The approximate value of √105 is approximately 10.24. To find the whole number and nearest rational number to the nearest half, we determine that √105 is between 10 and 11. The rational number to the nearest half would be between 10.5 and 11. Therefore, the correct response is "between 10.5 and 11".

To compare and approximate the values of √48 and √36, we can simplify these square roots to their rational approximations.
√48 can be simplified to √(16 * 3), which is equal to 4√3.
√36 is equal to 6.
Therefore, the correct answer is "48−−√>36−−√" since 4√3 is greater than 6.
√48 can be simplified to √(16 * 3), which is equal to 4√3.
√36 is equal to 6.
Therefore, the correct answer is "48−−√>36−−√" since 4√3 is greater than 6.

Using a number line, what is the approximate number value of 103−−−√? Provide your answer in decimal form, rounded to the nearest hundredth.(1 point)
103−−−√ is approximately
103−−−√ is approximately
Using a calculator, we can find that the approximate value of √103 is approximately 10.15. Therefore, rounding to the nearest hundredth, 103−−−√ is approximately 10.15.
Using a number line, what whole number and rational number to the nearest half is 10−−√ between?(1 point)
10−−√ is between
and
10−−√ is between
and
To find the whole number and rational number to the nearest half that 10−−√ is between, we can approximate the value of √10.
√10 is approximately 3.16.
Since 3 is the largest whole number less than 3.16 and 3.5 is the nearest half greater than 3.16, the whole number and rational number to the nearest half that 10−−√ is between are 3 and 3.5.
Therefore, 10−−√ is between 3 and 3.5.
√10 is approximately 3.16.
Since 3 is the largest whole number less than 3.16 and 3.5 is the nearest half greater than 3.16, the whole number and rational number to the nearest half that 10−−√ is between are 3 and 3.5.
Therefore, 10−−√ is between 3 and 3.5.
