Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. I evaluated the formula \(d=\sqrt{1.5 h}\) for a value of \(h\) that resulted in a rational number for \(d\).
From here on, each exercise set will contain three review exercises. It is essential to review previously covered topics to improve your understanding of the topics and to help maintain your mastery of the material. If you are not certain how to solve a review exercise, turn to the section and the worked example given in parentheses at the end of each exercise. Determine whether this inequality is true or false: \(19 \geq-18 .\) (Section 1.3, Example 7)
Use your calculator to attempt to find the quotient of \(-3\) and \(0 .\) Describe what happens. Does the same thing occur when finding the quotient of 0 and \(-3 ?\) Explain the difference. Finally, what happens when you enter the quotient of \(\overline{0 \text { and itself? }}\)
In Exercises \(117-118\), use the formula \(C=\frac{5}{4}(F-32)\) to express each Fahrenheit temperature, \(F,\) as its equivalent Celsius temperature, \(C\). $$-22^{\circ} \mathrm{F}$$
Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. I saved money by buying a computer for \(\frac{3}{2}\) of its original price.
