Since she ran 6 times to complete a mile, each lap should be 1/6 of a mile. To run 5/6, she must run 5 laps. Your final answer should be 5. Hope this helps!
To answer this item, we are to use the concept of combination. The equation is as follows,
nCr = (n!)/((r!)(n - r))!
Substituting the known values in the equation,
3C2 = 3!/(2!)(3-2)! = 3
Hence, the answer to this item is 3.
<em>ANSWER: 3</em>
Imagine, at the first day you have only one penny. Then tomorrow you have 2 pennies, next day you have 4 (2x2), next day you have 8 (4x2), next day you have 16 (8x2).... and so forth.
It looks like geometric sequence isn't it? (the ratio between the number of pennies that you have from the 2nd day and the 1st day is 2)
So, by using geometric sequence theorem we can total those pennies until day-27
S (total pennies at day-27) = (1)(2^27-1) / 2-1 = 2^26 pennies
So, you have 2^26 pennies.. a big number of pennies huh?=))
{The formula is: S = a( r^n-1) / r-1
Where:
a= the number of pennies that you've got at the 1st day
n= number of days you spent to collect those pennies)
r= the ratio of the number of pennies}
Answer:
Rational because it is a decimal that can be seen as a fraction.

Answer:
0.052 acre/min
Step-by-step explanation:
6 1/4 acres / 2 hours times the conversion factor (1 hr / 60 min) comes out to:
