T-mobile charges $34.99 a month for phone service. They also charge $0.48 per minute for long distance calls. If Joshua's bill was $64.75, how many minutes of long distance calls did she make?

Part A - Write an equation that can be used to solve the problem.

Equation: $64.75 ÷ $0.48= 

Part B - Solve your equation and answer the question in a complete

sentence.

$64.75 ÷ $0.48= 134 

Joshua made 134 long distance calls 

Haiku Poems.

Green leaves in the woods.  

They all fell off of big trees 


Standing tall and proud

The rain damaged it

The petals bend to the earth. 

Now my flower is ruined.   

You're always typing.

Well, let's see you ignore my

I.M that I sent  

Wanna go outside.

Then My brother locked me out. 

Let me back inside!                

 

Sad 

It’s nothing to do

I can see now we are threw

I may wipe my tears 

Aim: How do we evaluate algebraic expressions?

Write each expression another way.

1. 12x 2. 4/y 3. 3xy/2
12*x y÷4 3⋅x⋅y/2
12⋅x y
x(12) 4
12 x X


Explain the difference between variable and a constant.

The different between variable and constant is that, variables are letters that represents a number that can vary in a equation and a constant is a number that can never change.

Aim: How do we compare and analyze sample methods?

I like to survey the whole school about who likes to be on aim in class.
*Random Sample: Ask 50 random people that I see in school.
*Convenience Sample: Ask 20 people that are on my school team.
*Biased Sample: Ask the students that you see on aim in school.

Display Data

Aim: How do we use spreadsheets to create graphs.

Yesterday in class I learned something new and it was fun. I learned how to use spreadsheets to display data into different kinds of graphs such as pie charts and bar graphs. First, I wrote down all the information that I needed. Then, I picked Out which graphs I wanted to compare. Also, When I found it I put all my information in both of the graphs and added my title. Finally, I compared both of the graphs together and from the information that I was using it was easier to understand it on a bar graph because in the pie chart it don't show that much information and in the bar graph they show a lot of information like how many people spent on each activity. I did the graphs on a spreadsheet on our computers and for me it was way better to understand.

Think and Discuss Question:

1. The bar graph is better to understand then the pie chart because

in the pie chart it don't show that much information and in the

bar graphs they show a lot of information like they show how many of

them spent on each activity.
