Simplify \(\frac{10}{\sqrt{32}}\) A. \(\frac{5}{4}\sqrt{2}\) B. \(\frac{4}{5}\sqrt{2}\) C. \(\frac{5}{16}\sqrt{2}\) D. \(\frac{16}{5}\sqrt{2}\)
Show Content
Detailed Solution\(\frac{10}{\sqrt{32}}=\frac{10}{\sqrt{16\times 2}} = \frac{10}{4\sqrt{2}}\\\frac{10\times \sqrt{2}}{4\sqrt{2}\times\sqrt{2}}=\frac{10\sqrt{2}}{4\times 2}= \frac{5}{4}\sqrt{2}\) |

What fraction must be subtracted from the sum of \(2\frac{1}{6}\) and \(2\frac{7}{12}\) to give \(3\frac{1}{4}\)? A. \(\frac{1}{3}\) B. \(\frac{1}{2}\) C. \(1\frac{1}{6}\) D. \(1\frac{1}{2}\)
Show Content
Detailed Solution\(2\frac{1}{6} + 2\frac{7}{12}\)= \(\frac{13}{6} + \frac{31}{12}\) = \(\frac{26 + 31}{12}\) = \(\frac{57}{12} = \frac{19}{4}\) \(\frac{19}{4} - 3\frac{1}{4}\) = \(\frac{19}{4} - \frac{13}{4}\) = \(\frac{6}{4}\) = \(1\frac{1}{2}\) |

Simplify \(\left(\frac{16}{81}\right)^{-\frac{3}{4}}\times \sqrt{\frac{100}{81}}\) A. \(\frac{80}{243}\) B. \(\frac{1}{64}\) C. \(\frac{25}{6}\) D. \(\frac{15}{4}\)
Show Content
Detailed Solution\(\left(\frac{16}{81}\right)^{-\frac{3}{4}}\times \sqrt{\frac{100}{81}}\\\frac{1}{\left(\sqrt[4]{\frac{16}{81}}\right)^3}\times \frac{10}{9}=\frac{1}{\left(\frac{2}{3}\right)^3}\times\frac{10}{9}\\ =\frac{27}{8}\times \frac{10}{9}=\frac{15}{4}\) |

If \(104_x = 68\), find the value of x A. 5 B. 7 C. 8 D. 9
Show Content
Detailed Solution\(104_x = 68\\1 \times x^2 + 0 \times x + 4 \times x^0 = 68\\ x^2 = 68 - 4; x^2 = 64\\ x = \sqrt{64}=8\) |

The ages of three men are in the ratio 3:4:5. If the difference between the ages of the oldest and youngest is 18 years, find the sum of the ages of the three men A. 45 years B. 72 years C. 108 years D. 216 years
Show Content
Detailed SolutionGiven that the ages are in the ratio 3: 4: 5.Let the sum of their ages be t. \(\therefore\) The youngest age = \(\frac{3}{12} t\) The eldest age = \(\frac{5}{12} t\) \(\implies \frac{5}{12} t - \frac{3}{12} t = 18\) \(\frac{2t}{12} = 18 \implies t = \frac{18 \times 12}{2}\) t = 108 years. The sum of their ages = 108 years. |
