Which equation represent the proportional relationship between the amount of seaweed powder and the amount of fish powder in the fertilizer?

The correct answer is B. f = 2/5s

Step-by-step explanation:

For finding out the proportional relationship between the amount of seaweed powder and the amount of fish powder in the fertilizer, we will use this expression:

Amount of fish powder = f

Amount of seaweed powder = s

Proportion = Amount of fish powder/Amount of seaweed powder

Proportion = 8.6/21.5 = 0.4 = 2/5

Proportion = 27.4/68.5 = 0.4 = 2/5

Now, we can affirm that the equation that represents this proportional relationship is f = 2s/5

The correct answer is B. f = 2/5s

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
