The Absolute Value of a number is "the magnitude of a real number without regard to its sign". So the Absoulute Value of 1/2 is |1/2|
The smallest the absolute value will ever be is zero so the left side won't ever be smaller than -2 so won't ever be less than -3.
D. No solution
Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
= 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
= 8.57 minutes
≈ 9 minutes
Answer:
x=45°
Step-by-step explanation:
A straight line is 180°. Since we have a 90° angle, and CD is a straight line, 90/2=45
45° is the answer.
