386 divided by 20 is 19.3 so Greg averaged 19.3 miles per gallon.
It triples in size every 4 days. In 16 days it will be 3 * 3 * 3 * 3 times bigger.
3 * 3 * 3 * 3 = 81
Therefore, after 16 days, the colony will contain (81 * 150) or 12,150 microorganisms.
Answer:
5/4
Step-by-step explanation:
Using coordinates (10,0) and (90,100)
Slope m = (y2-y1)/(x2-x1)
m = (100 - 0)/(90 - 10) = 100/80 = 10/8 = 5/4
30:6 is an equivalent ratio. Anymore and you would have a decimal.
