The angle of rotation of a polygon is found using the formula 360/n
Where n is the number of sides.
Shape 1: 360 / 10 = 36
Shape 2: 360 /4 = 90
Shape 3: 360 /5 = 72
Shape 4: 360/8 = 45
Shape 5: 360/3 = 120
Shape 6: circles = 1
Shape 7: 360 /6 = 60
Shape 8: 360 / 12 = 30
There are 3 shapes that are 72 or higher.
Answer:
The slope of the line is 1/2x
Step-by-step explanation:
Car normally has 4 wheeles
motorcycles normall have 2 wheels
c=cars
m=motorcycles
4c+2m=98
c+m=30
multiply second equation by -2 and add to the original equaiton
-2c-2m=-60
4c+2m=98 +
2c+0m=38
2c=38
divide 2
c=19
sub
c+m=30
19+m=30
m=11
11 motorcycles
19 cars
Answer:
x=900
Step-by-step explanation:
100-10=90
90/100=0.9
x*0.9=810
x=810/0.9
<em>x=900:)</em>
hope it helps!!
Have a great day
