In this question, We have to find which rotation about its center will carry a regular decagon onto itself?
A decagon : 10 sided polygon
As we know, a full rotation can be 360°.
For a decagon: 360/10 =36
For a decagon, any multiple of 36 can map onto itself.
In our options only 252 is the multiple of 36.
So, correct answer is option D252

7 times approximately 4.4 equals approximately 31 .
To find the number that, when multiplied by 7, equals 31, we need to solve the equation :
7 * x = 31
Here, x represents the unknown number we are trying to find .
To isolate x, we divide both sides of the equation by 7 :
( 7x ) / 7 = 31 / 7
Simplifying, we have :
x = 31 / 7
Calculating the division, we find :
x ≈ 4.4285714
x = 4.4
7 * 4.4 = 31
Therefore, 7 times approximately 4.4 equals approximately 31 .
