I will use this notation m arc AB to name the measure of the arc AC in degress, going from A to B counterclock wise.

Also, note that the measure of an arc is equal to the measure of the central angle from which the arc is generated.

With that:

1) m arc AB

m arc AB is equal to the angle AOC

The angle AOC is indicated to be 49°, so m arc AB is also 49°.

Answser: 49°

2) m arc ABC

m arc ABC is equal to 360° - angle COA = 360° - 107° = 253°

3) m arc BAC

m arc BAC is equal to angle AOB + angle COA

m arc BAC = 49° + 107° = 156°

Answer: 156°

4) m arc ACB

m arc ACB = 360 ° - angle AOB = 360° - 49° = 311°

Answer: 311°

Fred sold 14 rolls of wrapping paper for a band fundraiser earning the band $17.50. Sharon sold 16 rolls of wrapping paper and e
steposvetlana [31]

Answer: 1.25 dollars per roll


Step-by-step explanation:

If  the relationship is graphed with the number of rolls sold on the x-axis and the money earned on the y-axis

Then the two points on that line will be (14,17.50) and (16,20)

We know that the slope of a lien with points (x_1,y_1)\ and\ (x_2,y_2) is give by:-

Slope=\frac{y_2-y_1}{x_2-x_1}

Hence, the slope of the graph with points  (14,17.50) and (16,20) is given by :-

Slope=\frac{20-17.50}{16-14}=\frac{2.50}{2}=1.25

Therefore, the slope of the graph = 1.25 dollars per roll.

Y=x²-4x+6<br> y=x+2<br><br><br> Please help
Ira Lisetskai [31]

Answer:

(1, 3), (2, 4).

Step-by-step explanation:

y= x² - 4x + 6

y = x + 2

Substitute for y in the first equation:

x + 2 = x²- 4x + 6

x^2 - 5x + 4 = 0

(x - 1)(x - 4) = 0

x = 1, 4

When x = 1 , y = 1 + 2 = 3.

When x = 4, y = 4 + 2 = 6.

A pennant is a shape of a triangle has a base of 12 inches and a height of 30 inches. What the area of the pennant?
Korolek [52]

Answer:

180 square inches

Step-by-step explanation:

Area, A is given by A=0.5bh where b is base and h is height. Since both of these dimensions are provided then we substitute the given figures into the formula. Substituting 12 inches for base, b and 30 inches for height, h then the area will be equivalent to

A=0.5*12*30=180 square inches.

Therefore, the area of the described triangle is 180 square inches.
