Calculate the volume of 55 grams of benzene, given that the density of benzene is $0.879 \mathrm{g} \cdot \mathrm{cm}^{-3}$.

Movie theater popcorn is sold in notoriously large quantities. The smallest size popcorn usually contains at least 2 servings of popcorn. And, when you're eating all of that popcorn, you have to get a drink! Compare the prices for various sizes of popcorn sold at the local movie theater. Mega Bag (32 oz) $10.24 Giant Bag (24 oz)$6.00 Medium Bag ($4.48) Kid's Bag (8 oz)$2.40 a. What is the unit rate price per ounce for each bag of popcorn? b. What size popcorn is the best buy? Explain your reasoning.

Compare the mean absolute deviations and the interquartile ranges. a. What does each measure tell you about the data set? b. How are they the same? How are they different?

You learned to solve addition equations by first reasoning with bar models and then with inverse operations. Now that you have solved multiplication equations by reasoning with bar models, how do you think that you can solve these equations without using the bar models?

Consider the combined function T(x) = f(x) + g(x) + h(x), where $f(x)=2^{x}$, g(x) = 2x, and $h(x)=x^{2}$. a) How is this function related to the total tiles pattern in the Investigate at the beginning of this section? b) Graph f(x), g(x), and h(x) on the same set of axes. Use colours or different line styles to easily distinguish the curves. c) Graph the combined function T(x). d) Adjust the viewing window to explore what happens as the x- and y-values are increased by large quantities. The function T(x) appears to converge with one of the three component functions. Which one is it? e) Explain the result in part d) by considering the rates of change of the component functions.
