Hi there!
Let's solve this problem step by step!
A bottle contains 70% alcohol. First we need to convert this percentage into a decimal. To do this, we only need to divide by 100.
70 % = 70 / 100 = 0.7
The entire bottle contains 500 ml of solution. To find the amount of alcohol in the solution, we must multiply our (just found) decimal by the total content of the bottle.
0.7 * 500 ml = 350 ml
Therefore there are 350 millimetres of alcohol in the solution.

Answer:
During the year 2021.
Step-by-step explanation:
As we have a function that defines the annual per capita out-of-pocket expenses for health care, we can work with it.
Knowing that, <u>we clear x</u> (<em>this is the number of years past the year 2000, so it will contain our desired information</em>).
Now, as we want to know when are the per capita out-of-pocket expenses for health care predicted to be $1400, and <em>this total is our variable y</em>, then
Finally, we know that <u>x is the number of years past the year 2000</u>, so the answer is that during the year 2021, <em>the per capita out-of-pocket expenses for health care are predicted to be $1400</em>.
60,000,000,000 in scientific notation is 6 x 10^10 so you move the decimal 10 times.
