Jack is running on a treadmill at a speed of 7.2 miles per hour. Assume y = total distance and x = number of hours. A: y=x / 7.2
B: y = 7 + x
C: y = 7.2 x
D: 7.2 = y (x)

c

step-by-step explanation:

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°

do you have a picture of the table

i think the amount would be $140.62
