Hi it's Alyanna :) Well I dont really have anything to scribe about.. But today in class we we're in the computer lab. Its been awhile .. In the lab we got this question.. which i'll try to remember because I didnt bring my binder home today. Fail -_-"
Simran charges a flat rate of $15 per call plus an hourly rate of $3.50. Liem charges $10 per call plus an hourly rate of $4.25. How long of a call would they charge the same amount?
So, we were suppose to graph this question on Excel. I would show you how but unfortunetly I don't have it. -_-" I use to but since my computer got upgraded.. It disappeared. Sorry guys, I'm a fail -_-"
Well, thats practically all we did in class. We also got our Stash-its back! Its about time... AHAHA. ^_^
We ended the class by going on www.mathplayground.com , and played Saving the Zogs. Tehehe :) Well that's all, bye guys !

Scribe Post :)

Hey, Hi , how you doing? Well Mr"B" just called and told me to do the scribe. Because again.. I forgot -_-" Anyways, I'm doing a scribe from way back when... Remember that video we watched? Well it was talking about Similarity and Proportions ..
If we were to flip the shape around we will see if they truly are congruent to one another.
The first angle we are looking at is equal or corresponding to its other angle.
If we do that to all the other angles, they should all be the same as there corresponding angles.
btw: 01 = 10 and 81 = 18
All the angles match their corresponding angles they are congruent.
So at least for the angles of the shape they are equal. But now we have to look at the sides..
For the sides they have to form a proportion. You can find the proportion in several different ways. I'll show you one way.
btw: 01= 10 and 81 = 18
We can compare to get a proportion. So i'll call 18 and 13.5 side A, and i'll call 10 and 7.5 side B. Then we could compare 18 and 13.5 ( both of the side A's). So now we want to see if thats congruent to 10 and 7.5 (both of the side B's). They are congruent to each other. Because if we divide 18 and 13.5 we get 1.3 repeating and if we divide 10 and 7.5 we also get 1.3 repeating. So the two ratios represent the same amount.
So these figures really are similar because there sides are proportional.
If we tested out the other sides we'd see the same thing. 8 to 8 is the same thing as 6 to 6 because they are all representing a ratio of 1.
Well thats my scribe! :) Wow, I acutally understood things while doing this -_-". Backe, I hope youe happy! AHAHA :) see you guys soon ♥ oh and tell me if have mistakes!!! :D
Similarity and Proportions aren't very hard to understand.
Similar Figures have corresponding (matching) angles that are congruent (equal), and their corresponding (matching) sides are proportional.
I'll try and explain this using a picture..
The green markings indicate the size of the angle. The blue cirlces are congruent to each other but they are NOT congruent to the others because they are all different.
Similar Figures - They have to have matching or congruent angles that are equal.
If we were to flip the shape around we will see if they truly are congruent to one another.
The first angle we are looking at is equal or corresponding to its other angle.
If we do that to all the other angles, they should all be the same as there corresponding angles.

Mr.Backee,
My deepest sympathy, I'm sorry for your loss. I hope you and your family can pull through. Always remember your second family is in Sargent waiting for you to come home. We got you :) through thick and thin. Hang your head high, not low. People come and go, just remember its part of life. I know how hard it is to lose someone so close to your heart. I've had it happen several times already. But what i learned is no matter what happens they'll still be here with us. Living in our hearts. Smile Backee :) It's what your brother and father in law would want. I know this is a bad time but Merry Christmas and Happy New Year to you and your family! Love you Backee :) ♥

Numbaa 19 :)
Sunday, November 29, 2009
Hey guys! :) Sorry this is late, I haven't been home in a while. HAHHA, don't chop my head up "Mr.B" Anyways, I got number 19 for my post thing.
I got the answers by using that a+b=c method we learned.
c) 8/13
d) -1 1/2
I don't know how to show C and D. I need to ask "Mr.B" for help. I'll have it up tommorrow :)

Hey guys! :) As if I was chosen to do the scribe.. AHHH. Anywho today in the beginning of class we went over our homework. People asked about #9 and 10.. "Mr.B" answered the questions for everyone to understand.
Number 9 was 2+ (-3/8) :
This is how to get the answer. I'll explain it, if you don't get it. K, remember mathmaticians or whatever are lazy. They dont put that 1, so I added it in. After that you need to get the common denominator. We can use 8 for both. So how do you get that number 1 to become a 8. You multiply it by 8 and then you do the rule, you know the rule. Whatever you do to the bottom you do to the top. I multiply the 2 with 8 and get 16. Which makes the original 2, 16/8. You leave -3/8 as it is, because the denominator was already 8. So you dont need to multiply anything. Then you take both numerators and add it, 16 + (-3/8)= 13. So you get 13/8, you leave the denominator as it is. After that you make it a mixed number. How many 13's go in 8? Just 1 then 5/8 will be left, so your final answer is 1 5/8.
Number 10 was 9 1/8 + (-2 1/3) :
To get this answer. You seperate the mixed numbers. Then you add 9+(-2) which is 7. After you must find the common denominator for each fraction. You do that by multiplying 8 and 3. The two denominators, and when you multiply the two you get 24. Then the rule kicks in, whatever you do to the top you do to the bottom. For the first fraction I get 3 from multiplying 1 and 3. Then I get -8 for the second fraction because I multiplied -1 and 8. After that you add 3 + (-8) the two numerators and you get an answer which is -5. The denominator stays as 24. Then you add 7 with -5/24 and you get the final answer of 6 19/24.
After we talked about the two questions that some people had difficulties on, "Mr.B" gave us 3-4 minutes to check are homework with someone.
We then moved on to SUBTRACTING FRACTIONS!! "Mr.B" told us to show how to subtract proper, improper and mixed numbers. We needed 2 examples, my 2 examples are...
Proper - 2/4 - 1/9 = 18/36 - 4/36
= 14/36
Simplified = 7/18
3/4 - 5/8 = 6/8 - 5/8
= 1/8
Improper - 14/7 - 16/9 = 126/63 - 112/63
= 14/63
Simplified = 2/9
9/3 - 11/5 = 45/15 - 33/15
= 12/15
Simplified = 4/5
Anywho, we had some homework. This was the homework for today! :) I hope you guys finish.
Homework:
1) -6 1/3 - 3 2/5
2) -4 7/9 - (-2 1/18)
3) -64/13 - 32/26
4) 17/18 - 4/9
5) 4/5- 3/4 - (-2/3) - 1/2
6)-8 - 1 1/4
7)-4 1/4 - (-5/2)
8) -(-2 1/3) - 4 1/6
9) -(-9/4) - (-4/9)
10)7/8 - (-5/6) - 3/4 + (-1/2)
I'm done now! :) Tah Tah for now! AHAHA, oh and I'm sorry this is so late. I had practice til 7 and I had to go somewhere afterwards! :)
