Answer:
Correct answer: Third answer a₉ = 196,608
Step-by-step explanation:
We will use the results of the previous two questions of the same geometric series
a₁ = 3 and q = 4
aₙ = 3 · 4⁽ⁿ ⁻ ¹⁾
a₉ = 3 · 4⁽⁹ ⁻ ¹⁾ = 3 · 4⁸ = 3 · 65,536 = 196,608
a₉ = 196,608

Answer: 2.44 inches
Step-by-step explanation:
Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.
The number of inches that are between the two cities will be represented by x. Therefore,
1/x = 45/110
Cross multiply
45x = 110
x = 110/45
x = 2.44 inches
The Distance between the two cities on the map is 2.44 inches
