The bells are adding a new room to their house. The room will be a cube with volume 8,000 ft^3. They are going to put in hardwoo

Mandarinka [93]

Answer:

$4000

Step-by-step explanation:

Given that :

Volume of cube = 8000 ft³

Charge per ft² = $10

Recall, volume of a cube = a³

Where a = edge

Hence,

a³ = 8000

Take the cube root of both sides

a = 20

Hence,

Volume = 20 * 20 * 20

The Area of the floor will be :

20 * 20 = 400 ft²

If charge per ft² = $10

400 ft² = ($10 * 400) = $4000

$\text{Hello there!}\\\\\text{We're trying to find the area of the shape}\\\text{We can do this by finding the area for the different shapes, then adding}\\\text{them together}\\\\\text{We can find the area of the rectangle,} \,\,84\cdot66=5,544\\\\\text{To find the area of the half circle, we would use the equation:}\,\,A=\frac{3.14r^2}{2}\\\\\text{The radius is half of the diameter, therefore it is 33.

$A=\frac{3.14(1089)}{2}\\\\A=\frac{3419.46}{2}\\\\\text{Divide by 2}\\\\A=1709.73\\\\\text{Since there's two half circles, we would add 1709.73 twice}\\\\\text{Add all the areas together}\\\\1709.73+1709.73+5,544=8963.46\\\\\large\boxed{\text{Area:}\,\,8963.46\,\,\text{m}^2}}$

Identifying the Graph of a System of Two-Variable Linear

vekshin1

The graph of the given system of inequalities can be seen at the end of the answer.

<h3 /><h3>How to get the graph of the system of inequalities?</h3>

Here we have the system of inequalities:

x + 3y > -3

y < 2x + 1

first, we can write both of these in the form of a line equation in the slope-intercept form.

y > (-3 - x)/3 = -1 - (1/3)*x

y < 2x + 1.

To graph this, we first need to draw the two lines as dashed lines (because the points on the lines are not solutions).

Then for the line:

y = -(1/3)*x - 1 we need to shade the region above the line (because the symbol > is used).

For the line:

y = 2x + 1

We need to shade the region below the line, because the symbol used is <.

Then the graph of the system of inequalities is the one you can see below. The solutions of the system are the ones where the two shaded regions intercept.
