Which pair of undefined terms is used to define the term parallel lines?point and line
plane and line
point and ray
ray and line

Answers

Answer:

The correct answer for this is : A. Point and Line

Step-by-step explanation:

The lines are said to be parallel to each other if they do not intersect each other at any point. So, for any number of lines to be parallel we must have lines and no intersection points between them then only we can say the given number of lines are parallel to each other

So, the terms which are used to explain the term parallel lines here are : line and the point.

And the both terms point and a line are undefined in the geometry.

Hence, the correct answer for this is : A. Point and Line

The pair of undefined terms are used to define the term parallel lines are point and line. Option A. This is further explained below.

What are parallel lines?

Generally, parallel lines are simply defined as Two lines in the same plane that are always exactly the same distance apart and are said to be parallel.

In conclusion, If there is no point at which the lines meet, then we say that they are parallel to one another. Therefore, in order to state that a particular set of lines is a set of parallel lines, we must first establish that there is a set of lines with no junction points.

We know he talked for over 3 minutes since the total is 305 which is > 125 (the cost of 3 minutes). The remaining amount he paid is 305-125= 180. He was charged 15 per 10 seconds which amounted to 180. 180/15=12 which means he was charged 12 times. Each time charged it was because he took 10 seconds so in total he took 12x10= 120 second. That’s 2 minutes. The two minutes he was charged 15s plus the first 3 minutes he was charged 125 is 5 minutes. We can plug in the numbers to make sure we are right. If he talked for 5 minutes then we know for the first three he was charged 125 and the additional two he was charged 15s (s representing 10 seconds). We can put the 125 aside for now to figure out the 15s. If he took two minutes then he took 120 seconds. Divide that by 10 because he’s getting charged per 10 seconds not per second so that’s 12. 15(12) is 180. 125 + 180 is 305

Which costs more per issue, an 18-issue subscription for $40.50 or a 12-issue subscription for $33.60? Explain. (Make sure to show your work and explain your solution Plz.)

Answers

You have to divide total price by "18 times" for the first and by "12 times" for the second.

So,

The 18-issue subscription costs $(40,50)/(18) =\$2.25$ per issue.
The 12-issue subscription costs $(33,60)/(12) =\$2.80$ per issue.

Therefore the 12-issue subscription costs more per issue.

The 18-issue subscription costs 40.50/18. You divide 40.50/18. It is 2.25 per issue
The 12-issue subscription costs 33.60/12. You divide 33.60/12. It is 2.80 per issue

Therefore: The 12-issue subscription costs more than the 18-issue subscription.
