Draw a diogram to show how you could represesnt the cost of an item including with or without tax.

Question #1

$ | %
100 | 100
106 | 106

The item is $100 and if the tax is $6 it would be $106 so it is
$100 x 1.06 = $106

Question #3

Kyle says that a population increases of 15% on year follows by a increase of 10% the next year is the same as a population increases of %25 over two years. Is Kyle correct? Explain your reasoning.

Kyle is not correct the population would be greater if it increased by 15% then 10% If it increased 20% it would be less.
Increased by 15 then 10

Starts at 1000.


# | %
1000 | 100 x1.15
1150 | 115

1150 | 100 x1.10
1265 |110

Increased by 25%

# | %
1000| 100 x1.25
1250| 125

How I stopped an alien invasion using proportion

It was a cold winter night when I decided to go for a walk with my friends to the skatepark, just when we got to the middle of the field we seen some sort of object in the sky, at first we thought it was a star, or an astoriod. We decided to keep walking and once we got there this object flew down towards us, and one of my friends start running, I stayed to see what was in this huge object, nothing came out of it, but a voice came from it saying, "We need three proportion math questions answered quicky or we have the right to take over your planet, if you get them all right, we will have to go back to our planet." I was looking at this object and thought maybe it was an alien ship, I then ran home to figure out the answers for these questions, while I was at it, I thought maybe I would save the world, and be famous..

1.) q.5 . What is the unit rate in each?
a. 2 pens cost 94 cents
47 cents
b.Four blocks stacked one on top of the other are 24cm high.
6cm per block

2.) q.18 . At an amusment park a new thrill ride was introduced, it costs 7.50 for 3 rides.
a.What is the wild slider's unit rate per ride?
$2.50
b.At this rate, what would it cost for 18 rides on Wild Slider?
$45.00

3.) q.26 . Two circles have a ratio of 1 to 2, Use a diagram to help answer the following questions.

a). What is te ratio of their circumferences?
1/2
b). What is the ratio of their areas?
1/4

Not quiet knowing if I got it right and if it was okay, but they were still at the skatepark, I grabbed my paper i wrote the questions and answers on and quickly ran to the aliens, I showed them what I have done, and They flew away, my friends were happy, we didn't know what would happen next.
TheEnd.

faye Pay It Forward

Part One

After watching this movie, it made me relize what such a little thing could do to make other people happy, it seems so much easier then I thought, and an act of kindness can be done in many different ways. This movie made me want to start doing more things, even after the project to help way more people, and to be a better person. I enjoyed it very much, and it wasn't hard at all, it was pretty fun, especially working with friends.

Part Two

The group I was in already did help people in Africa to get immunized against polio, I had a freat time making the bracelets with Binesi, Elaine, and MaryJane, and Elaine a lot of people helped, we would love to thank them for helping, and paying it foward, we got a spot in the library, it made it so much easiler, sinc ewe were doing it during the book fair. Parents, young students, and along with the teachers also baught the bracelets and donated money, we made over 175 dollars in 2 days and we had fun doing it, it made us feel really great. I'm also going to be giving tons of pants and stuff people would need for winter to keep warm. The group is going to be raising more money by making foam snowman and putting a little candy canes on them, and we would be giving the money to the Salvation Army.

Part Three

Well we were really nervous at the beginning, we didn't think we would make anything at all, but we made 175 dollars in 2 days, we were happy about tha. It made us feel really happy that we were going to be helping others. The people that baught them had smiles on their faces, i'm so happy they read our sign, because it was a lot of help, reason we didn't tell rarely anyone to pay it forward by donating. Im really happy with the partners I got.

Part four

This idea of act of kindness is important because the money goes to Africa to help a disease called Polio, but its especially great, because just 175 dollars helps a whole community.

I am sure it made a difference, because we definitly feel great about it, we are proud of ourselves to acomplish something this good, it's good to do this kind of thing when it also feels great doing it, it's not as hard as we might of thought. So many accomplishments by just giving a little money.
