SCRIBE: Dimentions of a Sphere (scale factors)
Hey everybody, in today's class we did some problems one scale factors we also talked a little about QUADRILATERALS - Any 4 sided figure ( Trapezoid, Parallelogram, Rectangle, Rhombus and the Square).
Example :
Length
1:4
Area
1 squared : 4 squared
1: 16
Volume
1 cubed : 4 cubed
1: 64
You also have to remember to indicate your units of measurement and weather its squared or cubed. So for example cm squared, and always remember to show your work.
The slides from today's class are posted below with all the problems we did and the homework assignment.
The next scribe will be RYAN
see yall tomorrow =D

Scribe Post Jan. 19th
We also had a quiz on measurement that everyone seemed to have had a good grasp on because we all good exceptionally high marks. The quiz focused on alot of questions having to do with converting different units of measurements like for instance converting CM into M, and stuff like that. Then there were a couple of questions focusing on the area and perimeter of a shapes, but previous posts have covered that topic.
This is Jonathan by the way, and Mark already picked the next scribe.

HI YA'LL!
So we've just learned about how to measure Volume of the late, and in Fridays class we learned how to measure the Surface Area.
S.A (surface area) =4(pi)r-squared
This means in order to find the surface area of any object you multiply 4 by pi (3.14 repeated). Then you multiply total of 4xpi by the surface's area's radius (which is the circumference divided by 2). BUT YOU RADIUS IS ALWAYS SQUARED! If you do not square you radius your answer will be totally off.
that's pretty much it :) .... remember to check out the link that follows to study for exams!

Volume & surface area of spheres
Hello
We talked about Volume & Surface Area of Sphere.
what we did today is do some questions about volume and surface area, we also looked over the Conversion Table witch showed different measurements converted to other measurements, but the one's that we mostly looked at were 1 inch = 2.54 cm, and 1 mile = 1.61 km.
We first got put in groups of 3 and worked on the questions together.
One question that we did was " A car handbook calls for the oil to be changed every 5000 km, how many miles is that ?
( 1 km = 0.621 mi )
what i did was i used the hint that they gave, and i changed the 1 km to 5000 km, then i multiplied it by 0.621 mi, because every 1 km = 0.621 mi. So then i got 3105 mi for how many miles it had to be before changing it.
When we were done doing the questions, we also got an assignment to do for home work, witch was Pg. 34 and questions # 1 - 5.
Next Scribe is ..... Jonathan!!
because he had to go to somewhere "important" hahah jk bro |^_^|

CONVERTING MEASUREMENTS, ESTIMATES AND CONVERSIONS =)
hey there?!
Last Tuesday and Wednesday we talk about the estimates and conversions.
We also talk about a technique to be easy to know the conversion.
For example:
- KING = KILO
- HENRY = HECTO
- DIED = DECO
- MOTHER/ LADY/ GRANDMOTHER = METER/ LITER/ GRAMS
- DIDN'T = DECI
- CARE = CENTI
- MUCH = MILI
convert 500mm to feet: 500mm x0.03937= 19.7 inches, and there are 12 inches in a foot , so 19.7/12=1.64 feet ( or 1 foot and 7.7 inches).
how did i get the 86500. the first thing i do is i look at the king Henry died mother didn't care much the MNEMONIC. I move the decimal point to the right to get the 86500. if you dont get it just used the mnemonic to see how many zero your going to put.It always has a smiley faces. The most important thing that we should remember is the conversions of the imperial and the metric measurements. do you know that the imperial and the metric system are different. The imperial is complicated than the metric. The main difference between metric an imperial (American) system of measurements is that the metric system is a breeze to use, and all the scientific measurements are given in metric. Since it's a system based on 10, every measurement is divisble by 10, in terms of scaling up and down. In other words, a yardstick is divided by 36 inches. A meterstick (about 39 inches) is divided into 100 parts. So, if you need to convert centimeters to meters, you just multiply by 100. (Instead of yards to feet, or feet to inches)
This are the conversions of imperial and metric:
Imperial/USA unit | Metric (SI) unit | Metric (SI) unit | Imperial/USA unit | |
Ounce (weight) | 28.35 grams | Gram | 0.035 ounces | |
Pound | 0.45 kilograms | Kilogram | 2.21 pounds | |
UK ton (2240 pounds) | 1.02 metric tons | Metric ton (1000 kg.) | 0.98 UK tons | |
US ton (2000 pounds) | 0.91 metric tons | Metric ton (1000 kg.) | 1.10 US tons |
Imperial/USA unit | Metric (SI) unit | Metric (SI) unit | Imperial/USA unit | |
Inch | 2.54 centimeters | Centimeter | 0.39 inches | |
Foot | 30.48 centimeters | Meter | 3.28 feet | |
Yard | 0.91 meters | Meter | 1.09 yards | |
Mile | 1.61 kilometers | Kilometer | 0.62 miles |

jan 12 .An easy way to remember the metric system is too think king, Henry, died, mother, didn't, care, much. you just use the fist letter of every word. to convert them for example
2.4cm to mm (you would move the decimal one spaces to the left) and it would then be 24mm
from care to much. If your going from hecta to kilo then you would put a zero in front of the number 2.4 hecto would be 0.24 kilo. sorry i am late yesterdays scribe will be Cachel.

