Deijah has $6.25.
Now, this 6.25 is comprised of 0.05s and 0.25s.
We know that there are 12 0.25s.
We now want to know how many remaining 0.05s there are.
Again, we know that the number of 0.05s he has, which is 12, multiplied by 0.05, plus the number of 0.25s he has, multiplied by 0.25, equals 6.25.
Thus, the answer is A, 0.25 x 12 + 0.05 x n = 6.25.
Answer:
6
Step-by-step explanation:
The overbar means the digit repeats indefinitely. The repeating decimal 0.333... is equivalent to 1/3, so this is the simple addition ...
3 2/3 + 2 1/3 = 5 3/3 = 6
_____
<em>Comment on the repeating decimal</em>
1/3 = 0.3333... repeating is one of the first decimal equivalents you learn.
__
If you're into repeating decimals. you may have learned how to convert them to fractions:
x = 0.3333... repeating . . . . . . . give a name to the value
10x = 3.3333... repeating . . . . . multiply by 10^p where p is the number of digits in the repeating pattern
10x - x = 3.3333... - 0.3333... = 3 . . . . . subtract: the repeating portions cancel
9x = 3 . . . . . . . . . .simplify
x = 3/9 = 1/3 . . . . .divide by the x-coefficient; simplify

Step-by-step explanation:
What is a regular tessellation?
A regular tessellation is a pattern made by repeating a regular polygon. In simpler words regular tessellations are made up entirely of congruent regular polygons all meeting vertex to vertex.
How many regular tessellation are possible?
There are only 3 regular tessellation.
1. Triangle
2. Square
3. Hexagon
Why aren't there infinitely many regular tessellations?
Not more than 3 regular tessellations are possible because the sums of the interior angles are either greater than or less than 360 degrees....
