To determine where \( \sqrt{58} \) lies on a number line, we first need to calculate \( \sqrt{58} \).

To approximate \( \sqrt{58} \):

  • We know that \( 7^2 = 49 \) and \( 8^2 = 64 \).
  • Thus, \( 7 < \sqrt{58} < 8 \).

For a more accurate approximation, we can calculate:

  • \( 7.5^2 = 56.25 \)
  • \( 7.6^2 = 57.76 \)
  • \( 7.7^2 = 59.29 \)

Since \( 56.25 < 58 < 59.29 \), we know that \( 7.5 < \sqrt{58} < 7.7 \).

To estimate \( \sqrt{58} \) to the nearest half, we can see that:

  • Since \( 7.5 < \sqrt{58} < 7.6 \), we round \( \sqrt{58} \) to approximately \( 7.6 \).

Checking for the nearest half, \( 7.5 \) and \( 8 \) would be the rational numbers around it.

Thus, \( \sqrt{58} \) is between \( 7.5 \) and \( 8 \).

The correct response is: between 7.5 and 8.
