Question

how does the slope change if the bottom is lowered to 15 inches off the ground and width extended to 13 feet (steeper or less steep)? find the slope of the main portion (between the yellow lines) with the above changes made. the rise decreased and the run increased that makes the slope smaller which causes it to become more steep.

Explanation:

Step1: Convert bottom height to feet

15 inches = $\frac{15}{12} = 1.25$ ft

Step2: Calculate vertical rise

Rise = Total height - Bottom height = $8 - 1.25 = 6.75$ ft

Step3: Determine horizontal run

Run = 13 ft (given extended width)

Step4: Compute slope (rise/run)

Slope = $\frac{6.75}{13} = \frac{27}{52}$

Answer:

Less steep, $\frac{27}{52}$
