Andrew is correct, because 1/2 could mean any fraction that’s equal to 1/2. 5/10 could also be 1/2. 2/4 could also be 1/2. 8/16 could also be 1/2. They are equivalent, but 1/2 could be a different amount.

How many 2 digit whole numbers are increased by 18 when they're digits are reversed
Anika [276]

This can be calculated easily.

As any two digit number can be written in the following form:

N= 10x +y

If we reverse the number now, it would become:

N' = 10y + x

So if we subtract one from the other, we should obtain 18 ( as mentioned in the question ).

N-N'= 18

=> x-y = 2

Thus, any number whose digits differ by two would be an aswer to the question.

The only numbers which satisfy this are : 13,24,35,46,57,68,79

But this would not be true for any 3 or more digit number.

What is the<br> the distance between a point at (-3,4) and a point at (2,-5)
zaharov [31]
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

What is the distance between a point at (-3,4) and a point at (2,-5) ?

<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

Let the two points be A and B .

And, let the distance be P .

Now, the distance P between the point A (-3,4) and the point B (2,-5) is

\bf P \: = \sqrt{(-3 \: - \: 2)^2 \: + \: (4 \: + \: 5)^2}

\implies \bf P \: = \sqrt{(-5)^2 \: + \: (9)^2}

\implies \bf P \: = \sqrt{25 \: + \: 81}

\implies \bf P \: = \sqrt{106}

\implies \bf P \: = \: 10.3

<h3>The distance between a point at (-3,4) and a point at (2,-5) is <u>1</u><u>0</u><u>.</u><u>3</u> . [Answer]</h3>
