Vicky's Finding Percent Post

HEEEYYOO.

Today in class we were practicing how to find percent out of different numbers. Our homework was to find a variety of percents out of 400.

I did this all without a calculator. I did this all in my head. So thats why I dont have any of the work to show. Because some of the answers were kind of hard to write out and explain how I've done it.

I don't know if my answers are all that accurate, but I've double checked them on my calculator to see if they were correct. If you guys find any errors you can just comment .


Sorry if it's blurry and bright on one side and dark on the other. I had to use my webcam because my camera didn't work.

Hope you guys liked my post :) COMMENT PLEEEEASE .

Vicky's Pay It Forward

What is Pay it Forward?
It is a random act of kindness that you do to 3 people. You tell them to Pay it Forward, then they will Pay it Forward to 3 other people. It can get very big. You can just say hi or just do a little good deed like picking something up for someone, and it can make there day. If you think about it, you might be able to change the world with one good deed. I also think that one person CAN changed the world. And I also think that you can make yourself a better person by thinking of others instead of always yourself.

What was your Pay it Forward act of kindness? Me, Kim, Christine, and Caitlin gave the patients of the Childrens Hospital goody bags that have little toys and candies in them. Abby, Razel, and I also donated books and toys to them.

Why did you choose this activity? We chose this because we knew that some children in the hospital would be stuck in the hospital during the holidays probably sick. Some of them probably wouldn't be able to receive a gift. So we gave the books, toys, and goody bags to cheer them up.

Who did you help? We helped the children at the hospital and maybe even the hospital itself.

What did you do? We gave goody bags, toys, and books to the children in the Children's Hospital.

When did you do your act of kindness? We did it last Monday during the lunch hour.



How did your act of kindness go? It went very well, the lady who accepted the gifts was very happy and she thanked us.

What happened? I told her that we were donating the toys, we told her that it was from us for a project. She thanked us, she was about to redirect us to Child Life Department, but then they weren't there so she accepted it for them. We also left a note for them.

How did you feel? I felt kind of nervous at first, then after I felt proud and happy that we made a bunch of children happy.

How did the people or person react? She reacted really happily and she was very thankful.

Did you ask the people or person to Pay it Forward? I did, but then she directed us to the Child Life Department but they weren't there so we didnt get a chance.

How did they react to your request? They couldn't...

If you did not ask the person to Pay it Forward how come? Because she was busy and the person we were supposed to be talking to was not there.

Why is the idea of Pay it Forward important? Because we can make people more happy and make the world a better place. Its important because if no ones gonna be a good person, who is?

Has your act of kindness make a difference? I really don't know, but i hope so.

Vicky's Scribepost, December 2nd

Today in math Ms. Usiskin told us to do the questions in the text book, or we can finish our number line inside our foldables. I chose to do the number line.

Sorry for the super bad quality, the quality got bad when I put it in blogger... idk why. & sorry if the pictures are so small,if i made them any larger it would've been too blurry to see. I probably didn't complete this part of my foldable either. Sorry :)

Well, I didn't know what else to label, so thats all I could think of. Sorry if its so plain.

COMMENT PLEEASE ! :)

How I stopped an Alien Invasion using Proportion

A UFO was flying above my house. I went outside to check it out. The UFO landed right in my yard. A little martian stepped out, I asked him what he was doing here. He didn't say anything, he threatened me that he'd take over the world with aliens and later on unicorns if I won't give him at least 3 proportion problems. He also demanded me to teach him what proportion was. So I taught him that: proportion is a relationship that two ratios or two rates are equal. It can be solved in two ways; chart form and fraction form. Here were the problems I answered for him.

4. Determine the unit rate.

a) Three dinner rolls cost 99 cents.

- 1roll/33cents

b) Seven identical objects have a mass of 14kg.

-1object/2kg

14. Last night 30 cm of snow fell in 6h. If it continues snowing at the same rate, how long will it take for 45 cm of snow to fall?

- It will take 9 hours to have 45 cm of snow.

23. According the Guinness Book of World Records, the smallest horse is is Thumbelina. Thumbelina is 42.5 cm small and eats about 0.3 kg of food per day. A former world record holder ate food in the same proportion to its height. If it was 46.25 cm tall how much would it eat? Give your answer to the nearest hundredth of a kilogram.

- It would eat 0.33kg.

