Brisbane and Rockville are 10 in apart on a map that has a scale of 1 in : 17 mi.
How far apart are the real cities?


170 miles apart

Step-by-step explanation:

1 inch is 17 miles, so 10 inches will represent 170 miles.

x stands for inches, y for miles, and * for multiplication.

First we multiply both sides by 10, then we simplify.

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
