Effectus [21]

Total money=$120
on shirt=$25.65
on socks=$7.98
on a cd=$16.23
on snack=$4.58
so total money left=total money-total money spent
=$120-($25.65+$7.98+$16.23+$4.58)
=$120-$54.44
so total money left=$65.56

A submarine was traveling along the surface of the ocean and decides to dive. If the dive angle is 28° with the horizontal surfa

Alex_Xolod [135]

Answer:

1.5 nautical miles

Step-by-step explanation:

See the attached diagram.

The submarine starts to dive at point A and diving along AB.

If the distance traveled underwater i.e. AB = 1.7 Nautical miles and C is the point directly above its current position at B.

Then Δ ABC is a right triangle having ∠ BAC = 28° {Given}

So, using trigonometry we can write

$\cos 28 = \frac{AC}{AB} = \frac{AC}{1.7}$

⇒ $AC = 1.7 \times \cos 28 = 1.5$ nautical miles.

Therefore, the surface distance that the submarine travels is 1.5 nautical miles. (Answer)
