Answer:
Step-by-step explanation:
perimeter of larger hexagon=2.5 perimeter of smaller hexagon
1/2*bh=75
1/2*bb=75
b^2=150
b=rt(150)=12.2
not sure what you mean by link, but 12.2 is approximately the length you're seeking
Answer:
maximum is 16,853 cell phones
≤ 18.853
Step-by-step explanation:
1,176,912.42. per quarter budget
247,638.00 per quarter fixed cost
We subtract then divide the amount cost of phones and ensure its less or rounded down.
1,176,912.42 -247,638 = 929274.42
929274.42 / 55.14 = 16853
16,852 < m ≤ 16,853
24
It goes into 24 once and into 48 twice
