You would not be able to create a tessellation with an octagon right?

Mathematics

Ede4ka [16]3 years ago

Yes you are correct. An octagon cannot tessellate the plane. The reason why is because the interior angle is 135 degrees which is not a factor of 360. Trying to line up the angles will have overlap of the polygons. A tessellation happens when there are no gaps or overlaps of the polygons (think of a tile floor).

Contrast this with a regular hexagon which has an interior angle of 120 degrees, or an equilateral triangle with an interior angle of 60 degrees. Both 120 and 60 are factors of 360, so this shows that a regular hexagon and an equilateral triangle can be used to tessellate the plane.

Explain the error Tina says that 6:8 is equivalent to 36:64 what did tina do wrong
brilliants [131]
Tina said that 6:8 is equal to 36:64.
It's wrong. It should be 48:64. Because just like a fraction, whatever you multiply in the bottom, you do to the top.

Determine the first four terms of the sequence in which the nth term is...
Anon25 [30]

Answer:

1/5, 1/6, 1/7, 1/8

Step-by-step explanation:

The formula for the sequence is (n+3)!/ (n+4)!

The first terms uses n=1

a1 = (1+3)!/ (1+4)! = 4!/5! = (4*3*2*1)/(5*4*3*2*1) = 1/5


The first terms uses n=2

a2 = (2+3)!/ (2+4)! = 5!/6! = (5*4*3*2*1)/(6*5*4*3*2*1) = 1/6


The first terms uses n=3

a3 = (3+3)!/ (3+4)! = 6!/7! = (6*5*4*3*2*1)/(7*6*5*4*3*2*1) = 1/7


The first terms uses n=4

a4 = (4+3)!/ (4+4)! = 7!/8! = (7*6*5*4*3*2*1)/(8*7*6*5*4*3*2*1) = 1/8
