Answer:
Number of sides are 12.
Step-by-step explanation:
Given that smallest angle of rotational symmetry for a regular polygon is 30°.
we have to find the number of sides does the regular polygon have.
If we can rotate a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has the rotation symmetry.
Now as at the centre the angle is 360 and all the angles at the centre formed equal i.e
Hence, 12 number of sides the polygon have.
Answer:
The cost of 10 balls is
Step-by-step explanation:
Let
n -----> the number of balls used
P ----> the total price in dollars
we have
This is a linear equation in slope intercept form
where
the slope is
----> the coordinate y of y-intercept
To find out the cost of 10 balls, substitute the value of n=10 in the linear equation and solve for P
so
For n=10
The sum of 0.423 and 4.7 is 5.123
