Electronegativity<span> is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most</span>electronegative<span> element) is assigned a value of 4.0, and values range down to caesium and francium which are the least </span>electronegative<span> at 0.7.</span>
Answer:
x < 2
Step-by-step explanation:
Given
10x > 8(3x - 2) - 12 ← distribute parenthesis on right side
10x > 24x - 16 - 12, that is
10x > 24x - 28 ( subtract 24x from both sides )
- 14x > - 28
Divide both sides by - 14, reversing the inequality symbol as a result of dividing by a negative quantity.
x < 2
Answer:
Step-by-step explanation:
Amount of brine = 100 gal
amount of salt = 80 lb
rate of water running = 4 gal / min
Let A be the amount of salt in lb in the tank at any time t.
(a) dA/dt = rate of salt in - rate of salt out
Rate of salt in = 0
rate of salt out = A x 4 / 100 = A / 25 lb/min
So, dA/dt = 0 - A/25 = - A/25 lb/min
When t = 0, A = 80 lb
So,
(b) Now, A = 40 lb
So,
take log on both the sides
t = 17.3 minutes
