Question

Help


A single tree produces about 2.6*10^2lb of oxygen each year. The amazon rain forest has about 3.9*10^11 trees.

About how many ounces of oxygen are produced in the rain forest each day?

4.4*10^ ? oz

Answer 1

1 tree = 2.6 *10^2 lb
3.9*10^11 trees = 2.6 *10^2lbs * 3.9*10^11 = x lbs
16 oz = 1 lb
and you have x * 1lb so to convert that to ozs you would have 16 *x ozs
do you follow?

Answer 2

wait this is for the year
the question asks to find for each day
we just found how many ounces for the year and we know a year = 365 days
can you find for 1 day?

Answer 3

im still really dont understand

Answer 4

note that when doing conversions just need to keep the units in tact. example if you converted from year to day first you would get the same result

Answer 5

read through the post again slowly from the top and let me know where you are stuck

Answer 6

@winsteria please help me!!!!!!!!

Answer 7

ohgod well

Answer 8

i really dont undersatd at alll :(

Answer 9

okay so what you need to do is.

Answer 10

okay so one tree produces 2.6*10^2lb of oxygen a year so you need to take all of the trees that are in the forest which are 3.9*10^11 in all so then you need to divide the amount of all of the trees the forest by ohgod im stuck wait

Answer 11

to be honest, i've never even done this math before but you need to divide the amount of trees in the forest by something (that something we don't know) and then multiply it by 2.6*10^2lb ???

Answer 12

i'm sorry if i'm not much of any help but there are 365 days a year maybe divide that by the amount it produces a year??? idk

Answer 13

lol its ok do you know anyone who might know this?

Answer 14

and thank you so much

Answer 15

i can tag some people for you and yw

Answer 16

@ramiva @Roxeyrai73 can any of you help her with this problem, please she really needs help???

Answer 17

thank you so much

Answer 18

i can't explain it other than how @triciaal did srry

Answer 19

I would say that there are two ways to go about this, you can figure out how much the entire forest produces per year, and then divide by the days (365) to figure out how much it produces per day. Or you can divide the amount an individual tree generates per year by 365, to determine how much an individual tree generates per day, and then multiply that by the number of trees. you should end up with the same answer.

Answer 20

OMG I DONT KNOW

Answer 21

so (2.6*10^2)(3.9*10^11) gives you the total amount of carbon that the amazon produces every year

Answer 22

this gives you 1.014x10^14 lbs. per year

Answer 23

to find lbs. per day we divide that number by the number of days per year which is 365

Answer 24

this is approximately 2.78x10^11

Answer 25

ok so i would find the answer to 1.014x10^14 then divide the answer by 365?

Answer 26

well 1.014x10^14 is just a value but its over 100 trillion so we write it in scientific notation to make it simple. so you just divide the value 1.014x10^14 by 365 to get the answer

Answer 27

okay well thank you for everything guys @winsteria @ramiva

Answer 28

i wish i could have been of more help, i'm sorry D: but did you get the answer or???

Answer 29

yeah i figured it out

Answer 30

now im doing science :/ blah

Answer 31

oh okay that's good and ikr science is just ugh ;-;

Answer 32

yeah it blows

Answer 33

im gonna message you so we can talk there and not on the thread

Answer 34

okay
