OpenStudy (anonymous):

OpenStudy (nubeer):

its 1

OpenStudy (anonymous):

A?

OpenStudy (anonymous):

yea number one is the first graph

OpenStudy (nubeer):

yes A is the answer or graph

OpenStudy (anonymous):

Thanks nubeer could you help me out in another question?

OpenStudy (nubeer):

sure

OpenStudy (anonymous):

A cannery processed 1,445 pounds of strawberries in 4.5 hours. The cannery processed 2,320 pounds in 7 hours. Write a linear equation to model the relationship between the weight of strawberries S and time T. How many pounds of strawberries can be processed in 11 hours?

OpenStudy (nubeer):

hmm ok A cannery processed 1,445 pounds of strawberries in 4.5 hours gives a rate of 321.11 pounds per hour, and the second statement, "The cannery processed 2,320 pounds in 7 hours." gives a rate of 331.43 pounds per hour. Since the rate isn't constant, it isn't exactly a linear process, but the rates are close enough, that you could take an average of the two to estimate it. so S=kT K = rate and rate is = 326.27 so S = 326.27 * 11 S =3588.97

OpenStudy (anonymous):

ok you make everything look easy :)

OpenStudy (anonymous):

so how did you get 326.27?? @nubeer

OpenStudy (nubeer):

i calculated rate.. there were 2 rates can u see it?

OpenStudy (anonymous):

nope thats not it

OpenStudy (anonymous):

oh yea now I see sorry

OpenStudy (nubeer):

331.43 pounds per hour. 321.11 pounds per hour i have just taken the average of this..

OpenStudy (anonymous):

ok so we dnt use both of them...

OpenStudy (nubeer):

yes bcos if it was linear then the rate would be same .. but the rate is not same , its near so we took average

OpenStudy (anonymous):

ok I have to go but that is the answer right? 3588.97

OpenStudy (nubeer):

well i think its right ..

OpenStudy (anonymous):

alright thanks for all your help nubeer

OpenStudy (nubeer):

you're welcome :)
