C=.41+.26(z-1) solve for z

Ksivusya [100]

$c=0.41+0.26(z-1) \\0.26(z-1)=c-0.41 \\z-1=(c-0.41)/0.26 \\\boxed{z=(c-0.41)/0.26+1}$

Hope this helps.

Find the length of molding needed for a 10'5" by 9'8" floor

disa [49]

Perimeter = 2(length + width)
p = 2(10'5" + 9'8")
p = 2(19'13")
p = 38'26"

26" = 2'4"

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>
