**Write an expression for the sequence of operations:**

**Add 3 to x, subtract the result from 1, then double what you have.****Add 3 to x, double what you have, then subtract 1 from the result.**

**HINT: Parenthesis force you to do operations before other operations!**

**Mr. Mendelson wants to know how his P.E. classes are improving in the number of push-ups they can do. This graph shows the number of push-ups each student in his 1st period class was able to do last month and this month.**

**How much did the mean number of push-ups increase from last month to this month?**

**120 students went to Fun Park for the day. Two-fifths of the group waited in line for the Super Looper. The rest of the group waited in line for the Jet Coaster. A single ride on the Super Looper lasts 10 min and can take 8 people at a time. A single ride on the Jet Coaster lasts 8 min and can take 12 people. Will the group riding the Super Looper finish first or will the group riding the Jet Coaster finish first?**

**Don’t forget to explain how you know your solution is correct!!!!!**

**While grading student papers, I noticed that while computing the product of 4.5 and 1.2, this student carefully lined up the decimals and then multiplied, bringing the decimal point straight down and reporting a product of 54.0.**

**Is this solution correct or incorrect? Defend your choice either way with a DETAILED explanation as to why this student was correct or incorrect in solving this math problem!**

**If x<y, which of the following best describes the values of:**

**It is always greater than 1**

**It is always less than 1****It is always 1****It varies depending on the values of x and y**

**DON’T JUST PICK AN ANSWER!!! You need 3 examples of your own. Pick examples for x and y (they must be different because the variables are different), plug them in and see what happens. **

**HINT: The values you pick can be whole numbers, mixed numbers, integers, fractions, a mix, ect…**

**A “conjecture” is an educated guess. **I noticed something when I divided a whole number and a fraction so I’m making a “conjecture”. Your job is to see if my conjecture is **always true, sometimes ****true, **or **never true.** You will do this by checking my work and then positing your own 3 examples. If you cannot find an example that disproves my conjecture you should assume it is always true. If you can find even one example that disproves my conjecture you would conclude that my conjecture is sometimes true. In this example, we know that “never true” isn’t an option because my examples are true! Here we go:

I took 60 and divided it by 1/2 (**not 2**) and my calculator said the answer was 120.

60 ÷ (0.5) = 120

I took 10 and divided it by 1/4 (**not 4**) and my calculator said the answer was 40.

10 ÷ (0.25) = 40

I took 75 and divided it by 1/10 (**not 10**) and my calculator said the answer was 750.

75 ÷ (0.1) = 750

**My conjecture: When you divide a whole number by a fraction the answer is more than you started with. **Is this always true or sometimes true? In order to pick “sometimes true” you have to come up with an example that disproves my conjecture.

**Your heart pumps about 5 quarts of blood through its chambers every 60 seconds. A swimming pool (20ft x 60ft) will hold about 65,000 gallons of water.**

**How many weeks would it take your heart to pump that much blood?**

**You can find a conversion table HERE!**

**In Reno, Netflix earned $5,393.25 in subscriptions during July. January subscriptions are expected to double that amount. If a Netflix subscription is $7.99, how many subscriptions are expected in January?**

**Remember that you will need to SHOW and EXPLAIN how you solved your problem. DO NOT just type an answer in!!**

**It takes a lot of work to keep Disneyland’s two parks looking top notch. Some of that** **work is making sure that all the equipment is freshly painted and looking its best. When it comes time to paint the Ferris Wheel, Disneyland maintenance crews need to use a little math to get the job done. The diameter of the Ferris Wheel is 160 feet. They need to paint both of the outside rails of wheel red. How many feet total of red paint will they be painting? Explain how you found your solution.**
