Think of a regular hexagon. All the angles are 120°. Now, think of pressing down on the top, keeping the top and bottom sides parallel. The two side angles will decrease, and the other four angles will increase. Stop when the side angles have become acute...

No. Tin and antimony are elements. Therefore their formulas (Tin- Sn | Antimony - Sb) are already in the simplest proportion formula wise. So that's the Empirical formula. That's where you start and answers do you need the Empirical formula

Certain crops take certain amounts of water to grow. So in wet lands, Rice and tropical fruits can be grown since a lot of water is required for it to grow. In dryer lands, Irrigation can be used to moisten the lands to allow for more water to come in, or...

Repeating the 4 digit number is the same as multiplying by 10001, which factors into 73*137 (both prime). The only way 10001n does not have some other prime factor is if n also has only prime factors of of 73 and/or 137. Since 73*137 is 5 digit number, an...

Ahh that helps too. Alright Economic: The cotton gin allowed for more cotton to be produced. This doubled production as decades progressed in the 1800's Social: trade increased both in local areas and exports of cotton based products (clothing, etc.) incr...

1. x/15 = 3/5 Here, all you do is multiply each side by 15. The end result is x = 9. 2. More specifics here are needed. The x could go on either side of the proportion and the x could have a higher value? is there? 3. 1:3 Ratio (1 Trombone for 3 Violas. a...

Amethyst, it says you have to be patient for your help to come. People like me are working hard to try to help solve people's questions. Let's solve yours, even though it might be too late and you may not see this. Mark's appointment was 35 after Tyson's...

Lilly, I don't know where you get the 20 from, maybe as a generalization? Anyways, your answer is right, but you forgot the actual percent 33.33 (repeating)% is closest to 1/3. If you take 33.33 and multiply that by 3 (3 thirds make a whole), you get 99.9...

Thanks Jai for correcting me. I obviously read that too fast. Yes. All seems correct.

Self-importance is an exaggerated sense of ones own value/importance. This is kind of an opinion based question, but C and D both seem good. Personally I'd go with D since it talks about how much an heirloom is worth, but that's me. C also seems good.

You are correct. Since you have to find the probabilities of picking both rubber band types from the box, you need the total number of rubber bands. Which you added correct. From there just get the answers by putting the appropriate numbers (for each colo...

Yes. The answer is most likely B here. A is too obvious and would show greater smile, not a faint one. C might be a correct answer, but I doubt it as it might not be a GOOD important decision. D is most likely unlikely as the facial expressions would be o...

Also I base this off of what has been shown here. I suggest you do what Reed says and look at the previous lines as well for insight.

A- Correct - Fans change electrical energy into kinetic energy (motion energy is an acceptable term too) B- Correct- If a material isn't a good conductor, it can be used as an insulator.

Oh, is it the one in asterisks (C)? If so, I don't think that is right. The sizes of the boxes aren't given, only the masses. Mass and size are two different things.

Because we are talking about gravitational pull, size does not matter. Generally, the more mass something has, the stronger a gravitational pull it has on it's surroundings. Think of the Sun and Earth. The Earth orbits around the sun because the Earth has...

Yes. The common ratio is 1/3 the previous term.

Yes, this is correct. The common ratio is -2 times the precious term.

Look at where the variables are placed and what they mean. Then look back at the question and look at the words. Try to see if you can find the error from there.

Look at the total number of marbles from the one group, and look at the percentage that is estimated for the collection. You should be able to figure it out from there.

A is not the correct answer here unfortunately. Also, are the "Arithmetic" or "Geometric" parts of the answers missing? They were there for the previous questions I helped you with.

Alright, yeah. That's kind of confusing. Still, A is not the correct answer. A's next 3 terms assume this is an arithmetic sequence, as the common difference is +10. (60-10=50 & 50-10=40). That is not the correct sequence based on the first 4 terms of 3,...
10 years ago
Yes, C is the correct answer. The common difference here is +9, resulting in those next 3 terms, making the entire sequence true.

Where are the radicals here? I do not see them? I know it's hard to type them, but could you please specify, maybe with parenthesis?

To be honest, this question is very simple. You can look at the number after the decimal in (1.04) to find the percentage. just multiply the .04 by 100 to find the percentage. As for the population in 1990, since the year is 1990, t would be equal to 0, (...

A number was not specified as the starting amount, so I am assuming the starting number will be 1. You would use a formula like: y=a(1+r)^x a = the initial amount before the growth begins r = growth rate x = the number of intervals y= end result r=1 since...

There aren't any radicals in this problem then. This problem alone though is a pain itself. Firstly, since both fractions are negative on each side, you can eliminate them and reorder so you have (2/3+27 / 1/3+27) Then, I would suggest multiplying both si...

I would reorder the entire fraction first, to make working with the fractions easier -2/3+27 ________ -1/3+27 Then we should multiply each side of the fraction by the denominator's conjugate. -2/3+27 (1/3+27) ________________ -1/3+27 (1/3+27) -2/3+27 (1/3...

Maxine, you mentioned earlier that there were exponents in this problem. I can't see them at all because that's the computer and how you are typing. I acknowledge this question is here, and I'd love to help, but unfortunately, you need to make the exponen...

27^-2/3 ____________ 27 ^-1/3 First with your given problem, you need to convert each negative exponent into a fraction. We will start with the denominator. 27 ^ -1/3 turns into: 1/(cube root of 27) 1/(cube root of 27) = 3 Your problem now currently looks...

You could technically use either make or makes. Even though make makes the most grammatical sense, in everyday speak, I often would see people use "Makes" even when referring to a singular noun first, For example: "The fact that Bob did his paper turned h...
