Answer:
The force exerted by the weight lifter is 81.7 N.
Step-by-step explanation:
We can find the force exerted by the weight lifter using the definition of work:
(1)
Where:
F: is the force
d: is the displacement
We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:
Therefore, the force exerted by the weight lifter is 81.7 N.
I hope it helps you!
Answer:
As e is point between df. So we can write df as
df = de + ef
As given df = 78 , de = 5x - 9 , ef = 2x + 10.
So we can write
78 = 5x - 9 + 2x + 10
78 = 7x + 1
On subtracting 1 on booth side
78 - 1 = 7x +1 - 1
77 = 7x
On dividing both side by 7.
11 = x
So x = 11.
So ef = 2x + 10 = 2*11 + 10 = 22 + 10 = 32

Answer:
The perimeter is 40 units.
Step-by-step explanation:
First multiply the width by 2
6 2/3 * 2 = 13 1/3
Now take two 6 2/3 and two 13 1/3 an add them
6 2/3 + 6 2/3 + 13 1/3 + 13 1/3
= 40
