There are three outcomes of 4 out of eighteen outcomes, so the fraction of angle of spinner numbered 4 is
To tessellate a surface using a regular polygon, the interior angle must be a sub-multiple (i.e. factor) of 360 degrees to cover completely the surface.
For a regular three-sided polygon, the interior angle is (180-360/3)=60 °
Since 6*60=360, so a regular three-sided polygon (equilateral triangle) tessellates.
For a regular four-sided polygon, the interior angle is (180-360/4)=90 °
Since 4*90=360, so a regular four-sided polygon (square) tessellates.
For a regular five-sided polygon, the interior angle is (180-360/5)=108 °
Since 360/108=3.33... (not an integer), so a regular five-sided polygon (pentagon) does NOT tessellate.
For a regular six-sided polygon, the interior angle is (180-360/6)=120 °
Since 3*120=360, so a regular six-sided polygon (hexagon) tessellates.
Answer:
290 inches
Step-by-step explanation:
Answer:
Approximately 23 cups of coffee
Step-by-step explanation:
Break even = Fixed cost/Selling price - variable cost
Fixed cost = $75
Selling price = $4.50
Variable cost = $1.25
Break even = $75/$4.50 - $1.25
= 23.076923077
Approximately = 23
Therefore, Mary has to sell approximately 23 cups of coffee daily in order to break evem
The right chose is -9x+3= the others are not hope this helped
