In trapazoid abcd ab is parallel to dc, bc is perpendicular to dc determine the measure of d to the nearest degree and find the lemgth of ad in simplest radicial form

Answers

Answer 1

Answer:

∠d = 56.3°

AD = 3.6 inches

Explanation:

The trapezoid can be decompose to a rectangle and a triangle. The triangle has a hypotenuse AD, height of 3 inches and base of 2 inches (7 - 5)

[tex]tan(d)=\frac{opposite}{adjacent} =\frac{height}{base} \\tan(d)=\frac{3}{2} \\tan(d)=1.5\\d=tan^{-1}(1.5)=56.3^0[/tex]

Therefore, ∠d = 56.3°

Using Pythagorean theorem:

AD² = base² + height²

AD² = 3² + 2²

AD² = 9 + 4 = 13

AD = √13 = 3.6 inches

In Trapazoid Abcd Ab Is Parallel To Dc, Bc Is Perpendicular To Dc Determine The Measure Of D To The Nearest

List and describe at least four reasons why some countries are rich and some are poor. Long Explanation Required!

Answers

Answer:

Explanation:

In common language, the terms "rich" and "poor" are often used in a relative sense: A "poor" person has less income, wealth, goods, or services than a "rich" person. When considering nations, economists often use gross domestic product (GDP) per capita as an indicator of average economic well-being within a country. GDP is the total market value, expressed in dollars, of all final goods and services produced in an economy in a given year. In a sense, a country's GDP is like its yearly income. So, dividing a particular country's GDP by its population is an estimate of how much income, on average, the economy produces per person (per capita) per year. In other words, GDP per capita is a measure of a nation's standard of living. For example, in 2016, GDP per capita was $57,467 in the United States, $42,158 in Canada, $27,539 in South Korea, $8,123 in China, $1,513 in Ghana, and $455 in Liberia (Figure 1).

Because GDP per capita is simply GDP divided by the population, it is a measure of income as if it were divided equally among the population. In reality, there can be large differences in the incomes of people within a country. So, even in a country with relatively low GDP, some people will be better off than others. And, there are poor people in very wealthy countries. In 2013 (the most recent year comprehensive data on global poverty are available), 767 million people, or 10.7 percent of the world population, were estimated to be living below the international poverty line of $1.90 per person per day.3 Whether for people or nations, the key to escaping poverty lies in rising levels of income. For nations specifically, which measure wealth in terms of GDP, escaping poverty requires increasing the amount of output (per person) that their economy produces. In short, economic growth enables countries to escape poverty.

what is the impact of cobalt mining in the congo? write in as much detail as possible pls

Answers

In Congo’s sun-scorched and dusty south, thousands of miners scour underground tunnels hunting for cobalt. Many of them work by hand. That’s why they are known as creuseurs — French for diggers.
They don’t use power tools. They don’t wear face masks and often no gloves. They do it because they live in one of the poorest countries in the world, and cobalt is valuable. The mineral is essential for the lithium-ion batteries found in smartphones and many electric vehicles. Most of the world’s cobalt supply comes from the Congo region. These cobalt-laden chunks of rock leave the country destined for refineries in Europe and China, where they enter the complex supply chains of some of the largest technology and automotive firms.
Creuseurs know their work is physically dangerous. Death and injury from tunnel collapses are not uncommon. Children sometimes join their older brothers and fathers in the mines

Occasionally earthquakes occur as a result of collisions along oceanic-continental convergent boundaries. Where do these earthquakes most likely occur?

on land but close to oceans
inland, far from the coast
in the middle of the oceans
anywhere there are mountains

Answers

Answer:

 on land but close to oceans

Explanation:

A boundary between an oceanic plate and a continental plate will be near a coastline., not "far from the coast" or "in the middle of oceans."

Often, mountains are also near that boundary, but mountains may also exist elsewhere, so "anywhere there are mountains" is not an apt description.

The best choice is "on land but close to oceans."

C. The Colorado River runs through the Grand Canyon.
D. The Continental Divide acts as a boundary that determines to which ocean rivers flow.

Answers

Answer:

A. The Grand Canyon was formed by the continuous flow of the Columbia River.

Explanation:

The Columbia River and the Grand Canyon do not have any touching point, let alone that the Grand Canyon has been formed by the flow of this river. Columbia River is a big river, and it flows through the northwestern part of the country. It is very important for the people that live in this part of the Untied States because the river flows into the Pacific Ocean, and it is big enough so that boats can move through it and go further in the mainland, so economically it is a very important feature in the region.

How does the greenhouse effect help regulate Earth's temperature compared to the Moon, even though they are similar distances from the sun?


Answers

Answer:

Explanation:

The greenhouse effect is a process where energy from the sun readily penetrates into the lower atmosphere and onto the surface of Earth and is converted to heat, but then cannot freely leave the planet. Due to the presence of certain greenhouse gases that trap heat, like carbon dioxide, methane, water vapor, and CFCs, the atmosphere retains the sun's radiation and warms up the planet.

moon does not have the ability to trap the sun's heat, so it is cool even if they are similar distances from sun

Despite promising signs that lack of human activity during times of lockdown had led to flourishing wildlife across the world, loss of income is causing some people to exploit the environment. Evaluate this statement.

Answers

Answer:

The statement is true, and represents a situation that has happened many times before.

Explanation:

First of all, the lockdown has only been strict, and for brief periods of time, in mostly developed countries. In the majority of developing countries, the lockdown has been more flexible, because a big part of the population cannot stay inside for more than a few days, since they have to leave their homes to work and make a living.

The fall in economic activity leads some people to overexploit the enviroment in order to compensate. For example, poor farmers may burn more forest to increase crop sizes, and fishermen may overfish in some areas.

To study "the world in spatial terms" means to study locations. The correct option is c.

In spatial terms, the world encompasses the placement of items in the world. While geography is more than just maps, it does take into account the location of places and how it affects the issue.

Absolute and relative location are notions in geography. Absolute location is one that does not alter, such as your longitude and latitude, whereas relative location is one that is relative to another, such as living between the Catholic church and the grocery.

Therefore it can be said that to study "the world in spatial terms" means to study locations.
