Answer:

<u>Numerator:</u>

  • sin (A + B)  = sin A cos B + cos A sin B

<u>Divide by cos A cos B:</u>

  • sin A /cos A + sin B /cos B = tan A + tan B

<u>Denominator</u>:

  • sin (A - B)  = sin A cos B - cos A sin B

<u>Divide by cos A cos B:</u>

  • sin A /cos A - sin B /cos B = tan A - tan B

<u>Connect all bits together to get:</u>

  • sin(A + B) / sin(A - B) = (tan A + tan B) / (tan A - tan B)

A museum requires a minimum number of chaperones proportional to the number of students on a field trip. The museum requires a m
Stells [14]

Answer: See explanation

Step-by-step explanation:

Here is the complete question:

A museum requires a minimum number of chaperones proportional to the number of students on a field trip. The museum requires a minimum of 3 chaperones for a field trip with 24 students. Which of the following could be combinations of values for the students and the minimum number of chaperones the museum requires? Choose 2 answers.

A. Students: 72

Minimum of chaperones: 9

B. Students: 16

Minimum of chaperones: 2

C. Students: 60

Minimum of chaperones: 6

D. Students: 45

Minimum of chaperones: 5

E. Students: 40

Minimum of chaperones: 8

Since the museum requires a minimum of 3 chaperones for a field trip with 24 students. This means that there will be 24/3 = 8 students per chaperone.

We then divide the number of students given in the question by the number of chaperone to know our answers. This. Will be:

Students: 72

Minimum of chaperones: 9

This will be: 72/9 = 8

Therefore, this is correct.

B. Students: 16

Minimum of chaperones: 2

This will be: 16/2 = 8

This is correct

C. Students: 60

Minimum of chaperones: 6

This will be: = 60/6 = 10.

Therefore, this is wrong

D. Students: 45

Minimum of chaperones: 5

This will be 45/5 = 9

Therefore, this is wrong.

E. Students: 40

Minimum of chaperones: 8

This will be: 40/5 = 8.

Therefore, this is wrong.

Therefore, options A and B are correct.

What is the volume of the prism. 4.1 2.8 5.1
Fed [463]
So, when finding the volume, we would just add up every side, and from the question above, it look like that the numbers that we would be adding are the following above.

4.1+ 2.8+ 5.1=(11.2)

The volume would be 11.2
