13 hours
Step-by-step explanation:
8:00 plus 4 is twelve ( 12 o'clock )
then you have 9hrs left.
( 4+9=13 )
The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is:
<u><em>Explanation</em></u>
Number of right answers is and number of wrong answers is
Olga earns 12 points for each right answer and loses 4 points for each wrong answer.
So, total points earned for right answers
and total points lost for wrong answers
That means, <u>her score will be</u>: points.
In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......
The radius of the circle is 24
1. vertical angle theorem and triangle angle sum theorem
2. The sum of the interior angles of a triangle = 180
so < x = 180 - (70 + 30) = 180 - 100 = 80
and < y is a vertical angle to < x...and vertical angles are equal..
so < y = 80
