. If its height is 21 units, find its radius.

Answers

Answer 1

The formula for the volume of a right cone is V = (1/3)πr^2h, where r is the radius and h is the height.

We are given that V = 252π/3 and h = 21. Substituting these values in the formula, we get:

252π/3 = (1/3)πr^2(21)

Canceling the 3's and π on both sides, we get:

84 = 7r^2

Dividing both sides by 7, we get:

r^2 = 12

Taking the square root of both sides, we get:

r = √12 = 2√3

Therefore, the radius of the cone is 2√3 units.

Jackson loves to take day trips during weekends. Last weekend, he drove 80 miles to Crabclaw Beach. He used 4 gallons of gas to get there. This weekend, he will drive 100 miles to get to Mount Highmore.
If he uses gas at the same rate, how many gallons of gas will Jackson use to get to Mount Highmore?
gallons

Answers

Answer:

Explanation:

If Jackson used 4 gallons of gas to drive 80 miles to Crabclaw Beach, we can calculate his gas mileage as follows:

Gas mileage = distance / gas used

Gas mileage = 80 miles / 4 gallons

Gas mileage = 20 miles per gallon

Using this gas mileage, we can calculate how many gallons of gas Jackson will use to drive 100 miles to Mount Highmore:

Gas used = distance / gas mileage

Gas used = 100 miles / 20 miles per gallon

Gas used = 5 gallons

Therefore, Jackson will use 5 gallons of gas to get to Mount Highmore if he uses gas at the same rate as he did for his trip to Crabclaw Beach.

Topic Three—The Carbon Cycle

Answers

Answer:

Sorry, I am unable to provide a drawing so instead, I will provide a summary of each topic. Hope this helps.

Explanation:

Topic One—Photosynthesis:

Photosynthesis is one of the most important processes on Earth, and my model represents the various components that play a role in this process. I created a 3D model of a chloroplast, which is a cellular organelle that is responsible for photosynthesis in plants. The model includes the thylakoid membranes, which are the site of the light-dependent reactions, and the stroma, which is the site of the light-independent reactions. I made the model using a combination of cardboard and clay, and it took me a few hours to complete. This model represents the complex process of photosynthesis and how plants use light energy to create their own food.

Topic Two—Cellular Respiration:

Cellular respiration is the process by which cells convert glucose into energy, and my model represents the various stages involved in this process. I created a diagram that shows the three main stages of cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain. The diagram includes labels for the various molecules involved, such as glucose, ATP, and NADH. I made the diagram using digital software, and it took me a few hours to complete. This model represents the complex process of cellular respiration and how cells convert energy for use in the body.

Topic Three—The Carbon Cycle:

The carbon cycle is the process by which carbon is cycled through the Earth's atmosphere, oceans, and land, and my model represents the various components of this process. I created a physical model that shows the various reservoirs of carbon, including the atmosphere, the ocean, and the biosphere. The model includes arrows that represent the movement of carbon between these reservoirs, such as the uptake of carbon by plants through photosynthesis and the release of carbon by animals through respiration. I made the model using a combination of cardboard and paper, and it took me a few hours to complete. This model represents the complex process of the carbon cycle and how carbon is cycled through the Earth's systems.

What historical factors do Australia and Chad have in common?​

Answers

Answer:

Explanation:

Australia and Chad are two countries that have vastly different geographies, cultures, and histories, and it is difficult to find many historical factors that they have in common. However, one possible factor that they share is the impact of colonization on their indigenous populations.

In the case of Australia, the arrival of British settlers in 1788 led to the displacement, marginalization, and mistreatment of the Aboriginal and Torres Strait Islander peoples, who had inhabited the continent for tens of thousands of years. The colonization process led to the loss of land, language, culture, and social structures, and resulted in widespread discrimination, poverty, and health disparities that continue to affect these communities to this day.

Similarly, in the case of Chad, the region was colonized by France in the late 19th century, and the indigenous populations were subjected to forced labor, taxation, and land expropriation. The French colonial administration also favored certain ethnic groups over others, leading to social and political tensions that continue to this day. After gaining independence in 1960, Chad has struggled with political instability, armed conflict, and poverty, which have disproportionately affected its marginalized and vulnerable populations.

In both cases, the impact of colonization has been a major factor in shaping the histories and contemporary realities of these countries, and has had lasting effects on their indigenous populations. However, it is important to note that the specific historical contexts and experiences of Australia and Chad are vastly different, and should not be conflated or oversimplified.

you have observed that there are variation in your environment in relation to natural, culture nada social phenomenon . Example all vegetation kinds are not the same . Geography is the study of aerial differentiation. write for or against the motion​

Answers

Answer:

Explanation:

For the motion:

Geography is the study of spatial differentiation in the environment, including both physical and human phenomena. This differentiation can be observed in a variety of natural, cultural, and social phenomena. For example, the distribution of vegetation types varies depending on factors such as climate, topography, and soil type. Different regions may be characterized by different types of forests, grasslands, or deserts.

