Question

can someone help me please?


A town of 20,000 people in Germany generates 0.95 kg per person per day of MSW. A town of the same size in the US generates 1.9 kg per person per day of MSW.
1. How much MSW is generated in each town daily and weekly?
2. How many trucks would be needed to collect the waste twice weekly? The trucks each have a capacity of 4.5 metric tons. And operate 5 days per week. Assume that the trucks average two loads per day at 75% capacity.
3. If the towns recycle waste at 16% (Germany) and 23% (US), determine the mass and volume of MSW that enters the landfill daily

Answer 1

1.
Germany:1900kg daily
133000kg weekly.
US: 3700kg daily
266000kg weekly.

Answer 2

so far i have that part

Answer 3

how do i solve for 2.?

Answer 4

First determine how many kg(s) in 1 ton. and then multiply by 4.5 and then by .75

Answer 5

1000kg in 1 ton.

Answer 6

So
1000*4.5=4500*.75=3375

Answer 7

That's how many kg in one load.

Answer 8

ok gotcha. i'm sorry i'm not to good with this stuff

Answer 9

It's fine. This is how my math class was in 4th grade. I hate advanced math.

Answer 10

so that is what we get for problem 2 1375

Answer 11

3375

Answer 12

Not quite. See 3375 is for one load and 1 truck averages 2 loads a day.

Answer 13

yah i never have been good with word problems

Answer 14

okay so let me see...

Answer 15

Hold on I have to change my baby real quick. hahaa. I'll be right back.

Answer 16

okay

Answer 17

if we have two loads we get 67500 as the final answer correct? let me know when you get back :)

Answer 18

6750 is how much total one truck gets a day. So take Germany for the first part
133000kg is how much they produce weekly
So divide by 2 since they will come twice weekly.
66500
then divide that by 6750
66500/6750=9.85
So you will need 10 trucks.

Answer 19

alright got it

Answer 20

Now that's just for Germany. For the US
266000kg is how much they produce weekly.
So divide by 2 since they will come twice weekly.
133000
then divide that by 6750
133000/6750=19.7
So you will need 20 trucks.

Answer 21

okay

Answer 22

That's #2. Here's it completely written out.
First determine how many kg(s) in 1 ton. and then multiply by 4.5 and then by .75
1000kg in 1 ton.
So
1000*4.5=4500*.75=3375
That's how many kg in one load.
3375 is for one load and 1 truck averages 2 loads a day.
6750 is how much total one truck gets a day. So take Germany for the first part
133000kg is how much they produce weekly
So divide by 2 since they will come twice weekly.
66500
then divide that by 6750
66500/6750=9.85
So you will need 10 trucks.
For the US
266000kg is how much they produce weekly.
So divide by 2 since they will come twice weekly.
133000
then divide that by 6750
133000/6750=19.7
So you will need 20 trucks.

Answer 23

okay

Answer 24

3. If the towns recycle waste at 16% (Germany) and 23% (US), determine the mass and volume of MSW that enters the landfill daily

Germany:1900kg daily

US: 3700kg daily

3. So for this one we do
Germany:
1900*.16=304kg recycled material
So 1900-304=1596kg which is the amount of waste.
US:
3700*.23=851kg recycled material
So 3700-851=2849kg which is amount of waste.

Answer 25

see that's were i messed up i had 19000*.16=3040 lol

Answer 26

Hahaa.

Answer 27
