Explain how precipitation happens. Use complete sentences and give at least two supporting details

Answers

Answer:

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. ... Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth.

Step-by-step explanation:

the sun evaporates the water from a stream or some type of water source and it then gets collected into the clouds and then condensation and the last step is when the water is too heavy so the clouds release it and that is called precipitation. hope this helps.

Answers

Answer: is C

Step-by-step explanation: you have a 90 so 90-78 is 12

The answer is 12

We know that angles AFB and CFD and BFC sum up to 180

Using this information we can write the equation

AFB + CFD +BFC = 180

Now substitute known values:

78 + 90 (it is a right angle) + BFC = 180

Now solve-

Answers

Answer:

a. 14

b. 1

c. 2

Step-by-step explanation:

If there are 4 one point questions and 5 two point questions, then 5 multiplied by two is 10 and adding it to 4 is 14. The quiz would be 14 points total. If you scored 87.5% on the quiz then you would know that you got 12 of the questions correct and you would know that by finding 87.5% of 14 which the equation to do so would be 87.5/100= 0.875, then 0.875* 14= 12.25. If you round 12.25 to the nearest whole number then it's 12. And since you got all the 1 point questions right, then you must of gotten 1 two point question wrong.

I hope this helps!

3+4g=11, subtract 3 from both sides

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.

Answers

Answer:

U first need to find out the total number of people

22+28

and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator

22/50

And now to make it into % we need to ALWAYS multiply the fraction by 100

22/50 x 100

44%

Hope it helps

Answer:

44 %

Step-by-step explanation:

okay so 100% is equal to the whole team or 50 swimmers

100% = 50 swimmers

to find out how much one swimmer is would be to divide the 100% by the total of swimmers.

100% / 50 swimmers

2% = 1 swimmer

so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.

2 x 22 = 44

Liam ___________ (necesitar) in Coche Nuevo Compare and contrast Antony and Brutus speech at the funeral of Julius Caesar in terms of characteristic trait and effectiveness on Roman mob?.There is a sharp contrast between the funeral speeches of Brutus and Antony in Julius Caesar. Antony's funeral oration differs from Brutus's in many ways. Brutus's speech to the crowd of people is the speech of a philosopher while Antony's speech is emotional and is intended to stir the feelings and passions of the listeners. Brutus's speech is cold, logical, and intellectual; while Antony's speech is charged with feeling, and it is meant to excite the emotions of the listeners. Brutus's speech appeals to the intelligence of the listeners, and it fails because the listeners in this case are not intelligent enough.Brutus's speech is really an excellent specimen of reasoning. The logic behind the arguments in this speech is perfectly clear. But logic is something which the common people do not understand. This does not mean that Brutus is speaking to people who are utterly ignorant. The point is that the people understand Brutus's reasoning only to a limited extent. As for the logic in his speech, here is an example: "Not that I loved Caesar less, but that I loved Rome more". This sentence is a simple enough and yet not so simple. There is certainly an element of complexity in this sentence. Brutus tries to appeal to people's love of freedom. He tries to stir their hatred of tyranny. But the does not realize that the people are not very enlightened and that that they do not really understand this talk about freedom and slavery. In the starting scene, this mob has already been depicted as admirers of Caesar, the conqueror. A love of freedom is far from their thoughts. And yet they accepts Brutus's reasoning. But the crowd's ignorance comes out in their declaring that Brutus should be given the title of Caesar. It is clear that the crowd does not understand the principles for the sake of which Brutus had murdered a dear friend. On the other hand, Antony knows the psychology of the mob. He appeals directly to this psychology. He does not talk of the principal of freedom. He does not talk of evil of tyranny and slavery. He speaks about the wounds which had been inflicted upon Caesar's body. He speaks about the ingratitude of Brutus who was loved as a dear friend by Caesar. He speaks about Caesar's will by the terms of which Caesar had left much of his property to the people in general. Antony makes use of several rhetorical devices in the course of his speech. He makes use of irony when he says again and again that Brutus is an honourable man.However, we find another important difference in this respect. Brutus speaks to the mob in prose, while Antony speaks in verse. Poetry is always more effective than prose. It is also always more emotional than prose. Antony's speech makes use not only of rhetorical devices but also of poetic devices. Antony's speech is an excellent combination of art, cunning, and sincerity. Besides, Brutus speaks about abstract notions while Antony speaks in concrete terms. Brutus speaks of freedom and slavery, while Antony speaks of his listeners feelings and passions.Did i did something wrong and help find more quotes...
