In your opinion, what was the biggest source of conflict between the United States and tribes living on the Great Plains before and during the Plains Wars? What eventually brought an end to the Plains Wars? Explain your answer in 75 to 100 words.

Answers

Answer:

Vast land

Explanation:

The great plains were the region of Texas, Kansas, Colorado, Nebraska, and Oklahoma. In the 1840s, settlers moved west to the Great Plains as they were looking for gold and land.

Settlers were not the only inhabitant in the Great Plains but also had many Indians tribes. The government tried to get their land and sell it to settlers. Many of the Indians were hunters, not farmers. They relied on nature for their survival. Buffalo lived on the Great Plains, and Indians hunted them for food and other uses.

The destruction of Buffalo herds was the trainloads which allowed white men who shoot bison in the Plains. Bison killed as the government gave the authorization to shoot to clear land for farming and to make Native Indians declined. Native Indians depended on the bison for their fur, skin, meat, and fur.

The Sand Creek Massacre, the Battle of wounded Knee, and Battle of the Little Bighorn were some of the famous battles. The defeat of the Indians brought an end of the conflict with sending them to live in the reservations.

Answer:

The movement of white settlers to the West was a big source of conflict between the United States and the tribes of the Great Plains. The government moved the tribes onto the reservations to make room for US settlement. The tribes’ way of life, including hunting bison across the Great Plains, conflicted with expanding settlement.

In the end, the Native Americans on the Great Plains could no longer find enough food to survive. The bison they hunted disappeared as more people hunted the animals for sport. Though the tribes tried to fight back, US troops didn’t give up their campaign to move Native Americans onto reservations in Indian Territory.

You have recently bought four tickets for $15 each to a professional baseball game. You would have been willing to pay $25 for a ticket, but probably would have bought fewer tickets if that were the case. Calculate your total consumer surplus as area.

Answers

Answer:

$80

Explanation:

Step one:

What is consumer surplus area?

"Consumer Surplus reflects the difference between what a consumer is willing and able to pay for a product, and what the consumer actually ends up paying.

"

The area of surplus is calculated using the formula for the area of the bounded triangle.

Area of surplus =1/2 b*h

where b= the quantity

           h= consumer surplus

Step two:

given data

the quantity of tickets = 4

b=Q-O------------ (from the chart attached)

cost per tieckt= $15

Total cost of 4 tickets= 15*4= $60

the actual price is $60

Since you are willing to pay $25 per ticket

the total amount you are willing to  pay is = 25*4= $100

Consumer surplus = y-p------------ (from the chart attached)

Consumer surplus = $100 – $60

Consumer surplus = $40

Area of surplus = 1/2 x (4) x40 = $80
