Answer:
6 for $24.96
Step-by-step explanation:
$5.90 * 3 = $17.70
Therefore 4 books would be $17.70 because you get one for free
$24.96/6 = $4.16
Therefore if you got 4 books it would be $16.64
So, buying 6 books would be cheaper.
Answer:From the attached graphic, Half-life = ln (.5) / k
Half-life =.693147 / 0.1142
= 6.0695884413 days
Step-by-step explanation:The value of "k" should be negative and should have units associated with it.
Angle 2 and 1 are supplementary. Supplementary angles are out of 180°
If angle 2 is equal to 118°, then
180 - 118 = angle 1
∠1 = 62°
