Answer:
3.9
Step-by-step explanation:
each gallon is 1.3
Let's start calculating the value of √(27):
√(27) = √(9*3) = √(9)*√(3) = 3√(3) ≈ 5.196152423
So:
5.196152423 > 5.0
and
5.196152423 < 5.2
Therefore:
5.0 < √(27) < 5.2
Answer:
Area = 200x - x², Max area is 10000m² with dimensions 100m × 100m
Step-by-step explanation:
Total fencing = perimeter
Let length of the sides be x and y,
2(x + y) = 400
x + y = 200
y = 200 - x
Area = x × y
= x(200 - x)
Area = 200x - x²
For max area, convert area into the completed square form
-(x² - 200x)
-(x² -2(x)(100) + 100² - 100²)
-[(x - 100)² - 10000]
-(x - 100)² + 10000
Max area is 10000 m²
Because the least value of (x - 100)² is 0.
That too when x = 100
When x = 100,
y = 200 - x = 200 - 100 = 100
Dimensions are 100m × 100m
2:1 because it decreases my half which is the same as saying 2/1
Side BC corresponds to side SP
AD = RQ
CD = PQ
