Taylor took 6 hours to drive home from college for Thanksgiving break, a total distance of 290 miles.
vredina [299]

Answer: at 50 mph, she drove for 4 hours.

at 45 mph, she drove for 2 hours.

Step-by-step explanation:

Let t represent the time that she spent driving at 50 miles per hour.

Taylor took 6 hours to drive home from college for Thanksgiving break. This means that the time that she spent driving at 45 miles per hour is (6 - t) hours.

Distance = speed × time

Distance covered while driving 50 miles per hour is

50t

Distance covered while driving 45 miles per hour is

45(6 - t)

Since the total distance that she drove is 290 miles, it means that

50t + 45(6 - t) = 290

50t + 270 - 45t = 290

50t - 45t = 290 - 270

5t = 20

t = 20/5 = 4

At 45 miles per hour, she drove at

6 - 4 = 2 hours

An advertisement for a circular rug says that the rug has a diameter of 6 feet. Find the relative error of this measurement
Aleonysh [2.5K]

Answer:

1. 8.3%

Step-by-step explanation:

Relative error = absolute error/expected measurement

The expected measurement is given as 6 ft.

Now, the absolute error is usually equal to half of a unit of the measure.

This means the absolute error in this case is ½ × 1 = 0.5 ft

Thus, the exact measurement will be;

6 ± 0.5

Thus;

Relative error = 0.5/6

Relative error = 0.083

Expressing it in percentage gives 8.3%
