Heh, I get it.

- ParthKohli

\(5 \min 54 \sec = 5 \dfrac{54}{60} = 5.9\)

Is it this?

@ParthKohli
Yeah right.

Im doing a Algebra2 experiment and i have to divide my average time by 10
Here are my times
5 min 54 sec
4min 55sec
3min 30sec
so when i divide these all by 10 do i put the time in decimal form? Like 5min 54 sec= 5.54??

- ParthKohli

Essentially, \(5 \min 54 \sec = {5 } + \dfrac{54}{60}\) as we're expressing the seconds as a fraction.

- ParthKohli

Now, you can simplify \(\dfrac{54}{60}\).

- anonymous

so, 5.9 divide by 10? and i get .59? and that would be my awsner for that one

- ParthKohli

BTW, it'd be dividing 5 min 54 sec by 10, not the vice-versa.

- ParthKohli

Yes, that'd be your answer :) @julliemyers

- anonymous

oh ok then so just to make sure i get the rest correct let me do them and will u check them?

- nubeer

hmm it says to divide the average time by 10.. so that might not be the answer.. first you have to convert all your times into decimal

- ParthKohli

Sure! =)

- anonymous

((10/5) minute) + (54 seconds) = 2.9 minutes

- ParthKohli

Oh, yes.

- ParthKohli

Didn't see that question below.

- anonymous

no i had 3 trials and i have to divide 10 by indivaual times

- anonymous

serach on google divide 10 by 5 minutes and 54 seconds

- ParthKohli

Okay... so can you divide the other times by 10 after converting them and take the average of all figures you get?

- anonymous

hang on ill show u my table

5 minutes 10 seconds divide it by 5 = 1 minute 2 seconds.

- ParthKohli

Oh, so that is the question.

- anonymous

this is the directions
. For each trial, use a stopwatch to record the number of
seconds it takes for the pendulum to complete 10 full swings. Record each time
in the i rst column of the table provided on the next page. Next, i nd and record
the average of the three times you listed. Finally, divide the average time by 10 to
determine the period of the pendulum. Repeat the procedure using two coins, then
using three coins, recording the data in the second and third columns, respectively.
Does it appear that the weight of the bob af ected the period of the pendulum?
What factors other than the weight might af ect the period of the pendulum?

- ParthKohli

So you have to find the average period. It'd be 5 min 54 sec by 10.

- anonymous

yes each collum had their own average time

- ParthKohli

Then I'm afraid you'd have to complete this experiment by yourself.

- ParthKohli

Did you do this experiment?

- nubeer

hmm ok i have a question.. something don't seem right.
in the trial 1 with 1 coin the time u have wrote is for 10 swings?

- anonymous

yes it was in the file i attatched
i just needed help on how i would divide time by 10

- ParthKohli

But that wouldn't be the time for 10 swings.
Though there's a cheat: You can divide it by 3. ;)

- anonymous

add all noted times with seconds as fraction and then divide by 10. here is your answer :)

- nubeer

@julliemyers wel i think the average time u have found for 10 swings in that file is wrong.. u need to check that again.

- ParthKohli

You can add 3 noted times and divide by 3 -- no one would realize :D

- ParthKohli

@nubeer: Seems like julliemyers has summed up the three noted times in the above rows.

- nubeer

yup she did that.. she just forgot to divide by 3

- ParthKohli

Mhm

- anonymous

@nubeer it doesnt say i need to divide by 3 tho?

- nubeer

i know it don't say and it will never say.. the Word Average itself says it..
Average = Total time/ no. of times experiment performed..
means you would add up the time of all the 3 trials and then divide it by 3..
IF INCASE.. there was a 4th trial then you would add all the 4 times and divide by 4... you have to do this where ever the average word comes up

- anonymous

ohh Yea i remeber that. So for ex 5 min 54sec would be 5.54/3 =1.846 then i devide that by 10?? =0.1846????

- nubeer

yes..

- anonymous

ok i think i have got it lol -.-

- nubeer

lol good :)

- ParthKohli

@julliemyers No

- anonymous

@ParthKohli No to what? Im wrong?????

- nubeer

lol that was 5.9 .. the total time.

- ParthKohli

It's not \(5.54\); it's \(5.9\)

- ParthKohli

And you don't have to further divide by 10.

- ParthKohli

Got it? :D

- nubeer

lol she have to divide by 10 to find the time period.. @ParthKohli

- anonymous

Im so confused (-.-)

- nubeer

First add all the time , trial 1,2,3 that would be 5.9 and divide it by 3.. the value you will get you will put that against this row "Average time complete 10 full swings"

- ParthKohli

Oh yes

- nubeer

Now.. the value in this row "Average time complete 10 full swings" you would divide it by 10 and put them in this row "Period of pendulum "

- ParthKohli

@nubeer: My medal increased your SS :P

- nubeer

lol does it ? really? hahah i dont think so.. lol i never work on medals but still thank you...

- anonymous

Im spose to have 3 periods of pendulum times, I dont think i add up all my averages. i think im spose to have 3

##### 1 Attachment

- nubeer

hmmm .. :( not getting you.. ok look the file you have posted and see the row average time for 10 swings what value u have in there?

- anonymous

yes those r the values added of the coin 1 coin 2 and coin 3

- nubeer

ok.. now 5 min 54 secs convert in decimal you will get 5.9 right? you did that before now divide 5.9 by 3... becasue that total time is for 3 trials.. getting it?

- anonymous

i get 1.966666666 = 1.97

- anonymous

so 1.97 would go in the period of pendulum collum???

- nubeer

ok.. good.. now this is average time for 10 swings.. ok?
now for the time period of pendulum.. this means the time period for just 1 swing so u divide 1.97 by 10

- anonymous

.197

- nubeer

yes

- anonymous

Should i have 5.9, 4.9, 3.5In the average collum? Instead of the minutes and seconds or should i leave it how it is

- nubeer

hmm i told u these are not average.. 5.9/3 would be the aveage so 1.97 mins is the average of 10 swings.

- anonymous

ok thats what i was wondering lol i feel stupid but i understand it now lol

- nubeer

lol no worries..

- anonymous

ok so i fixed it take a look

- nubeer

yup looks ok now.. this all are in mins. :)
