Th
e value that is being asked for in the question is 0.4. If the polygon is dilated into 2.24 units and its length would be 5.6 units originally, then the value of the scale factor should be .4. I got this through multiplying 5.6 units to each of the choices below, and the one that yielded 2.24 units exact is 0.4

Lewis earned $1800 from his summer job at the grocery store. This is $250 more than twice what his friend Tara earned. Right and
Rus_ich [418]

Answer: Tara earned $775 from her summer job.

Step-by-step explanation:

Let x represent the amount of money that Tara earned from her summer job.

Lewis earned $1800 from his summer job at the grocery store. This is $250 more than twice what his friend Tara earned. The equation would be

2x + 250 = 1800

Subtracting 250 from the left hand side and the right hand side of the equation, it becomes

2x + 250 - 250 = 1800 - 250

2x = 1550

Dividing the left hand side and the right hand side of the equation by 2, it becomes

2x/2 = 1550/2

x = 775

What is 2+2= to. My teacher says its not four im confused.
Ostrovityanka [42]

Answer:

Because they aren't equivalent. Prolog allows the definition of symbols as inline operators using the op/3 predicate, which allows one to convert arbitrary compounds to formulae and back again.

Step-by-step explanation:

Since 2+2 is a compound with arity 2 and 4 is just an atom unification is impossible and the query fails. To actually do arithmetic equivalence you must use =:=/2 (2 + 2 =:= 4). To solve arithmetic problems you must use is/2 or use an interpreter with arithmetic constraint extensions.Yes, the moment you begin to tie math to real world items, it can turn false very quickly. For example:

(2 red balls + 2 blue balls = 4 orange balls) = false

(2 women + 2 women = 4 men) = false

(2 cats + 2 mice = 4 dogs) = false

(2 oxygen as a single molecule (o₂) + 2 oxygen as a single molecule (o₂) = 4 oxygen as a single molecule (0₄)) = false

That is to say, in the real world there is often non-numerical 'metadata' in additional to the numbers being added, such that a perfect equality (beyond mere quantity) is false. This 'metadata' would include everything from size, to composition, to structure, to color, to temperature, to species, to intelligence, to flavor, to temperament, to physical laws of union and relation, and many other properties.
