Picnic Table Question

For the picnic table question we had to find the cheapest way to purchase lumber for a picnic table using the given dimensions.
I first took the top view to find out that I needed 4 7ft 2X12 boards. That works to 2-14ft-2X12's.
I then took the side view to find out how many pieces of what lengths I needed, and came up with 6 3ft lengths, and 2 5.5 ft lengths of 2X4 boards. To find out what lengths of boards I would need to purchase, I made a diagram to find out lengths of boards I would need, and came up with 1 16ft board to accommodate 5 ft lengths, and a 14ft board to accommodate both 5.5 ft lengths, and the last 3 ft length.
I figured out the cost with the cost of miscellaneous hardware and came up with the total price.
The second part of the question was to find out the cheapest way to build 2 picnic tables.
First I got 4-14ft-2X12's for the table top. I then got 2-14ft-2X4's so each one can get 2-5.5ft pieces for the seat supports and 1-3ft piece for the table supports. That leaves 10-3ft pieces still needed, which works nicely to 2-16ft boards with 1 ft waste on each. I then multiplied the boards by the cost of each, and added the miscellaneous cost onto it as well.
That was the question for the portfolio!

Driveway Question-Portfolio

At the start of class we had conversations about starting a Facebook group for our math class, and then watched a video on Media Literacy. The video showed us how far technology has come in the last 6 years(with Facebook and My Space), and how in 25 years something like a computer could fit in a blood cell, thats how small it could be.
When we finished the video Mr.Max showed us a few steps to finish the Driveway question from our Portfolios. -First we had to figure out the area of the driveway.
-Then for each method we figured out how much would have to be dug down for the excavation.
-Once you have done that, you find out the cost of each type of material for each method needed in cubic yards(1 yard cubed is equal to 27 feet cubed). To find the cost I multiplied the depth by the area to find feet cubed, then divided the answer by 27 to get yards cubed. After I did that I multipled it by the price per cubic yard.
-When you have calculated the cost of materials and the cost for excavation for each method, you find the total cost it would be without taxes or labour costs.
The rest of the question was due for the next day

Portfolio Continuation

First thing this morning we got our Matrices tests back. I did really good on the test, no troubles.
After we got our tests back we were to do a question in the portfolio's on page 6. We had to look at 2 methods of how to do a driveway and find the total cost of either driveway. The question is due for tomorrow.

Spot Check

In yesterdays class I was given the spot check work booklet to finish when I have the chance from missing Monday & Tuesday. There was also a formula sheet for Sequences/Series & Personal Finance that was assigned.
We got a Design & Measurement Portfolio booklet. We started to go over the questions, we were to do the 1st part of question 2 on page 4 of 4. The question was to find out how many ceiling tiles you need to complete the ceiling of a room, with the square tiles laid in the center of the room.
To do the question I divided the dimensions of the ceiling into 4 quarters. I then figured out how many full tiles I would need, and how many partial tiles(for each tile that was less than half, I used 1 full tile cut into 2 partial tiles) for each quarter. Then, I multiplied that number by 4quarters to find out how many complete tiles I would need for the full ceiling. Once I got the total number of tiles I would need, I figured out how many packages I would need, and from that I got the price of the total price ceiling tiles.

Surprise Test

Today we had a "test". We went over some provincial math exam questions.
One of the questions showed us that doing the questions through the calculator can give different answers than Excel. Through the calculator it gives you a more accurate number because you can change how many times the amount is compounded semi-annually which changes your answer. So when there is a question with different compounding it is easier to do it on the calculator.
We also did a question that needed the Statement of Net Worth. There are templates on the coursework drive with this statement so we don't have to make our own:)

Personal Finance-Tricks

Tricks:
There are some tricks you can use on the calculator to help you do a certain part in a question. You can find these in the applications part of the calculator. They have a weird E looking symbol in front of the first 3 letters of the function.
Sum of Interest-Gives you the total interest paid between 2 points in time
Sum of Principal-Gives you the total amount paid on the principal between 2 points in time
Balance-Gives you the balance at one point in time.

Templates-Personal Finance

Today we went over the 3 templates:

1)Net Worth Statement
NW=Own-Owe or NW=Total Assets-Total Liabilities
2)Debt Equity Ratio
D.E.Ratio=(Total liabilities-Mortgage on your home) x 100
Net Worth
*Most desirable ratio is 0%*

3)Gross Debt Service Ratio
GDSR=(Monthly Rent/Mortgage+Monthly Taxes+Monthly Heat) x 100
Gross Household Monthly Salary
*Usually associated with housing costs and not to exceed 32%*

Homework Check Day

When Mr.Max went to do the homework check yesterday most of the class hadn't done the 2 questions that were assigned over the long weekend. So we were given time to try and finish the questions, and then we went over question 5 together as a class.
For Fridays class we continued to review the personal finance unit. We went over question 8 kind of as a class. We were given questions 3&5 to do for Monday morning. Mr.Max said that he doesn't want to see nothing when we show up on Monday.

Personal Finance-Excel

Today the day started off with a little bit of snow on people's cars in town. Winter has arrived..
Mr.Max showed us how to make an excel spreadsheet that gives us the same information that we figured out with the TVM method yesterday, but on excel you can see the progress of the loan(how much still owing by when, etc.)

Personal Finance unit.

Class started off with Mental Math. When that was done we had to calculate our average out of 8 quizzes and hand it in to get marked.
When we finished that, we started our next unit:
Personal Finance
Tools that we will be using for this unit are the:
TVM solver(calculators)
Excel
*Web Applets from Canada only*
Today we started with the TVM solver. This allows us to put info from taking out a loan etc in the calculator and from that we can calculate monthly payments, costs of borrowing, etc. We went over an example question of buying a car, and we figured out what the monthly payments would be for the car with a 5 year loan.
From there we were given some practice questions

Sequences

Today we started off with Mental Math, then we were told we have to complete 2 questions from the Sequences Review Questions and hand them in for a test mark. I wasn't here for the last few days from getting my wisdom teeth removed, but I have to get it done as soon as possible to hand in.
