A sanitary landfill has available space of 16.2 ha at an average depth of 10 m. Seven hundred sixty-five (765) cubic meters of s

AfilCa [17]

Answer:

16.3 years

Step-by-step explanation:

1 ha = 10,000 m^2

The total capacity of the landfill is:

$C = 16.2*10,000*10 = 1,620,000\ m^3$

If waste is compacted to twice its delivered density, its volume is half of the delivered volume. Assuming that a year has 52 weeks, the volume of compacted solid waste dumped per year is:

$V=52*(5*0.5*765)\\V=99,450\ m^3$

The expected life of the landfill is given by its capacity divided by the yearly volume:

$L=\frac{C}{V}=\frac{1,620,000}{99,450} \\L=16,3\ years$

The landfill has an expected life of 16.3 years.

People attending a football game either supported the home team or the visiting team. If 1369 of the people attending supported

Anna [14]

Answer:

37%

Step-by-step explanation:

To find the percentage of people that supported the home team, we need to find the total number of people.

This is because the percentage of people supporting the home team will be given by:

Number of people supporting home team / total number of people

The total number of people is the people supporting the home team plus the people supporting the visiting team:

1369+2331=3700

<u>Therefore, our percentage will be:</u>

1369/3700

Plug this into our calculator and we get:

0.37

Convert that a percentage for a final answer of 37%
