Answer:
$1.12
Step-by-step explanation:
One way to solve this problem is through an algebraic equation. Set up the equation like this,
. This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.
So, to solve first subtract 3.28 from 10, this gives you 6.72. Then, divide both sides by 6. This equals 1.12, which is the cost of each key.
Answer:
If multiples are allowed (like "10 plain, two chocolate"), then for each of 12 donuts there are 21 possibilities.
That is 21 x 21 x 21 .... x 21 (12 terms in all) = 21^12
Step-by-step explanation:
No it can never be greater than the largest number in the set because an average (or a mean) is the "<span> number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number." c:</span>

Answer:
2.507* 10^-4
Step-by-step explanation:
0.0002507
We need to have one number to the left of the decimal
We move the decimal 4 places to the right
Since we moved the decimal to the right, the exponent on the power of 10 is negative
2.507* 10^-4
