Others have given you alternatives. For an explanation, as you've written the code the condition of the first if statement must be satisfied for MATLAB to even evaluate the condition of the second if statement. If the first if statement's condition is not satisifed, MATLAB continues execution after the end statement associated with that if statement.
Is there any number that is simultaneously greater than or equal to 90 (from the first part of the first if condition) and less than or equal to 89 (the first part of the second if condition)?

prompt = ' enter a value between 0 and 100 ' ;
x = input(prompt) ;
if x >= 90 && x <= 100
disp (' Grade is A ');
elseif x <= 89 && x >= 80
disp (' Grade is B ');
end
OR
prompt = ' enter a value between 0 and 100 ' ;
x = input(prompt) ;
if x >= 90 && x <= 100
disp (' Grade is A ');
end
if x <= 89 && x >= 80
disp (' Grade is B ');
end

Use elseif:
prompt = ' enter a value between 0 and 100 ' ;
x = input(prompt) ;
if x >= 90 && x <= 100
disp (' Grade is A ');
elseif x <= 89 && x >= 80
disp (' Grade is B ');
end
