Answer:

(h+c)/ch ÷ (h²+c²)/c²h²

(h+c)/ch × c²h²/(h²+c²)

(h+c)/1 × ch/(h²+c²)

ch(h+c)/(h²+c²)

I would appreciate if my answer is chosen as a brainliest answer

Stells [14]
If a1 is the first term of an arithmetic sequence and d is the common difference, then the formula for finding thenthtermofthesequenceisan =a1+(n−1)d.
Wehavebeengivena1 =5andd=15. We’reaskedtofindn=40.
an =a1 +(n−1)d a40 = 5+(40−1)·15
= 5+39·15 = 590

The volume of a pyramid that fits exactly inside a cube is 18 cubic feet. what is the volume of the cube? 6 cubic feet 18 cubic
fomenos

The volume of the cube that perfectly fits an 18 ft³ pyramid is calculated as (C) 54 ft³.

<h3>What is a cube?</h3>
  • A cube is a three-dimensional solid object with six square faces, facets, or sides, three of which meet at each vertex.
  • The cube is one of the five Platonic solids and the only regular hexahedron.
  • It has six faces, twelve edges, and eight vertices.

To find the volume of the cube that perfectly fits an 18 ft³ pyramid:

We have been provided that:

  • 18 cubic feet is the volume of the pyramid.
  • Now, in order for this pyramid to fit exactly into a cube, the base of the pyramid must be square, and the height of the pyramid must be equal to the height of the cube.
  • We can conclude from this that the volume of a cube equals three times the volume of a pyramid.
  • So, the volume of the cube = 3 × 18
  • The volume of Cube = 54 ft³

Therefore, the volume of the cube that perfectly fits an 18 ft³ pyramid is calculated as (C) 54 ft³.
