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

A bank loaned out $19,500, part of it at the rate of 11% annual interest, and the rest at 7% annual interest. The total interest
Morgarella [4.7K]

The amount loaned at the interest rate of 11% is $3000.

The amount loaned at the interest rate of 7% is $16,500

<h3>What are the linear equations that represent the question?
a + b = 19500 equation 1</h3>

0.11a + 0.07b = 1485 equation 2

Where:

a = amount loaned at the interest rate of 11%

b = = amount loaned at the interest rate of 7%

<h3>How much was loaned at 11% and 7%</h3>

In order to determine how much was loaned at 7%, take the following steps:

Multiply equation 1 by 0.11:

.11a + 0.11b = 2145 equation 3

Subtract equation 2 from equation 3:

0.04b = 660

Divide both sides by 0.04:

b = 16,500

Subtract 16,500 from 19,500 :

19,500 - 16,500 = $3000

From 11 positive integer scores on a 10-point quiz, the mean is exactly 8, the median is exactly 8, and the mode is exactly 7. f
Zanzabum
<span>3 perfect scores of 10 There can't be 5x10 because the mode (the commonest score) is 7. Hence if there are 5x10 there must be 6 x7, but the median (the middle score) is 8 and this would make at least 12 scores which is impossible. There can't be 4x10. If there were 4 x10 there would be 5x7 (7=mode), 1x8(median) + either another 8 or 9. Assuming the best case scenario (2 x8). The total of the 11 scores = 91. They should add up to 88 (mean = 8, (11x8=88) If there are 3x10, there must be at least 4x7(mode =7), 3more 8+(median = 8), and 1 x less than 7. 3x10, 3x8, 4x7 and 1x6 fits the bill. Mean= (30+24+28+6)/11 = 88/11 = 8 OK Median is the sixth number in the series = 8 OK The mode is the commonest number. Mode = 7 OK</span>
