What we learned in class today was how Angles could be viewed by different ways on how people may look at it. I learned that ANGLES OF DEPRESSION is a type of shape if you were to view it looking downwards, it doesn't matter where you look there always seems to be a shape. Also another type of angle i learned in class was ANGLES OF ELEVATION, how you may see an angle just be looking up or at the sky, there would always seems to be a shape no matter how you see it.

Similar Triangles
Hello people , I will share what I have learned in today's class topic which is about similar
triangles. For you to know if triangles are similar the ratios should be the same and the angles
should be " congruent ". One more thing that i have learned is the square boxes inside a triangle
indicates that the angle is at a 90 degree angle and all triangles has a 180 degree angle to figure
this out is you add all the angles up. Another thing that I have learned that just came into my
mind is "Correspond" which has something to do with triangles too and we call it "Corresponding
Sides".
I couldn't explain it anyhow by words so I'd use an example cause i feel its much easier to understand.
A B C and
E F G
Side AB corresponds to Side EF
Side BC corresponds to Side FG
Side AC corresponds to Side EG
with both triangles having congruent angles and corresponding sides both triangles will be similar.
I have shared with you what I have learned today hope this will you people :] .

We started off by Mental math then marked our papers. Then we were taught how to calculate the surface area of 2 boxes.
A box with 4cm Length, 4cm Width , and 4cm Height:
6x4x4=
6x16=96cm2
A box with 15 cm Length, 2cm Width, and 4cm Height:
=2(15x2)+2(15x2)2+(2x2)
=2(30)+2(30)+2(4)
=60+60+8
=128cm2
After we did a quiz to review the things we've been doing in class to get ready for our exams. I had a pretty difficult time with it. But I'm getting more familiar with the shape formulas and things like that. Hopefully i get used to it before exams start.
The next scribe will be Aaron.

We started off with some mental math as usual. Then after marking each others paper we were taught how to represent scales in two different ways.
Example:
1:25 can be shown as..
-1 unit to 25 units
-1 over 25
-1/25
-1 cm represents 25 centimeters
-1 inch represents 25 inches
Example:
-1 cm represents 6 km
-1cm to 600 000cm
-scale : actual
-scale over actual
We also reviewed K-H-D-M-D-C-M. Then after we did some other scale activities.

Well first off, today, we started by coming into the class and chatting to the people that sit near us. We stood for O'Canada and sat back down. Class started with Mental Math, as usual. Remember, if you got something wrong, you should come back to the Blog and see where/how you got the question wrong. Everyone should be getting 9 or 10's!
After the Mental Math, Mr. Kuropatwa asked us if we liked working in groups or solo. With the awesome response he got, we were divided into groups and worked on many questions. We basically worked on Perimeter/Circumfrence and Area questions.
Right at the end of class, we quickly looked at the formulas for Surface Area and Volume.
FORMULAS
PERIMETER/CIRCUMFRENCE
Triangle: P = a+b+c
Rectangle: P = 2 (L+W)
Square: P = 4s
Circle: C = πd OR C = 2πr
AREA
Triangle: A = 0.5bh
Rectangle: A = LW
Square: A = s2
Circle: A = πr2
Trapezoid: A = 0.5(Base 1 + Base 2)h
SURFACE AREA
Rectangular Solid: SA = 2WH+2LW+2LH
Sphere: SA = 4πr2
Cone: SA = πrs (Slanted Sides Only)
Cylinder: SA = 2πrh+2πr2
Pyramid: SA = Area of Base + Perimeter of Base x Slant Height
VOLUME
Rectangular Solid: V = LWH
Sphere: V = (4/3)πr3
Cylinder: V = πr2h
Pyramid: V = (1/3)b2h
Anyways, CHRISTMAS IS 7 DAYS AWAY! =D and The Next Scribe Will Be: Cait ;)
Merry Christmas and Happy New Year! =D