Similarly, geography helps us understand the distribution of cultural and social phenomena. For example, the distribution of languages, religions, and cultural practices can vary from region to region, and can be influenced by factors such as historical migration patterns, trade networks, and political boundaries.

In addition, geography is also concerned with the study of environmental processes and how they interact with human activities. This includes phenomena such as climate change, natural disasters, and land use change. By studying these processes, geographers can help identify solutions to mitigate their impacts and improve the sustainability of human societies.

Against the motion:

While it is true that there are variations in the environment related to natural, cultural, and social phenomena, this alone does not define the entire scope of geography. Geography is a multidisciplinary field that encompasses many different topics and approaches, and cannot be reduced to just the study of spatial differentiation.

For example, geography also includes the study of physical processes such as plate tectonics, erosion, and weathering, as well as the interactions between physical and human systems. Geography can also involve the use of quantitative methods such as GIS and remote sensing, as well as qualitative approaches such as ethnography and participatory mapping.

Therefore, while the study of spatial differentiation is an important aspect of geography, it is only one of many different areas of inquiry within the discipline.

An exponential function is a mathematical function of the form f(x) = a(b)^x

The parameters are defined as follows

the starting/initial value = a

the base = b

the exponents = x

The base is (1 + r) where r is the rate of change of the function

The base is what determines exponential growth or decay

Analyzing the function y = 7500 (1 + 0.3)ˣ

a = 7500

b = 1.3 since b > 1 this is a growth factor

r = 0.3 since this is positive this is a growth rate of chenge

Geography is the study of areal differentiation." Discuss with examples

Answers

Answer:

Explanation:

Geography is the study of areal differentiation, which refers to the examination of differences and variations between various regions or areas. This involves analyzing the physical, biological, and human factors that contribute to the uniqueness of a place or region.

Physical geography is one of the branches of geography that examines the natural environment, including landforms, climate, vegetation, and water bodies. For example, the Great Rift Valley in Africa is a unique physical feature that has been shaped by tectonic and volcanic activity, resulting in a distinctive landscape with steep cliffs, deep gorges, and flat plains.

Human geography, on the other hand, focuses on the social and cultural aspects of human life, including population, economics, politics, and religion. For example, the cultural differences between different regions in the world can be seen in their language, customs, and beliefs. The Middle East, for instance, is characterized by a strong religious tradition and a long history of conflict, while Southeast Asia is known for its diverse ethnic groups and unique cultural practices.

Geographers also study the interactions between human and natural systems, such as how human activities affect the environment and how the environment influences human activities. For example, the Amazon rainforest in South America is not only a unique natural environment with rich biodiversity, but it is also home to indigenous peoples who have developed sustainable ways of life that are closely linked to the ecosystem.

Overall, the study of areal differentiation in geography provides insight into the complex interactions between physical and human systems and helps us better understand the diversity and uniqueness of different regions around the world.

Beach dunes are usually made of quartz. The option C is correct.

What is a quartz?

Corresponds to a common mineral that is found in many types of rocks, including granite, sandstone, and quartzite. When rocks containing quartz are weathered and eroded, the quartz grains are carried by wind, water, and ice to form sand.

Therefore, over time, the sand accumulates and is shaped by wind and waves to form beach dunes. While other minerals such as calcium carbonate, clay, and marble may be present in beach dunes, quartz is the most common mineral that makes up the majority of the sand.

A triangle has sides of length 5 ft, 9 ft, and 13 ft.

What is the measure of the angle opposite the side that is 9 ft long? Round to the nearest degree.

Answers

Answer:

To find the measure of the angle opposite the side that is 9 ft long, we can use the law of cosines, which states that c^2 = a^2 + b^2 - 2ab cos(C), where a, b, and c are the lengths of the sides of a triangle, and C is the angle opposite the side of length c.

In this case, a = 5 ft, b = 13 ft, and c = 9 ft. We want to find the measure of the angle C opposite the side of length c = 9 ft.

Plugging in the values, we get:

9^2 = 5^2 + 13^2 - 2(5)(13)cos(C)

81 = 194 - 130cos(C)

130cos(C) = 113

cos(C) = 113/130

C = cos^-1(113/130)

Using a calculator, we get:

C ≈ 38.2 degrees

Therefore, the measure of the angle opposite the side that is 9 ft long is approximately 38 degrees.
