Question

Using a number line, what whole number and rational number to the nearest half is square root 97
between?(1 point)
square root 97 is between BLANK and BLANK

Answer 1

the answer was actually 9.5 and 10 but why

Answer 2

To find the values between which \(\sqrt{97}\) falls, we first need to calculate the square root of 97.

Since \(9^2 = 81\) and \(10^2 = 100\), we know that:

\[
9 < \sqrt{97} < 10
\]

To approximate \(\sqrt{97}\) further, we can test the numbers between 9 and 10:

- \(9.5^2 = 90.25\) (too low)
- \(9.6^2 = 92.16\) (too low)
- \(9.7^2 = 94.09\) (too low)
- \(9.8^2 = 96.04\) (too low)
- \(9.9^2 = 98.01\) (too high)

So we can conclude:

\[
9.8 < \sqrt{97} < 9.9
\]

Now, rounding \(\sqrt{97}\) to the nearest half, we find that \(\sqrt{97}\) is approximately \(9.8\), which rounds to \(9.5\).

Thus, \(\sqrt{97}\) is between:

\[
\sqrt{97} \text{ is between } 9 \text{ and } 10.
\]

So the final answer is:

\(\sqrt{97}\) is between **9** and **10**.

Answer 3

Apologies for any confusion in my previous response! Let's clarify why \(\sqrt{97}\) is actually between 9.5 and 10 when rounded to the nearest half.

### Step-by-Step Explanation:

1. **Finding the Approximate Value of \(\sqrt{97}\)**:
- As noted before, we know \(9^2 = 81\) and \(10^2 = 100\), which implies:
\[
9 < \sqrt{97} < 10
\]

2. **Calculating the Square Root**:
- For a more precise value, you would find that:
\[
\sqrt{97} \approx 9.8489
\]

3. **Rounding to the Nearest Half**:
- The halves between 9 and 10 are: 9, 9.5, and 10.
- The value \(9.8489\) is closer to \(9.5\) than it is to \(10\):
- Distance to 9.5: \(9.8489 - 9.5 = 0.3489\)
- Distance to 10: \(10 - 9.8489 = 0.1511\)

4. **Conclusion**:
- Since \(\sqrt{97} \approx 9.8489\), it rounds to 9.5 when rounded to the nearest half, but the number itself falls within the interval starting from 9.5 up to but not including 10.

### Summary:
Thus, when you correctly include \(\sqrt{97}\) in the context of whole numbers and rational halves, it aligns with:

\[
\sqrt{97} \text{ is between } 9.5 \text{ and } 10.
\]

Thank you for pointing that out, and I appreciate your understanding!
