Runcel's Growing Post

a) Post your recorded quiz.

b) Using one question from questions 6 or 7 on page 202 of the textbook, explain two ways to multiply a fraction by a whole number. You should use pictures to help explain!


The first way i did is to show a picture



So the answer is
21/10


c) Using one question from questions 4 or 5 on page 208 of the textbook, explain how to divide a fraction by a whole number. You should use pictures.





SO THE ANSWER IS 1/8

d) Pick one word problem from questions 6-12 on page 208 of the textbook.

The second part of our fraction growing post is to show our understanding of multiplying fractions.

Use our test to choose 3 questions.

1:Fraction*Fraction

2:Fraction * Mixed number

3:Mixed number* Mixed number

Rectangular Prism

• Draw a Rectangular Prism
• Draw its net.
• List all measurements on the drawing and on the net.
• What formulas do you use to calculate surface area?
• Calculate our the surface are of your rectangular prism.

Triangular Prism

• Draw a Triangular Prism
• Draw its net.
• List all measurements on the drawing and on the net.
• What formulas do you use to calculate surface area?
• Calculate our the surface are of your triangular prism.

Rectangular prism
L*w=Area
10*5=Area
50*3=Area

TSA=150+63=213CM

Cylinder

• Draw a Cylinder Prism
• Draw its net.
• List all measurements on the drawing and on the net.
• What formulas do you use to calculate surface area?
• Calculate our the surface are of your cylinder prism.

Area=pi*r*r
=3.14*1*1
=3.14


c=Pi*d
=3.14*2*2
=12.56


TSA=3.14*12.56=39.4

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.

3. Determine the length of each hypotenuse









4. What is the length of each hypotenuse?

Give your answer to the nearest tenth of
a centimetre.


A:)

Runcel's scribepost Page 92

Question 4:)


what are the areas of the three square ?


1:) e=30mm


1 and 2 Are the legs And 3 is the hypotenuse


2:) f=40mm


3:) g=50mm


1:) e=30mm
A=900cm2
the Area is 900cm2


2:) f=40mm
A=1600cm2
the area is 1600cm2


3:) g=50mm
A=2500mm2
the area is 2500mm2

Runcel's BOB on Graphing(late)

Three things I know about graphing:)

1:) A graph can be distorted , you can a put a break in the y-axis.

- A break in the y-axis of a graph means the length of the axis has been shortened.

2:) There are many different Type of graphs:)
EX:)
bar graph

line graph

circle graph

pictograph

3:) Every graph has to have labels or titles
