today we had a test which contains mean, median, and mode,probability,and square root.


this are some of the example that we have on the test:
square root

√22 = 25 - 16= 9 6 /9
22 - 16= 6

√34 = 36 - 25= 11 3/11
34 - 25= 9


mean, median, mode

24 38 36 78 53


24
38
36
78
+ 53
229


probability

red 8 (gray,yellow)
black 4
gray 3 10/22 10÷22=0.454 x 100= 45.4%
yellow 7

well this is my scribe for today.......

today we had a test in math and after the test Mr.Hanley teach us a new technique on how to find the denominator of a square root and then Mr.Hanley give us a example.

1-4= /3 so you subtract the smaller perfect square to the larger perfect square.
4-9= /5
9-16= /7

81 182........100
100-81= /19

And then after that he asked us what are the steps for doing this, and then Jannah answered:
1. Find the perfect squares on either side of the square root you are trying to solve.

2. Subtract the smaller perfect square from the larger perfect square.

3. Answer is your denominator.

Mr.Hanley give us this questions to answer:

Estimate each Square Root using FRACTIONS.
/67 /45 /15 /39 /57 /23

/31 /79 /8 /99 /86 /739

/666 /578 /433 /176 /333 /260

A farm has 7 equal square fields with a total area of 616 acres 2. Estimate the dimensions of each field using fractions.


In the afternoon Mr.Hanley give us back our quiz #1 and we have to do the corrections. After we did our corrections, we did our quiz #2 at the back of our paper, and when we finish our quiz he asked us if we have any questions on what were doing and nobody answered. And Mr.Hanley give us a word problems for homework.

Square Root Word Problems
a. Surinam, in South America, is roughly shaped like a square. It covers an area of about 100 489 km2. Find the length of each side of Surinam.

b. A warehouse has an area of 5808 m2. It is divided into 12 equal square sections. Find the dimensions of each section.

c.Estimate the following square roots using fractions:
/78 /189 /90 /34 /125

/145 /66 /218 /756 /867

/493 /555 /389 /678 /299

well that's my scribe post for today thank you for reading it

TODAYS SCRIBE BY IAN ABAD

Ladies and gentlemen I would like to tell you my scribe.So please read it carefully.

today, we study how do to estimate the square to a fraction.And this is it start.

When we start the class MR. HANLEY the tallest guy in the room asked as to solve the square root of 110.

so I solve it like this:

/100 /110 /121

100 and 121 are the perfect square between 110.

the factors of 100 is 10 so the square root of 110 is 10.?.

When we finish solving it, MR. HANLEY asked us if do we had any ideas to estimate the square root.

when Jamie told him other idea,he told us the main topic of the subject today, HOW TO ESTIMATE THE SQUARE TO FRACTION.

and he asked to solve these:

and i solve it like this:

and then he asked as to solved the square root of 19 by fraction

and this is how i solve it:

/16 /19 /25

I look for perfect square between 19.And I found 16 and 25.I did it by looking for perfect square chart.Then I look for 19 and 19 is the 3rd square after 16 so the numerator is 3 then i look for denominator by counting 17 to 25 and the denominator is 9.the last i had to find the whole number by looking to the perfect square chart and i found that 16 is the 4Th perfect so 4 is the whole number.

so the answer is 4 3/9.

and this is our homework today:

find the square root by fraction.

/9

/10

/11

/12

/13

/14

/15

/16

thank you for reading the royal scribe of Ian. :p

and the next scribe is Kristian

ha ha ha I'm done.

there are some mistake in my first one so I correct it.

November 7 scribe notes by Jorel

today we learned the perfect square. we looked at our perfect square chart, and answer this questions:
find the square roots of these number and is it perfect or not:

1) 25 = 5x5 perfect square
2) 89 = 9.?x9.? not perfect square
3) 64 = 8x8 perfect square
4) 225 = 15x15 perfect square
5) 169 = 13x13 perfect square
6) 784 = 28x28 perfect square
7) 625 = 25x25 perfect square
8) 49 = 7x7 perfect square
9) 594 = 24.?x24.? not perfect square
10) 121 = 11x11 perfect square
11) 765 = 27.?x27.? not perfect square
12) 429 = 20.?20.? not perfect square
13) 654 = 25.?x25.? not perfect square
14) 6 = 2.?x2.? not perfect square
15) 333 = 18.?x18.? not perfect square
16) 852 = 29.?x29.? not perfect square
17) 199 = 14.?x14.? not perfect square
18) 841 = 29x29 perfect square

A warehouse has an area of 2940 meter square. It is divided into 15 equal sections. Find the dimensions of each section.

