Nina mixed 16 ounces of olive oil with vinegar to make salad dressing. How many cups of oil did Nina use? (1 cup = 8 ounces) A. 128 cups B. 8 cups C. 2 cups D. 1 cup

Nina used 2 cups. The correct answer is B. Use this formula;
lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.

y = x(8)
Replace y with 16.
16 = x(8)
Divide by 8.
2 = x
Thus, 2 cups.

Over the last 12 month, Petco has lost a total of $1824.00 due to shoplifting. Write and solve an equation that shows how much money Petco lost each month. ( Since they have lost the money, remember that you need to use negative integers to represent the situation correctly.)

Take y=mx+b  
let x=years and 
y=lost money

then divide 1824 by 12 = 152
and since it is a loss make it into -152
and insert it for m as the constant rate of loss per month
your answer should be y=-152x.
if the store has a starting amount of money plug that into b.

Find the area of the shaded portion of the diagram (use 3.14 for p).A)220.16 square yardsB)6.88 square yardsC)55.04 square yardsD)13.76 square yards

Get the area of the circle. Use this formula: 
Area =  \pi * radius^2

We know the radius is 4 yards.

Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is
Area = side^2

Area = 8^2
Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So, 
D) 13.76 square yards is the answer to this question.

A shelf holds 3 novels, 2 biographies, and 1 history book. Two students in turns choose a book at random. What is the probability of that the students choose each of the following? 1. both novels _____ 2.both biographies _______ 3. a history, then a novel _____ 4. both history books ______

I'll do the first one:
Both novels.

Student 1 picks a novel. There are 3 novels out of 6 books total.

Now there are 5 books left.

Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.

To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.

 \frac{3 Novels}{6 Books} x  \frac{2 Novels}{5 Books} =   \frac{6}{30} =  \frac{1}{5}

So the probability is 1/5. Or 20%

At a rugby tournament, each player on the top two teams receive medals. If 66 medals are purchased for the tournament, and each team has the same number of players, write an equation and then solve for the total number of medals needed for each team.

I'm not sure if this is what you're looking for, it's a pretty simple equation. What math are you in? This is how I would do it.
66=2x
Divide each side by 2
66/2=2x/2
33=x    
 (So each team would need 33 medals so that every player would get one)

Compute and compare the side lengths of the two figures. Does this support an argument claiming that they are congruent? What else must be true to say two polygons are congruent?

The side lengths of the two figures can be calculated with the distance formula:

 √ (x1 - x2)² + (y1 - y2)²        

AB = √13  

BC = √13      

CD = √13    

DA = √13  

A'B' = √13      

B'C' = √13      

C'D' = √13      

D'A' = √13

They are all the same lengths. This supports an argument claiming that they are congruent because if the sides are congruent, then the two polygons are congruent.

Something else that must be true to say that two polygons are congruent is that the angles have equal measures.

Hope this helps! :)
