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.
To simplify √((2x)^2)√2y, we
must multiply the indices of both roots and the coefficients that within both roots. As we can see bellow, we get a root which has index 4:
=((2x)^(2y))^1/4
Finally, the factor (2x)^2 has an exponent which is divisible by the index of the root, so it can be simplified, as it's shown in the following step:
=
(2x)(2y)^1/4
Step-by-step explanation:
1) 
We know that, 
2) 
Again using above property,
3) 
We know that,
So,
4) 
Hence, this is the required solution.
Answer:
The tip would be $5.40.
Step-by-step explanation:
Okay so we know the total is $36.00 which makes it easier. 15% of 36 is 5.4. So he would leave $5.40 as a tip.
The answer is 2m.
26 and 22 share a factor which is 2