2940x2940 = 8 643 600

8 643 600 / 15 = 576 240

Each section has 576 240. The square root of 576 240 is 759.1 so its not perfect square

Perfect does not have decimals

tomorrow's scribe isssssssssssssss Ian

Kyle's long overdue Scribe Post!!

kk mr.harbeck dont get mad at me for not really knowing how to post something so im gonna put my scribe here.

The first part of class we pulled out our homework from yesterday. After we used these tiles to try to make a square out of 10 tiles.
But no one can do it until Mr.Hanly showed us how. He showed us that if it is 4x4 so that would make it a perfect square but if we had to do 3x3, We wouldnt be able to make it perfect, so we give it a mullet. Like if it didnt have enough to make it perfect, it would get a mullet.
For Example:

1.1x1
2.2?x2?
3.3?x3?
4.4x4
5.5?x5?
6.6?x6?
7.7?x7?
8.8?x8?
9.9x9
10.10?x10?

New Numbers for homework.
12,14,17

Make squares out of all the numbers

November 3rds Scribe Notes

These couple of days in math we have been learning about Perfect Squares. A perfect square has whole number factors,( no decimals ) the factors are the same and it has equal sides.



Why is this a square perfect? This square is perfect because there are 3 going across and 3 going down. So this square is a 3x3 square. There is an easier way to write this though. Another way is 3 to the power of 2, or 3 squared, or 3 with a small 2.


Numbers like 1, 4, 9, 16, ect. Can be made into perfect squares. These numbers have something in common. They have whole square root numbers.

What is a square root? The square root is a number multiplied by itself giving you the square root of a number. For example: The square root of 25 is 5 because when you mulitiply 5 by 5 it gives you 25.

Try it on your calculator. The symbol should look like a division sign( usually you have to use second function) then punch in the S.R. sign then the number 9. What does it give you? the number should be 3 because 3x3=9. So the square root of 9 is 3.

What if the number can't be made into a perfect square? Mostly all numbers can be made into a perfect square. For example if i want to make a square out of 6. This is what you probably would get.



Is this a perfect square? Ask yourself these questions. Does it have equal sides? Does it have the same factors? Well, you can turn this rectangle into a perfect square. First try to make the largest perfect square you can make, it's ok if you have remaining


squares. This is what you should have.




Now, you have a perfect square. But what do you do with the remaining 2 squares. You must now think of the 2 squares as just pieces that you can put around the square. Like this:





Now, imagine you take one half of the 2 saquares and put it horizontally on top the the square and the other half next to the square vertically.






What do you get? You should get something that would look like this

The squares that you add become the Mullet of the square. The mullet is the remaing squares. Instead of having whole factors they become whole factors with decimals. The mullet is added to squares that do not have whole factor numbers. You can think of the mullet as hair. The more remaining squares you have the longer or bigger the hair(mullet) gets. The less remainders you have the smaller the hair(mullet) is. So the measurments of a perfect square with an area of 6 is 2.44x2.44 or 2.44 to the power of 2.

Mr. Harbeck gave us a test on probability and mean, median and mode, so if you weren't here on that day you will probably take it the next time we have class.

Assignments

He also assigned an assignment dealing withe perefect squares. We were given 2 sheets of graph paper and 1 long white peice of paper. You where so post to make perefect squares from 1-16. Four of the squares would have no mullet(1,4,9,16) the rest would have a mullets. If you weren't sure how to paste them onto the paper you could save the squares(ready to paste) and wait till next class.


I'll show you how to get started. This is what the first part should look like this




you have to write the factors, the exponent and and what the area of the square is.

Assignments that are due.
Perfect sqaure chart-three columns(factors, exponent, area) e.g. 25x25, 25 to the power of 2, 625 unit squared.
