Answer:

9.49 units at an angle of 71.6° with the horizontal

Step-by-step explanation:

Magnitude: [x^2 + y^2]^(1/2)

(3^2 + 9^2)^(1/2)

(90)^(1/2) = 3root(10) = 9.49

Direction:

Angle with the horizontal: tan inverse (y/x)

tan inverse of (9/3)

tan inverse of 3 = 71.6°

1600 children and 1400 adults attended

<h3>How to determine the number of adults?</h3>

Let the children be x and adult be y.

So, we have the following equations:

x + y = 3000

1.5x + 5y = 9400

Make x the subject in x + y = 3000

x = 3000 - y

Substitute x = 3000 - y  in 1.5x + 5y = 9400

1.5(3000 - y) + 5y = 9400

Expand

4500 - 1.5y + 5y = 9400

Evaluate the like terms

3.5y = 4900

Divide both sides by 3.5

y = 1400

Substitute y = 1400 in x = 3000 - y

x = 3000 - 1400

Evaluate

x = 1600

Hence, 1600 children and 1400 adults attended
