Solution:
Duration of time for which a contestant have to speak = 5 minutes (300 Seconds)
Point lost by a contestant for over-speaking that is for more than 5 minutes for each second = 3 points
Point lost by a contestant for speaking less than 5 minutes on each second = 3 points
So, the expression which can determine ,the number of points a contestant loses if she speaks for x seconds.
⇒Number of points a contestant loses if she speaks for x seconds=
For, example if a contestant speaks for 290 seconds,Points lost by contestant =
=3 × 10= 30 Points
If a contestant speaks for 305 seconds,Points lost by contestant =
=3 × 5= 15 Points
Option (A)=
is right choice describing above situation.
x+14= 21
move +14 to the other side
sign changes from +14 to -14
need to get x by itself
x+14-14= 21-14
x=21-14
Answer:
x= 7
The answer choice which represents a pair of complementary angles in the task content is; angles DEH and DEJ.
<h3>Which pair of angles represent complementary angles?</h3>
It follows from the concept of angle geometry that two or more angles are said to be complementary when the sum of their measures is 90°.
It follows from the task content therefore that since, DEJ = 90° and the sum of the measures of angles DEH and DEJ amounts to 90°.
Hence, the pair of angles are complementary.
