Answer:
54.8 Nm
Step-by-step explanation:
Torque is the cross product of the radius vector and force vector:
τ = r × F
Another way to write it is the product of the radius and force magnitudes times the sine of the angle between the vectors.
τ = rF sin θ
Here, r = 0.366 meters and F = 155 Newtons. F is in the +y direction, and r is 15° below the +x axis, so the angle between the vectors is 90° − 15° = 75°.
τ = (0.366 m) (155 N) (sin 75°)
τ = 54.8 Nm

1. 1 dozen for $1.50
y = 1.5x where x = # of dozens
2. 1 bottle for $0.16
y = 0.16x where x = # of bottles
3. 1oz for $0.12
y = 0.12x where x = # of oz
Answer:
They will need to hire 5 testers.
Step-by-step explanation:
This question can be solved using a simple rule of three.
For each 10 developers, we need 2.5 testers. So how many testers are needed for 20 developers?
10 developers - 2.5 testers
20 developers - x testes
![10x = 20*2.5](https://tex.z-dn.net/?f=10x%20%3D%2020%2A2.5)
![10x = 50](https://tex.z-dn.net/?f=10x%20%3D%2050)
![x = \frac{50}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B50%7D%7B10%7D)
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
They will need to hire 5 testers.
