Suppose we were to test the following argument to determine whether or not it is deductively valid (a case of semantic entailment): \neg \neg p, \neg \neg q\rightarrow r\models \neg (p\vee r) ¬¬p,¬¬q→r⊨¬(p∨r)¬¬p,¬¬q→r⊨¬(p∨r). the first step of using the truth-tree test is to setup the tree into what is called the ``stack''. which one of the following formulas would not be in the initial stack:

Michelle and julie work at a catering company. they need to bake 264 cookies for a birthday party that starts in a little over an hour and a half. each tube of cookie dough claims to make 36 cookies, but michelle eats about 1/5 of every tube and julie makes cookies that are 1.5 times as large as the recommended cookie size.it takes about 8 minutes to bake a container of cookies, but since julie's cookies are larger, they take 12 minutes to bake. a. how many tubes should each girl plan to bake? how long does each girl use the oven? b. explain your solution process what did you make? c. what assumptions did you make?