Today we talked about the Golden Ratio. We talked about how are body and alot of other things will work this way.For example If you measure your arm, and then your elbow and down and you divide the long ways by the short way you will get the number 1.618 (That is the Golden Ratio) and if it`s not 1.618 it will be very close.
After we talked about that we went to a question about sales and rate savings.Here's an example.
Corey buys a jacket on sale for $53.99. Before the sale the jacket cost $63.89. What is her percent rate of savings?
1. First you have to divide the sale price by the original price.
sale price/original price = $53.99/$63.89 = 0.8450
2. Then you round it off.
0.8450 rounded off to 0.85 = 85%
3. Then minus the percent from 100% and you find the rate of savings
85% - 100% = 15%
Corey got a 15% rate of savings.
Here is another example of something we did....
new/old
1 Shirt $16.99/$18.99 = 89% 89% - 100% = 11% off
2 Pairs of socks $2.67/$3.29 = 81% 81% - 100% = 19% off
1 Sweater $19.99/$25.50 = 78% 78% - 100% = 22% off
After That we has to find out how much the tax would be for all of these items in total.
$16.99 + $2.67 + $2.67 + $19.99 = $42.32 - total items
GST - 0.06 x $42.32 = $2.54
PST - 0.07 x $42.32 = $2.96
$42.32 + $2.54 +$2.96 = $47.82 - total incl. taxes**
We also talked about ratio's and how they could compare a part:part or a part:whole
The Next Scribe Will Be Serena After Mary.
** And There`s Going To Be a Test,Friday December 7th**
Good Luck To Everybody!!.

math
Sorry guys, my internets down.
Thursday in class we skipped mental math and went straight to a test about compairing unit prices. for example:
if Neil finds canned peas offered for sale at three cans for $3.19 in one store, five cans for $4.10 in a second and eight cans for $4.98 in a third. Which store has the lowest unit price?
Step 1:You have to divide it by itself to get one.
Step 2:You have to divide the same thing to the price.
Step 3:You have to comair the unit price of each store and see who has the lowest price.
First you have to find out how much the unit price is for one can for each store.
For the first store there`s three cans for $3.19 . You have to Divide 3 by 3 and the divide the price by 3 and you find the price of one:
3/3 = 1
$3.19/3 = $1.0633 (unit price)
For the second store there`s five cans for $4.10. You have to divide 5 by 5 and then divide the price by 5 and you find the price of one:
5/5=1
$4.10/5 = $0.82(unit price)
For the third store there`s eight cans for $4.98. you have to divide 8 by 8 and then divide the price by 8 and you find the price of one:
8/8 = 1
$4.98/8 = $0.622(unit price)
store 1 - $1.06
store 2 - $0.82
store 3 - $0.62
The lowest unit price/Best buy is eight cans for $0.62
------------------------------------------------------------------------------------------------
After that we started to do some work on taxes. (GST & PST)
For Example:
How much tax will susan pay when she buys a stereo surround sound priced at $2595 in Manitoba?
How much will she pay all together for the system?
Step 1: First you have to find out how much GST(6%) will be.
Step 2: Second you have to find out how much PST(7%) will be.
Step 3: Third you have to add the two taxes together to find the total tax.
Step 4: Then you have to add the Price($2595) to the taxes.
[1] 6%/100 = 0.06 0.06 x $2595 = $155.70 (GST)
[2] 7%/100 = 0.07 0.07 x $2595 = $181.65 (PST)
[3] $155.70[GST] + $181.65[PST] = $337.35 - Total tax
Susan will have to pay $337.35 in taxes.
[4] $155.70[GST] + 181.65[PST] + $2595 = $2932.35
Susan will have to pay $2932.35 all together for the system.

