Step-by-step explanation:
Answer:
D.) It has rotational symmetry with an angle of rotation of 90 degrees.
Step-by-step explanation:
i) the shape shown in the figure has reflectional symmetry with four lines of symmetry. There are four lines of symmetry such that each line when drawn divides the shape into two exact halves such that if each half were too be folded across the line of symmetry it would produce the other half exactly.
Therefore Option A.) and Option B.) are not true
ii) It has point symmetry which means if the shape is rotated by 180 degrees the shape does not change. Therefore Option C.) is not true.
iii) the shape has rotational symmetry because if the shape is rotated though any between 0 degrees and 360 degrees the shape appears to be unchanged.
Therefore the correct options are
D.) It has rotational symmetry with an angle of rotation of 90 degrees.
Answer:
B
Step-by-step explanation:
Out of the 4 options, we only need 1. Therefore, the probability is 
Answer:
Step-by-step explanation:
Note that 20 (an approximation for 205) less 4 (an approx. for 431) comes out to 16.
This tells us that the proper placement of the decimals is
20.50
- 4.31
----------
and this comes out to 16.19.
