Answer:
Option (2) is the answer.
Step-by-step explanation:
From the figure attached,
AB represents the length of Mr. Ray, ED represents the light post and the mirror was placed at point C.
Here AB = d = 6 feet
CD = w = 32 feet
BC = f = 9 feet
Since both the triangles ABC and EDC are similar, their corresponding sides will be in the same ratio.
h = 
h = 21.33 feet
h ≈ 21.3 feet
Therefore, height of the light post is 21.3 feet.
Option (2) is the answer.
There are 3 girls & 4 boys.
Each student makes 8 paper airplanes.
Amount of paper airplanes created by girls: 3 x 8 = 24
Amount of paper airplanes created by boys: 4 x 8 = 32
Amount of paper airplanes created in all: 3(8) + 4(8) = 24 + 32 = 56

Answer:
y= 15
Step-by-step explanation:
Y= Kxz
y=6 x=1/2 z=6
15= K (1/2) (6)
15= K (3)
K= 5
SO
y= (5) (1/2) (6)
Y= 15
