The natural stride up a certain staircase has a slope of 3/5, meaning that a run of 5 inches has a rise of 3 inches.
The model for a standard staircase is y=(3/5)x
Find the rise for a staircase constructed at a mansion which has a run of 12 inches.

To find the rise for a staircase constructed at a mansion with a run of 12 inches, you can use the equation for the standard staircase model.
The equation given is y = (3/5)x, where x represents the run and y represents the rise.
In this case, we want to find the rise (y) for a run (x) of 12 inches. So, we need to substitute x = 12 into the equation.
y = (3/5)x
y = (3/5)(12) (substituting x = 12)
y = (3/5)(12)
y = 36/5
Therefore, the rise for a staircase with a run of 12 inches in the mansion would be 36/5 inches.
To find the rise for a staircase with a run of 12 inches, you can use the equation y = (3/5)x, where y represents the rise and x represents the run.
In this case, the run (x) is 12 inches. You can substitute this value into the equation:
y = (3/5)*12
Simplifying the equation:
y = (3/5)*12
y = (3*12)/5
y = 36/5
y = 7.2
Therefore, the rise of the staircase constructed at the mansion with a run of 12 inches would be 7.2 inches.
