Answer:
2t blocks
Step-by-step explanation:
We measure these distances from Jim's house.
The school is t blocks from Jim's house. Twice that is 2t blocks. Thus, the library is 2t blocks from Jim's house.
Answer:
The given question is
<em>
Draw two 1 dm squares on a sheet of paper. Draw a diagonal on each one and cut them out.</em>
<em />
So, you need to draw square with sides of 1 dm. However, first, you need to transform from dm to cm.
We know that 1 decimenter (dm) equals 10 centimeters (cm).
That means the square sides are 10 centimerers long. So, you need to draw two squares like the first image attached shows.
Then, to draw their diagonals, you need to draw a line segment from one corner to its opposite corner, you should have an inclined line acroos each square. As the second image attached shows.
There you have it. Two squares of 1 dm side with on diagonal each.
6x-8
2(3x-5) use the distributive property to get 6x-10
6x-10 is not the same as 6x-8 so the two equations are not equivalent.
As John Steele mentioned, the reason that we can’t ‘unfold’ the surface of a sphere (that is, as I take your meaning, place it onto a flat surface) has to do with the Gaussian curvature of the surface. Bending or even tearing the surface into pieces won’t change this curvature. The surface of a sphere and that of a flat surface have fundamentally different Gaussian curvatures which cause this to be impossible.
Consider extending some radius outwards from a point and drawing a circle at this radius. On a flat surface (ie euclidean) we measure this to be of length 2πr. On the surface of a sphere however we will always measure a smaller length than this. As an extreme example to illustrate this is true we can imagine starting at the north pole and having a radius that extends all the way down to the south pole - at this fixed radius the circle would have zero length - quite different than the same radius in euclidean space.
So if we want to press some section of a spherical surface onto a flat surface it becomes apparent that we will need to tear it at some point because we have a smaller circumference on our section than the flat surface has. What Gaussian curvature gets at however is that this phenomena exists in the space itself - down to an infinitesimal limit. We wouldn’t just have to tear our surface along one point to make it flatten - it ends up that every point in that space would have to be torn. I’m sure that you could imagine how this is problematic to our ideal ‘unfolding’ of the surface - its not much of a transformation if we need to tear it up into infinitesimal pieces.
