Answer:

The distance between two ships to the nearest tenth place is, 24.1 km

Step-by-step explanation:

Using Pythagoras theorem:

\text{Hypotenuse side}^2 = \text{Adjacent side}^2 +\text{Perpendicular side}^2

As per the statement:

Two ships are near a buoy in the open ocean. One ship is 20 km due north of the buoy, and the other ship is 13.5 km due east of the buoy.

You can see the diagram for this problem as shown below.

Let x be the distance between the two ships.

Hypotenuse side = x km

Adjacent side = 13.5 km

Perpendicular side = 20 km

Apply the Pythagoras theorem:

x^2 = 13.5^2+30^2 = 182.25+400 = 582.25

⇒x = \sqrt{582.25}

Simplify:

x = 24.129857024 km

Therefore, the distance between two ships to the nearest tenth place is, 24.1 km

Answer:

Quadratic function, None of the above, and ?

Step-by-step explanation:

So remember what I told you about earlier, lets look at that first one.

So we can see that x is increasing by 1 and y is decreasing by 3...And then it increases by 3! And after that another 9! Well, that seems like it is reversing, as it changes from decreasing to increasing in y coordinates. So knowing that is reverses from decreasing to increasing in y, <u>it must be a quadratic function</u>!

Next we have a increase in 1 and a decrease by 17...then 12...then 7 in y. This isnt decreasing by a constant amount like a linear function. It doesnt seem like a obvious exponential decrease either, and it isnt reversing like a quadratic function does. I am going to use something called logarthms, which you don't even need to think about yet, just to make sure that it is not an exponent.  Althouhg the difference in the exponent was only 0.0018, it is a differnece.<u> So this must be a none of the above</u>, sicne none of the functions apply. (If this is incorrect, and it is exponential, then the test is wrong. While the method I used is something found in mid algebra 2, it is still a method of finding a exponent of a number.)

Now we finish up with a change in x of 1, and a change of y by...-11, -11, -11!

Well, what do you think this is, thinking back on what I have said so far.

It is a constant change of -11y and 1x. Remember, a CONSTANT CHANGE.

What do you think it is :)

If you cannot figure it out, let me know in comments.

<u>Hope this is helps you!</u>

Jamal has 1240 song on his mp3 player, and 40% of the songs are rock songs. how many are not rock songs?
Colt1911 [192]
Total songs = 1240 
Rock songs = 40%
Songs that are not rock = 100 - 40 = 60%

It would be: 1240 * 60% = 1240 * 0.60 = 744

In short, Your Answer would be 744

Hope this helps!

Supplementary means they add up to 180, so you can write an equation:
3x + 2x - 25 = 180
5x - 25 = 180
+ 25
5x = 205
÷ 5
x = 41
I hope this helps!
