Answer:
9m
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2 where s is the side length
We know the surface area is 486 and the side length is z
486 = 6z^2
Divide each side by 6
486/6 = 6z^2/6
81 = z^2
Take the square root of each side
sqrt(81) = sqrt(z^2)
9 = z
Each side has a length of 9m

Answer:
<em> of Steph's annual income is from her full-time job.</em>
Step-by-step explanation:
Suppose, Steph's annual income is
Given that, 80% of Steph's annual income is from her full-time job.
So, <u>the amount of income from her full time job will be</u>:
Now, for finding the income from her full time job as a fraction of Steph's annual income, we just <u>need to divide "income from full time job" by "total annual income"</u>.
So, the fraction will be:
That means, of Steph's annual income is from her full-time job.
