R1t+t/2.5=1, we are told it takes both 1.5 hours so
1.5r+0.6=1
1.5r=0.4
r=4/15
So for this other pipe to fill the pool by itself...
4t/15=1
4t=15
t=15/4
t=3.75 hours
check..
4t/15+t/2.5=1
(4t+6t)/15=1
10t=15
t=15/10
t=3/2
t=1.5 hours, correct (for both pipes filling the pool)
B. False
Bi = 2
Binomial = 2 possible outcomes
Answer:
B and C are correct
Step-by-step explanation:
Original price=A
A x 25/100=$31.14
simplify 25/100 = 1/4
A x 1/4=$31.14
A/4=$31.14
multiply both sides by 4
A=$124.56
