Answers

Answer 1

Answer:

Only early Earth was intensely bombarded by large rocks and ice from space.

Explanation:

Primitive Earth was hit several times by meteors, meteorites, rocks and ice from space. The impact of these bombings was very intense and it modified the entire structure and resources of the earth, besides harming life in general. The extinction of the dinosaurs was a result of this bombardment, for example, but there were many mass extinctions whenever one of these elements hit the planet. Another result was the modification of environmental conditions, which were very different from what we know today.

However, most Americans do not notice much difference between the two countries, which share common borders and culture. ... Americans are generally more sociable, patriotic, conservative, religious, and traditional. Canadians are more restrained and at the same time more liberal

Canada is approximately 9,984,670 sq km, while United States is approximately 9,833,517 sq km, making United States 98.49% the size of Canada. Meanwhile, the population of Canada is ~37.7 million people (294.9 million more people live in United States).

If david's dad's room is rectangular with one side being 8.5 feet, and If David wants to buy a rug to cover half of his bedroom floor, what should the area of the rug be?

Answers

Answer:

Area of rug for half room = 4.25a feet²

Explanation:

Given:

One side of rectangular room = 8.5 feet

Find:

Area of rug for half room

Computation:

Assume;

Another side of rectangular room = a feet

So,

Area of rectangle = length x width

Area of rectangle room = 8.5 x a

Area of rectangle room = 8.5a feet²

Area of rug for half room = Area of rectangle room / 2

Area of rug for half room = 8.5a / 2

Area of rug for half room = 4.25a feet²

identify the explicit function for the sequence in the table. x:1, 2, 3, 4, 5, y: 8, 14, 20, 26, 32,

Answers

Answer:

The explicit function is y = 6x + 2

Explanation:

Since the change in x, Δx is constant and Δx = 1 and also, the change in y, Δy is constant and Δy = 6, we use the equation of a straight line in gradient form.

So, (y - y₁)/(x - x₁) = Δy/Δx where x₁ = 1 and y₁ = 8

So, substituting the values of the variables into the equation, we have

(y - y₁)/(x - x₁) = Δy/Δx

(y - 8)/(x - 1) = 6/1

(y - 8)/(x - 1) = 6

cross-multiplying, we have

(y - 8) = 6(x - 1)

expanding the brackets, we have

y - 8 = 6x - 6

adding 8 to both sides of the equation, we have

y - 8 + 8 = 6x - 6 + 8

y + 0 = 6x + 2

y = 6x + 2

So, the explicit function is y = 6x + 2

Answer: ;) a(n) =8 + (n-1) •6

The Theory of Plate Tectonics explains how single mountain systems can stretch between continents, even though the ranges are separated by large oceans.

Answers

Answer:

TRUE

Explanation:

The theory of the plate tectonics states that solid outer crust of the Earth, known as the lithosphere, is separated out into the plates which moves over the asthenosphere, which is the mantle's upper portion that is molten. The oceanic plates and the continental plates, they come together, they spread apart, and interact at the boundaries all over the planet.

These plates move around on the earth's surface by the spreading of the seafloor. Thus when a single mountain system are stretched between the continents, they are separated by the large oceans which is explained by the Tectonics plate theory.

In August 2005, Hurricane Katrina wreaked havoc on the Gulf Coast. It was the costliest and one of the deadliest hurricanes in US history. Since that time, the simulations that meteorologists run to track and model hurricanes have significantly improved. With global climate change, scientists expect the hurricane season to become longer and the number of large storms to increase. However, they expect the advances in modeling to improve our ability to predict and prepare for storms in the future. Which are contributing factors to the improvements in modeling and simulation of hurricanes

Answers

Answer: Changes in available computing power as well as refinement of the software improve the ability to produce timely predictions of storm changes.

• Improvements in the quality of data collected on the ground, from airplanes, and from space have improved, allowing the level of detail in the models improve significantly.

Recall from Parts A and B that the difference in elevation between placemarks A and B was 120 meters and that the distance between the placemarks was 155 meters. Calculate the dip angle of the Fountain Formation in this area between placemarks A and B.

Answers

Answer:

37.75°

Explanation:

The distance between place marks A and B (AB) is 155 meters. The change in elevation (Δh) between A and B is 120 meters.

Dip is the angle at which a planar feature is inclined to the horizontal plane; The dip angle is always in a vertical plane and is measured downward from the horizontal plane, the dip is also perpendicular to the strike.

The dip angle of the Fountain Formation can be found by the following formula:

dip angle = tan⁻¹(change in elevation/distance) = tan⁻¹(Δh/d)

Substituting:

Dip angle = tan⁻¹(120/155) = 37.75°
