Which typing time is the fastest? A. 320 words in 8 minutes; B. 600 words in 12 minutes; C. 350 words in 10 minutes; D. 225 word
Natasha2012 [34]

Answer:

B - 600 words in 12 minutes

Step-by-step explanation:

So most of this has to do with division. So let's look at answer one

320 words in 8 mins

320/8 = 40 words per minute.

600 words in 12 minutes

600/12 = 50 words per minute

350 words in 8 minutes

350/8 = 35 words per minute

And finally, 225 words in 5 minutes

225/5 = 45 words per minute. Thus, the answer is B

Which of the following is equivalent to
enot [183]

Answer:

Option (2) is correct.

18-\sqrt{-25}=18-5i

Step-by-step explanation:

Given expression 18-\sqrt{-25}

We have to find an equivalence value to the expression.

<u> Radical rule</u>,

\sqrt{-a}=\sqrt{-1} \sqrt{a}

Also,i=\sqrt{-1}

Consider the given expression,

18-\sqrt{-25}

Applying radical rule to \sqrt{-25}

\sqrt{-25}=\sqrt{-1}\sqrt{25}=5i

Thus, the expression becomes,

18-\sqrt{-25}=18-5i

Thus, option (2) is correct.
