5 men working 6 hours a day can dig a trench 180m long in 4 days. How many days would 8 men working 3 hrs a day take to dig a trench 220m long​

Answers

Answer 1

assuming efficiency of each man to dig trench, in one day, for one hour is constant,

[tex] e=\frac{180}{4\times6\times5}=\frac{3}{2}[/tex]

so one man, working for one hour in one day can dig 1.5 m

so 8 men, working 3 hours a day and will take, say $d$ number of days and efficiency will be constant. so,

$\frac32=\frac{220}{8\times3\times d}$

$\implies d=\frac{55}9=6.12$

Compare our government today with the government of Henry viii

Answers

Explanation:

Henry VIII did not have the same approach to government as Henry VII had done. Henry VII was very much a person who wanted to involve himself in the day-to-day running of government – almost in fear that he would lose control of government if he was not in as much control as was possible in those days of limited communication. Henry VIII took a very different approach. He believed that government could be left to trusted men who once they knew the king’s wishes would implement them. Therefore, though Henry VIII was not overly involved in government, his men were actually carrying out his policies. Henry believed that his men were honourable and that loyalty would be their guiding star. Therefore, he did not need to involve himself in government as his trusted and loyal ministers would do it for him. Success was likely to be rewarded. Most, if not all, knew what failure meant.

Henry’s ministers knew that there were only two times in the day when Henry might be available to discuss policy – around the time each day that he took Mass and after dinner. Even then, neither time could be guaranteed, especially the latter. Henry was very good at quickly understanding issues that needed to be answered. While history tends to remember his six wives and infamous temper, it tends to forget that Henry was an intelligent man though probably not as intelligent as he thought he was. He was not the “universal genius” that Erasmus called him either. However, there is little doubt that in the early years of his reign, Henry could easily digest information when it suited his purpose to do so. Keith Randall described Henry as a “shrewd politician”.

In one paragraph, explain why leaders of the women's rights movement decided to model the Declaration of Sentiments after the Declaration of Independence.

Answers

Answer:

Declaration of Sentiments, document, outlining the rights that American women should be entitled to as citizens, that emerged from the Seneca Falls Convention in New York in July 1848. Three days before the convention, feminists Lucretia Mott, Martha C. Wright, Elizabeth Cady Stanton, and Mary Ann McClintock met to assemble the agenda for the meeting along with the speeches that would be made. The Declaration of Sentiments, written primarily by Stanton, was based on the Declaration of Independence to parallel the struggles of the Founding Fathers with those of the women’s movement. As one of the first statements of the political and social repression of American women, the Declaration of Sentiments met with significant hostility upon its publication and, with the Seneca Falls Convention, marked the start of the women’s rights movement in the United States.

Answer:

Humans survived by hunting and gathering

During the vast majority of human history, humans were hunter-gatherers. They hunted wild animals, and gathered fruits, vegetables, and other plants. During this time, humans were nomadic or semi-nomadic, and lived in small groups that have to move around constantly in search for food.

The Neolithic Revolution occurred

The Neolithic Revolution occurred around 10,000 years ago, when humans started to grow crops and domesticate animals. This changed human societies from nomadic to sedentary.

Advanced civilizations developed when People could farm and store a surplus of food

As the neolithic revolution advanced, sedentary human groups became larger, because they now could farm and store a surplus of food. This changes led to the development of advanced civilizations, with important social and economic institutions such as the division of labor, and social hierarchies.

explain how more advanced civilizations were able to develope techonology that allowed their citizens to move away from the river

Answers

The correct answer to this open question is the following.

More advanced civilizations were able to develop technology that allowed their citizens to move away from the river and protected them from flooding.

This technology first, allowed civilization to predict the flooding of the rivers, and then to take advantage of the flooding to increase crop production.

Let's not forget that ancient civilizations such as Sumeria, settled in the middle of two rivers: the Euphrates and Tigris. This represented many advantages to farming but also had its risks, basically, flooding. In the case of ancient Egypt, they settled in the banks of the Nile River, and they were one of the most successful civilizations that developed the kind of technology to avoid disasters due to flooding, and instead, growing good crops. The flooding of the Nile left rich soil to grow quality crops that they traded with other towns. The Egyptians also built underground channels to take the course of the water in times of flooding. Thes minimized the risk of massive flooding of their cities.

Answers

Answer:

a. Reinforced the concentration of poverty in non-white urban neighborhoods.

Explanation:

The Housing Act of 1949 was enacted to reinforce the availability of economical housing schemes for the urban areas after some major move of most people to the suburbs. It also brought a major increase in the construction of the public housing system.

This 1949 Act led to a major increase in the concentration of the poverty level in the urban areas populated by the non-whites. Though this Act was supposed to improve the perception of American housing systems even in rural areas, the planned clearance of slum residency and help in the land development to foster lesser slum areas wasn't a huge success.
