43 inHg = 43 inHg*2.54cm/in = 109.22cmHg * 10 mm/cm = 1092.2 mmHg
14.7 psi = 760 mmHg
1092.2mmHg * 14.7psi / 760 mmHg = 21.13 psi
Answer: option D. 21.13 psi

Answer:
D. 21.13 psi
Explanation:
Given:
Pressure = 43 inches Hg
There are various units for measuring pressure, this includes:
atmosphere (atm), mmHg (millimeter mercury), Pa (pascals), psi(pounds per square inch)
Unit conversion:
1 in Hg = 0.491 psi
Therefore, 43 in Hg would be:
[tex]=\frac{43 in. Hg*0.491 psi}{1 in.Hg} =21.11 psi[/tex]
