Describe the factors that affect energy use worldwide.
guajiro [1.7K]

Answer:

The more you use, the more you have

When you drink water (or any liquid).

Explanation:Similar for food: From a caloric standpoint, a McSupersized extra value meal should provide you with plenty of fuel to use.  But how do you feel after you eat one of those?  Unless you’re starving, less is more when it comes to food.Same for sleeping: Logging in 12-hour sessions seems like it should ready you for the day, but usually it leaves you dragging.  Unless you’re sleep deprived, it’s worth seeing what happens when you sleep just a little less.Healthy people drink a lot of water, as well they should.  But consider when you’re drinking that water: If you’re drinking it with your meal, you could be impairing your digestion.Not only does water dilute the gastric juices required to digest food, it also exits the stomach after just a few minutes, taking those juices with it and making digestion difficult.  And since digestion accounts for 5 to 15 percent of your energy expenditure, that’s something you should care about.

Jack invested $500 in the shares of a company x and $750
-BARSIC- [3]

Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

First step is to calculate x return on investment

x return on investment = $600 - $500

x return on investment= $100

Second step is to calculate y return on investment

y return on investment= $900 - $750

y return on investment= $150

Now let determine the ratio of return on investment from company x to that from company y

Using this formula

Ratio of return on investment=x return on investment/y return on investment

Let plug in the formula

Ratio of return on investment=100/150

Ratio of return on investment=2/3

Ratio of return on investment=2:3

Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

Suppose that prolog facts are used to define the predicates mother(m, y) and father(f, x), which represent that m is the mother
erastova [34]

Prolog languages are logics that are used when creating programs that require artificial intelligence.

The prolog rule to define the predicate grandfather(x, y) is grandfather(X,Y) :- mother(M,Y), father(X,M); father(F,Y), father(X,F)

<h3>How to determine the prolog rule</h3>

From the question, we have the following definitions:

  • mother(m, y): m is the mother of y
  • father(f, x): f is the father of x

For x to be the grandfather of y, then either of the following definitions must be true

  • m is the mother of y, and x is the father of m
  • f is the father of y, and x is the father of f

Using the above highlights, the prolog rule would be

grandfather(X,Y) :-

mother(M,Y), father(X,M);

father(F,Y), father(X,F)
