Chaz is a 79.2 pound dog that was just adopted. Based on his foster home his daily energy intake is 1,840 kcal. Chaz’s new owner
zimovet [89]

Answer:

option (c)5 and  \frac{\textup{1}}{\textup{4}}  cups

Step-by-step explanation:

Given:

Weight of Chaz = 79.2 pounds

Daily energy intake requirement = 1,840 kcal

Energy present in different brand food = 3,523 kcal/kg

Therefore,

the amount of food required = \frac{\textup{Daily energy intake requirement}}{\textup{Energy present in different brand food}}

or

the amount of food required = \frac{\textup{1,840}}{\textup{3,523}}

or

the amount of food required = 0.52228 kg

also,

1 kg = 1000 grams

therefore,

the amount of food required = 0.52228 × 1000 = 522.28 grams

now,

A cup of food weighs 100 grams

hence,

the number of cups required = \frac{\textup{the amount of food required }}{\textup{Amount of food per cup}}

or

the number of cups required = \frac{\textup{522.28}}{\textup{100}}

or

the number of cups required = 5.2228 ≈ 5 and \frac{\textup{1}}{\textup{4}}  cups

Hence, the correct answer is option (c)

Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~PAP Q~QvQ
NNADVOKAT [17]

Answer:

The statement \lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q is a tautology.

Step-by-step explanation:

We have the following statement \lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The simple statements from the statement given are:

\lnot P, \lnot Q, \lnot P \land P, \lnot P \land P \rightarrow Q, and \lnot Q \lor Q with these you can construct the following truth table.

A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.

The last column contains only true values. Therefore, the statement is a tautology.
