Answer:

650 kg/m³

Step-by-step explanation:

The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.

density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³

= 650 kg/m³

Hope this answer helps you :)

(1,-7) with a slope of -5 as an equation

Butoxors [25]

I'm assuming you want an equation with a slope of -5 that also passes through the point (1, -7).

An equation that fits this is

$y = - 5x - 2$

Hope this helps!

line k has a slope of -5. line j is perpendicular to line k and passes though the point (5,9) create the equation for line j

Anna71 [15]

Answer:

y = 1/5x + 8

Step-by-step explanation:

The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, the slope of line j is 1/5. This is your current equation: y=1/5x + b. Plug in your coordinate to the equation, it should look like this: 9=1/5(5)+ b. 1/5 times 5 equals 1, so this is what it should look like: 9=1 + b. Subtract 1 from both sides to get 8 = b. Go back to your original equation and plug in 8 to b. This is your final equation: y = 1/5x + 8. Hope this helped!

How do you find the surface area of a octahedron

Alenkasestr [34]

If it's a regular octahedron, then you can calculate it using the formula $2\sqrt3a^2$ where $a$ is the length of the edge.
If it's not regular, you have to calculate the area of each side individually.
