Consecutive odd integers are odd integers listed in order such as \(5,7,\) and 9 . Find three consecutive odd integers whose sum is 111 . Are there three consecutive odd integers whose sum is \(1111 ?\) Explain.
Graph the numbers on a number line. Then write two inequalities that compare the two numbers. $$-0.2 \text { and }-0.21$$
Round to the nearest tenth. A total of 382 kilograms of lunar samples (rocks, dust, and so on) were collected during the six Apollo moon landings between 1969 and 1972. About \(7.5 \%\) of the lunar samples (by weight) have been analyzed and then returned for storage in the Return Sample Vault at NASA's Johnson Space Center. What is the combined weight of the samples in this vault?
Graph the numbers on a number line. Then write two inequalities that compare the two numbers. $$\frac{3}{4} \text { and }-\frac{5}{6}$$
Use the following information. You open a snack stand at a fair. The income and expenses (in dollars) for selling each type of food are shown in the matrices. \(\begin{array}{ccccccc}\text { Day 1 } & \text { Income } & \text { Expenses } & \text { Day 2 } & \text { Income } & \text { Expenses } \\ \text { Hamburgers } & 72 & 14 & \text { Hamburgers } & 62 & 10 \\ \text { Hot dogs } & 85 & 18 & \text { Hot dogs } & 52 & 11 \\ \text { Tacos } & 46 & 19 & \text { Tacos } & 72 & 26\end{array}\) Which type of food had the largest profit?
