the anwser would most likely be 3 because you want the LCM
2m is the best estimate. It’s an appropriate measurement.
Answer:
<em>The sea cow can stay under water for 16 minutes.</em>
Step-by-step explanation:
A hippopotamus can stay under water for 15 minutes.
A sea cow can stay under water 
minutes and this is 11 minutes longer than one-third the time a hippopotamus can.
So, "11 minutes longer than one-third the time a hippopotamus can" means: ![[\frac{1}{3}(15)+11] minutes](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B3%7D%2815%29%2B11%5D%20minutes)
Thus, the equation will be: 
Now, solving the above equation, we will get.........
So, the sea cow can stay under water for 16 minutes.
How many numbers from 1 to 50 are multiples of 3?
3, 6, 9, 12, 15, 18 .......
Let's change the start and end value of the array and find the number of terms
Start at 3 and go all the way to 48 because those are the first and last multiples of 3 in this array.
There is a formula that allows us to quickly find the number of terms
We subtract the first term from the last term and divide by the amount of increase, then we add 1.
(48 - 3) / 3 + 1 = 16 numbers are exactly divisible by 3.
We have 50 numbers and 16 of them divisible by 3
16 / 50 = 8 / 25 probability
Decimal : 0.53
percentage : 53%
