Solution:
q ∧ r : q and r
q r q∧r
T T T
T F F
F T F
F F F
p ∨ (q∧r)
p OR (q AND r)
p q∧r p∨(q∧r)
F T∧ T=T T
F F∧T = F F
F T ∧ F=F F
F F ∧ F =F F
If P is false , The row which represents when p ∨ (q ∧ r) is true is →→F T T T
Which is Option E.
We can write an equation to represent this problem:
.525x=25.83
Divide by .525
x=49.2
52.5% of 49.2 is 25.83
A. $44.91
7 5/8 = 7×8 + 5
= 61/8
= 7.625
since a yard costs 5.89
then 7.625 yards will cost
= 7.625 × 5.89
= $44.91
