School Help Club!

This is a club where anyone can answer other people's school questions.
I've got a question. Can anyone tell me how to convert fractions to decimals?:happy:

[RouteMaster]

Divide the top line (numerator) by the bottom line (denominator).

[DratiniLover]

Thanks!:happy:

[InvertrevnI]

Wow, you had a good idea. o_o

How do you find thew square root of a number?(Test, I know this)

X the number by itself.:happy:

You take the sqaure root using the square root button on a calculator, or easier in the long term learn the first few square numbers; 1,4,9,16,25,36,49,64,81,100,121,144.

Thats squaring. Matt is right, that is the easy way.

Hello. I have a question about music. Okay, so when analyzing tonal music on the first level, you would have a plagal succession of tonic to dominant preparation to tonic once more. So, you would probably just list those as being the chords. On the second level, however, what would happen to passing and/or neighbour non-chord tones? Thanks in advance!

[Seven]

Obviously, any non-chord tones you have on the first level will ultimately disappear on the second, seeing as they're not truly part of the chord. The plagal succession will then collapse to a large tonic chord.

If you need further help, I could write the theme tune, sing the theme tune...:D

Thank you! Wow, now I realize what a silly question that was. "What color is the sky?" :goofy:

Here's a question:
What is 34x68=?:happy:
Don't use a calculator for this question!:crackup:

[Espeon Rinage]

It is 2312.

[DratiniLover]

It is 2312.

You're right!:surp:

[Espeon Rinage]

It was simple.

first i did 34 X 2 = 68

then i did 34 X 70 = (for this you times 34 X 10 then X that by 7) 2380

but then,

2380
- 68
________

2312

[DratiniLover]

That's a good way to work it out.:happy:

[Espeon Rinage]

That's a good way to work it out.:happy:

Im 2nd in my class with Maths

[RouteMaster]

I used long multiplification; multiplying 34 first by 8 and then seperately by 60 and adding both answers (272+2040) to give 2312.

That's a clever way to work it out.
Anyone got a question?:wink:

I just did that in my head.

I have a question:

If a car can accelerate from 0-60 in 5.23 seconds. Assuming it continues to accelerate at this rate; after 17.6 seconds what will be it's current speed in mph?

I'm not sure about the answer on this question.:confused:

[DratiniLover]

Can you tell us the answer?:happy:

I have a question:

If a car can accelerate from 0-60 in 5.23 seconds. Assuming it continues to accelerate at this rate; after 17.6 seconds what will be it's current speed in mph?

The car's average acceleration over 5.23 seconds is:
60 mph / 5.23 sec = 11.472 miles per hour per second (approximately)

To find the answer to the problem, you just multiple that number by 17.6 seconds:
(60 mph / 5.23 sec) * 17.6 sec = 201.912 mph (approximately)

You have a very fast car going almost 202 mph.

Correct, though it can be done easier.

Just see how many times 5.23 fits into 17.6.
17.6/5.23 = 3.365

Multiply this by 60.
3.365 * 60 = 201.912 mph.

[DratiniLover]

I'm not good when it comes to __m/km Per hour... :goofy:
Anyone got another question?

[HauntedPast]

17.6/5.23 = 3.365

Multiply this by 60.
3.365 * 60 = 201.912 mph.

You are indeed correct as well. I had thought of that way, but I decided to go the other way because it makes the units of acceleration (miles per hour per second) and speed (miles per hour) slightly more clear. You way works perfectly, but I was trying to show acceleration. It is good to have a few different ways of doing it.

Here's an interesting problem I found on a website:
How many +'s (addition signs) should be put between digits of the number 987654321 and where should we put them to get a total of 99?

[DratiniLover]

I still don't understand km/m.:goofy:
