I know that 20% is out of 100.If I changed this problem to be a fraction problem,I would change that percent to 20/100.55 would be the denominater of the other fraction.Right now we're trying to find the numerator for the denominator of 55 to make this a complete fraction.Secondly,I would try to find a common denominator to get my answer.I'm going to make the common denominator......5500.As my teacher always said what you do to the bottom you do to the top and it goes the other way around too.So, i will times 20*55 to get my numerator.This equals 1100.Now I would divide this fraction by 100 to get my finished answer.The answer is 11 is 20% of 50.
I believe it’s c) complementary
Answer:
It will take 13.5 minutes for the liquid to reach - 10.8°C.
Step-by-step explanation:
The initial temperature of the experiment is 0°C and as the experiment goes on, the temperature of the liquid is changing at a rate of - 0.8°C per minute.
So, the equation that models the situation is
T = 0 - 0.8t
⇒ T = - 0.8t ................. (1)
Where T is the temperature of the liquid in °C and t is the time of spending after the experiment starts in minutes.
Now, given T = - 10.8°C and we have to find the corresponding time (t) in minutes.
So, from equation (1) we get,
- 10.8 = - 0.8t
⇒ t = 13.5 minutes
Therefore, it will take 13.5 minutes for the liquid to reach - 10.8°C. (Answer)
