Melbourne Cup Questions

q1

In the past decade the average Melbourne Cup weight carried to victory is 5480g.
The heaviest weight carried to victory was Carbine, sire of Phar Lap, with 6630g in 1890.
Phar Lap actually carried the highest weight with 6800g but lost.
The lowest weight carried to victory was Banker with just 3350g in 1863.

q2

1. For the first placed horse in 2011, how much did the owner, trainer and jockey each receive?
$6,175,000 is the prize pool amount. 85% of the money goes to the owner which is $5,248,750. The trainer get’s 10% which is $617,500 and the jockey gets 5% which is $308,750.

2. For the tenth placed of $115,000 how much did the owner, trainer and jockey each receive?
The owner got $97,750, the trainer got $11,500 and the jockey got $5,750.

3. How much of the total prizemoney has increased each year, as a percentage of the previous year
(state the amount and the percentage increase).
The total amount increased from $5,000,000 to 6,200,000 is $875,000. The percentage is a 24% increase.

Red Bull- Red Bull Gives You Wings 2000
https://www.youtube.com/watch?v=K31dg86OmuM
Description: This advertisement shows a man just walking, until a bird flies over him and poops on the man’s shirt. The man then gets out a handkerchief and wipes off the poop. After that, the man takes out the red bull from his bag, drinks it, wings appear on him, he flies over the bird and urinates on the bird.
Information: This advertisement can be found on youtube and possibly on TV at the time it was being aired. I think this ad is for anybody really, because of the humor and how different it is. The purpose is most likely to use humor to get more people to buy Red Bull drinks. In the video, it presented a man getting revenge to become satisfied. People that buy this product may also want to become satisfied and have ‘wings’. The company that produced Red Bull have made many Red Bull ads with humor which grabs people’s attention and want to buy the product.

Colgate Total Toothpaste
https://www.youtube.com/watch?v=99T-iGcii8U
Description: The beginning shows a man asking a lady if she brushed her teeth this morning, then he scans it and they both see bacteria on the screen. After that, the man introduces Colgate Total Toothpaste to the lady and then the advertisement tells you the benefits of Colgate Total Toothpaste and what bacteria can cause. At the end of the ad, it says that Colgate is the number 1 toothpaste brand that is also used by dentists.
Information: This advertisement is also a video advertisement. It is targeted at adults because adults want healthy, shiny teeth more than younger children that may not care about their health or are too young to understand the importance of being healthy. The last sentence makes you want to use this product because your dentist knows what’s the best product for teeth to stay healthy.

Harvey Norman Ad
https://www.youtube.com/watch?v=GmeqI8pcsMI
Description: This ad first talks about deals on the products, then it ends with a jingle that goes like “Go Harvey Norman! Go!”
Information: The jingle makes everyone remember the store. I’ve heard it multiple times on the radio in the car. So whenever someone wants to buy a TV, they will remember that Harvey Norman will welcome them with open arms. This advertisement is targeted at adults or young adults that will nag their parents into buying a TV. It may also be targeted at families who take a sport seriously enough to always watch the live games on TV.

FurReal Friends UK- My Lovin’ Pup
https://www.youtube.com/watch?v=iBy0B4OPHI4
Description:This ad is for a toy electronic puppy called Biscuit. The video shows the cool features of this toy and says at the end “Biscuit, my lovin’ pup, be sure to become your child’s best friend”.
Information: I think this is definitely targeted at young boys and girls and also parents that don’t want to buy a real puppy. This advertisement is on youtube and is very unique in my opinion. The video also makes me want to buy one since it can do what real dogs can do and I find it amazing that a robotic pup could be so similar to a real puppy. The video also shows a happy girl hugging the pup which might make parents buy it so they can see their child being happy like that girl.

Emporium Melbourne Train Ad
Emporium 1

Emporium 2
Description: This ad is printed on a few trams in Melbourne. It shows a guy wearing stylish clothes and has ‘Emporium’ written in a bold design.
Information: The Emporium is a very popular centre in the city. Some people only go there because they’ve heard great things from it. The fact that the Emporium has many of the most famous stores in the world would already draw in shoppers. The advertisement however, seems like it is targeted at young males that want to look stylish. It is like the domino effect. When someone sees a great store, they tell all their friends and those friends tell other friends and it continues on.

Maths Extension Group- Reflection of Mindstorm Robot Project

On the first week of our mindstorm projects, the entire class got split into groups and started to build the body of the Mindstorm robots. My group was a bit behind in the constructing and we also had a team member that was absent, but we somehow managed to get most of it done. There was a problem where there was a piece on the instruction manual that we just couldn’t identify with the other pieces and wasted some time, but in near the end, we finally found the piece. We also had to take the core of the robot and charge the battery inside it to make sure it was working for next week.

