s = 2pirh

s ÷ 2 = pirh

s ÷ 2pi = rh

s ÷ 2pih = r

You just need to divide both sides by $2\pi h$ : the equation becomes

$s = 2\pi rh \iff \dfrac{s}{2\pi h}=\dfrac{2\pi rh}{2 \pi h} \iff \dfrac{s}{2\pi h}=r$

balandron [24]

Answer:

1.875 or $1\frac{7}{8}$ cups of pretzel

Step-by-step explanation:

The number of cups needed is equivalent to the probability of pretzel in the mix times the number of cups in the mix.

-The probability of pretzel is :

$P(pretzel)=\frac{0.2}{0.25+0.25+1.5}\\\\=0.125$

We multiply this probability by the number of cups of the mix:

$=P(pretzel)\times (mix \ cups)\\\\=0.125\times 15\\\\=1.875 \ or \ 1\frac{7}{8}$

Hence, 1.875 or 1/7/8 cups of pretzel is needed.
