Answer:

21feet = h

The height of the pyramid is 21 feet

Explanation:

Like the volume of any pyramid and any tetrahedron, the volume is the area of the base by the height and divided by three.

a and b are the sides of the base, which is a rectangle, and therefore a*b is the area of the base.

Volume= a*b*h/3

1) The term we need to know is the h which is the height. What we are going to do is to leave alone the h in one side of the equation applying math properties.

3*V= a*b*h

What we did was to bring the 3 to the other side. It was dividing on the right side of the equiation. To go to the other side, it must multiply the term on the left.

2) Now, we need to bring the a*b to the left side. We take the term and pass it dividing the term on the left.

(3*V )/ (a*b) = h

3) Now we can use the equation to find the height.

(3*525f³) / (15f*5f) = h

21f = h

Define 5exual orientation. What environmental factors have been ruled out as contributors to homo5exuality? What biological fact

tatuchka [14]

5exual orientation is the romantic or 5exual attraction to someone. There is so hard evidence that science has found that link environmental influences with homo5exuality but they have linked childhood gender nonconformity to homo5exuality. They think homo5exuality is a interplay of genetic hormonal influences.

8. What number does the density have to be less than for it to float in water? Write a

Masteriza [31]

Answer:

Answer: Compare the density of the object in question to the density of water. If its density is less than water, it will float. For example, oak floats because its density is 0.7 g/cm³. If the density of an object is greater than water, it will sink.
