Lance's Texbook Scribe Post (4,10,15) Pythagorean

4) Estimate the square root of each number, to one decimal. Check with a calculator.

a) 72 b) 103 c) 55

10. Kai uses an entire can of paint on a square backdrop for the school play. The label on the can states that one can cover 27 m² of wall surface. Estimate the backdrop's side length, to one decimal place.

.

5x5=25 and 6x6=36 so it should be between the numbers 5 and 6. 

5.2x5.2=27.04 then it move it up into one decimal place which is 5.3

15. Order the following numbers from least to greatest: 7, square root of 46, 5.8, square root of 27, and 6.3. 

 5.1, 5.8, 6.3, 6.7, 7

1) Answer in a short paragraph with diagrams

2. Solve for the missing side length.

3. Is this a right triangle? Prove it!!!

This is not a right triangle because 100 cm does not equal 121 cm

Alex's post on pay it forward

Pay it forward was made by a kid named trevor, in his geography class and his assignment was to create a thing that can change the world and his idea was to help three people and the three people will help three other people and so on.

Me Philip and Lance's act of kindness was to clean the community by picking up garbage we saw.
We Chose this activity because we like walking around and our community is full of really nice people. We helped by making the place look cleaner and keeping crime away because Mrs. Wilson said when you clean up you keep crime away.

My act of kindness went pretty well because we cleanedI felt happy because I was cleaning the place I lived in ever since i was born

I think pay it forward is important because i would like to live in a better place when i'm older with more friendlier people

Lance's Graph Post

1)Bar Graph:
Advantages: The advantage of this graph is having not to change the data to a percent or other things
Disadvantages  You will need to make the intervals equal              

Double Bar Graph:
 Advantages: You can compare two sets of data together
Disadvantages: You will have to make the intervals equal

Circle Graph:
Advantages: You can compare sets of data using a percent
Disadvantages: You will need to change the data to a percent

Line Graph:
 Advantages: You can show the data changing over time
Disadvantages: You will need to make the lines straight and intervals equal

PictoGraph:
Advantages: You can show sets of data that is like a bar graph
Disadvantages: You can mess around with the data to make one look larger

2)Make one of the bars larger than the other










Break in the y-axis








Color one differently












2A) I would use bar graph and line graph to show this information accurately
2b)Yes I would continue because it shows that every week the sales are increasing which means the trend is going up

4)If i were to convince Mrs. Mota I would choose the line graph because it shows that the trend is going up which means that the sales of healthy food choices are increasing or decreasing

4a)For the Line Graph I would change the intervals so instead of going up by 5 I would go up by 2 to make the trend look like its increasing more
For the Pictograph I would change what the amount of 1 heart is so instead of 1 heart represents 4 sold I would make it like 1 heart represents 2 sold to make it look longer
