Two cargo ships are sailing a direct course into harbor. Ship A is 22 miles from harbor. Ship Bis sailing into harbor on a cours
s344n2d4d5 [400]

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

cos(x) = \frac{adjacent}{hypotenuse}

cos(47) = \frac{22miles}{hypotenuse} .... flip both fractions.

\frac{1}{cos(47)} = \frac{hypotenuse}{22miles} .... multiply both sides by 22

\frac{22mi}{cos(47)} = hypotenuse

32.26mi = hypotenuse = B

So the distance of ship B from the Harbor is 32.26 miles

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Help ill give you 25 points
lisov135 [29]

Answer:

  • 7

Step-by-step explanation:

<u>3n+2 is divisible by p:</u>

  • 3n + 2 = px

<u>8n+3 is divisible by p:</u>

  • 8n + 3 = py

<u>Solve each equation for n:</u>

  • n = (px - 2)/3
  • n = (py - 3)/8

<u>Eliminate n and solve for p:</u>

  • (px - 2)/3 = (py - 3)/8
  • 8(px - 2) = 3(py - 3)
  • 8px - 16 = 3py - 9
  • 8px - 3py = 7
  • p = 7/(8x - 3y)

As we see p could get 1 or 7 as natural number. Since 1 is excluded, the only solution is 7, and 8x - 3y must equal to 1.
