Step-by-step explanation:
Let
= mass of the painter
= mass of the scaffold
= mass of the equipment
= tension in the cables
In order for this scaffold to remain in equilibrium, the net force and torque on it must be zero. The net force acting on the scaffold can be written as
Set this aside and let's look at the net torque on the scaffold. Assume the counterclockwise direction to be the positive direction for the rotation. The pivot point is chosen so that one of the unknown quantities is eliminated. Let's choose our pivot point to be the location of . The net torque on the scaffold is then
Solving for T,
or
To solve for the the mass of the equipment , use the value for T into Eqn(1):
Answer:
101
Step-by-step explanation:
The leftover weight that can be put onto the container (x)
x = 24500 - 12300
x = 12200
The amount of crates that can be hauled into the container
x = 12200 / 120
= 101.6667
We need a whole number so we round down.
= 101

Answer: x < 4
Step-by-step explanation:
So, let's look at the problem:
|x + 7| < 11
We want to get rid of extra numbers, so lets get rid of that seven my subtracting it! But make sure you do the same thing on both sides!
x < 4
Your answer would be four! Hope I helped! <3
Answer:
PQ is 50
Step-by-step explanation:
the total is 69 so all you have to do is take what is known, in this case 19 and do 69 minus 19 to get 50
F(x) = 7(x-1)+8
F(1) = 7(1-1)+8
F(1) = 7(0)+8
F(1) = 8
