Y-intercept represents the maximum number of spaces he can rent, renting each space for $0. X-intercept represents the maximum amount he can charge per space, renting 0 spaces. Also a minor correction to slope: The more he charges, the fewer spaces he will rent.

But if the question wanted me to find the moles of O, how would it be phrased? Thanks

Divide 20/35 and 24/36, and pick the answer equal to 2/3.

2:3, "two to three", and 2/3 all mean the same thing

I wonder who benefits from the adverts, then...

Who is "we"?

Are you supposed to fill in the diagram? It's just a matter of organizing and using every bit of information the problem gives you. Try to work backwards from this answer to learn how to do it. none-22, tng-73, ds9-17, voy-11, tng/voy-31, tng/ds9-23, ds9/voy-14, tng/ds9/voy-9

Thanks. I read ahead a few pages and found what I wanted to know.

I've always hated problems like that. You can use this site, just set the maximum number of words to one. wordsmith dot org/anagram/advanced dot html

Could you rephrase the question?

2/3 * 12 = 24/3 = 8

That sounds pretty advanced for an elementary class. One way you could start to solve this is to use a few different values for n and see what you get. Using n=1,2,3 we get p=7,13,19. Do that for a bunch of numbers (a spreadsheet program like Excel or Openoffice Calc will help with this) and see how many are prime.

Got it, thanks! By the way, when you're talking/writing, how do you decide where to put the "se" since it doesn't matter where it goes?

It helps to draw a picture. You can ignore the length of the fence, add 2 to 8 to get the length of the one leg of the triangle (the other is 13), and use the formula a^2 + b^2 = c^2

The book could be wrong. The wording is a little confusing too.

The Wikipedia article "Cell cycle" has an excellent diagram in the Phases section.

The decaf coffee contains 3 units of caffeine per cup (100 minus 97). The regular coffee contains 100 units of caffeine per cup. Two cups of regular coffee contains 200 units, so you would have to drink 200/3 = 66.666 cups of decaf. 66.666*8 = 533.333 ounces

Find the least common denominator by multiplying the prime factors, 7 and 2, and x to get 14x. Multiply each fraction by 7x, 2, and 14 respectively so that they share the denominator 14x. Add the numerators to get (7x+74)/14x. Simplify 7x/14x to 1/2 and 74/14x to 37/7x to get (1/2) + (37/7x)

Hydrogen peroxide is H2O2. First, convert the given amount (1kg O2) into moles. One mole of O2 is 2x16g = 32g. 1kg = 1000g. 1000/32 = 31.25, so we need 31.25 moles of O2. One mole of H2O2 contains one mole of O2, so we need 31.25 moles of H2O2 to produce 31.25 moles of O2. The problem asks for the "amount" of H2O2, which could be given in moles, but since O2 is given in kg I would convert the answer into kg. One mole of H2O2 is (2x1g)+(2x16g) = 34g, so 31.25 moles is 1062.5g or 1.0625kg.

It helps to start with a simpler problem. Try solving it manually, by drawing out each possible seating arrangement, with three members instead of six. The problem specifies a circular table, so we can probably assume that there is a difference between circular and linear arrangements. What I did is write out 123, 132, 213, 231, 312, 321, which are all the possible linear arrangements. Now to make them into circular arrangements, where there is no beginning and end, 123 becomes ...12312312... which also contains 231 and 312. The other arrangement turns out to be ...13213213... (I'm assuming it doesn't matter which chair each person sits in, only their positions relative to each other.) Three factorial = 3! = 3x2x1 = 6 linear arrangements and 2! = 2 circular arrangements. This pattern becomes clear if you do the problem again with four people. The answer to the original problem is 5! = 120

a+(a+1)+(a+2)=(a+2)x2 combine like terms 3a+3=2a+4 subtract 2a from both sides a+3=4 subtract 3 from both sides a=1 the integers are 1,2,3

Before you start multiplying, you need to make sure everything is in the same units. For length, you can use either cm or m. I'll pick meters. That means we have to convert 100cm to m. There are 100 cm in a m, so 100cm = 1m. Meters x meters = square meters (m^2), and 1m x 1m = 1m^2.

It helps a lot to draw a picture. Although the problem does not specify how the points are arranged, I assume they are in a line. Your picture should be a line with points a, b, and c on the line. Now write 3x above the ab segment and 5x above the bc segment. Draw one of those fancy brackets { encompassing the entire line and write 8 on the tip. Now that you have your picture, you can see that ab + bc = ac, which means 3x + 5x = 8. Does that help?

Find the molar mass of N2H2. Now find the number of moles that are in 5.0 x 10^14g of N2H2. With me so far?

This looks more like late middle school math to me. Anyway, the equation is f(4) = 8(4^2) = 8(16) = 128. Notice I replaced x with 4 to set up the equation, so that it reads "f of 4 (the force needed to stretch 4 centimeters) equals 8 times 4 to the power of two"

Oh, sorry, I thought I got to your question earlier than I did. I guess this site doesn't work too well for real time discussions...

((4x^3)(y^-2))/((2x^-1)(y^4) The way you typed your equation leaves some ambiguity; I'm assuming this is it. First move the variables with negative exponents to opposite sides of the fraction bar, and make those exponents positive. Then add the exponents and multiply the constants for each side. The answer is (8x^4)/(y^6).

Adverbs are words that modify adjectives, verbs, or other adverbs. Many end in -ly. Check out the Wikipedia article for examples.

The formula for slope is change in y/change in x. F(x) is the same as y in this case. Change in y = 2--2 = 4. Change in x = -3-5 = -8. 4/-8 = -1/2

Thanks. I already know all of what you said, except for that last sentence (Wouldn't that only apply in certain keys? C seems much easier for 3rds, 4ths, and 5ths than C#). I just want to know how to generate that list in a spreadsheet.

The lesson is Lesson 5 Polygons and Angles for Unit 1. This thread confused me so I'm going to give the right answers... 1.) B 2.) C 3.) A 4.) B 5.) A 6.) C 7.) D 8.) C 9.) B 10.) D 11.) C 2/3/2017

It’s C

I just tested it out myself and got it correct! It is in fact C

It resulted in addiction and conflict.. I just tested it out and it is infact correct! ❤️

Would it be 367

My bad

I believe it's D

Also a 6th grader doing the Unit 3 Lesson 9 one. Use JoeHoe’s answers. For the last few, I used BirdCaptain10’s answers but changed up the wording and how I put it (Idk if they’re right tho, they haven’t been graded yet)

Thank you so much:)
