In RSM camp, there are four counselors for every fifty seven students and three teachers for every five counselors.

Ray Of Light [21]

Answer:

Students : Counselors : Teachers = 285: 20 : 12

Step-by-step explanation:

In the camp, the ratio of:

( C: S ) Counselors : Students is 4 : 57

( T: C ) Teachers : Counselors is 3 : 5

To determine the ratio of - Students : Counselors : Teachers

Here given - C : S = 4 : 57

Multiplying both sides by 5, we get

C: S = 4 x 5 : 57 x 5 = 20 : 285

So, for every 20 counselors, there are 285 students ...... (1)

Similarly, given Teachers : Counselors is 3 : 5

Multiplying both sides by 4, we get

T : C = 3 x 4 : 5 x 4 = 12 : 20

So, for every 12 teachers, there are 20 Counselors ...... (2)

Hence, in both equation 1 and 2 the number of counselors is same = 20 .

Hence, both the ratios acne be combined.

So we get C : S = 20 : 285 and T : C = 12: 20

Inverting the values

⇒ S : C = 285 : 20 and C : T = 20 : 12

or, S : C : T = 285: 20 : 12

or, Students : Counselors : Teachers = 285: 20 : 12

Hence, for every 285 students there are 20 counselors and 12 teachers.

Trig Help please! 50 points!

IgorLugansk [536]

Answer:

Step-by-step explanation:

Remember the mnemonic: SohCahToa, where:

$\sin(\theta)=\text{opposite}/\text{hypotenuse}\\\cos(\theta)=\text{adjacent}/\text{hypotenuse}\\\tan(\theta)=\text{opposite}/\text{adjacent}$

Let's determine our side lengths first.

Note that our angle is A. So, we have to determine the sides with respect to A.

The opposite side to A is 16.

The adjacent side is 12.

And the hypotenuse is 20.

With this, we can find our trig ratios:

Sine:

$\sin(A)=\text{opp}/\text{hyp}$

Substitute 16 for the opposite and 20 for the hypotenuse. This yields:

$\sin(A)=16/20$

Reduce:

$\sin(A)=4/5$

Cosine:

$\cos(A)=\text{adj}/\text{hyp}$

Substitute 12 for the adjacent and 20 for the hypotenuse. This yields:

$\cos(A)=12/20$

Reduce:

$\cos(A)=3/5$

Tangent:

$\tan(A)=\text{opp}/\text{adj}$

Substitute 16 for the opposite and 12 for the adjacent. This yields:

$\tan(A)=16/12$

Reduce:

$\tan(A)=4/3$

So, our answers are:

$\frac{4}{5}, \frac{3}{5}, \text{ and } \frac{4}{3}$

Out of the answer choices, the choice that represents this is C.

So, our correct answer is C.

And we're done!
