The Cooking Club made some pies to sell during lunch to raise money for a field trip. The cafeteria helped by donating three pies to the club. Each pie was then cut into six pieces and sold. There were a total of 72 pieces to sell. How many pies did the club make?

The number of pies did the club make is 9 pies.

Step-by-step explanation:

Step 1 :

Pies given by cafeteria = 3 pies

∴ Number of pieces helped= 36 = 18 pieces

Step 2 :

Remaining pieces = Total pieces - helped pieces

⇒ 72-18 = 54 pieces

The number of pies made by club = Remaining pieces / pieces from one pie

⇒ 54/6

⇒ 9 pies

the answer is 24

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°
