Answer:
Cost of Material per square foot = $1.7
Step-by-step explanation:
Given:
Length = 24
Width = 12
Height = 6.5
Find:
Cost of Material per square foot
Computation:
TSA of pit = 2[bh + hl] + lb
TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)
TSA of pit = 2[78+156] + 288
TSA of pit = 756 square foot
Cost of Material per square foot = 1,285.20 / 756
Cost of Material per square foot = $1.7
The other parallel side is 44 m
Step-by-step explanation:
Let us revise the formula of the area of a trapezium
, where
and
are its parallel bases- h is its height (The distance between the two parallel bases)
∵ The area of a trapezium is shaped field is 480 m²
∴ A = 480 m²
∵ The distance between two parallel sides is 15 m
∴ h = 15 m
∵ One of the parallel side is 20 m
∴
= 20 m
We need to find 
Substitute all these value in the rule of the area below
∵ 
∴ 
- Multiply the two sides by 2
∴ 
- Divide both sides by 15
∴ 
- Subtract 20 from both sides
∴ 
The other parallel side is 44 m

The solution is shown in the photo
Each person will pay $7 before taxes and tip.
Step-by-step explanation:
Price of salad = $4
Price of two salads = 4*2 =$8
Price of sandwich = $6
As 4 friends ordered sandwiches, therefore,
Price of 4 sandwiches = 6*4 = $24
Price of slice of cake = $3
Total = 2 salads + 4 sandwiches + 1 slice of cake


5 friends will split the bill evenly, therefore,
Bill for one person = 
Bill for one person = 
Each person will pay $7 before taxes and tip.
