Answer:
Step-by-step explanation:
Given:
Hallway A:
1/10 bulbs
2/10 small bushes
7/10 tree seedlings
Hallway B:
2/10 bulbs
1/10 small bushes
7/10 tree seedlings.
Total flatbed of tree seedlings = flatbed of tree seedlings in hallway A + flatbed of tree seedlings in hallway B
= 7/10 + 7/10
= 14/10
= 1 × 2/5 flatbed of tree seedlings

Answer:
0.128rad/sec
Step-by-step explanation:
Let x represent the between the man and the point on the path
θ = the angle
dx/dt = 4 ft/s
dθ/dt = rate is the searchlight rotating when the man is 15 ft from the point on the path closest to the searchlight
tan θ = x/20 ft
Cross Multiply
20tan θ = x
dx/dt = 20sec² θ dθ/dt
dθ/dt = 1/20 × cos² θ dx/dt
dθ/dt= 1/20 × cos² θ × 4
dθ/dt = 1/5 × cos² θ
Note : cos θ = 4/5
dθ/dt = 1/5 × (4/5)²
dθ/dt = 16/125
dθ/dt = 0.128rad/sec
15x10=150
Subtract 5x5=25 small square cut out
150 -25= 125 sq ft
