To determine which of the given weights are more precise than 10 pounds, we need to understand what "precision" refers to in this context. Precision can often mean the number of decimal places in a measurement.
Given weights are:
- A. 30 pounds
- B. 50 pounds
- C. 15.5 pounds
- D. 8.0 pounds
The weight "10 pounds" does not have any decimal places (it's an integer). So, any weight with one or more decimal places can be considered more precise than 10 pounds.
Let's analyze each option:
- A. 30 pounds: This weight is a whole number with no decimal places.
- B. 50 pounds: This weight is also a whole number with no decimal places.
- C. 15.5 pounds: This weight has one decimal place.
- D. 8.0 pounds: This weight has one decimal place.
Both options C (15.5 pounds) and D (8.0 pounds) have more decimal places than 10 pounds. Therefore, they are more precise.
So, the correct answers are:
☐ C. 15.5 pounds
☐ D. 8.0 pounds
