Riding the bus, roger uses 1/3 of his money for bus fare. what is the fraction of his money expressed as a decimal? a. 0.3 (with a line above the 3) b. 0.6 (with a line above the 6) c. 0.8 (with a line above the 8) d. 1.5 (with a line above the 5) i cant figure this out.

A. 0.3 (With a line above the 3) ()

Step-by-step explanation:

The part of money used for the bus fare =

Upon division the value,

As this no. is a rational number with recurring decimal. It means that the number after the decimal repeats up to infinity.

Such recurring decimal numbers are represented with a bar or line over the recurring digits.

Thus the given number is represented as .

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

(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.
