Explain how to find the central angle of a circle?

1 answer:

7 0

Given two points A and B, lines from them to center of the circle form the central angle∠AOB. The central angle is the smaller of the two at the center. It does not mean the reflex angle ∠AOB. As you drag the points above, the angle will change to reflect this as it increases through 180°.
Identify the inscribed angle and central angle subtended by the same arc. Recognize that the central angle is twice the measure of the inscribed angle subtended by the same arc. Identify the tangent(s) to acircle. Identify the point of tangency on a circle

Answer:

He used 6 bananas at .50 which cost $3.00

12 oranges at .75 which cost $9.00 and

3 papayas at $1.25 which cost $3.75

Step-by-step explanation:

We can set up a system of equations using the information given.

b for banana, r for orange, p for papaya

b + r + p = 21. Also given r = 2b So substitute to simplify for calculating two unknowns:

b + 2b + p = 21 The number of items.

50b + 75(2b) +125p = 1575 The cost.

I multiplied everything by 100 to eliminate the decimals.

To solve by substituion, rewrite the first equation to get a value for p in terms of b

p = 21 - 3b

Substitute this value in the second equation and solve for b.

50b + 150b + 125(21–3b) = 1575

200b +2625 –375b = 1575 Subtract 2625 from both sides and combine the like terms:

–175b = 1575 –2625

–175b = –1050. Divide both sides by –175

b = 6

Substitute in the original equation to find the amount of each fruit:

b + r + p = 21

b = 6 bananas

r = 2b. 2(6) = 12 oranges. I used r so as not to mix up o with 0.

6 + 12 + p = 21

p = 21 –18

p = 3 papayas

of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed o

Ksivusya [100]

Answer:

The answer here is 3/25, more left handed students.

Step-by-step explanation:

12/100 are left handed, which reduces to 3/25. This means that there are only 3 left handed kids for every 22 right handed kids, showing that there are more right handed students than left handed.
