It would be: 311*84 / 100 = 311 * 0.84 = 261.24
So, your answer is 261.24
You would most likely choose the purple one the answer is A and perimeter is 8
From (1), we get x = (8 - 3y) / 2 ––(3)
Substitute (3) into (2),
2 [(8 - 3y) / 2]² + 3y² = 110
(8 - 3y)² + 3y² = 220
15y² - 48y - 156 = 0
Therefore y = 5.2, then x = (8 - 3×5.2) / 2 = -3.8
OR y = -2, then x = [8 - 3×(-2)] / 2 = 7
The cordinates of A and B are (-3.8, 5.2) and (7, -2).
Answer:
19.21
Step-by-step explanation:
When you draw this out, it forms a right angled triangle with h = 12miles, and base = 15 miles.
So, the distance between them = the hypotenuse of this triangle.
Square root of (15^2 + 12^2) = 19.209...
Round to nearest hundredth = 19.21.
