Step One
Convert miles to km. The conversion constant is 1.6 km / mile
19 miles * 1.6 km/mile = 30.4 km Notice the miles cancel.
Step Two
Convert the gallons to liters.
This is the sticky part of the question. Where are you? The conversion factor is different in Canada or Great Britain that it is in the United States. If you are not in the US use 4.5 otherwise 1 gallon has 3.78 L in it if it is a US gallon
30.4 km / 3.78 L = 8.04 km per Liter using a US Gallon.
30.4 km / 4.5 L = 6.76 km / Liter using an Imperial Gallon which not used in either Canada or Great Britain. Imperial Gallons are obsolete.

Answer:
- 7227
- 6649
Step-by-step explanation:
Let x represent the enrollment the first year. Then x(1 -8%) = 0.92x represents the enrollment the second year. The total for the two years is ...
x + 0.92x = 13,876
x = 13,876/1.92 = 7227.083 ≈ 7227 . . . . students the first year
13876 -7227 = 6649 . . . . students the second year

Answer:
Step-by-step explanation:
If arccos (√3 / 2) = β, then cos β = adjacent side / hypotenuse = √3 / 2. This tells us immediately that the adjacent side length is √3 and the hypotenuse is 2. Via the Pythagorean Theorem, we know that the third side is 1.
This information rules out the 1st and 3rd answer choices.
Because cos 30° = adj / hyp = √3 / 2, we can conclude that the correct answer is the 4th one: 30°, 60°, 90°
Answer:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
\begin{gathered}a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288\end{gathered}an=arn−1, where a=initial term, r=common ratio, n=term numberan=9(2n−1)a6=9(25)a6=288
