I believe the answer is B.
90% = 0.90 as a decimal.
It's asking for how much is covered for $66.60 per month. So, if you multiply 0.9 by $66.60 you'd get 59.94.
Cos (180) = - 1
I just plugged it into a calculator.
-5*-2=-10
The factors to multiply to give negative 10 is -5 and 2
6 plus negative two gives you negative four. The factors to add to give you -4 is 6 and -2
Answer:
Step-by-step explanation:
Let x ft be the length of the fence and y ft be the width of the fence.
1. The length of the habitat should be at least 80 feet, then
2. The perimeter of the habitat should be no more than 300 feet. The perimeter of the fences 2x+2y ft, then
3. The system of inequalities that represent the model is
The graph of these inequalities is attached.
Two possible solutions are
1. x=100 ft, y=20 ft (100≥80 and 2·100+2·20=240≤300);
2. x=110 ft, y=30 ft (110≥80 and 2·110+2·30=280≤300).
