Answer :
Sure, let's solve this step by step:
1. Identify the numbers to be added:
- We have 0.9 pound
- We also have 137 pounds
2. Perform the addition:
- [tex]\( 137 + 0.9 = 137.9 \)[/tex]
3. Determine the number of significant digits:
- The number 137 has 3 significant digits.
- The number 0.9 has 1 significant digit after the decimal point.
4. Expressing the result with the correct precision:
- When adding numbers, the result should be rounded to the least number of decimal places of the addends. In this case, 0.9 has 1 decimal place, so our result should also be rounded to 1 decimal place.
Thus, the result is:
137.9 pounds
Your weight before you went for a run is 137.9 pounds.