The second week was a mix of constructing and programming. My team finished constructing the body, put on the charged core, and also added a sound sensor which would enable the transitions between each programmed action. After a few minutes to add some finishing touches, the teacher told us that we had to make our Minddstorm robots try to follow the taped line on the floor as accurately as possible. My group’s robot only went 40% of the way, yet we still got the highest percentage.

On the third week of our Mindstorm project, the objective was to showcase a trick/make a different robot (using the internet). My group decided to add a part that could be added without removing any parts. It was a hand that could push a ball. We only had a few pieces to finish the hand, but the time was up. Luckily, before we decided to add a hand, we had already made a pressure sensor that would make the robot move back, then forward, then back, then forward and continuing like that. So that’s what we showed the class.

The Mindstorm project was very enjoyable and a fantastic experience. I thought that the programming would be really hard and tricky, but it was actually okay since it was the basic type of programming. When we watched a few youtube videos of other different Mindstorm robots created by others, it was truly amazing to see so many ideas that could make a great Mindstorm robot.

Budget Basics

Kayla’s Budget of the Week

Budget Worksheet

Kayla earns $40 a week. She also saves up $7 a week. A trip to the movies cost $14, so after 2 weeks, she can go to the movies.
Kayla doesn’t have enough money for all the items, but after many weeks of walking the dog and her weekly allowance, she can definitely spend her money on the items.
She uses at least $10 each week for lunch, so that means, to save up money, she should be buying most of the items she needs and then carefully choose a few wanted items to buy.

Stop Animal Cruelty

The world is filled with injustices, such as animal cruelty. As the picture below proves, over 200 pets are killed or maimed each day.

Fact of animals

 

 

You could be the voice for all these animals, let everyone know they’re suffering.

 

Animal-puppy

There are no such thing as monsters, but there are abusive people whose hearts are just like monsters.

You can change the fate of many animals, if you just try a little bit harder.

You may not remember the animals that you might’ve helped save, but they will never forget your kindness…

Kinetic and Potential Energy

Kinetic Energy

Kinetic energy is energy that is created by forces of movement that can include rubbing, accellerated speeds and pushing/pulling.

Examples:

Doorbells

A flowing river

Clapping

Potential Energy

Potential energy is energy from an object that has the potential to give off its own energy. Potential energy is more focused on the condition rather than the motion.

Examples:

An archer’s bow with the string pulled back

A teapot before the water is boiled

A child at the top of a slide

Triolet Poem

He can become everything, yet also nothing, all at the same time.
It’s like you can tell him all you know and not get bored.
Whenever he is near, it’s like facing a great climb.
Spending time with him is so rewarding, it would cost even more than a dime.
Not treasuring the memories you make with him would be considered a crime.
His imagination sure is magical, he can make you believe an apple was a sword.
You can believe the words that exit his mouth, it all changes his personality into a sweet lime.
My younger brother truly deserves an extravagant reward.

Number Pattern

First you square a number
e.g. 6×6=36
Then add one to the first number and subtract one from the second, then multiply.
e.g. 7×5=35

As you can see, the total of the second equation is one less than the total of the first equation.
This pattern is the same with other numbers.
Examples:

1.
52×52= 2,704
53×51= 2,704

2.
62×62= 3,844
63×61= 3,843

3.
72×72= 5,184
73×71= 5,183

4.
82×82= 6,724
83×81= 6,723

5.
92×92= 8,464
93×91= 8,463

With those examples above, you will notice that the last digit of each of those equations end with a 4 for the original equation and a 3 for the modified equations. I have also discovered that the tens column is counting by 4s. It starts with a 0, then 4, then 8, then 2 (2 from 12) and then a 6 (from 16).

This pattern also works with 3-digit numbers.
Examples:

1.
100×100= 10,00
99×101= 9,999

2.
200×200= 40,000
199×201= 39,000

3.
300×300= 90,000
299×301= 89,999

I think the reason why this pattern is like this is because of the equality of equations. You add 1, then subtract 1. If you add 100 onto 100, that would become 200. If you add 99 onto 101, it’s still 200.

Adding and Subtracting 2

1.
100×100= 10,000
98×102= 9,996

2.
200×200= 40,000
198×202= 39,996

3.
300×300= 90,000
298×302= 89,996

Doing this pattern with 2 ends up having a difference of 4 numbers. This may be because the numbers that are getting multiplied have a difference of 4.

Adding and Subtracting 3

1.
100×100= 10,000
97×103= 9,991

2.
200×200= 40,000
197×203= 39,991

3.
300×300= 90,000
297×303= 89,991

Now there is a difference of 9 between the first totals and the second totals. I think that’s because 3  squared is 9 and you subtract that from the first total to make the second total. It also works with 2, because 2 had a 4 difference and 2 squared is 4. 1 squared is just 1 so that is what was subtracted from the squared total.
