Chapter 5 (Area)

Video

This video just covers the Area of a Trapezoid, but the other videos on the right cover the rest

of the material we learned form this chapter.

Web Site

This site covers all of the things we learned, but the last few things at the bottom of the page

we did not cover, so disregard them.

Venn diagram

Here are four examples of complementary and supplementary angles. You can see here how complementary angles add up to be 90 degrees and supplementary angles add up to be 180 degrees. Use the four examples to solve for the unmarked angles and look at the writing in the red to check your answers.

Finals time approaches

Hey all,

In Friday's class we worked in our small groups on our "final assignment." In my group we are making a problem that uses proportions to find the lengths of sides of shapes - from chapter 7. We are making one big massive problem that will be awesome!

Don't forget: your assignments must be posted on the blog by the end of Monday!!

As finals time approaches, here are some helpful tips:

- if you are behind in any of your classes, get those assignments completed this weekend, once those are done, even if you aren't completely on top of your studying for your finals, you will feel 10 times better.

- If you get those last assignments completed this weekend, or if you are already on top of everything....get studying!! If you get on top of your studying for finals this weekend next week with go by in a giff :). Just keep telling yourself one more week!...go out with a bang.

- tips for studying:

* go through your old tests and quizzes to see what you remember

*review homework and notes from sections you don't remember very well

*do some problems from your tests and homework (make sure you do at least one from every section and topic covered in the chapters).

* if you totally don't know something, go back to the book and your notes and relearn what you forgot

* Also, it is really helpful to make a study guide for all chapters with key notes to remember from the chapter. Or you can make practice tests from homework problems (just make sure you have the answers! so you can check)

- Other things to keep in mind:

1.) DON'T get too stressed, that won't do you any good

2.) get good sleep this coming week, especially the nights before the finals, no matter how much you study, if you don't get enough sleep you will do poorly on your finals

3.) Eat protein enriched foods this week, they will really help you to keep going strong this week.

4.) And finally, take breaks during your studying to exercise, be it running around the block, around your house, doing jumping jacks or just hoping around your room, exercise really helps your brain keep working efficiently.

MATH final help:

1.) come to Panera this sunday at 5pm to study with your fellow classmates

2.) look at the blog to refresh your mind

3.) watch this video to review math concepts:

(ignore the creepy guy with the rat tail and lowcut shirt :P )

Scribe Post, December 4th, Jordan

So today we continued going over Chapter 9, Which is the Volume chapter. We started off with daily quiz #33. which was about the volume of a sphere. Once we were finished with that we went over daily quiz #32. daily quiz #32 was, if you have a sphere with a radius or 6 in a box and its touching all sides what is the volume of the space not taken up by the sphere. So to start this problem you have to find the volume of the box and the volume of the sphere. Drawing a picture first usually helps.

volume of a sphere: Volume of a cube:

V=4/3(pi)r^3. V=b*w*l

V= 4/3(pi)216 V=12*12*12 (radius is 6 & the diameter is 2(r) & 2*6=12 &the diameter=l,b&w)

V=288(pi) V= 1728

V=904.78

Volume of the cube-Volume of the sphere=left over volume

1728 - 904.78 = 823.22 units^3

Then we went over the answers for the homework that our classmates did and check to see if they were correct or if we had messed up in making the problems. After that we talked breifly about Tuesdays test and then were dismissed.

next scribe is Christian.

Scribe Post, December 3, 2009, Noah

Hello Everyone!

Due to my internet being down for the past two days, My scribe post is now being posted.

Today in class we had a very productive day! We are continuing with Chapter 9 and Volume. Remember Chapter 9 Test will be next week, December 8, 2009. It will be our last test before the final. Our final for the class will be cumulative. What is really great is that Jojo told us that everything we have learned, gone over this term, and written on the blog is still online. Having all this material still on the blog, can make it very beneficial when creating a study guide for the final.

Today in class we took Daily Quiz # 32.

"A sphere with a radius equal to 6 in is enclosed in a box. The ball touches all six sides. Find the volume that is unfilled in the box."

Hopefully the next scribe can post the answer to the Daily Quiz 32, in the next post.

We also went over in class Daily Quiz # 31. Anna Daniel did a great job yesterday explaining the answer, which was very useful. Something to remember about the Daily Quizzes for this upcoming week is that they will cover old material. For Example. Daily Quiz #32. was a problem about conversions. We went over conversions in Unit one.

Daily Quiz # 31.

70m/ 1h. ----> ft./1 sec.

Here is the ANSWER to the Daily Quiz #31.

( i know that is written in a weird way, if someone knows how to form real fractions on this blogger, please let me know, and i can fix this. thanks.)

ANSWER:

70m/1 (x) 5,280 ft./1 mi. = 369,600 ft./1 hr.(x) 1 hr./60min. = 369, 600 ft. /60 min = 6160 ft./1 min. (x) 1 min/60 sec. = 6160 ft. /60 sec. = 102.67 ft/sec.

After we went over the Daily Quiz, we all got our Chapter 9 problem homework out and turned it in. Then we were asked to answer someone else question, which was very helpful! It was a great way to challenge ourselves for the test on Tuesday, December 8th.

I hope everyone is feeling confident for the final coming up.

have a wonderful weekend and don't forget to study for the Chapter 9 Test.

Have a great Day,

Noah

This link provides a video demonstration of how to calculate the surface area and volume of a sphere. I hope it is helpful.

I hope this diagram helps with determining the volume of a cone. Enjoy.

Although JoJo was not in class today we had a chance to review our volume worksheets and homework problems. I will list a few formulas that should help you work these to assignments out and help review for the test and the final. Happy Studying and Happy December!

Almost Done!

The Volume of a Stubby:

Vs=1/3(Ab)(Hs)

Volume of Pointy:

Vs=1/3(Ab)(Hp)

Volume of Sphere

Vsp=4/3(pi)(r^3)

Volume of Hemisphere

Vh=2/3(pi)(r^3)
