Before beginning this exercise, the group needs to read and solve Exercise 40.
a A political group is planning a demonstration on 95lh Street between 113th Place and 117th Court for 5 p.m. Wednesday. The problem becomes one of minimizing traffic flow on 95lh Street (between 113th and 117ih) without causing traffic tie-ups on other streets. One possible solution is to close off traffic on 95lb Street between 113th and 117th (let
). What can group members conclude about
under these conditions?
b. Working with a matrix allows us to simplify the problem caused by the political demonstration, but it did not actually solve the problem. There are an infinite number of solutions; each value of

- At the Pizza Dude restaurant, a 12-in. pizza costs 5.40 to make, and the manager wants to make at least 4.80 from the sale of each pizza. If the pizza will be sold by the slice and each pizza is cut into 6 pieces, what is the minimum charge per slice?arrow_forwardRon and Tim both work as landscapers during the summer months. Due to the heat, thescheduled start time is 7am. Typically though, the crew leader is late and most days they do notactually start work until 7:30 or 8am. Ron likes to catch a quick nap while he waits, however Timusually will pick up a broom or clean to pass the time. What time would his “compensabletime” begin for Ron and Tim (assume that 7:45 is the average start timarrow_forwardA tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…arrow_forward
- A bank heist occurs. The robbers flee the bank at 60 km/h due south. As they are leaving, cops that are 20 km east of the bank begin driving west towards the bank at 80 km/h. At what time before the cops reach the bank will they be closest to the robbers?arrow_forwardTwo people are driving east on the 401 highway in the same direction. One driver is starting in London, Ontario, and is driving at a speed of 135km/h. The other driver is starting in Kitchener, Ontario and is driving at a speed of 108km/h. At what distace and time will the two drivers meet on the highway if the driver from London started driving 30 minutes before the driver in Kitchener? (You may need to search up some distances up on your device, like the distance between Kitchener and London Ontario) Use whatever techniques or technology, you need to solve the problem, but a complete, correct, and algebraic solution will give you the best grade.arrow_forwardMy teacher said to use a chart to solve this problem.arrow_forward

- Please answer this questionarrow_forwardPlease show steps and answer all questions.arrow_forward9) Erin goes for her daily run. The elevation changes, so she can run some sections faster than others. She also gets tired and walks at times. In other words her speed is not always increasing. She passes several speed check areas that are set up to control vehicular speeding, so she can see how fast she is moving at various times. Based on the information in the chart, estimate the shortest and longest distances that she could have run. You can use the other tables to organize your work.
