in college there are 12 times as many students as professors. If together the students and professors number 32,500, how many students are there in the college?

Answers

The answer is 16,345 students

Answer:

2708

Step-by-step explanation:

If there are 12 times as many students as professors all you have to do is divide the amount of students my 12 (32,500/12)

32,500/12 = 2708.3333 (3 keeps repeating)

Obviously there is not 0.333 repeating professors, cant have 0.3 of a professor so just round down to 2708

if f(x)=7x-7 what is f(8)+f(4)

Answers

Given Function is

f ( x ) = 7x - 7 ------- eqn ( 1 )

Now , put the value of x = 8 in eqn ( 1 )

f ( 8 ) = 7 ( 8 ) - 7f ( 8 ) = 56 - 7f ( 8 ) = 49 ------- eqn ( 2 )

Now , put the value of x = 4 in eqn ( 1 )

f ( 4 ) = 7 ( 4 ) - 7f ( 4 ) = 28 - 7f ( 4 ) = 21 ------- eqn ( 3 )

From eqn ( 2 ) nd eqn ( 3 ) we get,

f ( 8 ) + f ( 4 )49 + 21 70

If Lan was highlighting the multiples of 5 on a hundreds chart, which numbers would be highlighted? Which of these numbers are prime numbers? Explain.

Answers

Only 5 would be a prime number because all the other numbers are divisible by 5 as well so they wouldn't only have 1 and themselves as a divisor.

You divide the polygon into smaller shapes, rectangles suit this best.

There will be 2 rectangles:

1st rectangle whose length is 24ft and its width is 11 ft (21-10=11).

2nd rectangle its length is 10ft and its width is 7ft.

You find the area of both rectangles. The formula of finding the area of a rectangle is length X width.

1st rectangle has an area of 264 ft² (24 X 11)

2nd rectangle has an area of 70ft² (10 X 7)

Add the area of the two angles to get the area of the polygon.

Musicians can be restricted in the songs they play in public. They can be banned from performing in certain venues. Total censorship of recorded music can be achieved by banning certain music from stores, radio, or the Internet. Songs can be altered to conceal portions considered forbidden. One argument for censorship is that it protects impressionable people from explicit content or ideas deemed immoral. A July 2015 article on Connect US: The Global Issues Blog lists this reason as the number one censorship argument: "By regulating the songs which are being played on the airways," the author said, "people, especially teens, will not be exposed to lyrics that have profanities and violent overtones." Censorship is a cocoon. Another argument for censorship is that it regulates the music industry. The idea is that music producers encourage artists to create offensive songs, which become popular and increase earnings. Music censorship forces music producers to eliminate offensive material and keep the profits rolling in. Censoring music limits intolerance, some say. Writing for the Vision Launch website, Crystal Lombardo explained this notion in her February 2016 article. "Sometimes, music targets a certain individual or society and disrespects them," she wrote. "With censorship, the youth can better discern between whats right and whats wrong." Yet another argument for censorship concerns violence. Here, the reasoning is that if music glorifies violence, then it might incite children and even adults to act violently. People who do not want music censored argue that it shackles artistic expression. It restrains the ability of song writers and singers to express their creativity and promote social change. Opponents to music censorship also claim that songs with controversial content provide a useful purpose. The music challenges individuals to think. People should be free to hear new ideas and then decide whether the ideas are valuable to them. Another criticism of censorship is that it destroys an individuals freedom by imposing the censors views. A person should be able to listen to whatever song he or she wants to hear. That person can decide if the song is offensive. In her Vision Launch article, Lombardo offers a related problem with censorship. "Some artists have had their songs censored because the lyrics were interpreted in a bad way," she said. Here is one example of misinterpretation. Phil Collins 1981 hit, "In the Air Tonight," has been banned from the airwaves at least twice. Once in 1991 due to a supposed connection to the Persian Gulf War and after the 9/11 terrorist attacks. Yet, the song is not political. Lingering tension from a recent divorce inspired Collins to write the song. But surely the most prominent proof: the song was written many years before either event even occurred! side note:Madonna has often been censored for religious controversy and being too racy. Snoop Dogg has been censored for everything from personal physical fights to profanity, drugs, and guns. John Lennon (along with The Beatles) was censored for anti-war themes and drugs. If anything, censorship seems to increase artists popularity even though it dampens their artistic expressions. Which ONE claim from Passage 2 is BEST supported with relevant and sufficient evidence from the text? A Censorship regulates the music industry. B Censorship makes it difficult for artists to express themselves. C Music lyrics that include violence may cause violent behaviors in those who listen to it. D Incorrect interpretation of music lyrics leads to wrongful censorship. The author of Passage 2 claims that "Censorship is a cocoon." Which ONE sentence from Passage 1 BEST supports this claim? A "These rights ensured liberties by limiting the governments ability to interfere with citizens lives." B "A person is free to decide if an idea is worthwhile without pressure from government officials to choose one idea over another." C "They can erect the barbed wire fence of censorship whether others consider it right or wrong." D "The music had to be clean and free of profanity, which was somewhat of a Green Day hallmark."
