When separating a mixture using the property of size, which of the following separation methods would you use? A. magnetism B. distillation C. evaporation D. filtration
Answer:
D
Explanation:
The answer is Filtration
When separating a mixture using the property of size, filtration is used in the separation methods would you use. The correct option is D.
What is filtration?Filtration is a process of separating different substances from each other. It is done to separate the different substances from each other. These substances can be solid, gas and liquid.
There are different processes of separation to separate different substances. These processes are magnetism, distillation, evaporation, and filtration.
Magnetism is the process used to separate magnetic substances from nonmagnetic substances. Evaporation is a process of separating the substance from a high boiling point to a low boiling point. Filtration is used to separate using the property of size.
Thus, the correct option is D. filtration.

If a person consumes 50% of their daily kilocalories from carbohydrates and 30% from protein, what percentage of their daily kilocalories will come from fat?
The percentage of daily kilocalories of the person that come from fat is 20%.
The diet of a person is composed mainly of carbohydrates (C), proteins (P) and fat (F), that is, the sum of the 3 sources amount to 100% of the consumed kilocalories. Given that 50% of the daily kilocalories of this person come from carbohydrates and 30% come from protein, the percentage that comes from fats is:
[tex]C + P + F = 100\%\\F = 100\% - C - P\\F = 100\% - 50\% - 30\% = 20\%[/tex]
The percentage of daily kilocalories of the person that come from fat is 20%.
