To simplify the expression \( \frac{7}{(-5.3^0)} + 4.9 \), we start by evaluating \( -5.3^0 \).
First, any number raised to the power of 0 is equal to 1, so: \[ -5.3^0 = 1 \]
Now, we can substitute this back into the expression: \[ \frac{7}{1} + 4.9 \]
This simplifies to: \[ 7 + 4.9 \]
Finally, adding these two numbers together gives: \[ 7 + 4.9 = 11.9 \]
Thus, the answer is: \[ \boxed{11.9} \]
