Hardest question of all time can you solve it?

the pressure in an automobile tire filled with air is 245.0kpa. if po2 = 51.3kpa, pco2 = 0.10kpa, and pothers = 2.3kpa, what is pn2 ?

PN2 = 191.3kPa

Step-by-step explanation:

Ptotal = PO2 + PCO2 + PN2 + Pothers = 245.0kPA

Work backwards to find PN2

245.0kPA - PO2 - PCO2 - Pothers = PN2

245.0kPA - 51.3kPa - 0.10kPa - 2.3kPa = PN2

245.0 - 51.3 = 193.7

193.7 - .10 = 193.6

193.6 - 2.3 = 191.3

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
