Question 1: Two conversions (2 points)
- Convert \(3.25\text{ mi}\) to feet. (1 point)
- Convert \(252\text{ min}\) to hours. (1 point)
Question 2: Speed in feet per second (3 points)
A race car travels at \(55\text{ mi/h}\). Write the conversion to feet per second as a product of fractions and find the speed to the nearest tenth. (3 points)
Question 3: Units of a quotient (2 points)
A truck uses fuel at a constant rate. It travels \(60\text{ mi/h}\) and gets \(30\text{ mi/gal}\). Find the quotient \(\frac{60\text{ mi/h}}{30\text{ mi/gal}}\), including its units, and explain what it measures. (2 points)
Question 4: Filling a container (3 points)
A container is a rectangular box \(3\text{ ft}\) long, \(2\text{ ft}\) wide and \(1.5\text{ ft}\) tall. A hose fills it at \(8\text{ gal/min}\), and \(1\text{ ft}^{3}\) holds \(7.48\) gallons.
- Find the volume in cubic feet. (1 point)
- Find the capacity in gallons. (1 point)
- Find the filling time in minutes, to the nearest tenth. (1 point)
Question 5: Scale of a graph (3 points)
The graph shows enrollment at Lincoln High School, in students, over five school years (Year 1 is 2020).
- Find the increase from Year 1 to Year 5. (1 point)
- Find what percent of the graph’s vertical axis height this increase covers. (1 point)
- Find what percent it would cover if the vertical axis ran from 0 to 1250, and state which graph makes the change look larger. (1 point)
Question 6: Defining a quantity (2 points)
A courier charges \(\$20\) plus \(\$0.50\) per mile. Define variables with units and write an equation for the cost (1 point), then find the cost of an \(18\)-mile delivery (1 point).
Question 7: Accuracy of a poster (3 points)
A rectangular poster measures \(24.5\text{ in}\) by \(18.2\text{ in}\), each measured to the nearest tenth.
- Find the area and report it with an appropriate level of accuracy. (2 points)
- Write an inequality for the actual width \(w\). (1 point)
Question 8: Trip planning (2 points)
Sofia’s car gets \(25\text{ mi/gal}\) and gas costs \(\$4.00\) per gallon. Find the gas needed for a \(350\text{-mile}\) trip, the cost of that gas, and the cost per mile. (2 points)
