What is the volume of this triangular Pyramid photo attached
storchak [24]

To find the volume of a triangular pyramid, the formula is:

V=\frac{1}{3}(Area\text{ }of\text{ }thebase)(height)

So we start by finding the area of the base, which is in the shape of a right triangle in this case.

The area of a right triangle is equal to 1/2 x base x height.

\begin{gathered} A=\frac{1}{2}bh \\  \\ A=\frac{1}{2}(5)(6) \\  \\ A=15\text{ square feet} \end{gathered}

We use this area to find the volume.

\begin{gathered} V=\frac{1}{3}Ah \\  \\ V=\frac{1}{3}(15)(6) \\  \\ V=30\text{ cubic feet} \end{gathered}

The volume of the triangular pyramid is 30 cubic feet.

ZanzabumX [31]

The percent of time the photographer spent negotiating with the bison greater than the time he spent taking pictures is 500%

<h3>Percentage</h3>

  • Time spent taking pictures = 5 minutes
  • Time spent negotiating = 30 minutes

Percentage of time negotiating greater than taking pictures = (difference in time) / time to take pictures × 100

= (30 - 5) / 5 × 100

= 25/5 × 100

= 5 × 100

= 500%
