Subtract a from both sides of the equation.
b=−a+14
1.530 divided by 10 is your answer
Answer:
Step-by-step explanation:
60% = 7.2/12
83% = 10/12
He improved by a supposed 23%
The first thing we should know in this case is that by definition the flow of liquid is given by:
Q = V / t
Where,
V: volume
t: time
The volume of the cone is given by:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Substituting the values we have:
V = (3.14 * ((3) ^ 2) * 7) / (3)
V = 65.94 in ^ 3
We now turn off the time of the flow equation:
t = V / Q
Substituting values:
t = (65.94) / (14)
t = 4.71 minutes
Answer:
It will take for all the liquid in the funnel to pass through the nozzle about:
t = 4.71 minutes
60% = 0.6
12 / 0.6 = 20
answer 12 is 60% of 20
