Question

WILL MEDAL AND FAN

The formula Q = MCT where Q = heat flow, M = mass, C = specific heat, and T = change of temperature is used to calculate heat flow. Solve this formula for T.

T = Q – MC
T = Q + MC
T = QMC
T = Q divided by the quantity M times C

Answer 2

@HelpBlahBlahBlah

Answer 3

@IrishBoy123 could you help?

Answer 4

\(Q = MCT\)

you want: \(T = something\)

so you're gonna have to start dividing each side by something, right?

Answer 5

ok... yes

Answer 6

so do it!!

divide each side by something that gets you T = [the answer] :p

Answer 7

q/t = mc/t?

Answer 8

@IrishBoy123

Answer 9

hi

Answer 10

no :(

\(Q = MCT\)
\(\frac{Q}{T} = \frac{MCT}{T} = \frac{MC}{1} = MC\)

not that helpful, is it?

you could try
\(\frac{Q}{M} = \frac{MCT}{M} = \frac{CT}{1} = CT\)

and do something very similar again

Answer 11

ok... so I am still confused, just a whole bunch of letters

Answer 12

@IrishBoy123

Answer 13

AHH I NEED HELP ASAP

Answer 14

" just a whole bunch of letters"

the answer is supposed to be a whole bunch of letters :p

and algebra is a whole bunch of letters too

it's not easy so don't worry about it - but i cannot just do it for you.

someone else might, or someone else might be better at explaining. i'd say go back and look at the bunch of letters and see where we got to just by doing the same thing to each side of the equals sign.

Answer 15

then finish it off

Answer 16

I dont want the answer, I just need to understand it better, and I want you to help me eliminate the wrong answer choices...

Answer 17

we can start from the suggestion of @IrishBoy123
so we can write:
\[\Large \frac{Q}{M} = CT\]

Answer 18

@briannam568

Answer 19

i want a medal

Answer 20

now if we divide both sides of that above equation, by C, we get:
\[\Large \frac{Q}{{MC}} = \frac{{CT}}{C}\]
please simplify @briannam568

Answer 21

ok

Answer 22

how do I simplify that? Ive been trying for twenty minutes? @mathstudent55

Answer 23

@IrishBoy123

Answer 24

on the RHS, you have C on the top and bottom of the fraction.

what to do?

Answer 25

you cross it out, since it is canceled out, right?

Answer 26

@Here_to_Help15

Answer 27

@ganeshie8

Answer 28

^Right

\[\large \frac{Q}{MC} = \frac{\cancel{C}T}{\cancel{C}}\]

So what do you have left?

Answer 29

Q/MC=T!! OHH THANK YOU SOOO MUCH!

Answer 30

"you cross it out, since it is canceled out, right?"


indeed, you did it

well done
