Need some help with school? You’ve come to the right place!
Welcome to the Training Hollow, where you can get help from or help others with their academics! If you can’t quite understand something you learned in school or you’re stuck on a particular question, ask away for help on this page! There’s just one pretty important rule to follow on this page:
NO ACADEMIC FRAUD!
Academic fraud means cheating on your quizzes, tests, labs, and assignments by using answer keys or by purely copying another person’s work (aka plagiarism). Please do all of your work by yourself! Even if someone gives you the step-by-step solution, do it again yourself so you can understand how the solution was reached or why something specific was done in a specific step.
To those wishing to help others, try to focus more on helping the BlogClanner reach the answer themselves 🙂 Teach them the methods or reasoning that’ll lead to the solution. Just giving them the answer might not teach them how to do similar questions in the future!
As the old saying goes,
Give a man a fish, and he eats for a day. Teach a man to fish, and he eats for a lifetime.

But what’s the square root of 4?
Since a square root is a number multiplied by itself, the square root of 4 is 2, because 2×2=4. You can apply this to pretty much any number by determining which number multiplies to it, like 4×4=16, or 5×5=25.
Hope this helps!
I was being sarcastic… I’m in 10th grade
Oops, sorry! There was no way to tell you were being sarcastic-
The squares of integers (positive whole numbers) are called perfect squares. 4, 9, 16, 25, 36, 49, 64, 81, 100… It’s easy to find the square roots of those. But how do you find the square root of a number that’s not a perfect square? I cheat and use a calculator, but I’m sure there’s a method that I don’t remember. The √3 = 1.732050808
You don’t have to be an apprentice to comment here! It’s for everyone who needs help!
the square root of 4 to 100 digits is 2.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
hope this helps 😇🥰
Plus or minus 2
It’s 2 🙂
not necessarily school, but does anyone have any tips for doing polyrhythms? i’m not planning on learning percussion any time soon, but i still have to do polyrhythms on the piano (they’re pretty useful in music production too) and they keep tripping me up with the triplets and stuff 😛
while we’re here, does anyone have any tips for creating chord progressions? i’m good with most of it, like the circle of chords and the major and minor and the different big jazz chords, but i’m not sure how to apply them in my own music without it sounding like i just learned what chords are
thank you in advance!!!
To take chord progressions first, I strongly recommend this book Making Changes: A Practical Guide to Vernacular Harmony by Eric Salzman and Michael Sahl. https://www.amazon.com/Making-Changes-Practical-Vernacular-Harmony/dp/0793555698
It explains in detail how chord changes work in various forms of popular music—blues, folk, rock, country, jazz—by taking a tune and arranging it in various styles. I have been composing for over 50 years and I couldn’t tell you half as much as you would learn from this book. Worth every penny of its price.
Meanwhile, just a few tips to get started:
There’s never just one right way to harmonize a tune, though, of course, there are better and worse ways, in the context of the style that you’re working in. And what chords you choose are very much a matter of style.
Be aware of the difference between tonal progressions—e.g., those using II-V(7)-I or IV-V(7)-I (a lot of basic rock ‘n’ roll uses just IV, V, & I)—and modal progressions that emphasize scale degrees like III, VI, and VII (especially in minor modes). Making Changes can teach you much more about this than I possibly could here.
The obvious thing to do is to choose chords where the melody note that you’re harmonizing is one of the tones of the triad. There’s nothing wrong with that, but also try chords where the melody note may form a 6th, 7th, or 2nd/9th with the root of the chord. This produces a different effect and is equally valid.
Try analyzing the chord changes in tunes that you like.
(I’ll be back later to say something about polyrhythms.)
It’s difficult to teach polyrhythms in print, because you have to hear them and feel them. Nevertheless, here’s a technique that you might find useful. Every polyrhythm is a pattern of beats that is the product of the two meters involved. To take the simplest example, eighth triplets against straight eighths forms a pattern of 6 beats (2×3) with the straight eighths sounding on 1 & 4 and the triplets sounding on 1, 3, & 5. You can practice this with one meter in each hand. When it feels solid you can speed it up and drop the counting and just feel the pattern. Switch the meters off between the two hands, and maybe make up some interesting chord changes to keep it from getting boring.
