b.) 9/36

c.) I really don't remember how to do the "order doesn't matter" thing anymore, so idk. my best idea is for you to look up the formulas for permutation and combinations. I know it has to do with that

A honeybee flaps its wings 200 times per second.how much time is required for one wingbeat? give your answere in millisecond

Fiesta28 [93]

The time required for one wing beat is 5 milliseconds.

<em><u>Explanation</u></em>

Lets assume, the time required for one wing beat is $t$ seconds

So, the time required for 200 wing beat $= 200t$ seconds

Given that, the honeybee flaps its wings 200 times per 1 second. So...

$200t=1 \\ \\ t=\frac{1}{200}seconds\\ \\ t= (\frac{1}{200}*1000 )milliseconds\\ \\ t=( 5 )milliseconds$

So, the time required for one wing beat is 5 milliseconds.

What is 5/20 as a percent if you could give an explanation that would be good but if not thats okay

Liono4ka [1.6K]

5/20 can also be represented as 25/100 or 25%. The can be done by multiplying the top and bottom both by 5 and then dividing our numerator (25) by our denominator(100) to get the %.
