Kellie is given the following information:

Murljashka [212]

Answer:

She used inductive reasoning. (False)

She used the law of detachment. (True)

Her conclusion is valid. (True)

The statements can be represented as "if p, then q and if q, then r." (False)

Her conclusion is true. (True)

Step-by-step explanation:

p = Two lines are perpendicular

q = They intersect at Right angles.

Given: A and B are perpendicular

Conclusion: A and B intersect at right angle.

According to the law of detachment, There are two premises (statements that are accepted as true) and a conclusion. They must follow the pattern as shown below.

Statement 1: If p, then q.

Statement 2: p

Conclusion: q

In our case the pattern is followed. The truth of the premises logically guarantees the truth of the conclusion. So her conclusion is true and valid.

How do i turn reapeating decimals into fractions?

inysia [295]

Easy example that shows $0.999\ldots=1$ :

Let $x=0.999\ldots=0.\overline9$ .

Then $10x=9.999\ldots=9.\overline9$ .

So $10x-x=9.\overline9-0.\overline9$ , or $9x=9$ , and so $x=1$ .

The basic idea is to find the period of the repeating decimal, move the $n$ digits belonging to one period over to the left of the decimal point by multiplying by $10^n$ , then subtract the original repeating decimal from this new number, and finally divide by $10^n-1$ .

A slightly more complicated example:

Let $x=0.142857142857142857\ldots=0.\overline{142857}$ .

Then $10^6x=142857.\overline{142857}$ .

Then $10^6x-x=142857.\overline{142857}-0.\overline{142857}$ , or

$999999x=142857\implies x=\dfrac{142857}{999999}=\dfrac17$

Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg,

pentagon [3]

Let the bushels of wheat is b and weight of the wheat is w.

We can say that more the bushels of wheat more will be the weight of the wheat.

Hence, the quantities vary directly.

Therefore, we have

$b=kw$ , where k is the constant of variation.
