___________________ Show how you figured it out.

2. The next exit is 3.4 miles ahead. How much time will it take for the car to reach the exit?

___________________________ Show how you figured it out.

A traffic officer is monitoring traffic on a windy section of road that has a speed limit of 55 miles per hour. A car speeds past the officer and the radar gun indicates the car is traveling 68 miles per hour.

Steph and Draymond like to take different trips traveling across their hometown on foot. 1. Draymond was gone for 6 hours. He walked half the time and then rested for the same

amount of time. Sketch a graph to show the distance – time graph of his journey.

2. Steph traveled a distance of 20 miles. He ran at a fast pace for half the distance and then

walked at a pace twice as slow as he ran for the remaining half of the distance. Sketch a graph to show the distance – time graph of his journey.

You are a teacher’s assistant for the Athletic Trainer at your school. The training room needs cleaning up because of all the new training equipment and supplies your Athletic Trainer has acquired. You need to buy some cabinets for the room. You look at two different brands. You know that the Trainer’s Closet cabinet costs $10 per cabinet. The Medicine Chest cabinet costs $20 per cabinet. You have been given $140 for this purchase, though you don't have to spend that much. Your job is to research the numbers of each type of cabinets you should buy, in order to maximize storage volume and stay under the total cost and space restrictions. Let x be the number of Trainer’s Closet cabinets. 1. Write an expression to show what it would cost to buy x number of Trainer’s Closet

cabinets. _______________________________________________________________________ Let y be the number of Medicine Chest cabinets.

2. Write an inequality to show that the amount you can spend on the two types of cabinets

is less than or equal to the total money you have for this purchase.

_______________________________________________________________________ 3. Sketch a graph of the inequality of the amount you spend on the two cabinets.

Now that you have an equation for the total costs of the two types of cabinets, you are considering the amount of space needed in your training room for the cabinets. You would like the cabinets to fit in an area of no more than 72 square feet. The Trainer’s Closet cabinet requires six square feet of floor space. The Medicine Chest cabinet requires eight square feet of floor space. 4. Write an inequality to represent the space the two cabinets would require.

____________________________________________________________________

5. On the same axis, sketch a graph of the inequality that represents the space the two

types of cabinets would require.

6. What are the coordinates of the intersection of those two lines? _________________

Show how you figured it out. Remember, the goal of your job is to maximize the volume of storage space and stay under the total cost and space restrictions. The Trainer’s Closet cabinet holds eight cubic feet of sports medicine supplies. The Medicine Chest cabinet holds twelve cubic feet of sports medicine supplies. 7. If you selected the optimum numbers of each type of cabinet for the training room,

what would the total storage volume of the cabinets be? __________________ cubic feet

Show how you figured it out.

Janice and Janet are making sense of algebraic expressions with exponents. Janice draws the following figure, comprised of four small rectangles inside a big rectangle. Janice said, “The length of this big rectangle is x + 3 and the width is x + 2.” She asked Janet, “What is the perimeter of the big rectangle?” 1. What answer should Janet give? ________________________________ units Janet then asks Janice, “What is the area of the big rectangle?” 2. What answer should Janice give? _____________________________ sq. units

Show how you figured it out.

Janice now asks a new question, “A different big rectangle has an area of x2 + 7x + 12. What does it look like?” 3. Draw this new big rectangle and label the dimensions of the four smaller rectangles

contained in the big rectangle.

Amari is studying three different microorganisms in biology. Amari has put each microorganism on a separate Petri dish labeled A, B and C. Each day he looks through a microscope and counts the number of microorganisms on each dish. He made a table of the numbers of microorganisms he counts on each dish.

Microorganisms Dish/Day Day 1 Day 2 Day 3 Day 4 Dish A 6 6 6 6 Dish B 1 7 13 19 Dish C 1 3 6 10

Assume the microorganisms continue to grow at the same rate from day to day.

1. How many microorganisms will be on Dish A on Day 5?

_______________________ microorganisms
