The border of a susan b. Anthony dollar is in the shape of a regular polygon. How many sides does the polygon have what is the measure of each angle of the border round your answer to the nearest degree

Answers

Answer 1

Answer:

The polygon has 12 sides and each angle has a measure of 30°.

The border of a Susan B. Anthony dollar is in the shape of a regular polygon. A regular polygon is a polygon with equal sides and equal angles. To calculate the number of sides and measure of the angles, the formula for finding the measure of the interior angles of a regular polygon is used. The formula is (n-2)180/n where n is the number of sides. For the Susan B. Anthony dollar, the number of sides is 12, so the measure of the interior angles is (12-2)180/12 = 30°. Therefore, the polygon has 12 sides and each angle has a measure of 30°, rounded to the nearest degree.

D because there’s a pattern. Pattern for x is that it’s adding by one. Pattern for y is that it’s adding by 15

Answer:

Step-by-step explanation:

To tell if it is linear, we have to see if when x increases by 1, if y increases by a constrant rate.

The first one is not bbecause it goes 0, 1, 0, 3

Not B

It is D! This is because it increases by the same amount each time. 5 10 15 20

Answer: 3 laps

Step-by-step explanation:

To find out how many laps Andre swims per minute, we divide 12 by 4.

12/4 = 3

solve using the substitution and elimination method

3a-12b=9

4a-5b=3

can someone please help?

Answers

3a-12b=9 => a = 4b + 3; but, 4a-5b=3 => 4(4b + 3) -5b = 3 => 11b = -9 => b = -9/11 => a = -36/11 + 3 = -3/11;
