Answer:
a) attached
b) 100 square inches, 1/4 of the total
c) square root of area
d) multiply by 4
Step-by-step explanation:
a) A diagram is attached
__
b) If the total area consists of 4 squares of the same size, then the area of one square will be 1/4 of the total area. 1/4 of 400 square inches is 100 square inches, the area of one square.
__
c) The area of a square is the square of the side length. You find the side length by finding the square root of the area. √(100 in²) = 10 in, the side length of each square.
__
d) The rectangle is 4 squares laid side by side, so its length is 4 times the side length of one square: 4×10 in = 40 in.
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](https://tex.z-dn.net/?f=C%20%3D%2016.2%2A10%2C000%2A10%20%3D%201%2C620%2C000%5C%20m%5E3)
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](https://tex.z-dn.net/?f=V%3D52%2A%285%2A0.5%2A765%29%5C%5CV%3D99%2C450%5C%20m%5E3)
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](https://tex.z-dn.net/?f=L%3D%5Cfrac%7BC%7D%7BV%7D%3D%5Cfrac%7B1%2C620%2C000%7D%7B99%2C450%7D%20%5C%5CL%3D16%2C3%5C%20years)
The landfill has an expected life of 16.3 years.
The first step to determine the percentage of increase is to
compute for the difference of consumer price index in value.
231.11 (consumer price index for 2012) – 211.4 (consumer
price index for 2007) = 19.71 (increase)
To compute for the percentage of increase, you need to
compare the increase to the consumer price index for 2007.
19.71/211.4 = 9.3% increase
