Answer:

What would the world be like if the car had not been invented:

Explanation:

If the automobile had not been invented, our life would be very different. Firstly, we couldn't make big trips in a short time. We would not have a quick transport option and traveling would be a headache.

However, since automobiles did not exist, there would be no emission of 58% of greenhouse gases. There would be a radical transition to cycling that would benefit the health of the planet and ours. That would lessen the problems of air pollution, not to mention the extra calories we would spend using the bike instead of the car.

Compare the benefits of natural change to ecosystems to the disadvantages.
Ronch [10]
Natural changes to the ecosystem refer to environmental phenomenon that occur naturally. Natural changes include floods, volcanic activity, hurricanes, droughts, and earthquakes. They can be destructive, but they also have advantages.
The benefit of the flood is for example providing nutrients to the soil that were lacking. Also t<span>here may be relocation of fishes and organisms living in water bodies, which improves the ecosystem.
Volcano threatens t</span>he people and animals in the area are threatened, but is has also some advantages, for example:<span>the soil becomes rich due to the nutrients from the volcano. 
</span>Hurricanes result in the destruction to infrastructure and loss of lives, vegetation, and livestock. The advantage is that it lowers the temperature and t<span>he wind will cause the topsoil to be distributed to areas in which it was lacking.</span>

Wittaler [7]

Answer:

Because factories were usually located in cities, industrialization went hand-in-hand with – urbanization. The industrial economy helped create robust growth in the United States for many decades. Plentiful manufacturing and industrial jobs meant that –workers could enter the job market making a good wage. But as the economy began to transform once more, from an industrial to a post-industrial system, the nature of work changed as well. –This led to a decline in industrial jobs: from 18 million in 1990 to –12.4 million by 2017.

Explanation:

a) Industrialization: This term refers to the development of industries, which is characterized by economic growth, more efficient division of labor, mass production, and the use of technological innovations to solve problems.  Industrialization was triggered by the evolution of capitalism and the agricultural revolution.

b) Urbanization: Is the outcome of a process that see the movement of the population from rural areas to towns and cities.  It is usually caused by industrial growth, availability of employment and social amenities, commercialization of activities, modernization, etc.

c) Industrial Economy: This is an economy characterized by the building of industries, where the factors of production are no longer limited to land, labor, capital, and natural resources, but include the use of technology and knowledge.

d) Post-Industrial System: Post-industrial system is an economic system of the period within an industrialized economy or nation witnessing a declining manufacturing sector and increasing activities in services, information, and research, resulting to de-industrialization.

Ruth Palladium bought 10 acres of land and built a house on 2.0 acres. RuPd wanted to raise sheep on the remaining 8.0 acres. If
-BARSIC- [3]

Answer:

\boxed{\text{26 sheep}}

Explanation:

1. Convert acres to hectares

1 ha = 2.471 ac

\text{Area} = \text{8 ac} \times \dfrac{\text{1 ha}}{\text{2.471 ac}} = \text{3.2 ha}

2. Calculate the number of sheep

You can put 1 sheep on 0.125 ha

\text{No. of sheep} = \text{3.2 ha} \times \dfrac{\text{1 sheep}}{\text{0.125 ha}} = \textbf{26 sheep}\\\\\text{RuPd can raise $\boxed{\textbf{26 sheep}}$ on 8 ac}\\

What is the solution of StartFraction 1 Over c minus 3 EndFraction minus StartFraction 1 Over c EndFraction = StartFraction 3 Ov
Bingel [31]

Answer:

  • <u><em>All real numbers except c = 0 and c = 3.</em></u>

Explanation:

The equation is:

   \dfrac{1}{c-3}-\dfrac{1}{c}=\dfrac{3}{c(c-3)}

Since c - 3, c, and c(c - 3) are he denominators, none of them can be equal to zero:

  • c ≠ 0
  • c - 3 ≠ 0 ⇒ c ≠ 3
  • c (c - 3) ≠ 0 ⇒ c ≠ 0 and c ≠ 3.

Now you can multiply both sides of the equation by the common denominator: c (c - 3):

       c-(c-3)=3\\\\c-c+3=3\\\\0=3-3\\\\0=0

That means the equality is valid for all real numbers for which it is defined, which is all real numbers except c = 0 and c = 3.
