Question
Using a number line, what whole number and rational number to the nearest half is 97−−√
between?(1 point)

1 answer

To determine the whole number and the rational number (to the nearest half) that \(\sqrt{97}\) falls between, we can start by estimating the value of \(\sqrt{97}\).

  1. Identify the perfect squares around 97:
    • \(9^2 = 81\)
    • \(10^2 = 100\)

From this, we know that: \[ 9 < \sqrt{97} < 10 \]

  1. Finding a more precise estimate:
    • We can start calculating some squares to find a value closer to 97.
    • \(9.5^2 = 90.25\)
    • \(9.7^2 = 94.09\)
    • \(9.8^2 = 96.04\)
    • \(9.9^2 = 98.01\)

Since \(9.8^2\) is just below 97 and \(9.9^2\) is just above 97, we can say: \[ 9.8 < \sqrt{97} < 9.9 \]

  1. Rational number to the nearest half:
    • The nearest halves around \(9.8\) would be \(9.5\) and \(10.0\).
    • Since \(\sqrt{97} \approx 9.848\), it rounds to \(9.5\).

In conclusion, \(\sqrt{97}\) is between the whole number \(9\) and the rational number \(9.5\) (to the nearest half).

So, your answer is that \(\sqrt{97}\) is between 9 and 9.5.
