Answer: 13 dimes and 7 quarters I think
Step-by-step explanation:
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.
3x+x=y
3(-3)+(-3)=y
-9-3=y
-12=y
Therefore the value of x3+x is -12

Step-by-step explanation:
A <u>central</u><u> tendency</u> is a value that describes the center of a data set and includes the mean, median, and mode.
And just in case you don't know:
Mean is the sum of all the numbers divided by how many numbers there are. Basically the average.
Mode is the number that occurs the most times.
Median is the middle number when you write the numbers from lowest to greatest.<u />
