A percentage means "out of 100", but it is not unit-specific. This means that 1 percent is the same as 1/100 centimetres, 1/100 inches, 1/100 litres, 1/100 years etc... It is a proportion, not a measurement as such. To clarify, the slope is 1/100 inches. (i.e per every 100 inches you go forwards, you go down 1 inch).

Oh, dude, you're hitting me with some math now? Okay, okay. So, a 2 percent slope is like 2 inches of rise per 100 inches of run. And since there are 12 inches in a foot, you just divide 100 by 12 to get around 8.3 feet per foot on a 2 percent slope. Math is fun, right?
A 1 in 14 slope is where when the height raises 1 inch from the slope it is equal to the road 14 inches up the hill.
To convert .25 inch per foot into degrees or percent slope, you first need to determine the rise over the run. In this case, .25 inch per foot is equivalent to a rise of .25 inches for every 12 inches of horizontal distance (1 foot). To convert this into degrees, you can use the arctangent function: arctan(.25/12) ≈ 1.19 degrees. To convert this into percent slope, you can use the formula: percent slope = (rise / run) x 100. In this case, it would be (.25/12) x 100 ≈ 2.08% slope.
8 and 1/3 feet of rope = 100 inches.30 percent of the rope = 30 inches.
The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.
