A roof rises 9.75 ft over a horizontal distance of 17.24 ft. What is the slope of the roof to the nearest hundredth? I keep getting the answer 0.65 but I am not condifant that this is correct. Is anyone getting this answer or something different?

the slope or Tangent of the angle would be 9.75/17.24= or 0.5655. Now if you need to know the angle take tan inverse and that would be 29.5 degrees.

Slope = the rise / horizontal distance
slope = 9.75 ft / 17.24 ft = .57
That is, if the horizontal distance you mentioned goes to the center of the room.
If the entire floor length is 17.24 ft, then you use only half that value:
slope = 9.75 ft / 8.62 ft = 1.13
Please offer more info.

Not completely sure what you're asking - do you want the slope of the roof as if it were on a cartesian plane, or do you want the slope in degrees (the pitch angle of the roof)?
The first is easy - divide rise by run: 9.75 / 17.24 = .57
The second requires trigonometry. The number calculated above is also the tangent of the angle you are looking for:
tan x = .57
Using a trigonometric table I find that the angle x = 29.49 degrees (or .51 radians)

The slope is rise over run, right?
slope= 9.75/17.24
slope=.56

9.75 ft / 17.24 ft = .565 = .57 rounded

take tan theta for your desired angle
here it is: ht/ horizontal distance= 9.75/17.24= .5655

slope is rise/run.
9.75/17.24 = .57
