A boiler room has the shape of a rectangular prism. The area of the floor of the room is 112 square feet. The length of the room

is 2 feet more than twice the width. The height is 1 foot greater than the width. What is the volume of the room in cubic feet? Do not include units in your answer.

Answer:

The volume of the room is 42336.

Step-by-step explanation:

Given,

Area of the floor = 112\ ft^2

Let the width of the room be x.

Since the length of the room is 2 feet more than twice the width.

\therefore\ length=2x+2

Since the room is rectangular, so we use the formula of area of rectangle.

Area = length\times width

On substituting the values, we get;

(2x+2)\times2=112\\\\4x+4=112\\\\4x=112-4\\\\4x=108\\\\x=\frac{108}{4}=27

Width = 27

Length = 2x+2=2\times27+2=54+2=56

The height is 1 foot greater than the width.

\therefore Heigth=27+1=28

Now,

Length = 56    Width = 27     Heigth = 28

And we know volume of a rectangular prism is length times width times height.

Volume =length\times width\times\ height.

Volume = 56\times27\times28= 42336\ ft^3

Thus the volume of the room is 42336.

Answer:

896

Step-by-step explanation:

112=(2w+2)W

W=7,-8 cant be negitive so 7

L=(7)2+(7)=16

H=7+1=8

V=7*16*8

V=896

Drag each tile to the correct box. Vector t, with a magnitude of 4 meters/second and a direction angle of 60°, represents a swim
astraxan [27]

Answer:

From top to bottom, the boxes shown are number 3, 5, 6, 2, 4, 1 when put in ascending order.

Step-by-step explanation:

It is convenient to let a calculator or spreadsheet tell you the magnitude of the sum. For a problem such as this, it is even more convenient to let the calculator give you all the answers at once.

The TI-84 image shows the calculation for a list of vectors being added to 4∠60°. The magnitudes of the sums (rounded to 2 decimal places—enough accuracy to put them in order) are ...

... ║4∠60° + 3∠120°║≈6.08

... ║4∠60° + 4.5∠135°║≈6.75

... ║4∠60° + 4∠45°║≈7.93

... ║4∠60° + 6∠210°║≈3.23

... ║4∠60° + 5∠330°║≈6.40

... ║4∠60° + 7∠240°║≈ 3

_____

In the calculator working, the variable D has the value π/180. It converts degrees to radians so the calculation will work properly. The abs( ) function gives the magnitude of a complex number.

On this calculator, it is convenient to treat vectors as complex numbers. Other calculators can deal with vectors directly

_____

<em>Doing it by hand</em>

Perhaps the most straigtforward way to add vectors is to convert them to a representation in rectangular coordinates. For some magnitude M and angle A, the rectangular coordinates are (M·cos(A), M·sin(A)). For this problem, you would convert each of the vectors in the boxes to rectangular coordinates, and add the rectangular coordinates of vector t.

For example, the first vector would be ...

3∠120° ⇒(3·cos(120°), 3·sin(120°)) ≈ (-1.500, 2.598)

Adding this to 4∠60° ⇒ (4·cos(60°), 4°sin(60°)) ≈ (2.000, 3.464) gives

... 3∠120° + 4∠60° ≈ (0.5, 6.062)

The magnitude of this is given by the Pythagorean theorem:

... M = √(0.5² +6.062²) ≈ 6.08

___

<em>Using the law of cosines</em>

The law of cosines can also be used to find the magnitude of the sum. When using this method, it is often helpful to draw a diagram to help you find the angle between the vectors.

When 3∠120° is added to the end of 4∠60°, the angle between them is 120°. Then the law of cosines tells you the magnitude of the sum is ...

... M² = 4² + 3² -2·4·3·cos(120°) = 25-24·cos(120°) = 37

... M = √37 ≈ 6.08 . . . . as in the other calculations.
