Depth is 3.81
Step-by-step explanation:
V = l x w x d
11.43 = 2.5 x 1.2 x d
11.43 = 3 x d
÷3
3.81 = d
Hope this helps!
Given:
adults = x
male = 7x + 1
female = (7x + 1)/2
total number of people = 82
x + (7x + 1) + [(7x +1)/2] = 82
2x/2 + (14x + 2)/2 + (7x + 1)/2 = 82
2x + 14x + 2 + 7x + 1 = 82 * 2
23x + 3 = 164
23x = 164 - 3
23x = 161
x = 161/23
x = 7
adults = x = 7
males = 7x + 1 = 7(7) + 1 = 49 + 1 = 50
females = (7x+1)/2 = 50/2 = 25
7 + 50 + 25 = 82
Answer:
160,000 Nm
2667 Nm/sec
Step-by-step explanation:
Work = weight * distance
= 800 * 200
= 160,000 Nm
Power = rate of work done
= 160,000 / 60
= 2667 Nm/sec
The area is one square centimeter
