Today in class we started a new unit thingy called Pythagoras.

In this unit we start off with circles and 90 degree angels. We wrote everthing in our blue foldables:

-A circle equals 360 degrees

-A circle split into quadrants, each angle equaled 90 degrees

-In a right triangle the square points to the hypotenuse, shown in the picture. The hypotenuse is always labelled c and it's legs are labelled a + b

-In many cases the right angle will have it's legs labelled a + b and the hypotenuse is always labelled c

-Here is the picture of a rectangle with 2 right triangles in it. Since the area of the rectangle is a x b, the area of the right triangles inside is 1/2 of (a x b) e.g if the area is 12 then the area of the triangle is 6... this will lead us to our theorem

-So the area of a square would be a x a which would equal a (squared)

The Pythagorean Theorem:

The pythagorean theorem states that the legs a + b and the hypotenuse obey the following theorem: a (squared) + b (squared) = c (squared)

That was pretty much it :)

would you want 5 dollars a day.
OR
1cent double a day.

At first i wanted 5 dollars a day because in one week you'll have 35 dollars and if i take 1 cent double a day you'll have $2.56 for a week.
and 5 dollars a day would get you 150 dollars per month.


PROVE WHO IS RIGHT. (:

to prove who is right you need to know how much $ per month which is 30 days. (:

a cent double a day. well equal about 2097152000 pennies and if you put that in dollars it well be 20971520 dollars.



For the table in the left you need to multiply 5 to the days. By multiplying the days to 5 you'll get the answer for that day. example ; [ 1 x 5 = 5] [ 2 x 5 = 10] . . .



HOMEWORK. (;
the graph needs ;
a title ,
x axis,
and and y axis, (:

the homework is to fill out the graph thingy. the first 15 ? haha (: idk .(: well yeah thats my scribe :P

The Question:
The frist step:

7 x 2 + 1 =
You will get an improper fraction.
Now use reciprocal as one of your

strategies to solve this problem.

Just switch the denominator with

the numerator to get 2/15.
I wrote 40/1 because all whole

numbers are out of 1. Multiply 40/1

by 2/15 and that will = 80/15.

Since this is an improper fraction

you need to make it proper.

To get a proper fraction see how

many times the denominator

goes into the numerator. Your ending

fraction should be 5 1/3 ( already simplified)

Today in class we....

Learned to do easier ways for dividing fractions...
Ex. 2/3 / 1 1/2 =?

Mr harbeck taught us....
That when its like that question ^ then we have to make it inproper.
(ex. 2/3 / 1 1/2 = 2/3 / 3/2) so when its like that we can make it inproper and it will be easier to do. so when you make it inproper if you find a pattern like this:

<--- See how they have both the same numbers!!! <--- Then you could change the denominator and put it in the oter fractions denominator. So then you would have 2/2 and 3/3. <--- Or you can just times the numerator and then since the denominator has the same numbers it will equal the same sum as the numerator. so if you times them you get 6/6 which equals 1.


Mr. Harbeck Learned And Taught Us.....


Mr. Harbeck learned and taught us that when you do a question like this:
2/3 /11/2 = 2/3 / 3/2
= 6/6=1 And when you do those kinds of questions you have to line up the first equal signs.. Mr harbeck learned this from Mr. Ralph

For homework we had....

Had to finish that piece of paper that Mr. Harbeck gave to us in class and give examples for rows 4 and 5. In row 3 we had to finish the questions. In colum 5 we had to show recipicals for the fractions he gave us. And for row 2 we had to explain how we did the questions in row 3.

Today in math class, we learned more about dividing fractions.

Mr. Harbeck assigned us some questions for homework:

3/4 / 1/8
5 / 1/4
9/10 / 12
5/8 / 3/10

As you can see, you can use a ratio table to answer this question. After finding out the answer, you have to make it a "reciprocal". Once you find the answer using the reciprocal, you must simplify it in lowest terms.

Whatever you did on one side of the ratio table, you must do on the other side of the ratio table. You do the same thing for this question too. You have to make it a reciprocal. So 5/1 x 4/1 = 20/1.

You can also simply just switch the denominator and the numerator too, like shown in this question. 9/10 was turned into a reciprocal, which would be 10/9. 10/9 x 12/1 = 120/9 You have to simplify this to lowest terms too.

Same thing for this one too, you make 3/10 into a reciprocal. You also have to simplify it in lowest terms.

Reciprocal: When you switch the denominator to the numerator, and the numerator to the denominator.

So today in calss we went over our questions we had for homework on the Smart Board. Those questions were

- 1/5 divide by 2/3
- 1/4 divide by 3/8

- 2/5 divide by 7/10

- 2/15 divide by 1/6

- 4/5 divide by 1/2

That's what we basically did for the first 40 min. Harbeck gave us the rest of the time to try and finish our homework.

Today's questions were

- 8/9 divide by 2/3
- 5/12 divide by 3/16
- 3/4 divide by 1/8
- 5 divide by 1/4

- 6 divide by 4/7

- 1/2 divide by 4

- 9/10 divide by 12

- 5/8 divide by 3/10
- 8/11 divide by 2/11

I'll be doing 8/9 divide by 2/3, 5/12 divide by 3/16, 6 divide by 4/7, 1/2 divide by 4 and 8/11 divide by 2/11

Scribe on four 4s

For # eight i used for fours and i got eight. For nine i used an exclamation mark becuase it is a math sign.

for # 4 i used order of operations and i used a exclamaion mark on # six.

For # 2 i used a order of operations again. the rest were simple.

That is the work we did in class today!
