\boxed{-2\left(z+5\right)+20>6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:z

<em><u>Solution:</u></em>

<em><u>Given inequality is:</u></em>

-2(z+5)+20>6

We have to solve the given inequality

-2\left(z+5\right)+20>6\\\\\mathrm{Subtract\:}20\mathrm{\:from\:both\:sides}\\\\-2\left(z+5\right)+20-20>6-20\\\\\mathrm{Simplify}\\\\-2\left(z+5\right)>-14

Multiply\ both\ sides\ by\ -1\ \left(reverse\:the\:inequality\right)

Whenever we multiply or divide an inequality by a negative number, we must flip the inequality sign

\left(-2\left(z+5\right)\right)\left(-1\right)

<em><u>Thus the solution to inequality is:</u></em>

-2\left(z+5\right)+20>6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:z

What is the volume of this pyramid?<br><br> • 7560 cm³<br> • 5040 cm³<br> • 2520 cm³<br> • 1728 cm³
gavmur [86]

Answer:

Volume = 2520 cm^3.

Step-by-step explanation:

The volume of a pyramid = 1/3 * area of the base * height.

The base of this pyramid is a triangle and its area

= 1/2 * 18 * 24 cm^2 so the volume of the pyramid is:

1/3 * 1/2 * 18 * 24 * 35

= 2520 cm^3.
