If \(x=\frac{\sqrt{81}}{4}\), what is (x) equal to on the number line?
A. \( \frac{9}{4} \)
\( \sqrt{81}=9 \), इसलिए \(x=\frac{9}{4}\) है। पहले वर्गमूल निकालें फिर भाग करें। / \( \sqrt{81}=9 \), so \(x=\frac{9}{4}\). Find the square root first and then divide.

Which statement is correct for \( \sqrt{5} \) and (2.24) on the number line?
A. \( \sqrt{5}<2.24 \)
\( \sqrt{5}\approx2.236 \) है और यह (2.24) से थोड़ा छोटा है। निकट दशमलवों में अधिक स्थानों तक तुलना करें। / \( \sqrt{5}\approx2.236 \), which is slightly less than (2.24). Compare close decimals to more places.

A. \( -1-\sqrt{6} \)
बाईं ओर जाने पर दूरी घटाई जाती है। इसलिए निर्देशांक \( -1-\sqrt{6} \) होगा। / Moving left means subtracting the distance. Therefore the coordinate is \( -1-\sqrt{6} \).

Which point is exactly midway between \( \frac{2}{5} \) and \( \frac{3}{5} \) on the number line?
A. \( \frac{1}{2} \)
मध्य बिंदु \( \frac{\frac{2}{5}+\frac{3}{5}}{2}=\frac{1}{2} \) है। मध्य के लिए औसत लें। / The midpoint is \( \frac{\frac{2}{5}+\frac{3}{5}}{2}=\frac{1}{2} \). Use the average for the midpoint.

Which value lies between \( -\sqrt{3} \) and \( -\frac{5}{3} \) on the number line?
A. ( -1.70 )
\( -\sqrt{3}\approx-1.732 \) और \( -\frac{5}{3}\approx-1.667 \) है। इसलिए (-1.70) इनके बीच है। / \( -\sqrt{3}\approx-1.732 \) and \( -\frac{5}{3}\approx-1.667 \). Therefore (-1.70) lies between them.

If \(a=\sqrt{27}-\sqrt{12}\), what is the simplified form of (a) on the number line?
A. \( \sqrt{3} \)
\( \sqrt{27}=3\sqrt{3} \) और \( \sqrt{12}=2\sqrt{3} \) इसलिए अंतर \( \sqrt{3} \) है। समान मूलों को घटाएँ। / \( \sqrt{27}=3\sqrt{3} \) and \( \sqrt{12}=2\sqrt{3} \), so the difference is \( \sqrt{3} \). Subtract like radicals.

What type of number is \(0.2727727772\ldots\) on the number line?
A. अपरिमेय संख्याIrrational number
यह दशमलव असांत और अनावर्ती है। इसलिए यह संख्या रेखा पर अपरिमेय संख्या है। / This decimal is non-terminating and non-repeating. Hence it is an irrational number on the number line.

A. (42)
\(6.4^2=40.96\) और \(6.5^2=42.25\), इसलिए (n) इनके बीच होना चाहिए। (42) सही सीमा में है। / \(6.4^2=40.96\) and \(6.5^2=42.25\), so (n) must lie between them. (42) is in the correct range.

Between which two integers is \( -\frac{17}{5} \) located on the number line?
A. ( -4 ) और ( -3 )( -4 ) and ( -3 )
\( -\frac{17}{5}=-3.4 \) है। यह (-4) और (-3) के बीच आता है। / \( -\frac{17}{5}=-3.4 \). It lies between (-4) and (-3).

If (A=-2.75) and (B=1.25) on the number line, what is the midpoint of (AB)?
A. ( -0.75 )
मध्य बिंदु \( \frac{-2.75+1.25}{2}=-0.75 \) है। मध्य बिंदु निकालने में औसत लें। / The midpoint is \( \frac{-2.75+1.25}{2}=-0.75 \). Take the average to find a midpoint.
