need help on whole thing

@forest saddle

[forest saddle]

hello

[ember inlet]

Do you... not understand how to read the chart?

[forest saddle]

bruh

[obtuse gazelle]

just dont get the question

[forest saddle]

dont patronize the kid 😭

ok first fill ABC

[ember inlet]

Do you or do you not understand how to read the chart?

[obtuse gazelle]

thats all u need to fill

[obtuse gazelle]

i do

[forest saddle]

no that's not all you need to fill but first get A B C

[obtuse gazelle]

a=81 b=100 c=90.25

@forest saddle

[ember inlet]

...okay then. So then I guess you didn't need help?

[obtuse gazelle]

question b

no clue what that means

[ember inlet]

...it means "rounded to the ones place".

bru

[obtuse gazelle]

?

[forest saddle]

i will close it

dont worry

[obtuse gazelle]

kk

question b only

[robust wasp]

Do you have the answer to a?

[obtuse gazelle]

ye

[robust wasp]

How did you get it?

[obtuse gazelle]

6775 div 2.5

[robust wasp]

Cool that sounds right

How do mass, density and volume relate exactly then?

[obtuse gazelle]

do ya do6775 times 1,9?

[robust wasp]

If V =volume, m=mass and d =density, what is the formula for the density?

[robust wasp]

Ok, so what does the question want you to calculate?

[obtuse gazelle]

mass

[robust wasp]

So if you get mass on one side by manipulating this equation you get the answer

[obtuse gazelle]

so d x v ?

@robust wasp

[robust wasp]

Yes!

[obtuse gazelle]

kk

thx

so 6775 x 1.9 ?

[robust wasp]

You can check it by doing the same with the units too

[obtuse gazelle]

and i write full number ?

[robust wasp]

No that's the mass times volume

[obtuse gazelle]

so 6775 div 1.9 ?

[robust wasp]

That's mass / volume, that's density

What did you get from answer a?

[obtuse gazelle]

answer or what ?

[robust wasp]

No what does that number mean?

[obtuse gazelle]

cubed

[robust wasp]

Read question a, the answer to my question is in there

[obtuse gazelle]

so 6775 div question a ?

@robust wasp

[robust wasp]

No, that's volume

[obtuse gazelle]

wtf

im confuesed

[robust wasp]

And that is the mass of the marble from question a, not b

[obtuse gazelle]

dont understand lol

so all i know is D x V

[forest saddle]

@robust wasp you are an angel for this 🙏

[robust wasp]

In this question there's two different pieces of marble, one has a mass of 6775 and volume 2.5 m^3. That's the one from a.

[obtuse gazelle]

ye

[robust wasp]

You used those numbers to calculate the density of marble

[obtuse gazelle]

mhm

[robust wasp]

Which you did by dividing mass over volume

That number tells you how many kg each m^3 of marble weighs

In part b, they tell you about a piece of marble that is 1.9 m^3 in volume. They ask you what it's mass is.

Since you know the density, you can now work backwards towards this piece's mass.

[obtuse gazelle]

i know the density ???

lol im so confused

[robust wasp]

The density is the number you got in a)

[obtuse gazelle]

oh kk

so u divide ?

[robust wasp]

Wait, I'm grabbing a pen and some paper

[obtuse gazelle]

for ?

[robust wasp]

To write it on paper, that's more clear than in discord

Nvm I'll do it like this

[obtuse gazelle]

so u div ?

[robust wasp]

Density $d=[kg/m^3]$, it signifies how heavy something is per how big it is

[frail meadow]

Lumberdude #LeaveWolfAsHeIs

[robust wasp]

So a density of 1 kg/m^3 means that every 1 m^3 of something that I have it weighs 1 kg

So if I have 2 m^3 it weighs 2 kg

[obtuse gazelle]

what is the little triangel ?

[robust wasp]

It means "to the power of"

[obtuse gazelle]

kk

[harsh trail]

Hm, not the best idea to use d for density, though...

[robust wasp]

Rho will make it more confusing at this point

[harsh trail]

I mean, I know that it was used before, but it's quite archaic and can be confusing.

[robust wasp]

I agree

[harsh trail]

Hm... I believe using d for it is more confusing.

[obtuse gazelle]

can u just tell me answer and ill work back ?

[harsh trail]

Well, by definition, the density of a uniform body with volume V and mass m is ρ = m/V.

[obtuse gazelle]

so mass div volume ?

[harsh trail]

Yes.

[robust wasp]

We have the density, which was 6775 kg/2.5 m^3

[robust wasp]

Yes

[obtuse gazelle]

and mass is answer for a ?

