Answer:

The answer should be 185 tiles.

Step-by-step explanation:

What we're dealing with here is a percentage conversion.

65%=120 tiles

We know that the total number of tiles will equal 100%

Divide both sides of the equation by 65 to get 1%=1.84 tiles

Multiply this equation by 100 to get 100%=184.6 tiles.

Since I assume we are looking for a whole number of tiles, you will want to round up to the next full tile. Hence, 185 tiles.

Answer: 5,260

Step-by-step explanation:

So the question here is 45% of WHAT number (x) = 2,367

Setup as a fraction

45/100 = 2,367/X

Cross multiply

45X=236,700

Divide 45X by 45 to get X alone

Divide the other side too bc what you do to one side, you have to do to the other.

236,700/45=

5,260

Check your answer

45/100=2367/5260

The height of a person and the person age is a linear relationship or not

Tom [10]

It is not because the term is used to describe the differences of a variable and a constant. Both of height and age are variables.

Use logical equivalences (not a truth table) to reduce p → (q − p) to a tautology t. In other words, you should transform p → (q

schepotkina [342]

Answer:

The statement $p\rightarrow (q\rightarrow p)$ is a tautology.

$p\rightarrow (q\rightarrow p)\equiv \lnot p\lor (q\rightarrow p) \equiv \lnot p\lor (\lnot q\lor p) \equiv (p\lor \lnot p) \lor \lnot q \equiv T \lor \lnot q \equiv T$

Step-by-step explanation:

We have the following statement:

$p\rightarrow (q\rightarrow p)$

To reduce the statement to a tautology we need to use the table of logical equivalences as follows:

$p\rightarrow (q\rightarrow p)\equiv$

$\equiv \lnot p\lor (q\rightarrow p)$ by the the logical equivalence involving conditional statement.

$\equiv \lnot p\lor (\lnot q\lor p)$ by the the logical equivalence involving conditional statement.

$\equiv (p\lor \lnot p) \lor \lnot q$ by the Associative law.

$\equiv T \lor \lnot q$ by the Negation law.

$\equiv T$ by the Domination law.
