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.

What is the length of the side of a right triangle that has a side length of 12in and a hypotenuse that measures 15ft
Viktor [21]

Answer: 14.96ft


Step-by-step explanation:

  1. To solve this exercise you must apply the Pythagorean Theorem, which is:

a=\sqrt{b^{2}+c^{2}}

Where a is the hypotenuse, and b and c are the other sides of the triangle.

2. You have that the sides given measures 12 inches. 1 feet has 12 inches. Therefore, this side measures 1 feet.

2. Then, when you  solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of  the side of the rigth triangle is:

 b=\sqrt{(15ft)^{2}-(1ft)^{2}}

b=4\sqrt{14}=14.96ft
