Answer

To determine the number of significant figures in the number 65,000, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Number**: The number given is 65,000.

2. **Understand Significant Figures**: Significant figures are the digits in a number that contribute to its precision. This includes all non-zero digits, any zeros between significant digits, and any trailing zeros in a number with a decimal point.

3. **Apply the Rules for Significant Figures**:
- Non-zero digits (1-9) are always significant.
- Any zeros between significant digits are also significant.
- Leading zeros (zeros before the first non-zero digit) are not significant.
- Trailing zeros in a whole number without a decimal point are not considered significant.

4. **Analyze the Number 65,000**:
- The digits '6' and '5' are non-zero and thus significant.
- The trailing zeros (the three zeros after '5') are not significant because there is no decimal point present in the number.

5. **Count the Significant Figures**:
- From the analysis, the significant figures in 65,000 are '6' and '5'.
- Therefore, the total number of significant figures is 2.

### Final Answer:
The number 65,000 has **2 significant figures**.
