I need help with diagrams 5 and 6, as well as the following question, as the homeschooling course's intructional video does not explain what to do when you have a whole number as a slope instead of a fraction.

 

The slope of a street is 0.54. If it covers 28 metres of horizontal distance, what is the rise of the street?

 

I would really appreciate assistance. Thank you. smiley

 

Note: If the picture does not show up, I could email it to you.

This means that for every 1 m change in horizontal distance, the street rises .54m

 

[Note that when  the slope is just given as a single number, we can put that number over 1.....so here....  0.54   = 0.54 / 1       .....and that's the slope ]

 

So........28(.54)  = 15.12 m   is the rise

 

[Unfortunately your pictures don't post ]

 

 

cool cool cool
