What is the length of the diagonal, d, of the rectangular prism shown below?
vodomira [7]

Answer:

<h2>The diagonal of the volumetric figure is 7 units long.</h2>

Step-by-step explanation:

The figure is attached.

Notice that the dimensions of the prism are

w=2\\l=3\\h=6

First, we need to find the diagonal of the rectangular face on the base, this diagonal of the base is part of the right triangle formed by the diagonal of the volume, that's why we need it.

Let's use the Pythagorean's Theorem

d_{base}=\sqrt{2^{2} +3^{2} }=\sqrt{4+9}=\sqrt{13}

This diagonal of the base is a leg in the right triangle formed by the diagonal of the volume.

Let's use again Pythagorean's Theorem

d_{volume}=\sqrt{(\sqrt{13} )^{2}  +(6)^{2} }  =\sqrt{13+36}=\sqrt{49}\\ d_{volume}=7 \ units

Therefore, the diagonal of the volumetric figure is 7 units long.

Sonia has completed 14 levels of a video game and has 9 points so far in her current level. If Sonia has a total of 331 points,
Valentin [98]

The equation that can be used to find the number of points is 9 + (14 × x) = 331 and the value is 23.

<h3>How to illustrate the information?</h3>

From the information, Sonia has completed 14 levels of a video game and has 9 points so far in her current level and she has a total of 331 points.

Let the number of points earned be illustrated as x.

The equation that can be used to find the number of points she earned for completing each level will be:

9 + (14 × x) = 331

9 + 14x = 331

14x = 331 - 9

14x = 322

Divide

x = 322 / 14

x = 23

The number of points is 23.
