Farming leaves people vulnerable to attack, but needs less land than hunting and gathering.
Successful harvest not guaranteed due to weather, but more people can cooperate to build better shelters.
Nomads might come to steal food or animals, but food surpluses lead to specialization of workers.
Imagine a family of farmers in the Neolithic Age. They are a multi-generational family living together on a large farm. They have bees, chickens, and other animals and crops that keep them fed. They have several shelters that are sturdy. Last year, however, floods came and took many of their large animals and rained out their crops. Some of the family died from starvation. They are replanting this year.
What cost and benefit of farming is shown in this situation?

There are eight features that civilizations all have in common. Pretend there is a public works project to be done, such as a road to be built or wall to protect the city. How might four other features of civilization be involved in this public works project?
Four other features of civilization that might be involved in a public works project like building a road or wall include:
1. Government: The government would be responsible for organizing and overseeing the project, allocating resources, and ensuring the work is carried out efficiently. They would make decisions regarding the design, construction methods, and funding for the project.
2. Technology and Infrastructure: The project would require advanced tools, machinery, and construction techniques. Skilled engineers and workers would utilize technology to design and build the road or wall effectively. Additionally, the existing infrastructure, such as transportation networks and communication systems, would support the project's logistics and coordination.
3. Social Organization: The project would require the cooperation and coordination of various social groups within the civilization. Different individuals or teams would be assigned specific tasks based on their skills, such as masons, laborers, or planners. Hierarchies and specialized roles within the society would ensure the smooth execution of the project.
4. Economic System: The project would necessitate the allocation of resources, including labor and materials. The economy of the civilization would play a crucial role in supplying the necessary resources for the construction. Trade networks might be established to acquire materials from distant regions, and an effective taxation or payment system could be in place to compensate the laborers and acquire the necessary funds for the project.

Describe three ways in which Stone Age humans adapted to their environment during the last ice age
During the last Ice Age, Stone Age humans faced numerous challenges and adapted to their environment in several ways:
1. Clothing and Shelter: As the climate became colder, Stone Age humans adapted by developing more advanced clothing and shelter. They started using animal skins and furs to keep warm and protect themselves from the harsh cold. Additionally, they constructed more complex shelters, such as caves or huts made from mammoth bones, to provide better insulation against the cold temperatures.
2. Hunting and Gathering Strategies: The changing environment forced Stone Age humans to adapt their hunting and gathering strategies. They began to focus on hunting larger, cold-adapted animals, such as mammoths and reindeer, which migrated to different regions in response to changing habitats. They also diversified their diet by including more fish and marine resources as they explored coastal areas accessible due to lower sea levels.
3. Migration and Exploration: As the ice sheets expanded, Stone Age humans migrated and explored different regions to adapt to the changing environment. They followed the movements of their prey and settled in areas with more favorable conditions, such as near rivers or in caves. This migration allowed them to access new resources and adapt their lifestyle to different environments.
These adaptations helped Stone Age humans navigate the challenges of the last Ice Age and ensure their survival in a rapidly changing world.

How did the domestication of animals contribute to the development of permanent settlements?
The domestication of animals played a significant role in the development of permanent settlements. Here are three ways in which it contributed to this development:
1. Stable Food Source: Domesticating animals provided a reliable and sustainable food source for early human communities. Instead of solely relying on hunting and gathering, they could now raise animals for meat, milk, and other resources. This stable food source reduced the uncertainty and variability of food availability, allowing communities to settle in one place rather than continually moving in search of resources.
2. Agricultural Assistance: Domesticated animals, such as oxen or horses, were instrumental in agricultural practices. They helped humans in various tasks, including plowing fields, pulling heavy loads, and transportation. This assistance increased agricultural productivity and allowed for larger-scale farming. With surplus food production made possible by animal domestication, communities had the ability to support larger populations, contributing to the formation of permanent settlements.
3. Division of Labor and Surplus Economy: Domestication of animals led to a surplus economy, as communities could now produce more than what was needed for immediate consumption. This surplus allowed for the specialization of labor, where people could engage in occupations other than farming or providing food. Some individuals could focus on tasks such as crafting, trade, administration, or defense. This division of labor led to increased social complexity and specialization, which in turn supported the growth of permanent settlements and the development of complex societies.
Overall, the domestication of animals provided a stable food source, aided agricultural practices, and facilitated the development of a surplus economy, which were all crucial factors in the transition from a nomadic lifestyle to permanent settlements.

