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.

What is neurotransmitter?
A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell.
In the synaptic cleft, where they can interact with receptors on the target cell, neurotransmitters are released from synaptic vesicles. The receptor that the neurotransmitter attaches to determines how the neurotransmitter affects the target cell. Numerous neurotransmitters are produced from easy-to-find, abundant precursors such amino acids, which are frequently converted in a limited number of biosynthetic steps.
