What is the slope of a staircase when the measurement is 9 inch treads and 8 1.2 inch rises?

The slope is 8-1/2 divided by 9 = 0.9444...(rounded, repeating)
The angle of the slope is whatever angle has a tangent of (8-1/2)/9 .
That angle is 43.36 degrees. (rounded)
That makes sense, because we know that if the tread and riser were equal,
then the angle would be 45 degrees.

Does a spiral staircase have a constant slope?
Previous answer: "No because the line is not straight and the points of the slop is in different ares." The above is ambiguous. You need to define the term slope. The slope of a helix (or any curve) is normally defined as the slope of a line that is tangent to the helix (curve). And then you need to define, slope with respect to what? Normally that would be slope with respect to a horizontal plane. That slope, by definition, is constant for a helix with a vertical axis. The value of the slope of such a helix is pitch / (2*pi*R), where R is the radius from the axis. Then you have to consider where on the staircase you are. A staircase is not a single helix. It has width, or different radii. If you are walking up stairs at a constant radius R from the axis (on a helix), then the slope is constant. In any case, the average slope of the stairs varies with the radius R on which you are walking, so that would not be a constant.
What is a road on a slope?
When determining the measurement of slope on a road, the equations are for grade (gradient). The formula is grade = (rise ÷ slope length) * 100
Can the slope of a line be a fraction?
Of course. If the line rises 18 units for every 27 horizontal units,then its slope is 2/3 .
The slope of a line is the rate at which the line increases or slope?
The slope of a line is rise over run. That is to say, how many units the line rises for every unit it travels laterally.
What does slope tell you about inches and centimeters?
Nothing. Slope is a measure used in graphing and algebra. Feet and inches are units of linear measurement.
How would you use the height of the risers and the depth of the treads to measure the slope of a staircase?
It is a right-angled triangle where the height is the vertical leg (a) and the depth is the horizontal leg (b). a/b = tan of slope angle Slope angle = arctan(a/b)
What is the code for stairs treads to risers?
I need to know what the codes are on stairs? Treads@risers an hand rails ?for what degree of slope
Is stairs a wedge?
A staircase is more like a stepped slope.
How would you define positive slope?
a line with a positive slope rises from left to right

What type of slope does a line that rises from left to right have?
Positive
What area is between the continental slope and ocean basin?
continental rises
What does it mean when it says then interpret this slope as a rate of change?
It means express the slope along with its measurement units.
