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.

Choose what the expressions below best represent within the context of the word problem.
grin007 [14]

Answer:

The given expression "The sum of two consecutive odd integers equals 12." is written as 2x + 1 + 2x + 3 = 12  and numbers are 5 and 7

Step-by-step explanation:

 Given expression : The sum of two consecutive odd integers equals 12.

We have to write the given expression mathematically and solve.

Consider the given expression "The sum of two consecutive odd integers equals 12."

Consecutive odd integers are the odd integers having difference of two in between like 3, 5, 7 etc,

we know odd numbers are of the form of (2m+1)

Thus, let two consecutive odd integers be 2x+1 and 2x+3

Then given sum of  two consecutive odd integers  is 12

mathematically written as,

2x + 1 + 2x + 3 = 12

4x+ 4 = 12

x + 1 = 3

x = 2

Thus, consecutive odd integers are 2(2)+1 = 5

and 2(2) + 3 = 7

Thus, the given expression "The sum of two consecutive odd integers equals 12." is written as 2x + 1 + 2x + 3 = 12  and numbers are 5 and 7
