Construct a truth table for the disjunction A OR B OR C.

Disjunction is a logical operation which forms compound propositions which are false only if all statements (disjuncts) are false. If at least on statement is true the result of disjunction is true. For three statements A, B and C the following table shows how it works (1 means true, 0 means false):

\begin{array}{cccc}   A & B & C & A\vee B\vee C \\   1 & 1 & 1 & 1 \\   1 & 1 & 0 & 1 \\   1 & 0 & 1 & 1 \\   1 & 0 & 0 & 1 \\   0 & 1 & 1 & 1 \\   0 & 1 & 0 & 1 \\   0 & 0 & 1 & 1 \\   0 & 0 & 0 & 0  \end{array}

Gina is buying juice, she needs 30 servings.At the store she can get 30 individual boxes for $21.99, or she can get 1/2 gallon c
Mila [183]
It is better for Gina to buy the individual boxes for $21.99 rather than to buy Each carton for $3.99

To find the total amount for the 1/2 gallons, you 1st round $3.99 to $4 then you multiply 4 by 6 to get 24. This means she pays a total of $24 for the 1/2 gallons.
The reason that you multiply 4 by 6 is because you'd need 6 1/2 gallons to make 30 servings

The area of a rectangle that has a length of 10 and a width of w.
alexdok [17]

Answer:

B

Step-by-step explanation:

To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.

If \: x + y + z = 0 \: then \: show \: that \: {x}^{3} + {y}^{3 } + {z}^{3} =3xy<br>​
tankabanditka [31]

Answer:

Given

x+y+z=0

⟹x+y=−z

Cubing on both sides

(x+y) 3 =(−z) 3

⟹x 3 +y 3 +3x 2y+3xy 2 =−z 3

⟹x 3 +y 3 +3xy(x+y)=−z 3

⟹x 3+y 3+3xy(−z)=−z 3

⟹x 3 +y 3−3xyz=−z 3

⟹x 3 +y 3 +z 3 =3xyz

Step-by-step explanation:

Hope it is helpful.....
