Euler's Formula states that:
where V is the number of Vertices, E is the number of Edges and F is the number of Faces. We have also been given that the number of vertices is 15 and the number of Edges is 24 . We have been asked to find the number of Faces, F.
The Euler's formula can be rearranged to to isolate F as:
Substituting the values we get:
Thus, option C is the correct option.
Answer:
When the two values are different
Step-by-step explanation:
Like in an inequality equation.
For example:
The answer would be anything greate than or equal to 30, but you would need to find x. The number line would be very useful
Hope this helps
Answer:
x=17
Step-by-step explanation:
well the triangles are congruent so that equation has to equal 61, so set it equal to 61, once you do that subtract 10 with 61 giving you 51, then divide 3 with 51 and you get 17
Answer:
Area of red band is
Step-by-step explanation:
We know that area of square =
Please refer to the attached figure, we have to calculate the area of red band.
Required area = Area of square <em>ABCD </em>- Area of <em>purple square </em>
Side of purple square =
So, area of purple square =
<em>ABCD </em>is a square with purple square at the center and there is symmetry in the figure.
So, width of red band towards both the end is 5 inches.
Required area =
Using formula
Hence, Area of red band is
