Answer: it turned 115.8°

Step-by-step explanation:

The triangle formed is shown in the attached photo. The angle turned by the ship in the north west direction is ange A. To determine angle A, we would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes

165² = 111² + 83² - 2(111 × 83)CosA

27225 = 12321 + 6889 - 2(9213)CosA

27225 = 19210 - 18426CosA

18426CosA = 19210 - 27225

18426CosA = - 8015

CosA = - 8015/18426

CosA = - 0.435

A = Cos^- 1(- 0.435)

A = 115.8° to the nearest tenth

Dominos.com allows you to build your own pizza online, but it only reveals the price at the end of the process. Watch
Ede4ka [16]

Answer:

Hi there!

Your answer is:

Domino's waits to reveal the price until the end because, psychologically, you're predisposed to put & LEAVE more toppings on your pizza. If you see how each topping affects the price of the pizza each time you add one, you may limit the amount you choose. If you wait until the end to see it, by that point you think "Well I <em>need</em> these toppings on there to make it delicious." From a business standpoint, it's more financially beneficial to use the "hide the price until the end" system. However, from a consumer standpoint, most prefer seeing a live breakdown of how each topping affects the price so we can limit what we pay to a reasonable amount.

I hope this helps!

1+4=5 2+5=12 3+6=21 8+11=?
ziro4ka [17]
Okay so we just need to find out the pattern...
in this case the pattern is adding..
we did 
1 + 4 = 5 
2 + 5 = 12
we figure this one out by adding 2 and 5 twice so it look like this 
2 + 5 + 5 = 12 
now moving on to our next one 
3 + 6 = 21 
so we added 3 and added 6, three times so look
3 + 6 + 6 + 6 = 21 
so now 
8 + 11 = 96 because we added 8 and added 11, eight times look..
8 + 11 + 11 + 11 + 11 + 11 + 11 + 11 + 11 = 96 
so our answer to 8 + 11 is 96!
hope this helps:)
and don't forget 2
