Is 7/8 rational or irrational?

7/8 becomes 0.875 as a decimal.

The decimal ends so it is rational.

100

Answer: 23/12

Add up all of the fractions by getting like denominators.

If the denominators aren't the same, then we can multiply to get them the same. For example

6(1/2)+4*(2/3)+3(3/4) = (6/12)+(8/12)+(9/12)

Solve the following equation:

3(c+2)=9

Answer: 1

1.) Distribute the 3 through the parentheses:

3(c+2)=9 -> 3c+6=9

2.) Subtract the 6 from both sides:

3c+6=9 -> 3c=3

3.) Divide the three through on both sides to get c by itself

3c=3 -> c=1

c=1

-> Subtract 10 from both sides

-> Divide both sides by 0.50

200

Does the following set of points represent a function?

Answer: No

Reason:

Answer: Yes, Rotate counter-clockwise and dilate bigger.

Reason:

We can change the size and location of the system and while it isn't the same cube it can be similar.

300

Give a rational approximation for √32

Answer:

5^2 < sqrt32 < 6^2

Remember, we are looking for something that when multiplied by itself gets us to 32 because when we take the square root of 32 we will get that number back.

However, we can't get it directly because √32 isn't rational, but we can approximate it by finding the number right above and below it.

Convert the following to a decimal.

1/4

Answer: 0.25

400

Answer: 2ml

Chemical 1 + Chemical 2 + Chemical 3 = Total 3x10^-3 + 1x10^-3 + Y = 6x10^-3

4x10^-3 + Y =6x10^-3

Y = 6x10^-3 - 4x10^=3

Y = 2 x10^-3

Substitute

ml=10^-3

Y=2 ml

Solve the following inequality:

5x+50>100

Answer: x>10

1.) Subtract 50 from both sides

5x+50>100 -> 5x>50

2.) Divide by 5 to get x by itself

5x>50 -> x>10

400

Is this function increasing or decreasing?

Answer: Increasing

The slope is positive, so the function is increasing.

400

Rosie does two experiments and wants to determine if they're dependent or independent.

Determine independence or dependence of the experiments

400

Answer: y=5x-30

Reason:

Each ticket is 5 dollars, but we want the total. To get this, we can multiply 5 by the number of tickets sold, X.

This gives us the total money we are making from tickets, but we also are losing money from rent. We have to subtract 30 to get the total profit.

500

How many solutions does this equation have? 0=8x-8x

Answer: Infinitely Many Solutions

Reason:

8x-8x = 0, Meaning we have 0=0

This means X can be anything we want it to be and not change the outcome.

For Example:

x=4, 84-84=0

x=5, 85-85=0

This pattern continues for any value of x.

500

Is the function linear or non-linear?

Answer: Non-Linear

The function follows a basic parabola form. Parabolas are non-linear.

500

Answer: Yes, Rotate counter-clockwise

Reason:

Changing the position of a cube does not change the cube itself. This includes rotating the cube.

500

Answer: 15/114

Reason:

Before we draw the first bundle, we have 115 total and there are 15 blue bundles.

After we draw the red bundle, we still have 15 blue bundles, but we now only have 114 pencils.

Remember that the probability is

P= (Amount of single item) / (Amount of total)