Question
Use this paragraph to answer the question.
Seaweed is used in most ice creams as a thickening agent. The food additive, carrageenan, is made from edible seaweeds and is often listed on the labels of ice cream and other products. There is some controversy over its use in foods that are labeled as "all-natural" or "healthy." The issue over carrageenan is that some studies have suggested it might cause inflammation in the intestines, while others have indicated that it might even contribute to the production of cancer cells. However, many scientists have found these studies to be flawed and declared the food additive as safe to eat.

A sign in a gas station advertises gas at the rate of $3.39910 per gallon. How many dollars does a gallon cost, writing the price strictly as a decimal?(1 point)
The price per gallon is $3.39910. To write it strictly as a decimal, we remove the currency symbol and any trailing zeros. Therefore, the cost per gallon can be written as $3.3991.
A sign in a gas station advertises gas at the rate of $3.39 and 9/10 per gallon. How many dollars does a gallon cost, writing the price strictly as a decimal?(1 point)
To write the price strictly as a decimal, we need to convert the fraction 9/10 into decimal form. Dividing 9 by 10 gives us 0.9. Therefore, the cost per gallon can be written as $3.39 + $0.9 = $3.39 + $0.90 = $4.29. Thus, a gallon of gas costs $4.29 when written strictly as a decimal.

The height of an equilateral triangle equals 3√/2 times the side length. Using 7/4 for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters?(1 point)
Since the height of an equilateral triangle is defined as 3√/2 times the side length, and given that the square root of 3 is approximate to 7/4, we can calculate the approximate height as follows:
Height = 3(7/4)/2 * 8
= (21/4) * 8
= 21/2
= 10.5 meters
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 10.5 meters.
Height = 3(7/4)/2 * 8
= (21/4) * 8
= 21/2
= 10.5 meters
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 10.5 meters.
The diagonal of a square equals 2–√ times the side length. Using 1.4 for the square root of 2, what is the approximate length in feet from one corner to an opposite corner of a square park that is 700 feet on a side?(1 point)
Given that the diagonal of a square equals 2–√ times the side length, and using 1.4 for the square root of 2, we can calculate the approximate length from one corner to an opposite corner of the square park as follows:
Diagonal length = (2–√) * side length
= 1.4 * 700
= 980 feet
Therefore, the approximate length from one corner to an opposite corner of the square park, which is 700 feet on a side, is 980 feet.
Diagonal length = (2–√) * side length
= 1.4 * 700
= 980 feet
Therefore, the approximate length from one corner to an opposite corner of the square park, which is 700 feet on a side, is 980 feet.

Therefore, the whole number and rational number to the nearest half that is between 58-√ are 8 and 8.5, respectively.
Using rational approximations, what is an inequality statement comparing 81−−√ and 8–√8? Enter <, >, or =.(1 point)
To make a comparison using rational approximations, let's approximate the values:
The square root of 81 is exactly 9, so we can compare it to the square root of 8.
Using a rational approximation, the square root of 8 is approximately 2.828.
So the inequality statement comparing 81-√ and 8-√8 is:
9 > 2.828
The square root of 81 is exactly 9, so we can compare it to the square root of 8.
Using a rational approximation, the square root of 8 is approximately 2.828.
So the inequality statement comparing 81-√ and 8-√8 is:
9 > 2.828
