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.

the answer was actually 9.5 and 10 but why

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!
