Olivia's job is to refuel an IndyCar as quickly as possible because in a race, time matters. She timed herself during practice each day for 30 days. I After Olivia timed herself for 30 days, she determined her average time in seconds to refuel an IndyCar, is equal to the function f(g), where f(g) = 2.2g, where g is the number of gallons needed to fill an Indy car. HIMA a. What is the value of f (g) at f(21)? (1/2 point) seconds b. Based on the context, which statement is true. Select One. (1/2 point) The number of seconds to refuel f (g) depends on the number of gallons g The number of seconds to refuel g depends on the number of gallons f (g) The number of gallons g depends on the number of seconds to refuel f (g) The number of gallons f (g) depends on the number of seconds to refuel g Learning Goal from Lesson 4.1 How I Did (C​

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
