2. The volume of both of these trapezoidal prisms is 24 cubic units. Their

Valentin [98]

Answer:

area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively

Step-by-step explanation:

Let us first be aware of formula of volume for any regular geometrical figure.

Fundamental formula for volume for any regular geometrical figure is.

volume = area of cross section of object* height of object (A)

In the problem stated area of cross section of object will be area of a trapezoidal base.

Given in the question is

Volume of both the trapezoidal prisms = 24 cubic units

*************************************************************************************

For prism with height 6 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 6 * area of a trapezoidal base

=> area of a trapezoidal base = 24/6 = 4 square units

*************************************************************************************

For prism with height 8 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 8 * area of a trapezoidal base

=> area of a trapezoidal base = 24/8 = 3 square units

*************************************************************************************

Therefore area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively.

Explain weather or not the two triangles below could lie on the same line. Be sure to use the slope of each triangle in your jus

KonstantinChe [14]

Answer:

No, these triangles cannot lie on the same line.

Step-by-step explanation:

For two triangles to lie on the same line they must have the same slope.

The slope of the bigger triangle is

$m=\frac{rise}{run} =-\frac{18}{10} =-1.8$

and the slope of the smaller triangle is

$m=\frac{rise}{run} =-\frac{2}{3} =-0.67$

slopes are negative because the triangles are leaning to the left.

We see that the slopes of the two triangles are not the same; therefore, they cannot lie on the same line.
