Hello. I'm in Algebra II and I'm having trouble with this "math project." The idea was to make a piece of "art" and you have to write the equation for each line. I made a rocket because it looked like something and has all the functions we had to us...

OK. I dont understand how to find the prime number to eliminate. I guess what I am looking for is for how you get 125/72 out of 500/288

anthropology
I suppose the discrimination against many people who look like Arabs/Middle Easterners and Muslims in general after 9/11 and the events after it could be considered a global apartheid. Think of any recent racial discrimination common to most of the world.

math
Sorry, I meant square root of 4x to the fourth, unless you mean (four times four) to the fourth, which would be (4*4)^4 and would be solved differently. 4x^4 = 4x * 4x * 4x * 4x, then find the square root.

math
Square root of four to the fourth? This'd be written as sqrt(4^4). 4^4 = 4 * 4 * 4 * 4. Find the product of that, then the square root of the product.

Oh! Thanks. XD I've been rearranging polynomials all day and I swear it's hardwired now. "Parentheses; distribute, resistance is futile"

math
Actually, I come to h = 160 here (?) so I think I've done something wrong. Are you not supposed to distribute when multiplication is used as in (32 * h)? Sorry, you might want to wait for someone else to explain.

math
You should distribute first: 96 = .5(32) + .5h 96 = 16 + .5h Do you know what to do from here?

math
That's better. The area of the rectangle is (12 * 8) or 96 sq. in. 96 = .5(32 * h) Solve for h; post if you need more help.

math
Is there enough information to solve this? I can't figure out how it might be set up (even plugging in answers to see if they fit) without more information, such as some about the rectangle, or the area of the triangle. Maybe someone else knows.

2(24 * 9) + 2(18 * 9) = ? (Four walls -- two 24 by 9 and two 18 by 9, equal the amount of wallpaper needed). Don't forget to convert the result from feet to yards.

biology
Plankton, I think, as most other marine organisms depend [at least indirectly] on plankton, as they feed on them or feed on those who feed on them, and the absence of the base of a marine food chain would cause more problems overall than that of a group of predators.

Math
Compute is to calculate or evaluate.

math
Fractions are converted to decimals by dividing a by b in a/b. For example, 3/4 = .75. Some decimals and fractions are easy to remember -- such as 1/2 = .5, but most you will have to calculate on your own.

It'd be "a la una y media" just as in "es la una..." unless I've forgotten and am doing it wrong. I haven't had to tell time in Spanish outside of classes, funnily enough, so I could have made a mistake.

spanish
To indicate the time at which something happens, use "a la..." or "a las..." as in: La clase comenza a la una y media y termina a las dos y catorce -- The class begins at 1:30 and ends at 2:14.

I see, thanks. It looks like it might also be possible to use 'toward' (if I'm right in thinking the definition 'in regard to' is in use here) and it does Sound Right but I never see that. I liked English more when I didn't think about it.

What's funny is that I don't know /why/. I always see 'with' used here, but have no clue why it is that way. Does anyone know if it has a reason for not being 'for' or 'of' instead, or is it just arbitrary?