In today's class we started with mental math on spreadsheets. When we finished correcting the papers, Mr.Kuropatwa began talking about Sales Tax.
- Sales Tax consists of GST and PST:
GST: Goods & Services Tax (if buying basic needs such as food, clothes)
PST: Provincial Sales Tax
Mr.Kuropatwa had told us about taxes and how they change every year. He also mentioned a thing or two about what kind of things were never taxed. Such as books, because they contain information to educate, and food because its basic requirement.
Goods & Services Tax
Some examples of GST would be:
- If you buy 6 dozen muffins, you won't be taxed.
- If you buy less than 6 items, you were buying a "service".
- Buying 6 muffins you wouldn't get taxed. (prepared foods)
- A haircut is not a good, it's a service.
- Getting a car fixed is buying a service, which means you get taxed.
Provincial Sales Tax
- anything sold in a province gets taxed.
Example:
- used car - no GST
- new car - both GST & PST
Some provinces have HST such as New Brunswick, P.E.I and Quebec. HST stands for Harmonized Sales Tax.
We were given an example to find the Final price of a new computer when taxes are included
EXAMPLE: Dave lives in Nelson, British columbia. How much tax will he have to pay to buy a new computer that costs $2565.00? What will be the final price when taxes are included.
Step (1) Look for B.C tax, PST: (7%) GST (6%)
(2) Find 6% (6/100=0.06)
Find 7% (7/100=0.07)
(3) Multiply the percentage by the cost of the computer:
GST: 0.06 x $2565.00 = $153.90
PST: 0.07 x 2565.00 = $179.55
(4) To find the total tax, add the PST and GST together to get the answer:
$153.90 + $179.55 = $333.45

What we learned in class today, was how to use some techniques in Spreadsheets. It's interesting because the spreadsheets that we used was a lot different from the other spreadsheets we usually use. I also learned how to make a new page on http://cm20sf07.pbwiki.com; Not only do we have our own page as a class, but we also could put our assignments, and we can make our own spreadsheets. We may edit it and publish it so other people may see it. I also learned how to get answers on using basic Formulas to figure out the result of an equation more easily.
For example:
= Sum (B3:D3)
=Average (A1:A11)

In Our class ,we do mental math. Mr.K Gave us a 10 Question to answer. each Question is all about the spreadsheet Except a and 10.Mr.K taught us how to use the BEDMAS some of us know how to use the BEDMAS and some are not for example =4+8*2=20 This is how the answer got.
we should do first multiplication lot stead of addition Because Division or multiplication must be done first before addition division or subtraction.
But if the Question is written in this way =(4=8)2=24
always remember that we should add first the number inside the column before multiply it.

Scribe post, November 13, 2007.
Our class started off with 10 mental math questions as usual. Mr. Kuropatwa tried to explain how to answer the questions while we were marking our papers, because a few students had a little difficulty coming up with solutions. The first question was tricky; it asked us what would appear in the spreadsheet cell if "8*2" was in it. Some students made the mistake of multiplying it together. You'd actually put "8*2" in the cell, because the result of the equation doesn't appear unless the formula has an = before it.
After correcting our mental math sheets, the class headed to the maclab to do some work online. Due to the bad connection, we just ended up doing our homework in the yellow booklets we were given.
HOMEWORK:
+ Page 151 # 1-2
+ Page 163 # 1-2 & 4-7
+ Page 173 # 1-3
+ assignments 1-4 online: http://cm20sf07.pbwiki.com/

Scribe Post - November 12, 2007
Today in class, we began by talking about the lockdown drill that took place this morning. Although it's not part of math, it is still very important. Other than that, we did our daily mental math and I believe that many of us were having difficulties with the problems. Most of us were confused about multiplying the percents with another number. It would be easier if you just find the percent of the number, rather than multiplying them. The answer would still be correct if you multiply both the number and the percent. Why? The thing is, you divide by 100 because the percent symbol means to divide by 100. Here is an example:
25% x 68
50% of 68 = 34
25 % of 68 = 17
OR
25% x 68 = 1700%
1700% / 100% = 17
We also did a quiz, which wasn't too hard. Still, many of us had some problems here and there. The next scribe will be Maximo.

Scribe post, November 9, 2007.
Today's class began with our daily Mental math. The questions were almost like a review of what we already knew about Spread sheets. We were given a little over 5 minutes to answer all the questions to the best of our ability, then we exchanged our papers and corrected them as a class.
After handing in our papers to Mr. Kuropatwa, we went to the lab to work on our spread sheet assignments. There are 9 different assignments posted on the site http://cm20sf07.pbwiki.com/. You can also find this link on the last page of yesterday's slides. Each assignment has its own site, be sure to put your link on the right page.
When you've completed the assigment:
1) Make a final save.
2) Publish your work.
3) Get the link to your work.
4) Comment on the correct class blog
5) Include your link and your name in your comment.
* YOUR NAME IS IMPORTANT! No name, no marks.

