As an improper fraction it would be 23/10 then as a mixed number it would be 2 3/10
Greatest to Least : -0.4, -9/16, -1 3/8, -1.55
Change them into decimal form and -9/16 = -0.5625 . -1 3/8 = -1.375
Answer:
B. 73.19 mi/hr
Step-by-step explanation:
First we need to define the angles from a common reference. Robin's watercraft is moving 75° west of south, which is the same as 15° south of west. The river is flowing at 75° south of west.
The watercraft velocity relative to the water is:
wx = 70 cos 15° ≈ 67.615
wy = 70 sin 15° ≈ 18.117
The river's velocity is:
rx = 6 cos 75° ≈ 1.553
ry = 6 sin 75° ≈ 5.796
Robin's net velocity is:
vx = wx + rx ≈ 69.168
vy = wy + ry ≈ 23.913
The speed (magnitude of velocity) is:
v = √(vx² + vy²)
v ≈ √(69.168² + 23.913²)
v ≈ 73.19
