Answer:
Step-by-step explanation:
The octahedron is formed from 2 congruent square pyramids.
Since each die has the shape of an octahedron, we would determine its volume by applying the formula for determining the volume of an octahedron which is expressed as
Volume = (a³√2)/3
Where
a represents the length of each edge.
From the information given,
a = 1 cm
Therefore,
Volume = (1³√2)/3 = 0.471 cm³
EF and BC in the trapezoid below are parallel. if ED=35, BC=63, and DC=28
Find the length of BD if EF = 45. Not all figures are rendered to scale.
A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
The base angles and the diagonals of an isosceles trapezoid are equal. The intersection point of the diagonals is collinear to the midpoints of the two opposite sides. Opposite sides of an isosceles trapezoid are of the same length or congruent to each other.

Answer: 
Step-by-step explanation:
1. Multiply by <em>y</em> both sides of the equation, as following:

2. Now you must multiply by 33 both sides of the equation, as following:

3. Now you must divide both sides of the equation by 9. Therefore, you obtain:
