Which set contains rational numbers?
neonofarm [45]

Rational numbers are any numbers that terminate (the decimal ends somewhere)

The only set that does this is D, since

\sqrt{25}  = 5

All other sets have these:

\sqrt{47}  \:  \sqrt{7}  \: \pi

None of these terminate (the decimals goes on forever), so the answer is D

Olive buys indie music online. Each song costs $2 plus a $5 fee for using the artist's site. She has no more than $40 to spend.
SCORPION-xisa [38]
In constructing an inequality, you need to know the following:

1. What don't we know? How many songs can be bought? So, let x be the numbers of songs.
2. What do we know? Each songs costs $2 plus a fee for using the artist's site of $5.
3. Is there more than 1 possible solution? Yes, because there is enough money left if she only bought 1 song.

The meaning of no more than $40 means it must not exceed $40, $40 or less, or only $40.

So, song + fee can't be more than $40 and song + fee could equal to $40.

Therefore, song + fee for using an artist's site less than or equal to $40.
Final Answer: 2x+5 <= 40
