Answer:

4t+6

Step-by-step explanation:

To find the perimeter of the rectangle you add the length of the sides.

Perimeter= t+ t+ t+ 3+ t+ 3= 4t+6

Perimeter=2(t)+ 2(t+3)= 2t+ 2t+ 6= 4t+6

A. The number of fabric-pattern-color combinations is 4 * 13 * 9 = 468

B. P(1st choice) = no of novels / total books = 3/6 = 1/2
    P(2nd choice) = no of remaining novels/ total remaining books = 2/5
    P(both novels) = 1/2 * 2/5 = 1/5 (without replacement assumed)

C. P(1st choice) = no of biographies / total books = 2/6 = 1/3
    P(2nd choice) = no of remaining biographies/ total remaining books = 1/5
    P(both biographies) = 1/3 * 1/5 = 1/15 (without replacement assumed)

D. P(1st choice) = no of history books / total books = 1/6
    P(2nd choice) = no of novels/ total remaining books = 3/5
    P(a history, then a novel) = 1/6 * 3/5 = 1/10 (without replacement assumed)

A taxi ride costs p40.00 for the first 500 meters and each additional 300 meters or a fraction there of adds p3.50 to the fare.u

Zarrin [17]

The function which represents the taxi fare in terms of distance d in meter is f(d) = 3.50 × $\frac{d-500}{300}$ + 40 .

According to the question,

For first 500 meters cost is 40.00 and For each additional 300 meters cost is 3.50 .

Let, the total distance of taxi ride = d meters

Now, representing the equation of taxi fare in terms of distance when distance is less than 500

taxi fare = 3.50 × $\frac{d-500}{300}$ + 40

∴ f(d) = 3.50 × $\frac{d-500}{300}$ + 40
