I believe it’s carbon dioxide, because you use your respiratory system to breathe in oxygen, and oxygen goes through your circulatory system. And you breathe out CO2.
No. They are called prescription glasses for a reason. However, you can buy reading glasses without a prescription. My mum buys them from the dollar store and they work quite well and last a long time. Hope this helps at least a little bit. Have a nice day.

Answer:
31.5 hours
Explanation:
<em>The given mixed fractions in hours above are the following:</em>
1. 6
2. 11
3. 13
First, let's convert them into improper fractions so we can get their <u>decimal values</u>. All you have to do is to <em>multiply the denominator to the whole number.</em> Then, <em>add the product to the numerator</em>. The sum will be the <em>improper fraction's numerator.</em><em> Copy the denominator.</em>
Let's solve.
- 6
= 6x4 = 24 - 24+1 = 25
= 6.25
Project A took 6.25 hours to finish.
- 11
= 11x2 = 22
= 11.5
Project B took 11.5 hours to finish.
- 13
= 13x4 = 52
= 13.75
Project C took 13.75 hours to finish.
Now that we know their decimal values, we can now add them together.
- 6.25+11.5+13.75 = 31.5 hours
The total time spent on all projects is 31.5 hours.
