24/30 = 12/15 = 4/5
this is the simplified form
240 people surveyed did not like any of the top three types of music.
This question is complicated. But, based on the words, I would say that doubles is the key word. First we have to figure out how far it is between 11 and 2. Now we are going to turn 2 into a 2 digit number, since it is after 12 then we are going to add 12 to this number. 12+2=14. So now we are going to subtract 11 from 14. Leaving us with 3.
Now we know that there are 3 meters at 2, and it doubles every hour.
So we are going to take the square root of 3. ![\sqrt{3} =1.732050808](https://tex.z-dn.net/?f=%20%5Csqrt%7B3%7D%20%3D1.732050808%20)
So that means that it was at 1.732050808 at 1 pm.
Now we are going to take the square root of that number.![\sqrt{1.732050808} =1.316074013](https://tex.z-dn.net/?f=%20%5Csqrt%7B1.732050808%7D%20%3D1.316074013%20)
Which means that at noon it was at 1.316074013.
And finally take the square root of that number. ![\sqrt{1.316074013} =1.14720269](https://tex.z-dn.net/?f=%20%5Csqrt%7B1.316074013%7D%20%3D1.14720269%20)
So now we know that at 11 am it was at 1.14720269 meters.
I hope that helps, if you need any further help on this or any other problems just ask.
The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
