b) It is a linear relation because all the points are in a straight line when they are connected and the pattern keeps on repeating.

c) It could be possible because Klaus could work part of an hour and gets a pay in his partly hour. 






a) Table of Values

a) The graph is about how much income the Grade 8's are  earning form having a car wash.

b)The pattern goes over 1 then up 10 in the chart so basically you have to  multiply C with I.

c)In the chart it says that 1 car is $10 so 1 car wash is $10.

d)


e) So what you do here is you have to multiply 15 with 10 so the answer $150.







Chapter 9 Practice Test Page 362 Questions 2 & 3

My answer for this question is B because in the table of values the toothpicks in base is 1 and the toothpicks in perimeter is 3, so they got that because what they did is 3b and they did that to the rest.

My answer that I choose is C because the answer follows the same thing like the graph in this question.

Kristina's Pay It Forward

Part 1:

What is Pay It Forward?

Pay it forward is an act of kindness that when you help them you don't ask anything in return. Pay it forward starts by one person helping three people, then after those three individuals will help three people. This cycle could go on until we could make a big difference in the world.

Part 2:

What was your act of kindness?

My act of kindness was to help clean the church. I cleaned the glass door of the Church and swept the floor.

Why did you choose this activity?

I choose this activity because there is a church that is close to our home and I was thinking about it first. Then after I asked my dad if I could clean the church( My dad is the care taker of the Church) for my pay it forward.

Who did you help?

I helped my dad because he was the only one cleaning the church and the other staff there.

What did you do?

I helped clean the church.

When did you do your act of kindness?

I did my act of kindness on November 28,2012.

   

Part 3:

How did your act of kindness go?

My act of kindness went pretty well.

What happened?

When I got there I asked where is the cleaning supplies to clean the door. When I got it I started to clean it until people started to come for mass. After my dad gave me the broom so I could start to sweep the Church hall. Then when I finished sweeping I went up stairs to attend the mass.

How did you feel?

I felt tired after cleaning, but it felt nice that I could clean the community.

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

I did't get to ask the person to pay it forward.

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

I didn't get to because I was too busy cleaning that I forgot.

Part 4:

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

The idea of it is important because sometimes people forget. If you keep paying it forward more and more people will do it, next thing you know pay it forward could spread. The more and more people do it more people will know about it and do it.

Has you act of kindness made a difference?

They don't have to clean the floor and the glass that day.

It Starts With You.......Pay It Forward.

How many groups of 1/4 are in 6?
There are 8 group of 1/4 in 6.

The first thing you do is make the 2 into two over one (2/1). After divide it to 1/4. Make the 1/4 into a reciptical(4/1). Multiply 2/1 to 4/1 so the answer is 8.  


13)

How many groups of 3/4 are in 6?
There are 8 groups of 3/4 in 6. 

The first thing you do is make the 2 into six over one (6/1). After divide it to 1/4. Make the 1/4 into a reciptical(4/3). Multiply 6/1 to 4/3 so the answer is 24/3 then put it into lowest common denominator so the answer is 8.

Everything Kristina knows about Fractions

Kristina's Proportion Post

Part 1: Definitions

Ratio: A ratio is a comparison between two numbers (eg. 1:2 or 1 to 2)
Rate: A rate compares two quantities but in a different unit (eg. 20km/ 2hrs)
Proportion: A proportion is two equivalent fraction, rate or ratio (eg 1/2=2/4)

Part 2: Questions

1) 5 hours to travel 360 kilometres is about _____km/h.

2) Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save last week?

Part 3: Equivalent ways

Part 4: Video

Part 5: Social Justice

1)it is not fair.
2)I don't think it fair for him to stay in jail for 15 years.
3)I made this choice because he admitted that he stole the money and said he was homeless and hungry. Another one is instead of him stealing more money the CEO had 3 billion and he got sentenced for 15 years just by stealing a 100 dollar bill.
4)If I was a judge I will still make him go to jail but not for 15 years but only 2 years because he did need the the money but he shouldn't have stole it.
