A pathway made of slate tiles measures 513 yards long. A tile measuring 2 feet is added to the end of the pathway. What is the total length of the pathway now? 513 ft 1023 ft 18 ft 22 ft

The total length of the pathway now is 1,541 ft

Step-by-step explanation:

To calculate the length of the pathway now, what we need to do is to have a consistency in units.

Thus, we need to convert the 513 yards to ft

Mathematically 1 yard = 3 feet

Thus 513 yards will be = 513 * 3 = 1,539 ft

Thus the total length of the pathway now will be 1539 ft + 2 ft = 1541 ft

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
