Barbara and Steve are sitting on opposite ends of a 12-foot-long seesaw. The fulcrum (support) at the center of the seesaw is a 3 feet high. When Steve's end of the seesaw is touching the ground, how many feet off the ground is Barbara's end of the seesaw?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
