Someone 100 points to answer 2 questions! spell everything out because i have more questions like this and i have no idea how to do them a. it is not 5^3 b. i have no idea

I gotcha!

First answer is A.

Second answer is also A.

See screenshots below if your interested in how it's solved :)

A.

easy, remember rules of exponents

the only one you need to know for this question is this one: \frac{x^m}{x^n}=x^{m-n}

also x^{-m}=\frac{1}{x^m}

so in this case

\frac{5^5}{5^8}=5^{5-8}=5^{-3}=\frac{1}{5^3}

answer is 1st option

B.

same as A

answer is 1st option

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
