I am a bit confused at what you mean n=-40.0891...

How is -4949/101=-40.0891? 

Maybe check your math...

P.S. Next time, maybe be a little nicer instead of saying "This screws up your answer"

:)

Correct!

:)

Hmmm, try counting again.

Check your answer here: the number of spaces between 2-P is 5, and the number of spaces between 2-3 is 8. So, the fraction is 5/8. Add that to 2, and you have 2 5/8 (2 and 5/8, not 25/8). What is that as a decimal?

To solve this, we need to first create an equation.

The equation will be n+(n+1)+(n+2)...+(n+99)+(n+100)=101

Combining like terms, we get 101n+5050=101

Isolate the n:

101n=-4949

n=-49

So, the smallest number is -49, and the largest is 51.

:)

hmmm try again. what did you get for your fraction?

This one is not too hard to solve. Here are the steps:
1) Find out how many spaces between the lines there are TOTAL (between 2 and 3) (that will be your denominator)

2) Find out how many spaces between the lines there are FROM 2-P (that will be your numerator)

3) Now, you have your fraction!

4) Add your fraction (in decimal form) to 2

There!

Since this is a 30-60-90 triangle, we can use the 1:sqrt(3):2 ratio for the sides. 

Base=9

Height=9sqrt(3)

Here, we can start fiding the answer. So, bh/2 is 81sqrt(3)/2~70.1

So, the answer is 70.1

Hi EP! I tried doing this problem, and I got a different answer from you...but nice job! (you might actually be the right one!)

Here is how I did it:

Since there are a total of 8 people, we start out by multiplying by 8.

Next, whether the person is a boy or a girl, we need to choose someone from the other gender. That gives us 4.

Now, we multiply by what is remaining, which is 6.

8*4*6 = 192

I'm not to good with these questions either (my brain just keeps on thinking about "what ifs"), so my answer might not be correct.

:)

Thank you! I was just confused on what you meant by adding points. Now I see. I have learned lots from your answer :)

P.S. Do not be ashamed of yourself! Everybody makes mistakes! All you have to do is learn from them, and you will live a happy life 

:)

Oh! That makes more sense!

Thanks EP!
