A swimming pool holds 480,000 liters of water. The pool has two drainage pipes. When the pool is completely full, the first pipe

sweet-ann [11.9K]

The answer is 96 min, here is why:

x / 240 + x / 160 = 1
2x + 3x = 480 
5x = 480 
x = 96 min

(Drainage rate of first pipe = 480000/240 = 2000 l/min 
Drainage rate of second tube = 480000/160 = 3000 l/min 
Combined drainage rate = 5000 l/min 
Time to drain = 480000/5000 = 96 min. )

Kaylis [27]

Answer:

There is approximately 5.475 liters of blood in the body.

Step-by-step explanation:

At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 ml of blood per beat.

73 ml in liters = $73\times0.001=0.073$ liters

Now, 75 beats/min x 0.073 liters/beat = 5.475 liters/min

And 5.475 liters/min x 1 min/body = 5.475 liters/body

Hence, there is approximately 5.475 liters of blood in the body.

How do you solve 13+4x=1-x

mel-nik [20]

13+4x=1-x
4x=-12-x (minus 13 from each side)
5x=-12 (add x to each side)
You divide -12 by 5x
-12÷5x=2 $\frac{2}{5}$ ⇒2.4
x=2.4
