sergeinik [125]

Question

Alice skates 2/5 mile in 1/5 hour. Elizabeth skates 2/3 mile in 2/9 hour. How far did elisabeth escape in in 1 hour?

Answer:

The Correct Answer is \frac{8}{9}

Complete the multiplication and the equation becomes

\frac{2}{9} +\frac{2}{3} = ?

The two fractions now have like denominators so you can add the numerators.

\frac{2+6}{9} = \frac{8}{9}

Therefore, The Answer Is \frac{8}{9}

Hope this helps!

If we digitized music in stereo using 24 bits per sample and sampling the analog signal 96,000 times per second, this would gene
ryzh [129]

The bit stream generated on <em>kilobyte per second</em> would be 2304 kilobytes per second.

<u>Given the Parameters</u> :

  • Number of bits per sample = 24 bits

  • Sampling frequency = 96000 times per second

The bit rate = Sampling frequency × Number of bits per sample

The bit rate = 24 × 96000 = 2,304,000 bits per second

<u>Converting bits to kilobytes</u> ;

<em>1 kilobytes = 1000 bits</em>

(2,304,000 bits per second ÷ 1000) = 2304 kilobytes per second

Therefore, the bit stream generated would be 2304 kbps

PLEASE ANSWER 18 AND 18
seraphim [82]

18 & 18.  I like it.

The square root of a natural number won't be rational unless the number is a perfect square.  So not a and not b but yes to C.

For d, -0.125374..., we can't really tell. The three dots tells us it goes on.  There's no indication of a repeat but we can't assume it doesn't repeat either.   For d the correct answer is cannot be determined.

OK, onto 18.

The square root of 12 is irrational so has a nonterminating, nonrepeating decimal expansion.

7/8 has a finite decimal expansion, 0.875.   When the reduced denominator doesn't have any prime factors besides 2 and 5 we'll get a finite decimal expansion.  Answer: b

5/11 has 11 as a factor in the denominator, so is an infinite repeating decimal.

I'll guess there's three dots after 0.81818181 so that one doesn't terminate either.

---------

Bonus

0.21 rational, equal to 21/100

3/12 rational, it's the ratio of integers

√12 - 2 is irrational because of the √12

4.125... can't really tell because the ... may hide a repeating or nonrepeating part.
