Answer:
1) Mining
2) Ranching
3) Commercial Farming
Explanation:
The miners who comes mostly from California and other areas fulfilled the demand for gold and silver in the East. They also contributed in extracting other minerals i.e. copper, zinc, iron ore, lead, and quartz, which were great for the industrial use.
The sheep and cattle ranchers played an important role too i.e. that they produced wool, meat, and leather to satisfy the demands of eastern manufacturers and the consumers.
The farmers contributed by making farming commercial. They sold their crops in home town and internationally which helped the economy to improve.
An overgrown lawn is manicured by mowing it with a lawn mower is an example of physical change. Physical change is a change that affects the physical form of the substance or environment but not its chemical composition. In this example, the lawn is manicured by mowing it, so the physical form would be changed. But, the chemical composition of the lawn was maintained and was not change. So,<span> this is clearly a physical change.</span>

Answer and Explanation:
a. The computation of depreciation for each of the first two years by the straight-line method is shown below:-
Depreciation
= (Assets cost - Salvage value) ÷ Useful life
= ($171,000 - 0) ÷ 25
= $6,840
For First year = $6,840
For Second year = $6,840
It would be the same for the remaining useful life
b. The computation of depreciation for each of the first two years by the double-declining-balance method is shown below:-
First we have to determine the depreciation rate which is shown below:
= One ÷ useful life
= 1 ÷ 25
= 4%
Now the rate is double So, 8%
In year 1, the original cost is $171,000, so the depreciation is $13,680 after applying the 8% depreciation rate
And, in year 2, the ($171,000 - $13,680) × 8% = $12,585.60