The same technique will work for any polymeter: 4 against 3 = 12 beats, 5 against 3 = 15 beats, etc. Maybe Osp has some other ideas on how to do this. I know she’s a percussionist. I don’t know whether she’s reading here, but if not, maybe one of the other mods could flag her.
Hi! Percussionist here who knows 0 music theory <3
As WhiteWhiskers said, the best way to do polyrhythms is to feel them. I know the feel of 3 on 2 and 3 on 4 from practice, and 7 on 4 because of Death of a Bachelor by P!TAD which features the brass playing a rhythm based around septuplets in the breakdown (funny way to figure out 7 on 4 lol, not that I've ever needed it)
However, for other polyrhythms, I wish I could say subdivision could fix everything, but it only really works for simpler polyrhythms. Even for stuff like 5 on 4, you'll need to subdivide by 20 which is... ugly to say the least (or 10, but that's still pretty horrific for my small brain). I know someone who had to play a 5 on 4 on 3 whole band polyrhythm in a piece, and he found a visual aid on Youtube to practice along with. Just finding recordings or visual of the polyrhythm I reckon is the best way, and just placing the notes in regard to the beat is what works for me.
As for chords… just use I V vi IV because that’s the only chord progression that matters <3 /j
I hate the maths (pRoVe a triangle is a trangle-IT JUST IS AGH)
ANYWAY- Does anyone have tips on remembering lines of reflection, without looking back at notes? I know HOW to do it, but I really need to remember how 😭
do you mean like x axis and y axis?? i just remember that if something is reflected over an axis, the value of the other variable becomes negative
like if the point (4, 6) was reflected over the x axis then its new coordinates would be (4, -6)
idk if that helped rip
The best way I can think of is to remember that, when reflected over an axis, the corresponding x or y coordinate becomes negative!
Example: (5,7) reflected over the y-axis would become (5,-7), and reflected over the x-axis is (-5,7). This also works in reverse for negatives, so (-4,-9) reflected over the x-axis would be (4,-9).
Hope this helps! Good luck!
I was gonna help you with the ‘pRoVe a triangle is a trangle’ But i’m like, ooh nvm
Okay does anyone know if male cats can inherit dilution, agouti, and white spotting from their father? I know they can’t inherit coat coloring from their father, but what about those?
I’m not sure, but you should check out this article!
https://kingsize-cat.ru/en/articles/useful-articles/cats-genetics.html
I’m pretty sure they can inherit dilution genes from their father! I’m not sure about the other two.
In algebra we’re solving for x and y with substitution, and two different equations and I do not get it. I thought I did, then I did a bunch of problems and realized I absolutely do not.
so we’re doing stuff like:
2x+2y=38
y=x+3
and I thought I understood how to do it but I kept messing up.
If you’re solving for slope (y=mx+b), then you want to make sure to isolate y! So you would subtract 2x so your equation looks like 2y=2x+38. Then you divide by 2 to get y=x+19, so y is your y-axis, x is your x-axis, m (what you multiply x by, in the original equation if y were simplified it’d be 2) is your slope, and b is 19, or your y-intercept! I hope this is what you’re talking about because we just reviewed slope in my algebra class so I hope this helps lol 😛
Ohh I see. Okay, there is a way that’s pretty easy. Basically, turn one variable into the other. So, for this equation: 2x+2y=38 here are the steps:
If y = x + 3 then y – 3 = x.
Using that, we can re-write the expression and write 2y + 2y – 6 = 38. It is – 6 because there are 2 y’s.
Now, in order to find y, we need to get rid of the -6. To do this, we add 6 on both sides since it’s – 6. Now the equation looks like:
2y + 2y – 6 + 6 = 38 + 6 = 4y = 44. By dividing both sides by 4, we find that y = 11. Remember, y = x + 3 so now we have also found that x = 8.
