By knowing that <em>water</em> outflow is <em>stable</em> and the known geometry, the <em>draining</em> time of the rectangular tank is equal to a time of a minute and 36 seconds.
<h3>How to determine the draining time of a rectangular tank</h3>
In this question we must determine the <em>draining</em> time of a tank whose dimensions are known and whose <em>water</em> outflow is <em>stable</em>. The <em>draining</em> time is equal to the volume of the <em>rectangular</em> tank divided by <em>outflow</em> rate:
V = (1.2 m) · (0.8 m) · (0.5 m)/(0.3 m³/min)
V = 1.6 min
By knowing that <em>water</em> outflow is <em>stable</em> and the known geometry, the <em>draining</em> time of the rectangular tank is equal to a time of a minute and 36 seconds.

Answer:
3x
Step-by-step explanation:
=
Then, for any value x number of computers, there will be 3x students.
144 = 1 x 144, 2 x 72, 3 x 48, 4 x 36, 6 x 24, 8 x 18, 9 x 16, 12 x 12. Factors of 144: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144.
4+2x=10
2x=10-4
2x=6
X=6/2
X=3
