D. 4√2

Step-by-step explanation:

A triangle with 45°, 45°, and 90° is a special right triangle.

hypotenuse = √2 · leg

1. Set up the equation

8 = √2 · x

2. Divide by √2 and solve

x = \frac{8}{\sqrt{2} } · \frac{\sqrt{2} }{\sqrt{2}} = \frac{8\sqrt{2} }{2} = 4√2

The volume of a cone is 3πx3 cubic units and its height is x units. Which expression represents the radius of the cone’s base, i
dalvyx [7]

Answer:

<em>r=3x</em>

Step-by-step explanation:

<u>The Volume of a Cone</u>

The volume of a cone of radius r and height h is:

\displaystyle V=\frac{1}{3}\pi hr^2

We are given the volume of a cone is

V=3\pi x^3

Equating:

\displaystyle \frac{1}{3}\pi hr^2=3\pi x^3

Multiplying by 3:

\pi hr^2=9\pi x^3

Simplifying by pi:

hr^2=9 x^3

Since h=x:

xr^2=9 x^3

Dividing by x:

r^2=9 x^2

Taking square roots:

r=\sqrt{9 x^2}=3x

Thus: r=3x

Why might a mattress store choose to advertise new mattresses, worth $1,000, as $50 per week for 22 weeks?
IgorLugansk [536]
By doing so, they provide the illusion that the payments are cheaper then 1000 dollars, because 50 looks very small, when in reality it's $100 more then what the mattress is actually worth.

Write an inequality that represents the following:
Scilla [17]

Answer:

The maximum number of hours can be spend on work is 4 hours

Step-by-step explanation:

Given as :

The fixed charge of an auto shop = $100

The labor charge of auto shop = $175 per hour

The maximum money to be spend = $800

Let The maximum number of hours can be spend on work = n hours

<u>According to question</u>

The maximum money to be spend = fixed charge of an auto shop + labor charge of auto shop per hour × maximum number of hours

Or, $800 = $100 + $175 × n

Or, $175 × n = $800 - $100

Or, $175 × n = $700

∴ n = \frac{700}{175}

i.e n = 4

So, The maximum number of hours can be spend on work = n = 4 hours

Hence, maximum number of hours can be spend on work is 4 hours Answer
