Carlo's Pythagorean Relationship

1. The relationship between the lengths of the side of a right triangle. The sum of the areas of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotenuse.

2. Solve for the missing side length.

3.Is this a right triangle??

Not A perfect Triangle.

4. Estimate the square root of each number, to one decimal place. Check your answer with calculator.

A) 72

8.5 x 8.5= 72,25 close enough to 72.

B) 103

10.1 x 10.1= 102.01

C) 55

7.4 x 7.4= 54.76

9)What are all possible whole number that have square root between 4 and 5.

1. R C E E T N P

Percent means out of 100.

2. C R A T F I O L N A

A fraction percent is a percent that include portion if 1%

3 M C N O B D E I

Percents that are added together are combined percents.

6.A store discounted items by 50% off the original price one week. The following week an additional 10% was taken off the already reduced price. The regular priceof a CD player was $85.00. What is the reduced price in the second week?

First Week:

50/100= 0.5x85.00=$42.50

85-42.50= $42.5

$42.50

Second Week:

0.1x42.50=$4.25

42.50-4.25= $38.25

Carlo's Pay It Forward

Part 2

What was your Pay It Forward act of kindness?

My friend Gielh Concepcion and I cleaned my relatives yard.

Why did you choose this activity?

We chose this activity because we wanted to clean my cousins front yard and keep the community clean.

Me and Gielh help my relatives front yard.

What did you do?

We raked leaves .

When did you do you act of kindness?

We did our act of kindness at the weekend.

Part 3

How did your act of kindness go?

Our act of kindness wen't good because it was fun and exciting to keep the community clean.

What Happened?

When we were cleaning up my relative front yard it was really happy , they were proud of us.

How did you feel?

Gielh and I felt good because we helped my relatives.

How did the person or people react?

They were happy because we help the community clean.

Did you ask the person or people to "Pay It Forward"?

I didn't ask my relative to pay it forward.

If you did not ask the person to "Pay It Forward" how come?

We didn't get to ask my relatives because we were focused on cleaning up there yard and we were having fun when we were cleaning.

Part 4

Why is the idea of "Pay it Forward" important?

The idea of Pay it forward is important because one small thing that you could do to help a person could make a big difference to them. Also the person that you helped could pass it on to another person. Not just here in Canada but also around the world. Even though you worked with 1 or 2 people , It would still make a difference around the world.

Has your act of kindness made a difference?

It made a difference for them because my relatives are really busy with there jobs and taking of a teenager and my little cousin Raven. But it also made a difference for me and Gielh , We now know the importance of making a difference . 1 small thing that you could do it could make a difference to the people that your helping.

Carlo's Graphing Post

1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph

Bar Graph
Advantage- You can easily compare it two or three data.

Disadvantage- Graph categories can be reordered to sets emphasize certain effects.

Double Bar Graph

Advantage- Double Bar Graph is best for comparing two sets of data.

Disadvantage-The disadvantage of double bar graph is the interval

are hard to find and plot graph.

Circle Graph

Advantage- It's good for showing percent of total for each of the cate

gories.

Disadvantage- Is that the percents are really close and the categories.

Line Graph

Advantage- Line Graph is good for comparing

multiple continuous data sets easily.

Disadvantage- One disadvantage is that it can only use with continuous data.

Picto Graph

Advantage- Pictograph is good for comparing data that can be easily counted and represented using symbols.

Disadvantage- One disadvantage for pictograph is that its hard to tell if the picture are half or 1/3.

2. How can graphs be misleading. Show 3 ways.

1) You can make the graph wider or 3D, so the people might think that it's more popular the the

other graph.

2)Another way of misleading the graph drawing different sizes for pictograph.

3) Last way of misleading the data is distorting the graph or scale.

2a) The following chart shows Pizza Sub Sales over a month.

What 2 graphs would show the information accurately?

Answer: I would use a Bar Graph and a Line Graph.

2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.

Answer: Yes I will keep on selling pizza subs because people are more often buying pizza subs and the trend is getting higher everybody.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had

to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?

Answer: I think that I would use line graph because it show's the change data over time.

4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.

Carlo proportion Post

Carlo's Proportion Post

Task 1

• Ratio = A comparison of two quantities that have the same unit of measure.
  

• 
  
Rate = A comparis
on of two quantities that have different units of measure.
Example: you have 10 apples and you give your 5 apples to your friend. So it would look like this 10/5 or 10:5

• Proportion = An equation which states that two ratios are equal.

Task 2

1. 5 hours to travel 360 miles is about 72 mph

25 ml to 100 ml, how much should I increase the the orange juice to, to keep the quantities in the2. As a playground worker, if I increase the amount of apple juice I am serving at the playgroup from

same proportion? The orange juice is 50 ml to start with.

Task 3

What are the three ways you can prove that equivalent ratio statements are true?

3/4 = 12/16 or 4/9 = 16/32

Task 4

Task 5

1. No It isn't fair at all! Because the guy is facing 40 months in prison and he stole like a billion dollar, but the other guy has to face 15 years in prison by stealing a $100 dollars in a bank.

2.With what you know about proportion look and read what is in the image above. Does it seem just and fair? Why have you made this choice?

Answer: I made this choice by reading and looking over what's wrong in the article. I think that it is not fair if u stole a billion dollar and your only facing 40 months in jail. Then the other guy took a $100 dollar in a bank and his facing a 15 years in jail so I don't think that is really fair. AT ALL!

3. If I were the judge I would let the guy who stole $100 stay in jail in 3 days and sent him into a homeless center so they could take of him.
