Answer:

You could arrange them 3 different ways <em>at once</em>.

Step-by-step explanation:

You have 12 different cars, but only 4 can be shown at once.

Divide 12 by 4, and you'll get 3.

Therefore, if you wanted to show them all at once, you could make 3 different displays.

what is the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube

Dmitrij [34]

Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then

$\frac{99}{2} (2x+98)=p^3 \\ \\ 99x+4,851=p^3\\ \\ \Rightarrow x=\frac{p^3-4,851}{99}$

By substitution, we have that $p=33$ and $x=314$ .

Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>
