Pictures Linked?
- Pythagoras is a well known mathematics Guy. He is the one that made the math call Pythagoras, with the square roots and angles with the Triangle and squares. It also involves with the A² + B² = C².
- This picture is linked to the Pythagoras because Pythagoras solves the angle,area or the perimeter with the A² + B² = C².

- This picture has to do with the square, because triangles are half of the squares. Also you can also find the area with Length and width.

- This is the thing where you can find the Hypotenuse of the Triangle.
R.A.T - Its a short way of calling Right Angle Triangle
Hypotenuse - It is the longest side on the Triangle and its the opposite side of the right Triangle
Legs - The shortest side of a triangle. Comes out of the right angle and the triangle always has 2 legs.
Theorem - It is A² + B² = C²
Greek - Pythagoras is an ancient Greek person.

Today in class we went over our Math homework from the pink thingy he gave us. After doing all of those stuff he gave us a homework to practice for our test/quiz tomorrow. i will list all of them and i will answer four of them.

here are all of them :

1) N-6 = 14


2) N+9 = -4


3) - 9 + n = 17


4) 25 = - 12 + n


5) N - (-6) = 15


6) -N/3 = 6


7) -30 N = 120


8) 1/4 N = 12


9) - 1/3 n = 10


10) 12 N = 48



the questions with the slash in them are suppose to be horizontal because it's being divided by.

Here are the Four that i will answer

Here is my first one


n+9=-4

n+9-9=-4-9

n=-13

n+9=-4

13+9=-4

-4=-4


Here is my second one


25 = -12+n

-12+12+n=25+12

n=37

-12+n=25

12+37 = 25

25 = 25


Here is my third one

9+n=17

-9+9+n=17+9

n=26

-9+n= -17

-9+26= -17

17=17


And here is my Last one


n - 6 = 14

n [-6 + 6] = 14 + 6

n = 20

n – 6 = 14

20 - 6 = 14

14 = 14


Everything i answered might be wrong so just comment. Be ready for the test tomorrow study, these scribe might help so read it. And that's about it . For the next scribe i choose no one yet because i dont know who didn't do it yet . Or am i suppose to choose anyone? Anyways study and comment please!!!

In class we watched the movie "Pay it Forward", it is about a person that believes that just one person can make a difference. After watching the movie, we were asked to do a random act of kindness over the holiday's and ask them to "Pay it Forward". I was thingking about shoveling so two days before new year me and Andrew chose to go to my friends house. then me and Andrew started acting out some kindness by shoveling our friends yard. Like Andrew said it was cold that day but me and Andrew still chose to Pay it Forward.












1) Who are you going to help?
2) What are you going to do?
3) Where are you going to do this?
4) When are you going to do this?


I felt happy that I helped my friend shovel his yard. So you ask if one person can make a difference, my answer is yes! it doesn't have to big as long as you do something good and it makes the person happy and might even do it for someone else.

1) Who are you going to help?
2) What are you going to do?
3) Where are you going to do this?
4) When are you going to do this?

During class we watched a movie called pay it forward. a story of a young boy attempts to make the world a better place after his teacher gives him that chance. so our assingment was to act out some kindness.

The task i chose is shoveling. two days  before new year me and kareel chose to go to my friends house. then me and Kareel started acting out some kindness by shoveling our friends house yard.

It was cold that day but me and kareel choose to pay it forward. I beilive that making a difference is one of a good kind act and i believe that everyone can make a change.

hope you have a blessed and a Happy New Year..!

Mr.1 : Good morning class

Mr.1 : Where is everyone else

Naruto : They skip school and went trick or treating sir

Naruto : That's why im dress like this because it's halloween sir

Mr.1 : Okay anyways

Mr.1 : Do you need any help from yesterday's homework Naruto?

Naruto : Actually yes sir i do

Naruto : is the answer negative6 n+15? for question n+3minus5+12

Mr.1 : actually it is wrong the answer is negative4n+15

Naruto : How did you get that?

Mr.1 : First you regroup it so that the variable is with the variable like this and 5n+12 then i added the varriable and plus negative 5n which equaled 6n because the n is still counted as a number then i added the posivitive 3 to positive 12 which was 15 so my answer would be -4n+15

Naruto : oh okay i get it now

Mr.1 : do you have anymore work that you dont get Naruto

Naruto : um question #2 is the answer 12n+10?

Mr. 1 : actually it is not wanna answer it again?

Naruto : sure

Naruto : well first i rearange the positive 2

Naruto : then i multiply the four to the brackets then i multiplied 3 to 8 which equaled to 24

Naruto : then the 2 at the end to the 24 because it has no variable and equaled to 26 then the answer of 12n+26

Once upon a time there was a guy named Pork who is a terrorist. He is in a war and while he was walking slowly he found his friends and there all dead he kept walking and walking and walking until he encounter a police named Beef.Beef said i will let you run away if you answer this integer question.But Pork do not know anything because he didn't barely went to school.Pork said here is the integer question (+5)+(+5) = ?Pork used his bullets to answer the integer question. He said the answer is +10.Beef let him run away and he said when i see you next time i wont let you go.Then pork Started running then he stopped well because he's tired and then he started walking.



While he was walking he saw a zombie and he killed it

He doesn't have enough bullets so he have use a integer question to have enough
(+10)+(+10)=+20 so he save 10 more bullet in case he ran out.After answering an integer question he stopped to eat lunch but when he was eating lunch he saw Beef again Beef said you have to answer this integer question or else i will kill you.(+12)+(-16)=? and he said (+4)Beef said HA! its wrong the answer is (-4)now i am going to kill you then Pork started shooting him

Then Beef started shooting too did Pork died???

Today in class :

We had to answer the questions from the math textbook.

I have to do question # 5 so here it is.


5. Raoul spins the pointer on each spinner. Find the probability of each event.

The total possible outcomes for this problem is 10 (5x2=10)

a) Green and A2

The answer for a) is 1/10=0.1. 0.1x100 = 10%

b) Red And an even number

The answer for b) is 2/10=1/5=0.2. 0.2x100 = 20%

mean

Put raw data into ascending order
Add all the data
Divide all the sum by how many the data is



Median
Put raw data into ascending order
Median is the middle number
If there is two middle numbers add them up and divide them by 2







Mode
Put raw data into ascending order
The mode is the most common number
you can have more than 1 mode
And no mode at all




Range
Put raw data into ascending order
Large data minus the smallest data
the answer is the range



Here Is a video explaining mean, median, and mode
