Answer:
Procedure in option C only works.
Step-by-step explanation:
We have to select the process in which Mrs. Smith can help her to work 30 divided by 3.
(A) (27 divided by 9) + (9 divided by 3) = 3 + 3 = 6
But (30 ÷ 3) = 10 ≠ 6
(B) (24 divided by 4) + (4 divided by 4) = 6 + 1 = 7 ≠ 10
(C) (21 divided by 3) + (9 divided by 3) = 7 + 3 = 10
(D) (20 divided by 4) + (10 divided by 4) = 5 + 2.5 = 7.5 ≠ 10
So, procedure in option C only works. (Answer)

Answer:
528000 ft²
Step-by-step explanation:
The Pyramid Arena has a shape of a square pyramid. A square pyramid is a pyramid with a square base and the top point is directly above the center of the base. It consist of 5 faces (base and 4 triangles), 8 edges and 5 vertices.
Given:
length of base (b) = 600 ft and height of lateral face (h) = 440 ft.
Since the lateral faces are made of glass, the area of each lateral face is the same as the area of a triangle with base same as base length and height same as height of lateral face.
Therefore, area of each lateral face = 1/2 × b × h = 1/2 × 440 × 600 = 132000 ft²
The lateral faces are made almost completely of glass and they are 4 lateral faces, therefore the total area of the glass in the Pyramid Arena = 4 × 132000 ft² = 528000 ft²
