Basile [38]

Answer:Volcanic eruptions are very dangerous events.

Yuri [45]

Answer:

<h2>1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low),</h2>

Explanation:

HCT is calculated as:

HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100  

1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT  ranges from 38 to 46% (some sources claim 34.9-44.5%).

*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.

Total blood volume = Packed cell volume + plasma volume.