28. The dosage of a certain medicine for a child is 2.5ml for each 3kg of the child. What is the dose, in mL for a child with a mass of 16.5kg.

- 13.75 ml for a child with a mass of 16.5 kg.

The Aliens then left in there pink UFO.

Don't forget to study you guys! Good luuck!

%%%%%'s Rate Growing Post

Rate - Compares quantities in units.


Ratio - Compares 2 quantities measured in different units.





The difference bewtween ratio and rate is ratio compares two quantities that are the same, rate compares two quantities that are different.








6. Gina earns $78 for working 6 h. Asad makes $192.50 after working 14 h. Determine each persons unit rate of pay. Who has a greater hourly rate of pay?


Gina - $13/h


Asad - 13.71/h


Asad has a greater hourly rate of pay.





10. Trevor rode his mountain bike 84 km in 3 h. Jillian rode 70km in 5 h. Who is the faster cyclist? How do you know?


They both rode at the same speed.


Jillian rode her bike at 28km/h


Trevor also rode his bike at 28km/h





QUESTION: If Jill runs up 10 metres of the hill in 5 minutes, how much does she run in 1 minute?


Jill runs 2 metres up the hill in a minute. 2m/min





PART 2


1) You would have to multiply all the ingredients by 2.5. Because the portion is 4 and to get the portions to 10 is to multiply it by 2.5.


2) I would divide the recipe for 10 buy 10 to get the portion for 1.


DONT FORGET TO STUDY TOMORROW FOR THE TEST! :) GOOD LUCK EVERYONE

Vicky's Post Question 16

Heather used a copier to make the following 50% reduction.
(I CANNOT PROVIDE A PICTURE, MYTEXTBOOK DOES NOT WORK)
a) Write the ratio of the length A'B' compared to the length of AB.
The ratio of the length of A'B' compared to the length of AB is 1:2
b)Write the ratio of the length of A'C' compared to the length of AC
The ratio is also 1:2
c)Use your knowledge of ratio and percent to explain the meaning of a 50% reduction.
50% reduction (ratio) is like 2:4 that is reduced by a half / 1:2. In percent it is like 100% turned into 50%

Sorry this post is so late. (:

Vicky's BOB Ratio Post

PART TO PART RATIO:

brown to orange - 3:2

green to grey - 3:1

blue to yellow - 4:2

PART TO TOTAL RATIO:

white to total - 1:22

pink to total - 2:22

THREE PART RATIOS:

blue to green to peach - 4:3:1

pink to brown to white - 2:3:1

RATIO NOTATION, FRACTION, DECIMAL, AND PERCENT:

peach to blue - 1:4, 1/4, 0.25, 25%

EQUIVALENT RATIOS:

orange to green - 2:3, 4:6, 6:9 etc... Those are all equivalent fractions. You can make equivalent fractions by multiplying or dividing the ratio. But you always have to remember to always do what you did to one side you always have to do to the other.

QUESTIONS:

1. Show 3:1 as a fraction, decimal, and percent?

2. Give an equivalent ratio to 4:3?

3. How do you make a fraction for a three part ratio?

Thank you for viewing my post everyone! Don't forget to comment. Remember to study. Good look on your tests! :)

BOB 2

The mistakes I made on my test were:

Multiple Choice-

4. Four students are running for student council president. Of 30 students polled, 15 chose Mike, 3 chose Patricia, 6 chose Brian, and the rest chose Karen. What is the ratio of votes for girls to votes for boys in the student council election? Express the ratio in lowest terms.

- My answer was d/21:9. The actual answer was a/3:7. My mistake was I misread the question/word ratio. In the future I will read through the question twice.

7. A rapid transit train has 39 passengers on it as it starts its run. At the first stop 12 passengers get off and 18 passengers get on. What is the ratio of the number of passenger who were on the train as it arrived in the first station to the number who were on the train when it left the first station? Express your answer in lowest terms.

- My answer was d/27:39. The acutal answer was b/13:15. My mistake was I didn't read the question well enough. In the future I will read the question more well.

8. A picture frame has a width to length ratio of 5:7. If the width of the photo is 9 cm, the length of the photo of the photo is.

- My answer was a/11cm. The actual answer is b/12.6 cm. My mistake was I thought that you could use addition in ratios. In the future I will not use addition in ratio questions.

