Answer:
The correct answer is 12 and a half or 13 weeks.
Step-by-step explanation:
First, convert the values to decimals.
27 1/2 = 27.5
2 1/4 = 2.25
Then, divide miles of road that need to be repaved by the number of miles that are repaved per week.
27.5/2.25 = 12.2222222222222
Round that up to 12 and a half weeks or 13 weeks.
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.
