Jomarie's Pythagoras Growing Post

PART1) A Pythagorean Triple is a right triangle that uses a set of numbers (1,2,3 ect..) that satisfy a2+b2=c2. a=3+b=4=c=5

Another example is 6squared+8squared=10 squared. To prove that:

6 squared = 36 plus 8 squared (which equals 64) = 100 (which is the same as 10 squared)
36+64=100

1x1=1

2x2=4

3x3=9

4x4=16

5x5=25

6x6=36

7x7=49

8x8=64

9x9=81

10x10=100

Part3) Worksheet B

Question:
You've just picked up a ground ball at first base, and you see the other team's player runnig towards thrid base. How far do you have to throw the ball to get it from first base to thrid base, and runner out? The answer is.....

First I drew the picture of the whole baseball field. We know we have to go to first base to third so I ignored the second base, which is seen above and we also know that home to first base and third base is 90 FT (they are the leg). So, we just have to find out what the hypotenuse is. This is how I solved it:

First write the theoream: a2 + b2 = c2, then you can do the rest of the work.

a2 = 90, b2 = 90 and c2 =?

90 squared + 90 squared = c2

90 squared = 8100

8100 + 8100 = c2

8100 + 1800 = 16200 = c2

square root of 16200 = c2 = c

square root of 16200 = 127.27 or 127.28 when you round.

and in fractions it = 11 6/23

PART4) My own question.

There was this waterslide that is 4m tall and the base of 6m. The water is 3m high and the water touches the base of the slide at the exact same level. If you were to slide down from the top of the slide and going down to the water, how many meters is it from the top of the slide to touching the water?

Question 1
Use this picture and reflect on your the puppy kibble test.

1) What strategies were needed?
The stratagies that were needed were a ratio table because on one side you can put the price and the other side is the cups.

2) How did you use these strategies?
I didnt really do a ratio table but it is similar.
Like for the 12C, we know that 2 2/5 = $3.60 I just kept adding 2 2/5 to get close to 12. Then whatever answer I got to get to 12 by just adding 2 2/5 repeatedly I did the same thing with the price.

3) Or How could you of used these strategies.
You could use these stratagies with many things like fraction problems.

4) How would you figure out the price of a 6 cup bag of Betty's Snack mix? Use a ratio table
If I use the ratio table I would do 12C = $18.00 (from the test) then under it, it would be 6C = $........
What I would do is divided it 12C by 2 to get 6C because we all know that 6 is half of 12. Then we do the same thing to the price, $18.00 divided it by 2 which equals $9.00. There is your answer.

5) Find 3 other values (amounts of Snack Mix) that could be solved using the same ratio table. Find the $$ of your new container sizes.

Question 3





Question 4




Which group gets the largest portion of pizza?
I think GroupD got the larger portion of pizza.

What strategies did you use in finding your answer.
I used the clock way.
