Final answer:
The total weight supported by the fixed ladder is the sum of the two loads, which is 500 pounds.
Step-by-step explanation:
If a fixed ladder supports two loads of 250 pounds each, the total weight supported by the ladder can be found by simply adding the two loads together. This is a basic arithmetic problem where you sum the weights:
- First load = 250 pounds
- Second load = 250 pounds
So, the total weight supported by the ladder is:
250 pounds + 250 pounds = 500 pounds.
Therefore, the correct answer is 1) 500 pounds.