[harsh trail]

Oh, it's aluminum, I see.

[robust wasp]

No the answer for a is the density that you use for question b

[harsh trail]

What do you mean? You're finding density in (a), not mass.

[obtuse gazelle]

so ???

[harsh trail]

Well, what did you get?

[obtuse gazelle]

im still confused

whats the mass density and volume

[robust wasp]

So in this picture we have everything except the mass. We have the density $2710 kg/m^3$ and the volume $1.9 m^3$

[frail meadow]

Lumberdude #LeaveWolfAsHeIs

[harsh trail]

Wait, you do not know what mass, volume and density are at all?

Huh... That's a problem.

[obtuse gazelle]

so u div 2710 to 1.9 ?

[robust wasp]

No

[obtuse gazelle]

well i do but it confusing cuz it 10 pm at night

[harsh trail]

Oh, phew...

[robust wasp]

We can divide mass/volume, not density/volume

[harsh trail]

Well, anyway.
We have ρ = m/V. Try finding m from here.

[obtuse gazelle]

and its a friday

what p ?

[harsh trail]

What?

[robust wasp]

Density

[forest saddle]

say density

[obtuse gazelle]

ok

[harsh trail]

Oh, you meant ρ.

[forest saddle]

please no dont go there

he cant handle that

[obtuse gazelle]

so density = madd div what v ?

[harsh trail]

Hm? What do you mean?

[obtuse gazelle]

nvm

[forest saddle]

he is not

up there

yknow?

[obtuse gazelle]

so density = mass div volume ?

[forest saddle]

yes

[harsh trail]

No, I do not know.

What do you mean?

[robust wasp]

Yes

[obtuse gazelle]

ok

[forest saddle]

he's having trouble

[obtuse gazelle]

so mass is 1.9 ?

[obtuse gazelle]

no shit

[robust wasp]

No that's volume

[obtuse gazelle]

it 10 pm and on friday

[obtuse gazelle]

ok

[forest saddle]

yes exactly

[obtuse gazelle]

and the mass is 2710 ?

[harsh trail]

Well, I can see that, but what exactly do you mean by "don't go there"? Go where?

[robust wasp]

That's density

[forest saddle]

dont go to rho

dont do it

[harsh trail]

What? But that's just density.

[forest saddle]

he cant take it rn

[harsh trail]

What's the problem with it?

[forest saddle]

he cant handle the symbol

not yet

[harsh trail]

What, a Greek letter? Why?

It's just a letter.

[obtuse gazelle]

so 2710 x 1.9 ?

[forest saddle]

try it 😭

[robust wasp]

YES!

[harsh trail]

Don't forget about units.

[obtuse gazelle]

oml

its 10pm for god sake

so is it right ?

[harsh trail]

You keep repeating that, but I don't get what exactly get you mean by that.

[robust wasp]

Yes it is

[obtuse gazelle]

its right /?

[robust wasp]

Yes it is

[obtuse gazelle]

FINNALLY

IS THERE ANOTHER STEP ???

[robust wasp]

Lord is actually correct though. What are the units

[obtuse gazelle]

iit this the ans ?

[robust wasp]

Looks like it is

[obtuse gazelle]

km/m3

maybe

nvm

kg ?

next question

:/

[robust wasp]

Yes! Since you multiplied kg/m^3 and m^3, the meter cubed cancels, leaving us with kg

I really have to go to bed man, is 11:30pm, I've been awake for 20 hours

I have confidence in you, you can do this! 💪

Gn

[obtuse gazelle]

lol

ok

gn

@forest saddle UR UP

help me plis

[normal thicket]

do you remember how the density formula works

[obtuse gazelle]

@ember inlet can u help ?

[normal thicket]

you should at least have learned that in the past 200 messages right

[obtuse gazelle]

D = M div V

?

[normal thicket]

indeed

so can you find M and V?

[obtuse gazelle]

nop

[forest saddle]

bro you have another thread for this exact question 😭

[obtuse gazelle]

yea

[normal thicket]

LMao REALLY??

[forest saddle]

WITH A GUY ACTIVELY HELPING YOU

[obtuse gazelle]

cuz we just finished it

[obtuse gazelle]

he waffaling abt smthing else

[forest saddle]

ITS NOT EVEN DEAD, THERE'S LEGIT SOMEONE TYPING THERE THAT'S HELPING YOU

true

[obtuse gazelle]

it 10pm too much info to take in'

[normal thicket]

holy shit there is

can you only have one thread at a time lmao

wanna close this one @obtuse gazelle ?

[obtuse gazelle]

ok

close thsi and go to other one

[normal thicket]

+close
