Answer:
1.04 inch
Step-by-step explanation:
Given: Old house has a basement stairways with 7.25 inch vertical riser and 7 inch horizontal treads.
Remember; horizontal treads is known as run in steps.
Now, calculating the slope of the stairways.
Formula: [tex]Slope= \frac{Rise}{Run}[/tex]
Rise= 7.25 inch
Run= 7 inch.
Subtituting the value in the formula
Slope= [tex]\frac{7.25}{7}= 1.0357 \approx 1.04[/tex] (∵ Round to two decimal)
∴ Slope of stairways is 1.04.
