Answer:
Hence after solving the given equation we get <em>x = 13/20.</em>
Step-by-step explanation:
<em>Given:</em>
<em>-3 x + 0.1 + 10 x = x + 4</em>
<em>-3 x + 10 x - x = 4 - 0.1</em>
<em>6 x = 3.9</em>
<em> x = </em>
<em>x = </em>
<em>x = </em>
Answer:
about 14° south of east
Step-by-step explanation:
The river speed is about ...
(2.35 m/s)×(1 mi/(1609.344 m))×(3600 s)/(1 h) ≈ 5.2568 mi/h
The angle of interest is such that its sine is the ratio of river speed to boat speed:
sin(α) = (5.2568 mi/h)/(21.8 mi/h) = 0.241138
α = arcsin(0.241138) = 13.9537°
Since the river is flowing north, the boat should be directed south of its intended course by this angle.
The boat should be directed 14° south of east.
