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.

A brass ornament has a volume of 24cm^3.

dedylja [7]

For this case we have that by definition, the density is given by:

$d = \frac {M} {V}$

Where:

M: It is the mass

V: It is the volume

According to the data of the statement we have:

$V = 24 \ cm ^ 3\\d = 8.7 \frac {g} {cm ^ 3}$

So, the mass is given by:

$M = d * V\\M = 24 \ cm ^ 3 * 8.7 \frac {g} {cm ^ 3}\\M = 208.8 \ g$

Thus, the mass of the brass ornament is $208.8 \ g$

Answer:

$208.8 \ g$
