A minor arc is defined as an arc of a circle that consists of a measurement less than or equal to radians. The measure of a minor arc is always less than 180 degrees. When naming a minor arc, you should two letters on the circle. Major arcs and semicircles use three letters.

Answer:

If the arc length is less than 180 degrees, then it is called minor arc.

Minor arc length = m(AB), where "A" and "B" are the end points of the arc length.

Step-by-step explanation:

If you take two points on the circle and connect the points to the center of the the circle (radius). You will get the arc length subtend by the radi.

If the arc length is less than 180 degrees, then it is called minor arc.

If the arc length is greater than 180 degrees, then it is called major arc.

Minor arc is shortest arc length and major arc is the longest arc length.

The arc length marked with the endpoints of the arc length.

If you name the two points A and B of the minor arc.

The measure of the minor arc length represented by m(AB)

Herewith I have attached the figure.

Bill and Mary Ann went to the Viola bakery. Bill bought 5 pies and 7 donuts for $12.65. Mary Ann bought 6 of each for $12.30.

Answer:

Pies=$0.85

Donuts= $1.20

Step-by-step explanation:

In the equation let p stand for the number of pies and d stand for the number of donuts.

To solve this set up 2 equations, one representing bill and the other representing Mary Ann.

Bill's equation is 5p+7d=$12.65.
Mary Ann's equation is 6p+6d=$12.30

Then solve using a system of equations. Systems of equations can be solved using elimination or substitution. I will use substitution. Solve bill's equation for p. This gives you $p=\frac{12.65-7d}{5}$ . Then, you can substitute that into Mary Ann's equation. This looks like $6\cdot \frac{12.65-7d}{5}+6d=12.3$ . Solve for d. Once you solve d=1.20. Finally, substitute 1.20 back into either Bill's or Mary Ann's for d and solve for p. No matter which equation you use p=0.85.
