Using a number line, what whole number and rational number to the nearest half is [tex]\sqrt{105}[/tex] between?

A. between 10 and 10.5
B. between 11 and 11.5
C. between 10.5 and 11
D. between 9.5 and 10



Answer :

To determine the whole number and rational number to the nearest half that [tex]\(\sqrt{105}\)[/tex] is between, we first need to find an approximation of [tex]\(\sqrt{105}\)[/tex].

Given that [tex]\(\sqrt{105} \approx 10.246950765959598\)[/tex], we can place this value on a number line.

Here are the major steps to identify the correct interval:

1. Whole Numbers: Look for the nearest whole numbers between which [tex]\(\sqrt{105}\)[/tex] lies.
- The nearest whole numbers are 10 and 11, since [tex]\(10 < 10.246950765959598 < 11\)[/tex].

2. Rational Numbers to the Nearest Half: Identify the rational numbers to the nearest half that bound [tex]\(\sqrt{105}\)[/tex].
- Evaluating the halves, we have 10.0, 10.5, 11.0, etc.
- Since [tex]\(10 < 10.246950765959598 < 10.5\)[/tex] and [tex]\(10.246950765959598 < 11\)[/tex], we compare the value closer to the halves.
- Here, [tex]\(10.246950765959598\)[/tex] is greater than 10 but less than 10.5 and less than 11.

Given that [tex]\(\sqrt{105}\)[/tex] lies between 10.5 and 11:

The answer is:

Between 10.5 and 11.
