Answer:

They have small crystals.

Explanation:

Extrusive igneous rocks form when lava reaches the Earth's surface a volcano and cools quickly. Most extrusive or volcanic rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian. Intrusive, or plutonic, igneous rocks form when magma cools slowly below the Earth's surface.

Tommy and Erin are building a skateboard ramp. They want the ramp to be 3 feet tall and 5 feet long.
BARSIC [14]

Answer:

Full question is attached.

Tommy's reasoning is wrong because the hypotenuse is not 5 feet.

A skateboard ramp resembles a right angles triangle so its sides resemble that of a right angled triangle.

The height of 3 feet would be the height of the triangle.

The length of 5 feet would be the length of the triangle.

The piece of plywood that would cover the top of the frame would be the hypotenuse.

In using the Pythagoras rule, the c is the hypotenuse but Tommy made the mistake of assuming that the hypotenuse was b which is where the error came from.

Instead of solving for b, they should have been solving for c which is the hypotenuse.

a² + b² = c²

3² + 5² = c²

9 + 25 = c²

c² = 34

c = √34

c = 5.83 feet

They should use a plywood of 5.83 feet not 4 feet.

The major industrial nations of the world, like the United States and China, are also the world's largest
Vinvika [58]

Answer:

This problem should be worked on by the most developed countries as they have the biggest capacity, and after they get on the right way to help the developing countries and show them the way as to how to do it as well.

Explanation:

The carbon emissions that humanity is releasing into the atmosphere can not be attributed to only a few countries, but to most of the countries in the world. All countries that have some kind of industry contribute to the problem, though some countries much more than others.

In order for carbon emissions to decrease there should be a global collaboration. The most developed countries because they have the most finances and resources should lead the way and come up with solutions, and once they do this to help the developing countries with it so that they can also stop the carbon emissions.

Many countries are already on the right path, namely Germany, the Netherlands, France, the Scandinavian countries. The two biggest economies though, the US and China don't even want to hear about this because of their race for economic dominance, so it seems that reasoning the governments of these two countries will be the most important step for global turnaround.
