#6 A rectangle has an area of 64m square.

a) Determine the prime factorization of 64

b) Is 64 perfect explain?

Yes, because if you use the basket you get 2 sets of 2 per basket.

c) Draw a square with that area and label its side length.

#11 what is the square of each ot

her?

a) 9- the area of the square is 81

A= lw

A= 9x9

A=81 square

b) 11-area of the square is 121

A=11x11A=lw

A=121 square

#12 determine the square for each number?

a) 3- the area

A=lw

A=3x3

A=9 square

b) 18- the area

A=lw

A=18x18

A=164 square

15. Evaluate

c)root 625

25- the answer

25x25=625

#16. Determine the value?

c) root 1600

40

40x40=1600

#19. The gym teacher told

to run twice around the prerimeter

of the school gym. The area

of the square field is 28 900 m square. What is the distance they ran?

1156m

28 900x4=1156m

#22. The world's largest city squ

are is Tiananmen Square in Beijing, China. It has an area of 396 900m 2.

a) what are the dimen

sion of the square?

630m by 630m

b) If the the square had dimension of 629m by 629, what would be the area?

A=lw

A=629x629

A=395 641m

c) If the square had an area

less than 394 000m2 and then greater than 386 ooom2 what are all the possible whole dimensions that it

could have?

622m by 622, 623m by

623, 624m by 624, 625m by 625, 626m by 626, 627m by 627

Part two

#1. a2 + b2 = c2

This is saying that the two small legs a and b

equals to c the hypothnuse the longest leg of the triangle.

#2. Solve the the problem

to find the missing side length do this steps:

1. use formula (a2 + b2 = c2)

2. change letters to numbers

3. square the number (ex. 32 - 3x3)

4. Add the squared numbers

5. find the square root of the total

#3. Is it a right triangle

to fin if its not a right triangle do this steps:

1. use formula

2. change letters to numbers

3. square the numbers

4. add the squared numbers

5. ad it again to make sure it correct

Answer NO

#5. This is question five when you convert fractions to decimals and percents.

a) 51\30

1.7 (51\30= 1.7)

170% (1.7 x 100= 170)

b) 21\200

0.105 (21\200= 0.105)

10.5% (0.105 x 100= 10.5)

c) 3\500

0.006 (3\500= 0.006)

0.6% (0.006 x 100= 0.6%)

#9.This the question when you convert

percentage to fractions and decimals.

a) 5 9\10 or 5.9%

0.059 (5.9\100= 0.059)

59| 1000 (0.059|1000= 59|1000)

b)550%

5.5 (550\100= 5.5)

5.5|10 (5.5|10)

c)0.8%

0.008 (0.8\100= 0.008)

8|1000 (0.008|1000= 8|1000)

#15 This question is when you put the percents in the grid in ascending order.

Numbers: 145%, 5\8%, 1.32%, 0.65%, 33.5%, 6.6%.

(ascending: 5\8 0r 0.625%, 0.65%, 1.32, 6.6%, 145%)

Jairus Graphing post

#1.
- bar graph

advantage- best for comparing different data across categories

disadvantage- can be easily misinterpreted

-double bar graph

advantage- best for comparing two sets of data across categories

disadvantage- can be easily misinterpreted

-line graph

advantage- best for showing changes in data over time

disadvantage- can be easily misi

nterpreted

-circle graph

advantage- best for comparing the whole using percent

disadvantage- is that you must make the sum into 100 and change the other categories to a proper percentage

-pictograph

advantage- best for comparing data that can be easily counted and represented using symbol

disadvantage- it does not show the rate of change in height

#2.

a) Distorting the scale -breaking the y-axis makes bad intervals

b) Distorting the visual -changing the size of the picture

c) Distorting the size of the bar -the area of the bar gets distorted

#2.a) Line graph -it shows data over time

#2.b) yes, the chart shows how much are sold in 4 weeks

#3.

a) the pictograph because it shows the viewer how much sold

b)

Jairus pay it forward

Part #1. "Pay it forward" is when you do an act of kindness and get nothing back in return and keeps going to person to person.

Part #2.
a) my act of kindness is giving candy with a letter saying "pay it forward" and also explaning what we are doing and what is pay it forward.

b) I chose this activity because I don't have to talk to people and it sounded fun.

c) I help people in the sargent park community.

d) I bought candy and took pictures with my partner Paulo.

e) I did it on Tuesday afternoon.







Part #3.

a) are act of kindness went great.

b) we put the envelops and candy in the mailbox and kept doing it until we finshed all.

c) at first I was nervous, then I started having fun.

d) I don't know

e) yes

f) I don't know

Part #4.

a) I think "pay it forward" is a good idea because it's like the first step helping people in the world, by the small act of kindness to big acts they will help you don't know if they need help just do it with nothing in return.

b) I think it made a diffrence because maybe the people we gave it to might needed a " keep going" kind of thing.

Jairus's Proportion post

Task #1

proportion- an equation which states that two ratios (fraction) are equal

Ratio- a relationship between two similar numbers

Rate- compares two quantities measured in diffrent units



Task #2

#1. 5 hours to travel 360 miles is about 1 hour\72 miles

#2. as a playground worker, if I increase amount of apple juice I am serving at the playground from 25ml to 100ml, how much should I increase the orange juice to, to keep the same quantities in the same proportion. The orange juice is 50ml to start.
