Compound percentage reduction can be calculated by multiplying the initial number by (1-x)^t where x is the percentage reduction (/100, i.e. 1% reduction is 0.01), and t is the number of times it has reduced.
So:
a)

Where t is the number of weeks.
We can then just substitute in to work out the final pressure:
b) p = 45*0.94^6 =
31psi
Given,
∠AOE = 30°
∠DOB = 40°
So, ∠EOD = 180 - (30+40) [angles on a straight line]
= 180 - 70
= 110
∠EOD = ∠COF [ vertically opposite angle]
∴ ∠COF = 110°
47 is 0.47 and 2/3 is 0.66
