A store down the street is selling a console 50% of from 236.87 if i were to buy the console wit my 490.45 how much money will i get back?

Answers

Answer:

$372.01

Step-by-step explanation:

50% of $236.87 is half of it, which means the console is being sold for $118.44 because:

235.87/2 = 118.435

Round this to the nearest cent:

$118.44

If you have $490.45, and you spend $118.44, it means that you subtract the cost from your own money:

490.45 - 118.44 = 372.01

You will have $372.01 left.

A rock is thrown down from a cliff that is 180 m high. The function
h(t) = -5t^2 – 10t + 180 gives the approximate height of the rock
above the water, where h(t) is the height in metres and t is the time
in seconds. When will the rock reach a ledge that is 105 m above
the water?

Answers

Answer:

t = 3

Step-by-step explanation:

105 = -5t^2 -10t + 180

-75 = -5t^2 -10t

15 = t^2 +2t

t^2 +2t -15 = 0

(t+5)(t-3)

t = -5, 3

There's no such thing as negative time so you use the positive answer

Have you ever thought that it would be nice not to have to worry about things like capital letters and punctuation? What if you could use them any way you wanted--or not at all?There was, in fact, a society that did just that. Ancient Greek writing contains no punctuation. There was no need to decide when to capitalize a letter, because all the letters were capitals. The earliest Greek writing did not even have spaces between words.Here is your goal for this assignment:Use sentence and mechanics skills in compositionFor this project, you are to put your imagination to work. Picture a society (perhaps imagine yourself living in it) with no punctuation or capitalization rules. Brainstorm all the effects this could have. Perhaps you might foresee confusing or humorous situations that could arise.Write an essay of at least 400 words illustrating your understanding of the importance of standards for capital letter and punctuation use. You may communicate this understanding through expository or narrative writing, and may be as serious or humorous as you wish, as long as you convey the idea of the importance of these language mechanics.Remember to write an introductory paragraph and a good conclusion. Write sentences that require different kinds of punctuation. This assignment will give you an opportunity to use commas, apostrophes, hyphens, quotation marks, and parentheses.60 POINTS!!!!!!!!!!
