Answer:
Answer:
t ≅ 5.09 min
Step-by-step explanation:
we have that if in 4000 L/sol there is 132 kg salt and the pumping speed is 12L/s, we must find how much of salt is pumping per second and then find the amount of salt remaining
12L/s*132kg salt/4000L = 0.396 Kg salt/s, this means that 0.396 kg per second comes out , It should be found that the amount of salt must be drained so that only 11 kg of salt remain
132kg salt - 11 kg salt = 121 kg salt, so
121Kg salt*s/0.396Kg salt ≅ 305.55 s ⇒ 305.55s*min/60s ≅ 5.09 min
Step-by-step explanation:
Answer C. The pattern is that each number in sequence 1 is being doubled to get the number in sequence 2, and 40*2=80

Answer:
-120 , split it into diferent parts.
Step-by-step explanation:
12 (52) - 12 (62) = ?
12 x 52 = 624
12 x 62 = 744
624 - 744 = -120
