What number does pi represent?
3.14
Billy Joe Bob shows all of their work on a question.
Billy Joe Bob gets the question wrong. Do they still get some marks?
Yes.
-35 + (-40) =
-70
Bob watches tv for 1 hour on Tuesday, three hours on Wednesday, 5 hours on Thursday and 8 hours on Friday. Does his T.V watching habits represent a linear relationship?
no
Solve for X
x = 5 + 3. What is the value of x?
8
What is the definition of circumference?
The perimeter of a circle.
Billy Joe flips a coin 10 times. Each time they landed on heads!
Is Billy Joe more likely to flip heads or tails on the 11th flip?
It is a 50% chance of flipping heads or tails.
-20 x 5 + (-30) =
-130
A straight line on a graph represents a linear relation?
A) no, it would not be linear.
B) Yes, it is linear
C) Not if the line is going down.
B)
Solve for S
8 + s - 3 = 5
Subtract 8 from both sides.
s - 3 = (-3)
Then, add 3 to both sides.
S = 0
What is the definition of area?
The space a 2-d object holds.
If point A starts at (-3, 8) and transforms 2 spaces right and 3 spaces down, what would its new coordinates be?
A' would be (-1, 5).
40 - (-10) x 3 =
70
Billy is a plumber. He makes 25$ an hour and an additional 40$ when he gets called to a house. What expression is correct?
A) M = 25h + 40
B) M = 65h
C) M = 40h + 25
A) M = 25h + 40
Solve for p
7 + p - 4 = 12
Subtract 7 from both sides.
You are left with p - 4 = 5.
Then, add 4 to both sides.
You are left with p = 9
What is the major difference between radius and diameter?
Diameter goes all the way to the other side of the circle. Radius stops in the center. Diameter is twice the distance of the radius.
What rule do we use to help us subtract integers?
Keep Change Change.
-85 x (-1) + 3 - (-10) x 2 =
112
Bob owns a bakery. Bob sells 5 muffins an hour, and 10 cupcakes when the store opens.
What would the linear expression be for this equation?
S = 5h + 10
Solve for x
2x + 7 = 25
x = 8
Subtract 7 on both sides of the equation.
You are left with 2x = 16.
Divide both sides by 2.
You are left with x = 8.
How would you find the radius of a circle if you are only given the circumference?
Divide the circumference by 3.14.
What is volume?
The space inside a 3d object.
