Answer:

40% students play the saxophone.

Step-by-step explanation:

Given:

Total Number of students who play woodwind instrument = 45

Number of students who play saxophone = 18

We need to find the percent of students who play saxophone.

Solution:

Now we can say that;

To find the percent of students who play saxophone we will divide Number of students who play saxophone by Total Number of students who play woodwind instrument and the multiply by 100.

framing in equation form we get;

percent of students who play saxophone = \frac{18}{45}\times100= 40\%

Hence 40% students play the saxophone.

sammy [17]

Answer:

The amount of interest is $5580.            

Step-by-step explanation:

Given : Jacob borrowed $30, 000 to start up his consulting business. The loan had simple interest rate of 6.2% for 3 years.

To find : The amount of interest he will pay with the loan ?

Solution :

Using interest formula,

I=P\times R\times T

Where, P is the principal P=$30,000

R is the rate of interest R=6.2%=0.062

T is the time t=3 years.

Substitute the value in the formula,

I=30000\times 0.062\times 3

I=5580

Therefore, The amount of interest is $5580.

Find all solutions to the equation. 2sin theta - squareroot 3 = 0
Xelga [282]

Answer:

\theta =2mπ + π/3 for m ∈ Z.

Step-by-step explanation:

Given the equation 2sin\theta - \sqrt{3} = 0, we are to find all the values of \theta that satisfies the equation.

2sin\theta - \sqrt{3} = 0\\\\2sin\theta = \sqrt{3} \\\\sin\theta = \sqrt{3}/2 \\\\\theta = sin{-1} \sqrt{3}/2 \\\\\theta = 60^0

General solution for sin\theta is \theta = nπ + (-1)ⁿ ∝, where n ∈ Z.

If n is an even number say 2m, then \theta = (2m)π + ∝ where ∝ = 60° = π/3

Hence, the general solution to the equation will be \theta = 2mπ + π/3 for m ∈ Z.
