Step-by-step explanation:
This question was linked from another one regarding the lengths of the cubes, you can find it here: brainly.com/question/22396279
That question gave you the ratio of the lengths, which is . Now in geometry, a general rule about solids is that if they are similar, the ratio of their volumes is the cube of the ratio of their edges. In a cube's case, every single cube known to mankind is similar as all the edges are the same length.
So the ratio of volumes would be , which can be simplified as
.

Answer:
Step-by-step explanation:
we have given x'=(24-16)x=8x
x' denotes the differenation
differentiation is performed with respect to t
by variable separable method we can write
on integrating both side
(property of log )
so the solution for x will be
To answer this question we will use the following formula for compounded monthly interest:
where A₀ is the initial amount, r is the annual interest as a decimal number and 12 is the number of years.
Notice that:
Therefore, substituting t=42, r=0.02, and A₀=120000 we get:
Simplifying the above result we get:
Answer: $277,769.75.
