Answer:
A = 846 in²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the diagonals ) , then
A = × 36 × 47 = 18 × 47 = 846 in²
Answer: the answer is 120 for it the area but that is not on the answer list.
Step-by-step explanation:
Answer:
0 = $0.00
1 = $3.00
2 = $6.00
3 = $9.00
Step-by-step explanation:
Answer:
Cost function = 40a + 500
Cost of 90 articles = $4,100
Step-by-step explanation:
The fixed cost is $500 and it will.not change regardless of production level.
The Variable cost is $40 and increases by every additional unit produced.
Assume the number of articles produced is a.
Cost function would be:
Total cost = Variable cost * Number of articles + Fixed cost
TC = 40a + 500
Using this, the cost of 90 articles is:
= 40 * 90 + 500
= $4,100