If you sub in the numbers, it works out!
So now we have found that x=8 and y=11.
Hope this helped!
This is totally off topic, but YOURE A KIT AND YOURE DOING MATH THIS ADVANCED?!?! Lemme guess, are you secretly a genius???
Yes Lily is a genius
…Yes? 😛
Hehe..
Put x+3 in y (because y=x+3), and rewrite the first expression as 2x+2(x+3)=38 -> 2x+2x+6=38 -> 4x=32 -> x=8, y=8+3=11
Hope this helps 🙂
what does dys mean
do you see?
See what?
No it mean Do you see.
Do
You
See
DYS 😛
Thanks for clearing that up Lily xD
Np 😛
Ohhhh sorry 😭 I um, tend to take things literally, as you can tell, hehe…
Nah iz good 😛
i knew someone was gonna say that lol
Not really school-related, but anyone know of any good websites to learn Lithuanian on? I always thought the language was beautiful and I’d love to learn it. Thanks! 🙂
I’d try Duolingo! c:
There’s an app called Ling – Learn Lithuanian that has pretty good reviews! They also have apps for other specific languages, which is how I learned about it 🙂
If anyone needs help with any math up to Year 8 then I can help! 🙂
I could do more extra tutoring. Guys this is for a puppy ok? Its a long story
Oh okay, what subject?
year 8 regular math, geometry, or algebra?
Any 🙂
I’m doing higher than Yr 8 maths (ofc 😛 ), but bro how are you a kit and doing Yr 8 maths 😭
2 words, I’m Asian (Weeel technically 3 words coz I’m is I am buuut 😛 )
Violin’s such an exhausting and hard instrument for me 🙁 anyone have any tips?
Sorry I don’t play violin… it sounds very pretty tho. OH and it has strings.
Very educated on the violin, I am.
*claps*
Uhhh I’d be happy to give tips I’d guess?
Except that I am feeling like a mouse brain as to what kind of tips I will give?
General tips are appreciated, but mostly just how to not sound all squeaky and raspy, thanks!
What are you having trouble with? I know some fantastic violin players, so I can ask them some questions
Not for school but just out of interest I would love to learn the history of the Indigenous people of your nation. We only learn Australian history in class, and so I want to learn more about other country’s First Nations people.
(Sorry if I callled them something they don’t prefer to be called. That’s why I’m here! To learn!)
So…. Enlighten me!
Around where I live, the Shawnee tribe used to roam. They, like many people Indigenous to North America, were relocated to reservations by the U.S. Government. The tribes out in the Midwest were nomads, following the buffalo. They used the buffalo for everything. Their hides were used to make blankets and teepees, which are easily portable tents, and I think they used horns to make weapons. Buffalo were, of course, also used for food. The Trail of Tears, which was used to force out thousands of Native Americans from their homes, runs through parts of my state. The U.S. government used unfair treaties to force tribes out. In particular, there was the Cherokee, whose tribe had to be split up along the route.
There are hundreds, if not thousands, of tribes Native to the Americas, and I suggest researching them if you’re interested!
Related to Australian History but I never liked how when I was in primary school, we only ever learnt abt the First Fleet and nothing more about Aboriginal people or other major events in Australia. Idk if that’s changed since I left PS, but I never liked how we just focused on a slither of colonial history.
So if toms can only inherit coat coloring from their mother, how do they inherit recessive coat genes such as chocolate brown? They need a copy from both parents, right? So how do they get it if they can only inherit it from one?
The answer is simple-he gets both copies from his mother.
From my understanding, recessive genes don’t have to come from both parents. You just need two copies, and remember, mom still has two X chromosomes.
We know that zygotes develop via mitosis. During this process, the amount of chromosomes doubles to 92, then splits back into 46.
My presumption is that a male inherits one piece of DNA from his mothers first chromosome, and one piece of DNA from her second, and those two halves merge into one chromosome.
If both chromosomes contained genetic information coding for chocolate, the tom will be chocolate.
That’s how I understand it, anyway 😛
tysm!
Hi guys!!
