GREYUIT [131]

Answer:

<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>

Step-by-step explanation:

To find the mass in kg we must first convert the density from g/cm³ to kg/m³

That's 7.5 g/cm³ = 7500kg/m³

Density = mass / volume

Volume of block = 1.5 × 0.4 × 0.25

= 0.15m³

mass = Density × volume

= 7500 × 0.15

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.
