Answer:

It takes 500 seconds

Step-by-step explanation:

Light travels at a rate of  3.0 × 10^{8} meters per second.

Distance of earth from the sun is 1.5 × 10^{11} meters.

We have to calculate the time it takes to reach the earth from sun

Since speed = \frac{Distance}{Time}

3.0 × 10^{8} = \frac{1.5\times 10^{11}}{T}

T = \frac{1.5\times 10^{11}}{3\times 10^{8}}

  = 0.5 × 10^{11} × 10^{-8}

 = 0.5 × 10^{11-8}

  = 0.5 × 10^{3}

  = 500 seconds.

It takes 500 seconds for light to travel from the sun to the earth.

I am assuming you mean 3.0 *10^8 and 1.5 * 10^11.

time = distance/speed right. So, 
t = 500 s

Solve each equation. Show your work<br><br> 13a=-5<br> 12−b=12.5<br> -0.1=-10c
amid [387]
1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385

The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)

-b/-1= 0.5/-1
Therefore b=-0.5

The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10

Hence, c= 0.01

1- Line:
A line is a one dimensional figure that is formed by joining an infinite set of points.
It has no start and no end.
Answer:
Line ..............> A) infinite number of points extending in opposite directions that has only one dimension

2- Line segment:
It is the same as the line. The only difference is that a line segment has a fixed start point and a fixed end point. It is considered to be a portion of a line
Answer:
Line segment .........> D) a part of a line that has two endpoints

3- Ray:
A ray is also a one dimensional shape. A ray usually has a start point but no end point.
Answer:
Ray .........> B) part of a line that has one endpoint and continues in one direction infinitely

4- Point:
A point is a dimensionless geometric shape. It is only used to state a certain location.
Answer:
Point .........> C) a location, has no dimension

5- Vertex:
A vertex is a term that is used to refer to the point where the two rays forming an angle meet.
Answer:
Vertex ........> E) the common endpoint of two segments or rays that form the corner of an angle

Hope this helps :)
