Answer: The decimal 0.88888.... represented by the fraction 
Step-by-step explanation:
Since we have given that
0.888888....
So, Let x = 0.88888....=
-----(1)
Now, multiply by 10 on both sides, we get that

Now, Subtracting (1) from (2), we get that

Hence, the decimal 0.88888.... represented by the fraction 
The sum of 2 complementary angles equals 90 degrees.
If angle 1 and 2 are complementary and angle 1 and 3 are also complementary than angle 2 would have to be the same as angle 3.
The answer would be true.
Answer:

Step-by-step explanation:
We start off with 3.2n + 13.3 = 26.1.
We need to get n by itself.
Subtract 13.3 from both sides.


We end up with: 
Divide 3.2 on both sides to get n by itself.

I^5 + i^6 + i^7 + i^8
i^11 + i^15
i^26
therefore your answer is:
i^26
