Hello my fans and people who r just browsing the web Fridays question was If you were to have one of these super powers what would it be? 25 % voted to control who smells your farts and 75% to control time. Now I want you to tell people to watch out for my blogs tell all your friends to submit tell your friends,your brothers/siblings, and if you got one of those fancy new dogs tell them to also If you have any request for a question leave it in the comment section i promise you I will look at all of them and good ones or crazy ones will get chosen. Today many people have told me that i will get in trouble so here is today's question.Remember I make these at lunch so I do not no the result yet and if you ever want to see me make them I will be in Mr.Harbeck's math lab.
How bad do you think I got/gonna get in trouble?

Pg.180 Nr.2 4 6 8
2A rectangular prism has six faces why might you have to find the surface for only 3 of hose faces: because the other 3 are the same so u just have to times the other ones by two.
4you times all sides by each other then you add the results
6 to find the area of this triangle 9.1x4.5/2=20.475x2=40.95
3x9.1=27.3
6.4x3=19.2x2=38.4
If you add all the answers together you will get the surface are of your triangle
8 for a you just count all the faces and for b you 180x60=10800cm=108m/2x2=108
1.1mx2.4m=2.64x2=5.28
1.8x2.4=4.32
then you add all of the answers together and you get your answer

Final Percent Post
To Finish of percents we were required to do a percent video to these following questions:
1. The front wheel of a tricycle is 155% as large as its rear wheels. Use hundred grids to show how the front wheel compares to the rear wheels.
2. The cost for a downloaded game was $10.99. Added to this cost was a 10% before tax processing fee, 5%GST and 7%PST. What is the total cost of the game?
3. The number of caribou in a particular herd was monitored over a two-year period. The first year, the size of the herd was estimated at 30 000. The second year, the herd was estimated to be 90% of its original size. What was the approximate size of the herd in the second year?
4. What is a better deal:
a) 60% off a pair of shoes
b) 20% off a pair of shoes then a 40% reduction of the discounted price.
Use an example to show that your thinking.

Hendrik's Pay it forward
We had a movie called pay it forward. The movie was about a kid who did something real nice for 3 other people, those people help out 3 other people that make 3,9,.......
For my project to make a difference I walk to school every single day. This will prevent more pollution and makes up most of my part for saving the planet. If everyone would do this we wouldn't ave to worry about things like global warming.I feel cold walking too school everyday but it ends up being worth it.

For each of the following,use perfect squares to estimate the square root to one decimal place.Check your answer with a calculator
Ok so baseicly what you have to do is look at your question=18squared draw a line and see what prfect squares are closest to it=4 times 4=16,5 times 5=25,.You put the lower number on the left side and the higher number on the right side. then you you look what numbert is in between 4.5 and put that in the middle UNDER the line. place 4 UNDER the left side of the line and write 5 UNDER the right side of the line. now its time to place 18 on the upper area of the line on the left side of 4.5 but on the right of 4 dont forget this one goes over the line so it should all look like this:
16 18 25 _________________________________________________________________
4 4.5 5
so baecly what you do now is estimate Id say the square root is about 4.2.If you want the exact answer type in 18 then hit the square button on you calculator and you get=4.2426406 and thats all there is to it.

Hendrik's Sesame Street Video Post
Rate:rate is a ratio that compares two quantities of diffrent units
Ratio:a ratio is a comparason of two diffrent numbers by division
Prportion:a propotion is an equation stating that bntwo ratios are equivelant
Rate example:sequence 12,15,18,........
Ratio:4:3
Propotion:6 is to n as 4 is to 16
A more or less good copy of "You Wanna Buy An 8" sorry for the sound enjoy!

Hendrik's math profile
Hi my name is Hendrik I have been good at lots of things in math but the thing I liked the most was algebra.I like trying to find out what the number could be and there is always something new.I love the felling I get when I figured out the answer to a really hard question.
Sadly there are things I am not so good at like unit rates.most of the time it's pretty simple but sometimes the question is hard to figure out even WITH a calculater.The best way for me to improve would be to learn how to solve it on a calculator because I still don't really know how to do that.
The best blog I ever did was the one just before our first test. it was the second math blog ever made in our class.Just like Mr.Isfeld told me, I made it clear that if you don't study you will fail.
