Answer:
8.2
Step-by-step explanation:
-7.2 to -7.2 is 0
-9.3 to -1.1 is 8.2
Pythagorean theorem is a^2+b^2=c^2
0^2=0
8.2^2=67.24
0+67.24=0
√67.24=8.2
The distance between the to points is 8.2
Firts, Let

be the repeated decimal that we are trying to convert , so

equation (1)
Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:

(2)
Subtract equation (1) from equation (2):


Solve for


We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>
