1. -10=xy+z, solve for x please? 2. h-4/j =k, solve for j please?​
ANEK [815]

Answer:

x=\frac{-10-z}{y}

Step-by-step explanation:

1 Subtract z from both sides.

-10-z=xy

2 Divide both sides by y

\frac{-10-z}{y} =x

3 Switch sides.

x=\frac{-10-z}{y}

2nd question

Answer: j=-\frac{4}{k-h}

Step-by-step explanation:

1 Subtract h from both sides

-\frac{4}{j} =k-h

2 Multiply both sides by j.

-4=(k-h)j

3 Divide both sides by k−h.

-\frac{4}{k-h}=j

4 Switch sides.

j=-\frac{4}{k-h}

A pile of sand in the shape of a cone has a diameter of 8 in. and a height of 5 in.
max2010maxim [7]

if it has a diameter of 8, that means its radius is half that, or 4.


\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}~~
\begin{cases}
r=radius\\
h=height\\[-0.5em]
\hrulefill\\
r=4\\
h=5
\end{cases}\implies V=\cfrac{\pi (4)^2(5)}{3}\implies V=\cfrac{80\pi }{3}

\rule{34em}{0.25pt}\\\\
~\hfill \stackrel{using~\pi =3.14}{V= 83.7\overline{3}}~\hfill
