The perimeter is 96 ft

Step-by-step explanation:

Step 1:  Add the given sides

9 + 9 + 9 + 9 + 9 + 9 + 30 + (30 - 9 - 9)

84 + (12)

96

(30 - 9 - 9) gives us the opposite side of 30 ft

 The perimeter is 96 ft

∞ this is your sign

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
