The answer is:  "1" .
________________________________
Explanation:
________________________
To start, we find this coordinates of this "point that splits the segment in half", known as the "half-point"; or, even more formally, known as the "midpoint",  using the following "midpoint formula"; in which "M" refers to the "midpoint":
____________________________________
Given two coordinates (points) on a (straight line segment): 
______________________________
(x₁, y₁) ; AND:  (x₂ ,y₂ ) ;  

The midpoint , "M":
___________________________________
M = (x₁ + x₂) / 2  , (y₁ + y₂) / 2  ;
____________________________________

in which:   " (x₁ + x₂) / 2 " ; refers to the "x-coordinate" of the midpoint;
 
AND:        "(y₁ + y ₂) / 2 " ; refers to the "y-coordinate" of the midpoint;
_______________________________________________________
       If given two particular points, use can use point to start with, as long os the second one is used for the next one:
___________________________________________________
So, given:  Point A:  (4,3) ;  4 = x₁ ; 3 = y₁ ;
                  Pont B:  (-2,6)   -2 = x₂ ; 6 = y₂ ;
___________________________________________________
 The midpoint , "M":
___________________________________
M = (x₁ + x₂) / 2  , (y₁ + y₂) / 2 = ?  Substitute the values:
_______________________________________________
M = [4 +(-2)] / 2 , (3 + 6) / 2 ;
  
→    [(4 <span>− 2) / 2 ] , [(3+6) / 2 ] ;

</span>→ (2/2), (9/2) ; 

→ (1, 4.5)
__________________________________
The midpoint is: (1, 4.5).  This very question asks to find the "x-value" of the midpoint, which is "1" .  (Since:  x =1, y = 4.5).   
________________________________________
So, the answer is: "1" .

If globes are better at showing the Earth accurately, why do we still use maps?
vredina [299]

Answer:

Even though globes are showing Earth more accurately, the maps are still used because they are more practical.

Explanation:

Earth is generally shown with two methods, one being the maps (map projections) and the other being globes. Both are used and will be used, as both have several advantages, but also several disadvantages. Despite globes being closer and more accurate in their representation of Earth, the maps are still used because they are much more practical.

The globes show Earth very close to its true form, though they are made as a ball, not as an ellipsoid. Anyhow, the globes don't have distortions of areas, so the sizes and locations are accurate on them. On the other hand, globes are highly impractical because of their shape, as they are don't often fit in standard backpacks or bags, and can easily be broken or damaged. Also, we can not see the entire Earth at any moment, so it is hard to make comparisons by using them.

The maps, on the other side, do have inaccuracies, mostly by having distortions, be it around the Equator or around the poles. Despite this, they have a relatively good accuracy that in most cases is enough for practical usage. Also, their form and weight make them easy to use, move from place to place, and the entire world can be seen at the same time, thus they are very practical when it comes to making comparisons.

The sea surface temperatures and ocean climate zones of Western and Northern Europe are like those of the East Coast of the Unit
MrRa [10]

Answer:

Geographic proximity of the gulf stream.

Explanation:

  • The sea surface temperature of the oceanic climate and the zone of the western and northern Europe are same as that of the eastern coast of the united stated as these are located on the higher latitudes as the climate of the western Europe is similar to that of the subtropical and the semi-arid in the southern parts and that of the Mediterranean humid climate that is induced by the North Atlantic current.  
  • <u>The northern parts are closer to the baltic plains and the mainland of the Greenlands as the entire region climate is mostly impacted by the gulf stream and that brings the cool and cold subarctic and arctic type of climate.  And the presence of the boreal forests that are also found in the tundra region. </u>
  • While that of the eastern coasts of the U.S have a temperate type of climate and the warm summer, cold and snowy winters and mild winters in the southern parts.
