Highwall mining is often used when excavating an open-pit mine becomes too expensive. There are many advantages over underground mining, including the fact that it is both more cost-effective and involves less lead time.
An example of unit 10 study guide circles geometry is solve for x in the diagram attached.
<h3>What is Geometry?</h3>
This is known to be an aspect of mathematics that deals with the study of different sizes, shapes, positions angles etc.
To find x. bring like terms together.
6x + 33+ 45 = 180
6x + 78 = 180
6x = 180- 78
6x=102
x = 102/6
Therefore x = 17

Radiometric dating should be what they use
The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust.
Answer:
<em>Thermosphere</em>
Explanation:
<em>The </em>thermosphere<em> is one of the different layer of the atmosphere from all the other layers of atmosphere.</em>
<em>As thermosphere does not consist of mix gases, and it only consist of one gas. It is on the up of mesosphere and it remains down of the exosphere. And ultraviolet radiation are also caused in this particular layer of the amosphere of the earth.</em>
