The question I'm doing is on page 169 (Math Links) question 7 and 9.


So, the answer is B, CD rack

Hello Everyone!

Here's what you need to have in your foldable in section 5.1

All of this in the key ideas section including the question 1 & 2



For the question number 1, what I put is she can be correct, because all you're looking for is the Top, Side and the Front. It isn't necessary to find out the bottom, the other side, and back of the object. You already know what you need to look for to draw the object right?

For question number 2, it isn't correct. Because if you tried to draw that with those Nets, It won't be exactly like the Math Textbook. So I would like change the front image to the top image, and from there, front to side.

Also in class, we did a "Show You Know Question" when I drew it, it looked very different then Mr.Harbeck done. Here is the question we've done.



And here is what I've done, I tried to draw the object standing up. The red square in the middle is where the hole was suppose to be.

Well I hope you enjoy my post!

11. An injured bumblebee sits at a vertex of a
cube with edge length 1 m. The bee moves
along the edges of the cube and comes
back to the original vertex without visiting
any other vertex twice.

a) Draw diagrams to show the
bumblebee’s trip around the cube.

b) What is the length, in metres, of the
longest trip?

8 arrows
x
1 metre per arrow
=
8 m in length

Percents %

HEY EVERYBODY! Here is percent.

PERCENT: A percent is an equivalent fraction out of 100.

Our homework is to find the percent of the following fractions in 3 different ways. (I'll cover 1 and leave the rest to you guys).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5/7
One way to find the percent of this fraction is by first, converting it to a decimal. In order to find the decimal equivalent of a fraction, we multiply the numerator by the denominator.

5 divided by 7 = 0.71

Now that we have the decimal, we have to find the percent, by multiplying the decimal by 100. We multiply by 100 because, remember a percent is an equivalent fraction out of 100. A decimal is an equivalent fraction out of 1, so in order to get from 1-100 we multiply by 100.

0.71 X 100 = 71%

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Another way to find percent is by creating an equivalent fraction out of 100. In order to get from 7-100 we have to multiply by 14.2. And remember, what you do to the top, you do to the bottom.

5 X 14.2 = 71

Now our fraction is 71/100

This means that our percent is 71%

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A third way to figure out percent is by using ratio.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So there is 3 different ways to figure out percent. Have fun with the rest!

In class we learned that:

Discount: What you save.

Sale Price: What you pay.

1)

For this problem I tried to use a ratio table:

First I fould 1% then I used that to find the

GST:1.75

PST:2.10

The total cost of the backpack would be $38.85

$35.00

$1.75

$2.10

= $ 38.85

2)

100%-40%=60%. So I found 60% out of 35. And then I found the GST and the PST, from that.

Sorry if Im wrong, if you see any mistakes or something that's missing please comment.

4. How many hundred grids are needed to show each of the following percents?
a) 101% We need 2 grids because 1 grid is 100% + 1 more grid that's 1%=101%









b) 589%=6 grids A grid is a 100% and we need six of them to cover 589% We need 5 grids that's completely shaded and 1 grid that's 89% shaded.
















c) 1450% 100%=1grid
1000%=10 grids
1400%=14 grids
1450%=15 grids

9. Copy and complete the following table.















15. A forester recorded the following data on tree types.

a) What is the total number of trees recorded? 1814 b) What percent of the total does each tree species represent?