SCRIBE
Today in class we had a pre-test so that we will be prepared for the test tomorrow. This is basically what was on our test....
Our first question was quite easy. It asked us about a profit of a raffle draw and how many tickets would have to be sold so that they would make NO profit. Here's the question:
Students sell tickets for a raffle. If the students sell 500 tickets, they loose $250. If the students sell 1500 tickets they make a profit of $250. How many tickets do they need to "break even" (no gain or loss)
(a) 0 Tickets (b) 250 tickets (c) 1000 tickets (d) 2000 tickets
Well if they loose $250 when they sell 500 tickets when they double how many tickets they sell (1000) they will have no gain or loss. Hence the answer is 1000
In the next question we dealt with an equation and profit. Here's the question:
A school hosts a dance. The profit, P, in dollars, is represented by the function P(n) = 4n - 100. What is n when P(n) = 1400 ?
(a) 325 (b) 375 (c) 450 (d) 5500
In this situation you need to replace the n with one of the given answers (the multiple choice answers) to see what one will give you a total of 1400. So you will multiply ___ by 4, then subtract that by 100 to see if it will give you 1400. When you replace the n with 375 you will end up with 1400. So 1400 = 4(375) - 100
In question 3 I had difficulties and tried to get Ryan to explain it to me so I will try and explain this to the best of my ability. Your given a chart of data about How much money it will cost to rent a apartment (in squared feet). Then we were to find the Linear Regression.
(go to this website to see the chart if you wish)
All in all we were to enter the given data into a list (STAT. ENTER) then graph it (GRAPH). then do to STAT again, but this time were moving over to CALC picking #4, LinReg(ax+b). You enter the normal 2nd. 1. comma. 2nd. 2. VARS. Y-VARS. (select) #1 (FUNCTION). ENTER. ENTER.
We can then find the Linear Regression ! y= 1.16x + 179.8
In question 4 we then worked with patterns. Here's the question:
Helen's starting salary is $35 000 per year. If she recieves a raise of $2000 every year after that, how much will she have earned after working 11 years?
Well if Helen starts off at $35 000 and you jump to $2000 your at $37 000. So for 1st year its $37 000. Then the 2nd year it will be $39 000, the 3rd year $41 000 etc, etc .... And once you reach 11 years you are at $57 000 !
Yet again you enter the list into the calculator as shown above. However when you are at the graphing stage that is when you get your answers. This time you have to hit the TRACE button and move around the arrow buttons until your x axis reads the height you are looking for. Once you have found the height, you look at the y= and there is your answer! You do this for questions b,c,and d.
For question E you are asked about Interpolation and Extrapolation. Interpolation is when you find the value INSIDE (inbetween) the points. Extrapolation is when you find the value OUTSIDE the points.
Yeah, thats pretty much it ... hope this helped :D
NEXT SCRIBE IS ..... Hmmm .... CAITLIN.

Scribe(Escribiente) - Mark Casanova
- Fibonacci Tree
- Definitions
- Arithmetic sequence
- Formula to solve arithmetic sequences
- How arithmetic sequences work
- Solving word problems using the formula for arithmetic sequences.
Alright now we had questions during class and applying it to some questions.
1.
a. What is the next sequence term of the sequence 1,-1,-3,-5,-7....?
Answer = -9
I got this answer by basically adding -2 to the next sequence of numbers.
b. Find an equation that could be used to generate such a sequence.
Answer = An = -2n + 3
Its hard to explain cuz i need paint to explain and my computer is not working properly right now and will be fixed as soon as possible.
c. what is the 35th term of the sequence?
Answer = -2n(35) + 3 = - 67
Yea dun.
NEXT SCRIBE WILL BE MICHELLE..unless u been it already

SCRIBE
Hi its Matthew
what we did last time was that we had a sub for the class
and we got into groups, and had to do the work sheet Pg. 314 # 7 - 12.
In our groups we discus about the questions of how to intercept questions and how it works so we understand it.
ex. y = 2x - 8, and 3x + 4y + 24 = 0
we also had to determine the slope and the y intercept of each line also.
ex. -2x + 3y +10 = 0, 4x -3y - 6 = -6
i hope this is right
next scribe is mark .. if he didn't go yet .
