None are correct because angle A is 40 degrees
Repeating decimals are rational....but they have to be repeating.
The only one that is not repeating is : D .131131113...now if the last 3 digits would have been 131 instead of 113, then it would have been rational.
Answer:
The number of vertices are 
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
so

substitute the values and solve for V




It's b. Group all the pounds together and all the volumes together. Small packages weigh 30 lbs (30x), lg pkgs weight 65 lbs (65y) and together they weigh at most 3800 lbs. So 30x + 65y <= 3800 (they divided each of those terms by 5 to get 6x + 13y <= 760). Next take the volumes: small pkgs have a volume of 4 ft^3 (4x) and lg pkgs have a volume of 9 ft^3 (9y) and together they are no more than 400 ft^3. So 4x + 9y <= 400. It's b.