Today, we did some mental math. Then we headed to the mac lab and did our first spreadsheet/first assignment.
Whats important in spreadsheets is that you have to follow the directions very carefully, using the addresses like for example, C3 .
Today for our assignment we had to copy what was on the spreadsheet and then we clicked the link that brings us to a written part of our assignment, which we had to follow carefully.
If one 'value', 'label', or 'formula' isn't placed correctly, everything will be messed up.
=) There isn't much we did.

Spreadsheet
Today, Mr. Kuropatwa taught us about creating and modifying spreadsheets:
To make the text or labels BOLD or ITALIC
BOLD - click the letter B in the format toolbar to make it BOLD and click the cell you want to change for example: B1 after highlighted then click the B in the format toolbar
ITALIC - click the letter i in the format toolbar to make it ITALIC and click the cell you want to change for example: D1 after highlighted then click the i in the format toolbar
To make the row longer - click the line between the two rows you want to become longer for example: row A and B there is a line between them click it and drag it to make the row longer
To align the label or the value to center or opposite the default setting - click the align in the format toolbar and choose were side you want to align it for example: from B3 to B8 highlight it and then click the align and choose which side you want it to align
To make the whole row BOLD or ITALIC - just drag the first row you want for example: from A6 to A9 start dragging A6 to A9 and after highlighted click the B or i in the format toolbar
To make the value a dollar amount - click the format in the format toolbar and then choose the one with the dollar sign for example: the cell D4 to D8 you want it to change to dollar amount highlight it and click the format in the format toolbar and then click the one you want to use
To make a border - click the icon that is a box that are divided into four for example: you want to make a border from A1 to A7 highlight it and click the icon boxes that are divided into four
To color the cell - click the icon that is a box that are divided into four and has different color inside the four square for example: you want to change the color of cell B1 to B5 highlight it and click the box that has different color inside the four square and choose the color you want and thats it

I learn the other is how to find the wages and salaries, it sound hard when firts studied it. but its not, If you atten in class irregular,that will be really hard, so I'am attending the class regular,so I its not hard for me and i learn this lesson very well because I attentd the class regularand especially the technique and style of teaching of Mr. kuropatwa.
In this lesson,I leanr lots of things ang technique for example: find the gross pay of a works work 46 hours this week. he paid doble time for every overtime he work. His regular hours per week is 40 hour and He paid $8.00 per hours.
* find the over time hours by subtracting the Total hours to the Regular hours 46 hour - 40 hour =6 hour (overtime pay)
* find the over time pay by multiplying the overtime hours to overtime rate and to wage
6 hours times 2 tmes $ 8.00 =$96.00 (overtime pay)
* find the regular pay by multiplying the regular hours to waege
40 hours times $ 8.00=320(regular pay )
* then last add the overtime pay and regular pay to get the total gross pay $320.00 add to
$96.oo=$ 416.00 this is the <total grosspay >

net pay
Today we started the class in grouping and we got three problem to solve the title are Summer Wages, everyone has to pay their dues, and what does Mary Rose take Home.
I want to show the solution of this problem "what does Mary Rose take home", I found this problem is to helpful to me I hope you guys do to.
This is the problem and solution..........
What Does Mary Rose Take Home?
Mary Rose works part time and is paid $500.00 gross pay semi-monthly.For her wages she estimates her CPP contribution to be about 3% of her gross pay, her EI contribution to be about 2% of her gross pay, and her income tax about 20%.
(a) Find Mary Roses' estimated total deductions and net pay.
(b) Find Mary Roses' actual total deductions and net pay.
a) 3%/100%=0.03 2%/100%=0.02 20%/100%=0.2
0.03 * $500.00=$15 0.02*$500=$10 0.2*$500=$100
CPP=$ 15 $ 500 b) $500 $500
EI=$ 10 -$ 125 CPP=$ 17.53 -$140.33
FT=$ 100 ______ EI=$ 66.80 _______
_______ __________
$ 225 $140.33
