in a choir the ratio of men to woman is 4:7. 25% of the men prefer classical songs, and 80% of the women prefer classical songs. What percentage of the choir prefer classical songs?

Answers

Answer:

60%

Step-by-step explanation:

percentage of men in the choir = (4/11) x 100 = 36.4%

percentage of women in the choir = (7/11) x 100 = 63.6%

Percentage of men in the choir that prefer classical songs = 36.4 x0.25 = 9.1%

Percentage of women in the choir that prefer classical songs = 0.8 x 63.6% = 50.9%

percentage of the choir prefer classical songs = 50.9% + 9.1% = 60%

Answer:

3.14 units

Step-by-step explanation:

The formula for the length of an arc is ...

s = rθ

where r is the radius of the circle, and θ is the central angle in radians.

The relationship between degrees and radians is ...

180° = π radians

If we divide this equation by 3, we see ...

60° = π/3 radians

The radius is given as 3 units, so the arc length is ...

s = (3 units)(π/3) = π units

The arc length is 3.14 units.

15% of a number is 30. What is the number?
A)4.5
B)20
C)45
D)200

Answers

15% of 200 is 30

so the answer would be D

The answer is D, 200.

Since the total percentage is 100, you would divide that by 15.

100/15=6.666...7

Then, you would multiply that by 30

6.6666...7*30=200

Answer:

m∠BAC = 52° or theta = 52°

Step-by-step explanation:

I am guessing that you are trying to find m∠BAC ( which is theta)

(1) The measure of an inscribed angle is 1/2 the measure of the intercepted arc

measure of arc BC is twice the measure of ∠CDB

measure of arc BC = 2(26) = 52

(2) The measure of a central angle equals the measure of the intercepted arc.

m∠BAC = 52°

Note: You need to remember statements (1) and (2) to help you with this type of problem. OK?
