<u>Answer:</u>
The correct answer option is B. 72°.
<u>Step-by-step explanation:</u>
A polygon is said to be a regular polygon when all its sides and angles are equal.
So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.
When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.
Therefore, option B is the right choice.
A mixed fraction... is made out of a whole number and a fraction. 3 7/10
Answer:
495
Step-by-step explanation:
pete=178
sharon=178+119=297
297+178=495
Answer: 18
Step-by-step explanation: If there were 18 seats in the row, it would be an even amount in each row, the same amount in each row, and would see everybody.
We first write the fractions in their decimal forms and find out the ratio.
2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33
Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1
Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds
Quantity of gravel sold will be 172 -108. 2 = 63 .8 pounds
