Answer: Martha spend $537.25 in june to have the same average as in the first quarter.
Step-by-step explanation:
Given that,
Average monthly expenditure for the first quarter= $396.25
Expenditure in April= $401.50
Expenditure in May= $250.00
Suppose, expenditure in June= x
To have the same average as in the first quarter, we have to take the average of the second quarter equals to the average of first quarter.
So,
Average monthly expenditure for the second quarter= $396.25
Using the formula of average for monthly expenditure for second qaurter as follow:
Average monthly expenditure for months April, May, and June= Sum of expenditure of April, May, and June divided by 3.
So,
396.25= (401.50 + 250.00 + x)/3
1188.75= 651.5 + x
x= 537.25
The correct answer is: [C]: " 1/4 " .

(-3/8) + (5/8) = (-3 + 5) / 8 = 2/8 ;
→ 2/8 = (2÷2) / (8÷2) = 1/4 ; → which is: Answer choice: [C]: " 1/4" .

Answer:
Step-by-step explanation:
We could use the Law of Sines if we only knew what angle A was. It just so happens that by the Triangle Angle-Sum Theorem, angle A is equal to
180 - B - C. Therefore,
angle A = 180 - 11 - 75 so
angle A = 94. And the Law of Sines is
and cross multiply to get
600sin94 = asin11 and solve for a:
gives you that
a = 3136.85
Let x ft be the lenght 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 fenceis 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
- x=100 ft, y=20 ft (100≥80 and 2·100+2·20=240≤300);
- x=110 ft, y=30 ft (110≥80 and 2·110+2·30=280≤300).
