Step-by-step explanation:
20 divided by 10 equals two
4136/8= 517
The others
7116/8=889.5
4309/8=538.625
9406/8=1175.75
RB: $51.10/14=$3.65 per lb
Turkey: $42.60/12=$3.55 per lb

Answer: Turkey is the LEAST expensive
Answer:
Volume = ⅓n²(n-1) or ⅓(n³ - n²)
Step-by-step explanation:
Given
Solid Shape: Right pyramid
Edge= n units
Height= n - 1 units
Required
Volume of the pyramid
The volume of a right pyramid is
Volume = ⅓Ah
Where A represents the area of the base
h represent the height of the pyramid
Since it has a square base;
The area is calculated as follows
Area, A = edge * edge
A = n * n
A = n²
Recall that
Volume = ⅓Ah
Substitute n² for A and n - 1 for h
The expression becomes
Volume = ⅓ * n² * (n - 1)
Volume = ⅓n²(n-1)
The expression can be solved further by opening the bracket
Volume = ⅓(n³ - n²)
I would say you cannot use a rectangle. Or a circle. One of those.
