The bacteria population doubles in 4 hours.
So, in 1 hour it increases by x/4 of its population, where x is population.
So in 1/2 hours or 30 minutes, the increase will be x/4 × 1/2 = x/8
=> if we start with 4000 bacterias, population increase after 30 minutes is 4000× 1/8 = 500
So, 500 more bacterias were added
Total bacterias = 4000+500 = 4500 bacterias
Answer: Store B
Step-by-step explanation:
180 / 3 = 60. 180 - 60= $120. Store A cost is $120.
110 * 0.9 = $99. Store B's cost is $99.
Answer:
- 6 units left and 4 up (if figure K translated)
- 6 units right and 4 units down (if figure J translated)
Step-by-step explanation:
<em>It is not clear which of the figures is translated.</em>
<em>Assume it is figure K.</em>
Use one of the points and compare the corresponding point.
<u>If you take bottom-left point, then the difference is coordinates is:</u>
- -7 - (-1) = -6, this is translation left by 6 units (or right if the figure J is translated)
- 2 - (-2) = 4, this is translation up by 4 units (or down if the figure J is translated)
<u>So the answer is </u>
- 6 units left and 4 up or, (figure K translated)
- 6 units right and 4 units down (figure J translated)
