You're writing a book about a $3,030 bike race across the United States. You wonder about a title, and how many pedal strokes it takes to finish the race. Assuming a pedal stroke is about 16 ft on average which of the following would be the best title?

I hope that helped.

Step-by-step explanation:

We have that a mile is equal to 5280 feet. Hence the whole distance is 15.998.400 feet in distance. Since every 16 feet we have one stroke, we have to divide the distance by 16 to get the number of strokes. The result is 999.900 strokes. Hence, if one wants to be accurate, the correct title is "999.900 pedal strokes". For poeticness though, maybe the best title is "1 million pedal strokes".

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
