Answer:
they're equal
Step-by-step explanation:
Trick question. They're equal. 80/100 can be simplified to 8/10 by dividing by 10. if you type them both in a calculator, they both equal .80
<span>d = 20 inches
r = d/2 = 20/2 = 10 inches
Area = πr^2
= 22/7 * 10^2 inch^2
= 2200/7 inch^2
= 314.2 inch^2
Therefore, Answer is B. 314.2 in^2 Ans</span>

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
