A ship sails on a bearing of 020° for 30 km.
zepelin [54]

Answer:

The ship travels approximately 10.261 meters to the East.

Step-by-step explanation:

At first we introduce a graphical description of the statement as an attachment below. Let suppose that bearing is respect to the North-direction, then the change in position in the East direction is modelled by the following Trigonometric formula:

x = r\cdot \sin \theta (1)

Where:

r - Distance travelled by the ship, measured in kilometers.

\theta - Bearing angle, measured in sexagesimal degrees.

x - Distance component in the east direction, measured in kilometers.

If we know that r = 30\,km and \theta = 20^{\circ}, then the distance in the East direction is:

x = (30\,km)\cdot \sin 20^{\circ}

x \approx 10.261\,m

The ship travels approximately 10.261 meters to the East.

What percent of 2000 is 160?<br> Show work
ArbitrLikvidat [17]

Hello from MrBillDoesMath!

Answer:

.08%

Discussion:

Let the percent be denoted "p". Then

2000 * p% = 160 =>     ( as p% = p/100)

2000* p/100 = 160 =>

20p = 160 =>

p = 8 or .08%

3x over 2x-6 plus 9 over 6-2x
Mars2501 [29]
Answer: 3/2
Explanation:
3x/2x-6 + 9/6-2x
= 3x/2x-6 + 9/-(2x+6)
= 3x/2x-6 + -9/2x-6
= 3x/2x-6 - 9/2x-6
= 3x - 9/2x-6
= 3(x-3)/2(x-3) (cancel out x-3)
= 3/2
