The answer is 91.

The question is based on on a mathematical topic called ''Geometry'', and is simply asking for the total number of the oranges in the four-sided pyramid.

<h2>Further Explanation</h2>

In geometry, a pyramid is a polyhedron that is constructed when the polygonal base is connected to an iconic surface. The base edge and apex form a triangle that is called a lateral face. A pyramid can also be with an n-sided base that has n + 1 vertices, n + 1 faces, and 2n edges.

But the first thing to do is to get the number of oranges in each phases of the four-sided pyramid. To do this, we square the root the numbers of the vertices.

1 squared = 1 [for the first phase of the pyramid]

2 squared   =4 [we got 4 as our answer for the second layer of the pyramid]

3 squared = 9 [9, for the third phase of pyramid]

4 squared = 16  

5 squared = 25  

6 squared = 36 [and 36 is the last in the pyramid]

The addition of the total oranges in each phase of the six layers is 91.

The total number of oranges in the pile = 1+4+9+16+25+36=91

Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25 
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
                                                               = 91 oranges

The example of a biotic factor is the shrimp population in a bay. Biotic factors are living factors that affect organisms in an ecosystem. The biotic factors includes the producers or autotrophs, consumers or heterotrophs, and decomposer. Abiotic factors on the other hand are the non-living factors that influence an ecosystem; they include, sunlight, soil, humidity, etc

The moon causes the earths Rotation to speed up / slow down which ?
My name is Ann [436]

Answer: slow down

Explanation:As Earth rotates, the Moon's gravity causes the oceans to seem to rise and fall. (The Sun also does this, but not as much.) There is a little bit of friction between the tides and the turning Earth, causing the rotation to slow down just a little. As Earth slows, it lets the Moon creep away.
