Thank you for helping me by explaining to tell me what i had to do to go figure out the answer instead of just giving it because some people on here in the past thought i used people to get me answers when i can't get certain things you know and i be asking for a little assistance.

Correct!

:)

5/8 + 2

A. 2.625

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?

6/4 

As i counted from the spaces between 2 and 3 also from 2-P

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?

Is it D ?

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

Hi buddy, 1277 is the right answer.

This question yet again!

See https://web2.0calc.com/questions/i-m-really-stumped-polynomials

At what point does the graph of 3x+4y=15 intersect the graph of x^2+y^2=9? Express any non-integer coordinate as a common fraction.

Given R(-6, 19) and S(15, -5), what are the coordinates of the point on segment RS two-thirds of the distance from R to S?

OB = OC + CB = 68

Radius AK = OB - MB = 50

Area of the semi-circle with center k...  A = (50²pi) / 2

The sum of the coefficients of a polynomial is easily obtained by setting x = 1.

Like so:

So x = 13

Continued on the original.  I will delete this thread later on.

Draw the triangle on a piece of paper.

Use Pythagoras's theorem. to find the length of the hypotenuse.

Now can you do it?  If not tell us what you have found so far.

A lecture hall contains 20 chairs, all lined in a row. What is the number of ways that five chairs can be chosen, so that no two chairs are adjacent?

There will be 4 children each with an empty chair on their right, that is 8 seats taken.   But since they are tied in pairs, it is just 4 positions gone.

The fifth child will sit to the very right of all the others but there may not be an empty chair to his right.  So now there are 9 seats but just 5 positions taken.

There are now 11 seats left that all have their own position.

So there are 16 positions in total and I want to decide where the 11 can go.

 So that is 16C11 = 16C5 = 4368 

so I think there re 4368 arrangements and that is assuming that all the chairs are identical and all the children are identical.

Well it is a line intersecting with a circle so it could be 0,1 or 2 times, but you are already told that there is only one point so the line must be a tangent.

If you want to check I would use the perpendicular distance formula fro a point to a line.  I have done that and the distance is indeed 3.

And three is the radius of the circle so the line is a tangent to the circle (only 1 point of intersection)

You could just solve the 2 simultaneously.  That is the normal way

Or you could say that the equation of the line is 

$3x+4y=15\\ 3x=15-4y\\ x=\frac{15-4y}{3}\\ \text{So a point on the line is } (\frac{15-4y}{3},y)$

use the normal distance formula and put the distance =3   solve for y then solve for x
