To find the rise between the given elevations and the slope length, we can follow these steps:

1. Determine the total elevation difference (rise):

   • Hub elevation (el) = 50
   • Top of slope (T.o.s) = 25
   • Bottom of slope (B.o.s) = 13

   The elevation difference from Hub to B.o.s: $\text{Rise} = \text{Hub el} - \text{B.o.s} = 50 - 13 = 37$

2. Calculate the slope length:

   • The slope length given is 35 feet.

3. Calculate the rise per 5 feet: We need to calculate how much rise occurs for every 5 feet along the slope.

   Using the total rise: $\text{Total length} = 35 \text{ feet}$ Since the total rise is 37 feet, we can calculate the rise per foot: $\text{Rise per foot} = \frac{37 \text{ feet}}{35 \text{ feet}} \approx 1.06 \text{ feet}$ To find the rise for every 5 feet: $\text{Rise per 5 feet} = 5 \times 1.06 \approx 5.3 \text{ feet}$

Summary:

• Total rise: 37 feet
• Rise every 5 feet: approximately 5.3 feet
