Answer:

Instructions

First, you need to come up with an activity. If you are having trouble thinking of what to do, here are some ideas:

• How many jumping jacks can you do in a minute?

• How many times can you write your full address in a minute?

• How many points can you score in a game in three minutes?

• How many pages of a book can you read in four minutes?

• How far can you walk in five minutes?

Feel free to be creative or even to come up with an activity you think your teacher has not seen before.

Now that you have decided what your activity is going to be, it’s time to get started.

Part 1: Record Information

Spend a short amount of time (one to five minutes) doing your activity. Answer the following questions:

• What was the activity? How many jumping jacks can you do in a minute

1. How long did you spend doing your activity? 15min

2. How much of the activity did you complete in the time period? (Example: I did 24 sit-ups in one minute.) I did 24 jumping jacks in 1min.

3. Which of these variables is your dependent variable?

4. Which one is the independent variable?

5. Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio language can help.)

Part 2: Prepare a Table

Assuming that you could complete the activity at the same rate over different time periods, how much of the activity could you complete in two minutes, three minutes, four minutes, and five minutes? (Note: If you spent two minutes doing your activity, then you should edit the table below and use multiples of 2 up to 10).

You may use the table below for your variables.

Time (minutes)

0 0

1 24

2 26

3 30

4 37

5 40

Part 3: Prepare a Graph

Create a graph to show your relationship. Make sure you include all the parts for a graph and show the data clearly.

When I do jumping jakes its 24 a minute witch should be something someone does per min if you do it fast it would probably go down to 20 or 18 if you do it a little slower it would go up too 26 at least

Part 4: Write an Equation

Based on your recorded values, write an equation that represents the relationship between the time you spent doing the activity and the amount of the activity you completed. Make sure to define your variables.

Follow-up questions

6. If you were able to maintain this rate of your activity for 12 minutes, how much of the activity would you be able to complete?

7. How long would it take you to reach 100 for the number of times you did your activity?

8. Which representation do you believe is the best way to share this information with someone else? This is your opinion. No answer is right or wrong.

(Question 1 is worth 1 point; questions 2 and 3 are worth 2 points each.)

What is 40°F minus 32°divided by 1.8

grigory [225]

40 degrees - 32 degrees = 8 degrees

8 degrees divided by 1.8 = 4.4444444 degrees

to divide add a decimal point and zero to the 8 and move the decimal point 1 place to the right in 1.8 and in 8.0 and divide from there

Movie tickets and film streaming services are substitutes. If the price of film streaming increases, what happens in the market

tatuchka [14]

Answer:

D. The demand curve shifts to the right.

Step-by-step explanation:

Movie tickets and film streaming services are substitutes, so an increase in the price of film streaming will cause an increase in the demand for movie tickets. Thus, at any given price, the demand curve of movie tickets shifts to the right, for example from demand A to demand B or demand C. as in the attached figure.

Andy has a snowball (a perfect sphere) with the radius of 3 cm. He wanted the snowball to be bigger, so he spent four seconds pa

BigorU [14]

Answer:

Ratio = $\frac{64}{27}$

Step-by-step explanation:

Volume of Sphere is given by the formula:

$V=\frac{4}{3} \pi r^3$

Where

V is the volume

and

r is the radius

Original Volume, given r = 3, would be:

$V=\frac{4}{3} \pi r^3\\V=\frac{4}{3} \pi (3)^3\\V=\frac{4}{3}\pi (27)\\V=36\pi$

Increased snowball volume:

Radius increased 0.25 per second, he spent 4 seconds, so radius increase:

0.25 * 4 = 1 cm

New radius = 3 + 1 = 4 cm

New Volume would be:

$V=\frac{4}{3} \pi r^3\\V=\frac{4}{3} \pi (4)^3\\V=\frac{4}{3}\pi(64)\\V=\frac{256\pi}{3}$

Ratio of New Volume to Original would be:

$Ratio=\frac{\frac{256\pi}{3}}{36\pi}=\frac{256\pi}{3}*\frac{1}{36\pi}=\frac{64}{27}$

This is the ratio for current volume to original volume.

Answer:

lower left

Step-by-step explanation:

We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.

x-coefficient : y-coefficient : constant

= 2 : 1 : -15 . . . . . in the given equation

2 : -2 : 30 = 1 : -1 : 15 . . . upper left — not the same

-4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same

-4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation

-4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same
