7 0

The digit 3 is in the millions place value, hence it is worth three million, not three thousand.
Therefore, 3,000,146 should be read as three million, one hundred and forty-six, and NOT three thousand, one hundred and forty-six.
Hope this answer helps you! If it did, please mark it as the brainiest! I would really appreciate it! :)

A line segment is divided in two segments, such that the ratio of the long segment to the short segment is equivalent to the go

vova2212 [387]

Answer:

9.271 inches.

Step-by-step explanation:

Let AC be the length of original line segment and point B divides it into two segments such that AB is longer and BC is smaller segment.

$AB+BC=AC=15$

We can describe the golden ratio as:

$\frac{AB}{BC}=\frac{AC}{AB}=1.618$

$\frac{AC}{AB}=1.618$

$\frac{15}{AB}=1.618$

$\frac{15}{1.618}=AB$

$9.270704=AB$

$AB=9.271$

We can verify our answer as:

$AB+BC=15$

$9.271+BC=15$

$9.271-9.271+BC=15-9.271$

$BC=5.729$

$\frac{AB}{BC}=1.618$

$\frac{9.271}{5.729}=1.618$

$1.618=1.618$

Hence proved.

Therefore, the length of the longer side would be 9.271 inches.

Rathan thinks all factors of even numbers are even. Which explains whether Rathan is correct?

Nesterboy [21]

In order to prove Rathan wrong, we only need one counterexample. Take the number 6. 6 is even, but it has the odd number 3 as a factor, so clearly, not all factors of even numbers are even.
