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:
∠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

Answers
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.

of highlands and
lowlands in Nigeria.
Answers
Answer:
The term "Lowlands" mainly refers to the Central Lowlands. However, in normal usage it refers to those parts of Scotland not in the Highlands (or Gàidhealtachd). The boundary is usually considered to be a line between Stonehaven and Helensburgh (on the Firth of Clyde).The Lowlands cover roughly the latter two.
The highlands provide many ecosystem services for the rest of the State, which is why it is so vitally important that we work hard to preserve the land. Ecosystem services are those intangible functions that ecosystems provide, a whole greater than the sum of its part.
The more fertile lowlands offer much better opportunities for arable and pastoral farming than the highlands - this creates jobs and helps boost the local economy.
disadvantages of lowlands are that the chances of flood is higher in plains, in plain disasters like twisters is common without mountains to prevent such disasters from happening, disasters are more in plain area than any other area, soil erosion may occur mainly in plain region, in plain population is the highest which result in more pollution.
The disadvantages of the highlands is that the mountain is a physical barrier to both communication and transport network, mountain is the cause of rain shadow effect, which may moderate dry climate after some time, mountain can erupt if it's volcano and cause lose of fauna and flora species on the place.
Which factor determines, or which factors determine, the density of ocean water? temperature salinity temperature, salinity, and light penetration temperature and salinity
Answers
Answer
Temperature and Salinity
Explanation:
The two key factors that determine the density of ocean water are the temperature of the water as well as the salinity of the water.
Theoretically the density of ocean water at the sea surface is usually about 1027 kg/m3. When the temperature is low then the density of ocean water increases until freezing of the water occurs.When there is also increase in Salinity if water the density of water also increases. However the temperature of an ocean have more impact on the density than the salinity of the ocean.
Density of ocean is usually calculated through the situ measurements of temperature, salinity by taking the sample of the ocean and taking it to laboratory

why does most communities have only about three or four trophic levels
Answers
Answer:
read below
Explanation:
As you progress through each trophic, each organism on that level loses energy gained from the previous trophic. This is due to losing energy through wasted material (e.g. bones) and to life processes, 7 of which can be remembered by MRS GREN:
M ovement
R espiration
S ensitivity
G rowth
R eproduction
E xcretion

This means that each time, energy is wasted and lost from the food chain. More than four trophics would result in so much energy being lost from the initial trophic (producer), that it would be largely pointless!

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.

Answers
Answer:
the answer is c
Explanation:
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.
