Good evening, Monique!
How many calories are listed on the package per serving?
You already know that you consumed 42 "servings" of gummy worms. All you have to do now is multiply 42 by how many calories the package tells you is in one individual serving,...

Good evening, Shayna!
For the first question, to factor the polynomial, we kinda sorta have to use FOIL backwards. You probably already know that when you have two binomials multiplied, you sort it out by multiplying the (F)irst terms, then the (O)uter terms, then the (I)nner terms, then...

Hello there, Jennifer! I hope I can help. If my explanation does not satisfactorily answer your problem, simply let me know, here. Also, if I explain something that you already know, please forgive me.
Let's start with the Slope-Intercept formula, which is y=mx+b. I'm sure you already...

Good afternoon, Breeze!
I assume your question is asking how much one cubic foot costs, correct? If I'm wrong, let me know.
To figure out the cost of one cubic foot, all we have to do is divide. Divide 2700 by 300, and you get a cost of $9.00/cubic foot...

Hello there, Ladonn!
In equations like your example, the constant determines how far 'up' and 'down' the graphed equations starts on the y-axis. For f(x)=x^2+7, when it is graphed, it begins 7 units 'up' the y-axis (because your constant is a positive 7).
We can prove this...

Hey, Kiss!
It's difficult to ascertain exactly what you're asking here. Is "9 less than m" part of an equation you're trying to work out, or part of an inequality, or?
If you're simply asking how to write 9 less than m, that would be m-9. In my experience, word problems...

Good morning, Dalyia!
The first thing you should do is mark these three points on a graph, just so you have a visual of what you're working on. After you've plotted the points, draw a line from C to (-2,0), then a line from (-2,2) to B. Notice you have two right triangles now.
Now,...

Good evening, Kaiden!
Here's a hint: Each previous term is being multiplied by a fraction to get the next term. Can you figure out what each term is being multiplied by to get the next number?
If you can't figure it out, let us know.
Hope...

Hello, Princess!
We are going to set up two equations. One for the mother's and son's ages 5 years ago, and another for their ages in 6 years.
The easiest way to do this is to make the first equation be our baseline of sorts, in other words, rather than saying 5 years ago, we will...

Good afternoon, Bri!
For simple interest, we use this formula: I=Prt. I=interest, P=principal amount, r=rate, t=time.
So, let's plug in the values that we know: 456.70=(5700)r(5). Now, we simply solve for r.
5700 times 5 = 28,500. Now we have 456.70=28500r. Divide...

Hi, Ryan.
Do you have any specific examples which you need help with? Different prisms require different formulas to solve for their areas.
Check out this link: http://www.math.com/tables/geometry/volumes.htm
There, you will find volume formulas...

Anja,
Unfortunately, no one can write a story for you. There is something called "academic dishonesty," which is a big no-no for both tutors and students. If a tutor writes a story for you, it means he/she is doing your work for you, and you are cheating.
You...

Hello, Alexis!
The basic answer is this: Electromagnetic Interference (EMI).
However, I doubt that will be sufficient an answer on your homework. So, check out this article: http://en.wikipedia.org/wiki/Electromagnetic_interference_at_2.4_GHz.
Most...

Hello, Em!
If we consider the total number of points possible, 1100, all we have to do is set up an equation which follows: x/1100=.75
We are saying a total number of points (x) out of the complete total, 1100, is equal to a grade of 75% (lowest B).
So,...

Hello, Amy!
To determine slope, we only need to do the following:
Subtract your second y coordinate from your first y coordinate, then divide by the second x coordinate minus the first x coordinate.
For example:
Use the formula: (y2-y1)/(x2-x1)...

Good morning, Vivi!
Yes, this does have to do with mean. In order to determine which class had the best overall average, you will need to add up every score for each class, then divide those totals by the number of values entered for each class respectively.
Hope...

Hello, Sharon!
We need to set up an algebraic equation.
We know that the length, in feet, of piece(1)+piece(2)=51 feet. Let's call piece(1) P. The other piece, we are told, is 5 less than 3 times that other piece (which we called P); thus, we can express piece(2) as 3P-5.
This...

Hello, L!
I see a few more problems with the paragraph.
-Goldfinch should be capitalized in the first sentence.
-'black and white' would be better written as black-and-white.
-through out should be throughout. (Second sentence)
-In the sentence starting with, "They...

Hello, Jane!
I'm not positive I fully understand the question, but here's what I'm thinking. Let me know if I've misunderstood.
First, add the numbers of each groups' members to find the total number of members. 4+5+6+8+2=25.
To find the percentage of each...

Hi, Leah!
x^2+7x-2 cannot be factored. The constant (c), which is 2, has only one pair of factors: 2 and 1. No matter if either/both is positive or negative, 2 and 1 cannot be added or subtracted to make 7.
This quadratic cannot be reduced...
