Answer:

6 hours

You are given following data:

15 logs - 10 hours,

9 logs - x hours.

Use proportion to determine unknown value of x:

\dfrac{15}{9}=\dfrac{10}{x}.

Then

15\cdot x=9\cdot 10,\\ \\x=\dfrac{90}{15}=6\ hours.

Answer: 6 hours

How do you evaluate the expression |4/13|
Anuta_ua [19.1K]
Hi there!

First, you need to find the quotient of 4 and 13, obviously.

4/13 is equal to roughly 0.308.

Those grouping symbols around it tell you that you need to find the absolute value.

Absolute value is how far away a number is from 0 on a number line. 3, for example has a absolute value of 3, and -6 has an absolute value of 6.

So, the absolute value of 4/13 is about 0.308.

Hope this helps.  :)
