Ms. harris is stocking up on dry-erase markers for the upcoming school year. she used 56 dry-erase markers last year and plans to use at least that many for next year. the number of markers in each box is two more than three times the number of boxes she purchased for this upcoming school year. which of the following inequalities can be used to determine b, the number of boxes she purchased.

Step-by-step explanation:

Here, b represents the number of boxes she purchased for this upcoming school year,

Also,  The number of markers in each box is two more than three times the number of boxes she purchased for this upcoming school year.

⇒ The number of marker in each box = 3b+2

Now, the total number of marker = Number of boxes × Number of marker in each box

Since, she plan to use at least 56 marker in the upcoming year,

That is, the total number of marker ≥ 56

Which is the required inequality that shows the given situation.

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°
