Study the example showing how to find the unit rate. then solve problems 1-7. example a bus driver made 100 stops on his route in 5 days. the double number line shows the relationship between the number of stops and the number of days. stops 0 20 40 60 80 100 120 140 150 days 0 1 2 3 4 5 6 7 8 in the diagram, 100 and 5 represent the ratio of 100 stops to 5 days. you can write a multiplication equation to show how 5 days and 100 stops are related. 5 x 20 = 100 look at the corresponding pairs of numbers on the number lines. write a multiplication equation to show how 3 days and 60 stops are related. repeat for two other corresponding pairs of numbers. 2 what is the relationship between the number of stops and each corresponding number of days? 3 what is the rate of stops per day? what is the unit rate? vocabulary rate a ratio that compares the first quantity to only one of the second quantity. unit rate the number in a rate that is being compared to 1. rate: unit rate:
Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
