Answer:
228 hydrogen atoms
Step-by-step explanation:
In a water molecule,
1/3rd is oxygen atoms, and
2/3rd (1 - 1/3 = 2/3) is hydrogen atoms
If there are 114 water molecules,
Total number of atoms would be:
3 * 114 = 342 (1 oxygen and 2 hydrogen atoms in 1 water molecule)
Out of these, 2/3rd would be hydrogen atoms, so:

There would be 228 hydrogen atoms
Because the account is compounded continuously, Euler number is required
e = 2.7182818

Did you write the first two answers in pencil ?
They're correct ! Just do the other two exactly the same way.
-- Do the division problem printed in the "Distance ..." column.
-- Multiply the answer by 0.1 .
-- Write the new answer in the last column.
The equation for cosine is the adjacent/hypotenuse. Looking at our L, the letter right next to it is the lowercase l, so that is the adjacent. The hypotenuse is always the side opposite the right angle, so the hypotenuse in this question is the lowercase m. The answer for the first question, then, is k/m. For the second question, you are asked to find the side of q. In questions like these, always start from the angle given to you. Start from the 51 degrees. Right next to the 51 degrees is q, so q is the adjacent. We also have a number, 134, which is opposite the given angle 51. Now use the trigonometric ratio that involves adjacent and opposite, which is tan. Therefore, tan51 is the right answer. Hope this helps! Ask me for more help.
Use the execution method or in other words use the substitute method and go from there..
