9 mph because if it was 4/5 miles in 1/10 of an hour you just multiply it by 10 to get an hour and if you multiply 4/5 x 10 equals 40/5. simplified it is 9
        
                    
             
        
        
        
The possible side length combinations would be 1 and 39 or 3 and 13.
1 and 39: the perimeter of these two would be 80.
3 and 13: the perimeter of these two would be 32.
The answer is 32. 
        
             
        
        
        
4⅚ ≥ x; subtract fifty-eight from both sides, divide by -12 from both sides, and you will have your answer.
NOTE: This is where you reverse your inequality symbol [dividing or multiplying by a negative].

Answer:
   (b)  Ingrid’s claim is correct, but her steps are incorrect
Step-by-step explanation:
As nearly as we can tell from the problem statement, Ingrid's table looks like the one attache. We have highlighted the incorrect steps.
Step 3 should read ...
   0·cos(y) -(-1)·sin(y) = sin(y) . . . . . . . . . sin(-π/2) = -1
Step 4 should read ...
   0 + sin(y) = sin(y)
So, Ingrid's conclusion is correct, but her steps are incorrect.
 
        
             
        
        
        
Answer:
11
Step-by-step explanation:
5x° + 35° = 90°
(complementary angles) 
5x° = 90° - 35°
5x° = 55°
x = 55/5
x = 11
