Answer:
The product of any two rational numbers is therefore a rational number, because it too may be expressed as a fraction. For example, 5/7 and 13/120 are both rational numbers, and their product, 65/840, is also a rational number.
Step-by-step explanation:
Answer:
B. 
Step-by-step explanation:
We have been given a system of equations. We are asked to choose the ordered par that is the solution to the given system.
To solve our given system, we will equate both equations as:
Combine like terms:
Upon substituting 
in equation (1), we will get:
Therefore, the ordered pair is the solution of the given system and option B is the correct choice.
You would use the Pythagorean Theorem a²+b²=c² and re-arrange to get a²=c²-b² then you would put the numbers in and get a²=130²-50² so a²=14400 and if you square root that you get 120. So the height of the mast is 120 feet.
Answer:
£1.95
Step-by-step explanation:
£41.01 + £49.54 + £12.50 = £103.05
£105 - £103.05 = £1.95
For the horizontal segment, the value of the ordinate will not change. Then the second point will be (x, 3.5).
<h3>What is coordinate geometry?</h3>
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The point is given as (3, 3.5).
Then name a second point so that the two points form a horizontal segment.
For the horizontal segment, the value of the ordinate will not change.
Let x be the abscissa.
Then the point will be given as (x, 3.5).
