kiruha [24]

Answer:

Therefore the value of the car after 10 year will be = $4,845.34

Step-by-step explanation:

A new car is purchased for $17900. the value of the car depreciates at 12.25% per year.

Since the value of the car depreciates therefore the amount of the car is

A= P(1-\frac{r}{100})^n}

    =17900(1-\frac{12.25}{100})^{10}                [  p = $17900, r = 12.25% and n =10 years]

    = $ 4,845.34

Therefore the value of the car after 10 year will be = $4,845.34

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.
