the circle is closed because it can also include that number or be equal to it, when the circle is open that number isn't an option and is just a starting point.

State one form of the Law of Cosines and provide a trick for writing the other two forms and explain when Law of Cosines should
Yuki888 [10]

Solving for <em>Angles</em>

\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos∠C \\ \frac{a^2 - b^2 + c^2}{2ac} = cos∠B \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos∠A

* Do not forget to use the <em>inverse</em> function towards the end, or elce you will throw your answer off!

Solving for <em>Edges</em>

\displaystyle b^2 + a^2 - 2ba\:cos∠C = c^2 \\ c^2 + a^2 - 2ca\:cos∠B = b^2 \\ c^2 + b^2 - 2cb\:cos∠A = a^2

You would use this law under <em>two</em> conditions:

  • One angle and two edges defined, while trying to solve for the <em>third edge</em>
  • ALL three edges defined

* Just make sure to use the <em>inverse</em> function towards the end, or elce you will throw your answer off!

_____________________________________________

Now, JUST IN CASE, you would use the Law of Sines under <em>three</em> conditions:

  • Two angles and one edge defined, while trying to solve for the <em>second edge</em>
  • One angle and two edges defined, while trying to solve for the <em>second angle</em>
  • ALL three angles defined [<em>of which does not occur very often, but it all refers back to the first bullet</em>]

* I HIGHLY suggest you keep note of all of this significant information. You will need it going into the future.

I am delighted to assist you at any time.

Ghani is going to use these instructions for fizzy drinks 5 parts lme juise 3 parts lemonade he thinks he has 300ml of lime juse
lina2011 [118]

Answer:

The greatest amount of fizzy drink he can make is 480 ml

Step-by-step explanation:

The ingredients for a fizzzy drink is 5 parts lime juice and 3 parts lemonade

Therefore, we have a total portion of 5 + 3 = 8 parts

Since there ar more parts of lime juice per fizzy drink, we calculate based on lime juice

Also dividing the proportions by we get

5/5 part lime juice and 3/5 parts lemonade or

1 part lime juice and 3/5 parts lemonade or

Thus we have 300 ml lime juice and 3/5× 300 ml lemonade or

300 ml lime juice and 180 ml lemonade = 480

The greatest amount of fizzy drink he can make = 480 ml.

erma4kov [3.2K]

Answer:

30 people

Step-by-step explanation:

100 people to the survey. And the question is practically asking how many people are left. So we have to subtract 60 from 100. And then subtract 10.

1.) 100 - 60 = 40

2.) 40 - 10 = 30

Hope this helps you out! : )