Completion

14. What percent (to one decimal) of the group prefers toasted O's?

- My answer was 15.1%. (Sorry, I dont know the actual answer to this question.) Next time I will use a ratio chart to solve the question.

Short answer

15

D. Write each ratio in lowest terms. (18:27)

- My answer was 9:13.5. The actual answer was 2:3. In the future I will try to find more ways to get the correct answer.

16. You have a bag with one white ball, six red balls, eight green balls, and three purple balls. In lowest terms what is the ratio of red balls to the whole bag of balls?

- My answer was 1:2. The actual answer was 1:3. My mistake was I thought that the question meant the red balls compared to the rest of the balls. But now I know that it means all of the balls together compared to that group.

17. Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.

- My answer was Baseball Team A and Hockey Team A. The actual answer was Baseball Team A to Basketball Team A. My mistake was I thought the answer was about addition. But it was actually about division. In the future I will not use addition.

Vicky's Coin Scribepost

On October 9 we worked in groups to make up questions about a jar that is full of American coins that values $100. We have to make a scribe of 2 questions. One PURPLE question and one RED or BLUE.





QUESTION 1: Would the jar look the same if it were converted to Canadian money?
My answer is no. It would not look the same. It would not look the same because Americans use paper money unlike Canadians which we use coins "Loonies and Toonies". The jar would probably look less full because the loonies
and toonies would replace all the other
coins



QUESTION 2: How full is the jar?
By the looks of it, the jar looks 3/4 full. Because if you divide it in a half then divide those halves in half it would turn into quarters. The coins only take up 3 quarters of the jar. (Sorry if it wasn't very mathematical)





Sorry that this picture is kind of inaccurate.
It includes the 50 cent coin which doesn't
really count. :)


Thanks for viewing my blog! Don't forget to comment!



Happy Thanksgiving everyone! Hope you all had a good one! ^_^


Part 2:

OCT 13

QUESTION 1: How much of the jar is filled with Canadian coins?
I know that there are 370 coins worth of coins in the jar. The amount of American coins is 780. The amount of Canadian coins are 370 coins. 370 is about half of the 780 coins. So I just divided the 75 into 2 which is 37.5 and that gives me my answer. The Canadian coins occupy about 37.5% of the jar.



QUESTION 2: Could you fill the jar with $100 American and $100 Canadian?
No you can not. To get this answer I first used the information I knew. Which was the amount of American coins were 780 and the percentage that the American coins filled the jar was 75 percent. Then I had to figure out the percentage of the Canadian money. The amount of coins of Canadian coins were 370. So I used a ratio chart and found the percentage of it. The percentage of the Canadian coins were 48%. So I added botht the percentages together. It equalled 123%. Then 23% would be left over on top of the jar. So the jar can not hold the American and Canadian coins.

Three things I know about graphing.

1) You can distort a bar graph by putting a break in the y axis to mess up the graph, or you can make a bar fatter.

2) The intervals on your bar graph have to be the same.

3) You always have to put the labels and the title.

What I could've done to improve my mark on the assessment...:
I could've put the labels and x and y axis but I forgot. I also forgot to put the sums. I could've gotten a higher mark by using a tally chart.
I got 8/25 on my assessment...

FAIL! :(

Vicky's Graphing Assessment

Numbers in ascending order: 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 8, 8, 8, 9, 9, 10, 10, 10, 11




GRAPH A (Accurate)

Graph A is the normal bar graph. This graph shows that the sums 5, 6, and 9 all were rolled the same amount of times. And 11 was only rolled once.

GRAPH B (Distorted)

Conclusion Graph B:

To distort the accurate graph I made the grey bar (the bar representing the sum 11) fatter. I did this so it looks like 1 is kinda bigger and noticable. (Sorry that I couldn't do anything else like make a break or make the intervals different).

Vicky's Scribe Post for Sept 30

QUESTION 7

a) Which burger seems to be the favourite? Explain.

The Big Cheese burger seems to be the favourite. Because it is bigger than the Bonzo Burger.

b) How is the graph misleading?

It is misleading because it doesn't say how much people were tested and you don't know if The Big Cheese burger is actually precisely 12% larger

than the Bonzo Burger.

c) How should the graph be redrawn to represent

the data more accurately?

This can be redrawn into a bar graph to make it

more accurate.
