Answer:
The correct option is G.Hope this help!!
<span>The answer is 360.
f(x) varies directly with x^2 and f(2) = 40. What does that mean?</span>
<span>It means this f(x) = k* x^2. We need to find k.
For x=2, f(x) = 40, this means k* x^2 = 40. BUT, x=2.
This means p* 2^2 = 40. => k = 40 / 4 = 10.
We just found what f(x) is: f(x) = 10x^2.
Now, what is the value of f(6)?
Just replace the value of k by 10. => f(6) = 10* 6^2 = 10*36 = 360</span>
The volume of the box is
.. V = (90 cm)*(45 cm)*(45 cm) = 182,250 cm³
The empty 15% of the volume is then
.. empty volume = 0.15*182,250 cm³ = 27,337.5 cm³
This will require
.. (empty volume)/(volume / bag) = 27,337.5 cm³ / (28,316 cm³/bag) ≈ 0.97 bag
to fill.
Selection A. 1 bag is appropriate.
