=

Also when you increase the slope and decrease the slop they have different chances of Probaility of rolling farther , less farther and also the same amount of speed of the slope that the object rolling is.
