This graph relates the volumes of triangular pyramids with a base area of 12 square inches and their heights.

Nikolay [14]

Answer:

$V=40\ in^3$

Step-by-step explanation:

The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula

$V=\frac{1}{3}Bh$

where

B is the area of the triangular face

h is the height of the pyramid

we have

$B=12\ in^2\\h=10\ in$

substitute the given values

$V=\frac{1}{3}(12)(10)=40\ in^3$

Studentka2010 [4]

✡ Answer: x=6.72 ✡

- - Solve:

- - First step is to cross-multiply:
- $7.5*x=4.2*12$
- $7.5x=50.4$

- - The next step is to divide both sides by the number 7.5
- $\frac{7.5x}{7.5} = \frac{50.4}{7.5} 
$


- - x=6.72

Answer:

The length of side x is $x = \sqrt{6}$

Step-by-step explanation:

Pythagorean Theorem:

In a right triangle, with sides a and b, and hypothenuse h, we have that:

$a^2 + b^2 = h^2$

In this question:

The vertical line on the sides means that both are equal, that is, measuring x, so $a = b = x$ .

Hypothenuse is the square root of 12. So $h = \sqrt{12}$

$x^2 + x^2 = (\sqrt{12})^2$

$2x^2 = 12$

$x^2 = \frac{12}{2}$

$x^2 = 6$

$x = \sqrt{6}$

The length of side x is $x = \sqrt{6}$
