The correct answer is 7.2
We can subtract 2 from 4, which is 2.
They're both in the same decimal place, so that is why they are affecting each-other.

Bearing is a topic that deals with the <em>distance</em> and<em> location</em> of a given object with respect to a <u>reference</u> point. Thus in the given question, the ship is <u>57.23 km</u> to the yacht.
<em>Bearing</em> is a topic that considers the <u>distance</u> and <u>position</u> of a given object with respect to a<em> reference</em> point. Thus the <u>angles</u> are usually measured with <em>reference</em> to the north pole.
Thus to solve the given question, let the required <em>distance</em> be represented by x.
Applying the <em>cosine rule</em>, we have;
= + - 2ab Cos C
The angle C between the line from <u>ship to tugboat</u> and from <u>tugboat to yacht</u> can be determined as;
C = +
C =
Thus,
= + + 2(36 x 27) Cos
= 1296 + 729 + 1944(0.6429)
= 2025 + 1249.8
= 3274.8
c =
= 57.2259
c = 57.23
Therefore, the <em>distance</em> from the ship to the yacht is <u>57.23 km</u>.

Answer:
Time = 500 seconds or 8.333 minutes
Step-by-step explanation:
Time = Distance/Speed
Speed of light = 3 x 10^8 meters/second
Distance=1.5 X 10^11 meters
Time = 1.5 X 10^11 meters/3 x 10^8 meters/second
We solve using the scientific notation. When 8 is taken to the top it is subtracted from 11 ( the base 10 is the same -- laws of exponents)
Dividing 1.5 by 3 gives 0.5 .
Time = 1.5 X 10^(11- 8) meters/3 meters/second
Time = 0.5 X 10^3 seconds
Time = 500 seconds
Dividng seconds with 60 will give minutes
Time= 500/60 = 8.333 minutes
