The total cost of the least expensive fence would be $800.
To minimize perimeter and maximize area we take factors that are as close to equal as possible. In this case, the closest whole number factors are 200 and 100. Since the north and south faces cost less, we will make those 100 ft and make the more expensive east and west faces 200 ft.
100 ft × $2/ft = $200 per side × 2 sides = $400 for the north and south facing sides.
200 ft × $1/ft = $200 per side × 2 sides = $400 for the east and west facing sides
$400 + $400 = $800
Answer:
Yes, the cost 
in dollars and the amount of yogurt 
are proportional.
The equation is: 
Step-by-step explanation:
1. If varies directly as , you can write it as following:
Where 
is the constant of proportionality.
2. Let's calculate the value of the constant of proportionality. If 
and 
, you have:
3. Then, the equation is:
4. Let's verify if they are directly proportional. Substitute 
which is the amount of yogurt bought by Jonah. The result must be $0,48:
5. They are directly proportional.

Answer:
i) ∠AOB = 87°
ii) ∠BOC = 72°
iii) ∠COD = 123°
iv) ∠AOD = 78°
Step-by-step explanation:
The first three angle measures can be read from the diagram. Find the rays that define the angle, and read the measure of the arc between them.
The last angle, AOD, is found using the fact that the sum of all of the angles around a point is 360°.
87° +72° +123° +∠AOD = 360°
∠AOD = 360° -282° . . . . . . . . . . subtract 282° from both sides
∠AOD = 78°
18 days. It is the least common denominator of the two numbers.
