Answer:
its the second one
Step-by-step explanation:
Answer:
the bottom one is 1/2 which is a equal so the bottom one
5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489
So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.
Answer:
7/12
Step-by-step explanation:
Answer:
h greater-than-or-equal-to negative 432
Step-by-step explanation:
* multiply each side by -24 *

IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )
Thus,
h ≥-432
Which can also be expressed as h is greater than or equal to negative 432
Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.
