2. Each representation below gives the total cost, C, for an order of food, n. n can represent the number of medium pizzas with no toppings, the number of toppings, or the number of orders of breadsticks. A medium pizza with no toppings costs $7, toppings cost 75C each, and an order of breadsticks costs $2. Fill in the blanks to match each algebraic rule with the correct description and graph. C- 2n Description: Graph: Graphs Descriptions L Cost for n medium pizzas without a delivery charge C-7+ 0.75n Description: Graph: il. Cost for n medium pizzas with a $5 delivery charge C-5+ 7n Description: Graph: . Cost for a single medium pizza with a toppings C- 6 + 2n Description: Graph: w.

The following table shows the hot dogs bought from a street vendor over the course of eight days​ ("Demand"). Also shown is the temperature for each day in degrees Celsius. Complete parts a and b below.

Daily High Temp. The histograms describe the high temperatures in a certain city on each day of one month. The histogram on the left uses class widths of 3°F and the histogram on the right uses class widths of 6°F. Assume that temperature is measured and recorded as whole number values so that the first class would be 64°F-66°F when using a class width of 3°F. Complete parts (a) through (c) below. Daily High Temp. 64 70 76 82 88 94 Degrees Farenheit 64 70 76 82 88 94 Degrees Fareniheit a. During this month, there tends to be two types of weather. The city experiences either cool, foggy days or hot, sunny days. Which of the two histograms better reflects this? O A. The histogram with class widths of 6°F, because the histogram has larger class widths. O B. The histogram with class widths of 6°F, because there are no gaps in the histogram. OC. The histogram with class widths of 3°F, because the two distinct groups of data are separated by a gap in the histogram. O D. The histogram with…

is the * 3. Here are some statistics on a large passenger airplane: The length is 239 feet, the wingspan is 262 feet, the fuel capacity is 81,890 gallons, and the range is 8000 nautical miles. a. Compare the length and wingspan of the airplane additively, in a sentence. Then compare them multiplicatively, in a sentence. b. Approximately how many gallons of fuel does the airplane use per nautical mile? c. Make a graph of the number of miles traveled and the number of gallons of fuel used. Plan the scales for your axes ahead of time. d. What is the slope of the line in part (c)? ndle
