Explanation: Set up your equation as you read through the problem.

"What" means <em>x</em>, "is", <em>equals</em>, "30%", <em>30/100</em>, "of", <em>times</em>, "546", <em>546</em>.

So our equation reads x = 30/100 · 546.

Simplifying on the right side of the equation,

we can reduce 30/100 to 3/10.

So we have x = 3/10 · 546.

Now multiply across the numerators and denominators to get 1638/10.

This reduces to 819/5 which can be written as 163.8.

Is an imaginary "line" from the Earth to the Moon a line, a ray, or a segment? and WHY?
sesenic [268]

Answer:

Segment

Step-by-step explanation:

It is a segment because it has two endpoints (the Earth and Moon). If it was a ray, it would go on forever in one direction. It doesn't, so the imaginary line is a segment.  

The first image is a segment, the second is a ray.

Hope this helps. :)
