Scribe 5.

I have to do questions number: 18 and 20 and 22 on page 86.

Alright, let's get started. (:

Question #18.




If you can't really see that, the question states.
A floor mat for gymnastics is a square with a side length of 14. What is the area of the floor mat in square meters?
One of the methods that you can use to find this problem out is:
Drawing it.



So, It said a side length is 14, right.
So we would show it like this:

So.
This is the formula to find the area

.

If you can not read that, or unable to read that.

The formula is:

SxS=A
14x14=196

196=Area

A=Area.

S=Side.

So the answer to question 18. -

A floor mat for gymnastics is a square with a side length of 14. What is the area of the floor mat in square meters?

is - 196 metres squared.

Question 20:

If you don't like how it says. It states:

Adam’s uncle has instructions for building

a shed. One page of the instructions,

shown below, is not very clear.

a) What is the area of the rectangle?

b) What is the side length of the square?

The formula to get the area is :

Or in another form.:

SxS=A

4x9=36

36=A

A=Area
S=Side.

What is the area of a square:

The area of a square is: 6 cm

Question 22:

If you can't read that , it says :

The world’s largest city square is

Tiananmen Square in Beijing, China.

It has an area of 396 900 m2.

a) What are the dimensions of the square?

b) If the square had dimensions of 629 m

by 629 m, what would be the area?

c) If the square had an area less than

394 000 m2 and greater than

386 000 m2, what are all of the

possible whole number dimensions

that it could have?

I looked and looked and asked many questions, but I do not know how to get the dimensions, I am very sorry about this, but I can not find it anywhere, I am very very sorry.

Scribe 4

I chose to do #4 and it is questions 17,19, and 21.

17. Use prime factorization to figure out if 54 is a perfect square.

The answer is...

No. 54 is not a perfect square.

19. Find the distance that the students ran. They ran around the field twice.

They ran 1360m.

21.Kate wants to put a patio in her backyard. The patio stones have an area of 1m.She created this design.

a)What is the area?

56m2

b)What other possible dimensions are there?

There is 7 by 8 and 28 by 2.

c)Can you make the patio in to a square?Explain.

No.

Scribe 6

I chose number 24 and 25.

24. The first three triangular numbers are 1, 3 and 6

a) What are the next three triangular numbers?
The next three triangular numbers are 10, 15 and 21.

b) Add together any two consecutive triangular numbers. What do you notice about the sums?
I noticed that the sums are all perfect squares.


25. A square digital photo on the computer has an area of 144cm2.


a) What is the side length of the photo?
The side length is 12cm because the square root of 144 is 12.


b) The photo is enlarged so that the side length is now 36cm. What is the area of the enlarged photo?
The area is now 1296cm2 because 36x36=1296cm2

c) How many times as large as the original is the enlarged area?
The enlarged area is 9 times as large because 144/1296=9 (There is more than method to find this answer, I use division.

d) How many times as large as the original is the enlarged side length?
The enlarged length is 3 times as large because 36/12=3.

e) Use what you know about the square root of a perfect square to identify the relationship between the numbers in parts c) and d).
Question d) is the side and question c) is the area. When you square the side you get the area. So 3x3=9 .

Here is a video of how to find the square root of a number.







Please comment if you see any mistakes or any ideas to make it better.

Kevin's Sesame Street Video Post

The people in my group were Richard, Tyler, and me.

Rate - Compares two quantities measured in different units.

Example - 72 beats per minute or 75 beats/min is a rate.

Ratio - Part to Part Ratio compares different parts of the group to each other.

Example - A's to B's which is 3 to 4

Proportional Reasoning - A relation ship the says that two ratios or two rates are equal.

Example - How much will 12 erasers cost if 3 erasers cost 75 cents?

So 12 eraser cost 300 cents or $ 3.00.

Sadly, Neither me, Richard , or Tyler could find the video on YouTube.

So here's the link

Now here's the fun part :P, a video of me and Tyler's horrible acting.

Rate- Compares two quantities measured in different units.
Example $10 per 100g

Ratio- Compares two or more quantities measured in the same unit
eg. apples to oranges, 2:3

Porportion- A relationship that says that to ratios or rate are equal

Rate - Compares two quantities measured in different units
Example - $1.09 per 100g or $1.69/100g


Ratio - Two term ratio compares two quantities measured in the same units
Example - 7:20 or 7 to 20

Proportion Reasoning - A relationship that says that two ratios or two rates are equal
Example - $3.00/12 erasers
