800 is to the nearest hundred
Answer:
if you toss a dice 30 times, you will roll a two 5 times.
Step-by-step explanation:
If you toss a dice once, the probability of rolling a 2 is 1/6, like you said.
So if you multiply your chances of rolling a 2 by 30, you get;
30.1/6 = 30/6 = 5
Answer:
24x + 41
Step-by-step explanation:
Distribute the 6.
6(4x + 5) + 11 = 24x + 30 + 11
Now we just add the 30 and the 11 which are at the back of the expression.
24x + 30 + 11 = 24x + 41
Therefore the answer is 24x + 41. Please mark brainliest if possible and i hope you get a good grade on your homework
<em>x</em>/<em>r</em> + <em>x</em>/<em>w</em> + <em>x</em>/<em>t</em> = 1
<em>x</em> (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>) = 1
<em>x</em> = 1 / (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>)
To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, <em>rwt</em> :
<em>x</em> = 1 / (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>) • <em>rwt</em> / <em>rwt</em>
<em>x</em> = <em>rwt</em> / (<em>rwt</em>/<em>r</em> + <em>rwt</em>/<em>w</em> + <em>rwt</em>/<em>t</em>)
<em>x</em> = <em>rwt</em> / (<em>wt</em> + <em>rt</em> + <em>rw</em>)
