16.A fitness room center will install a square hot tub in a 6m x 6m room. They want the tub to fill no more than 75% of the rooms area.
A)what is the maximum area of the hot tub?
B) what dimensions to a tenth of a meter will the fitness center order from the manufacturer? Explain.
9) what are all the possible whole numbers that have a square root between 4 and 5?
A: 17, 18, 19, 20, 21, 22, 23, 24
Here is a video for square and square roots:
Pythagoras:
1) Explain the Pythagoras Relationship: The relationship between the lengths of the sides of a right triangle. The sum of the area of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotenuse.
2) What is the missing length?
It is 13cm because the hypotenuse ( or C ) has to be a larger
number than the legs ( or A, B ).
3) Is this a right triangle ? This is not a right triangle because a square + b square does not = c square also the legs added together does not equal the hypotenuse.
These are the questions that i will do from the textbook: 1, 4, and 5.

My we day experience was the most fun i ever had. I learned so many things about how you can change the world and that " you have the POWER". Going to we day is such a big opportunity because only a few students from Sargent Park school could go and I was one of those people that wanted to change the world.
There were so many people that inspired me like " Hannah Taylor, Spencer West, Mia Farrow, Rick Hansen, Craig Kielburger, Marc Kielburger, and so many more. I couldn't believe that me just that one person could do something about changing the world but with the help of them all saying " What we've got to do is put the power and responsibility in the hands of the communities" or "If enough of us choose to change even one small thing, together we have the power to change anything" and one I mostly remember is "you are never to young to change the world".
Together WE can make a difference just like all of those inspiring people.
IT STARTS WITH ....ME AND ENDS IN .... WE
Also during the We Day celebration Craig and Marc always made us say WE ARE by saying the we committing to changing the world. Also they talked about the vow of silence. That is for children who have no right to speak out and they have to work and be in child labor. On November 30,2011 I will the participating in the vow of silence and i hope YOU WILL TOO.
Join making a difference and being a part of we day! Let those people inspire you to make a difference in the world and trust me after hearing the speeches I want to go to Kenya or build a anything to put a smile on someones face.
1.) Pay it forward is when you do an act of kindness with nothing in return.
In the movie Traver's teacher gave the class an assignment to pay it forward. A boy named Traver bought home a homeless man and took care of him. After Traver thought of a plan where if he helped one person that person would help another person and then it would keep getting bigger and bigger and more people would get involved in pay it forward.
What was your Pay It Forward act of kindness?
My act of kindness that I chose was baking cupcakes for all the teachers and EA's at Sargent Park School.
2.) Why did you choose this activity?
We chose this activity because we felt that baking cupcakes will put a smile on teacher's faces and in a way that is making a difference.
Who did you help?
We helped all the people working at Sargent Park School.
What did you do?
First what we did was my group and I went to Michael`s and bought some thing to help us with the icing on the cupcakes. We also ended up going to Sobeys and buying the ingedients for the cupcakes. The next day me, ronalen, and Kassey all went to Kassey's house and baked honey cupcakes and iced them with vanilla frosting. Then on Monday at lunch we gave them out to all the teachers and EA`s at Sargent park school. Lastly, at the end we all got great feedback when we gave the cupcakes out. (:
When did you do you act of kindness?
We bought the ingredients on Saturday and made the cupcakes on Sunday and delivered them on Monday
3.) How did your act of kindness go?
My act of kindness went very well considering that we made all 105 cupcakes and they were all gone at the end it went very well.
What Happened?
what happened was after we made the cupcakes on Sunday we delivered them on Monday to all the people who work at Sargent park.
How did you feel?
After doing my act of kindness i felt GREAT because when i told people "would you like a cupcake" some worker were like " how much are they" and i said nothing at all they are free. Then i could see the smiles on the workers faces after we gave them a cupcakes.
How did the person or people react?
All the teachers or helpers were surprised and happy every time my group and i would give a cupcake they would POP up with a smile (:
Did you ask the person or people to "Pay It Forward"?
Yes, my group and I did ask people to pay it forward.
How did they react to your request?
some people would even ask what is it so we would explain what it is and we would also explain part of the movie pay it forward so people would know what it is. Other said oh okay thank you very much i will do that.
Why is the idea of "Pay it Forward" important?
The idea of pay it forward is important because we need to be inspired to change the world and having the chance to do something kind with nothing in return makes you feel really good about yourself " It starts with ME and ends in WE" and what that means is if one person can do it then it will inspire three people and then those three people will turn out to be nine people changing the world and i think no matter how old or how young everyone can make a difference.
Has your act of kindness made a difference?
Yes, i think my act of kindness has made a difference because with the smallest change like putting a smile on someones face or even just making someone day with a cupcake you have made a difference.
Here Me, Janessa, and Ronalen have made these video of making our act of kindness.
Data can be presented usingbar graphs, double bar graph, circle graph, line graphs, and pictographs.
Different graphs may provide different information and display certain types of data better.
Bar graphs: advantages: -are best for comparing data across categories. disadvantages: - graph categories can be recorded to emphasize certain effects.
-Use only with discrete data.
double bar graph: advantages: are best for comparing two sets of data across categories. disadvantages: The intervals on the double bar graph can be inaccurate.
circle graph: advantages: are best for comparing categories to the whole using percent. disadvantages: it takes a lot of time and there is a special way of doing the circle graph.
line graph: advantages: are best for showing changes in data over time. disadvantages: it only will show data over a long period of time.
Pictographs: advantages: are best for comparing data that can be easily counted and represented using symbols. disadvantages: icons must be the same size and it is hard to see how much the picture is showing.
2) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately? a) I would use a line graph or i could use a bar graph to show this information accurately.
b) yes, i would continue because the sales are going up a lot and that shows that the pizza subs are very popular and they should still sell them.
3) a) If i were to choice a graph i would choice the line graph because it shows that the sales are increasing. b)
Task 1. Ratios Two- term ratio: compares two quantities measured in the same unit.
Three-term: compares three quantities measured in the same unit. Part-to-Part ratio: compares different parts of a group to each other.
Part-to-whole: compares one part of a group to the whole group.
Rates: A comparion of two quantities measured in different unit. Ex. $1.69 per 100 grams or $1.69/ 100g
unit rate: A rate in which the second term is 1. Ex. 64 beats/min is unit rate.
PROPORTION:
An equation which states that two ratio or fraction are equal.
Task 2.
1 1. 5 hours to travel 360 miles is about 72m mph
2. As a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, how much should I increase the the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with. Answer: 200ml
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
Answers: 1. first, you can do it horizontally. What you do is you divide or multiply the top left to the top right and do the same thing at the bottom.
2. Next, you can do it vertically . What you do is you can divide or multiply the top left then the bottom left and do the same thing to the opposite side.
3.Finally, you can do it diagonally. What you do is you could dive or multiply the top left and the bottom right and then do the same thing to the top right and the bottom left.
Task 4.
Hope you enjoy the proportion video.
Task 5.
1.Does it seem fair? NO, it doesn't seem fair at all.
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? No it's not fair because this man who stole $ 3 billion dollars only is in jail for 40 months. Then this other guy gets 15 years in prison for stealing $100 dollars and bringing it to the police and saying"I did it."
3.What would you have done if you were the judge? I have made this choice because the man who stole $ 100 should have only been in jail for like 1 week, and the other guy should of gotten 20 years in prison.
