The equation represents the volume of the portable fuel tank in terms of width (w) is w³ + 34w² + 145w - 33488 = 0.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A portable fuel tank used to transport gasoline is in the shape of a rectangular prism.
The tank is 5 feet longer than it is wide and 29 feet deeper than it is wide.
The volume of the tank is 33,488 cubic feet.
Let the width of the rectangular prism be w. Then we have
length = w + 5
height = w + 29
Then the volume is given as
Volume = l × w × h
33488 = (w + 5) (w) (w + 29)
Then we have
[tex]\begin{aligned} \rm w^3 + 5w^2 + 29w^2 + 145w &=33488 \\\\\rm w^3 + 34w^2 + 145w - 33488 &= 0\\\\\rm (w - 23)(2w+57)(2w + 57) &= 0\\\\\rm w &= 23, -28.5, -28.5 \end{aligned}[/tex]

I solved this.
Answer:
[tex]-\frac{35}{18}[/tex]
Step-by-step explanation:
[tex]\frac{5}{3}[/tex] ÷ [tex]-\frac{6}{7}[/tex] is the same as [tex]\frac{5}{3}[/tex] × [tex]-\frac{7}{6}[/tex]
Multiply across:
5 x 7 = 35

Answer:
Option A
Step-by-step explanation:
Convert mixed fraction to improper fraction.
[tex]\sf w - 9\dfrac{1}{2}=15\\\\ w - \dfrac{19}{2}=15[/tex]
Now isolate 'w'
[tex]\sf w = 15 +\dfrac{19}{2}\\\\= \dfrac{15*2}{1*2}+\dfrac{19}{2}\\\\=\dfrac{30}{2}+\dfrac{19}{2}\\\\=\dfrac{30+19}{2}\\\\=\dfrac{49}{2}\\\\= 24\dfrac{1}{2}[/tex]
Answer:
[tex]\huge\boxed{\bf\:w = \frac{49}{2} = 24\frac{1}{2} = 24.5}[/tex]
Step-by-step explanation:
[tex]w - 9 \frac { 1 } { 2 } = 15[/tex]
Multiply both the sides of the equation by 2.
[tex]2w-\left(9\times 2+1\right)=30 \\2w-\left(18+1\right)=30 \\2w-19=30[/tex]
Bring [tex]19[/tex] to the left hand side of the equation.

If P and Q are points on a circle, then the center of the circle must be on the perpendicular bisector of chord P Q. Explain. Which point on the chord is closest to the center? Why?
The center of the circle must be on the perpendicular bisector of chord PQ since it passes through the center.
What is a perpendicular bisector?It should be noted that a perpendicular bisector simply means a line the intersect another line through the intersection point.
In this case, the center of the circle must be on the perpendicular bisector of chord PQ since it passes through the center. This bisects it at a right angle. The chord closer to the centimeter will be the one closer to the diameter.

Graph the line with slope 3/2 and y-intercept 3.
Answer:
The steepness of any incline can be measured as the ratio of the vertical change to the horizontal change. For example, a 5 % incline can be written as 5100 , which means that for every 100 feet forward, the height increases 5 feet.Figure 4.4.1 In mathematics incline of a line the slope and use the letter m to denote it. The vertical change is called the rise and the horizontal change is called the run.Slopem=vertical changehorizontal change=riserun(4.4.1)The rise and the run can be positive or negative. A positive rise corresponds to a vertical change up and a negative rise corresponds to a vertical change down. A positive run denotes a horizontal change to the right and a negative run corresponds to a horizontal change to the left. Given the graph, we can calculate the slope by determining the vertical and horizontal changes between any two points.Example 4.4.1 Figure 4.4.2 From the given points on the graph, count 3 units down and 4 units right.m=riserun=−3units4units=−34 the Answer is.m=−34 .

represents one foot, what is the area of Eunice's kite?
The area of Eunice's kite is [tex]2\sqrt{58}[/tex].
What is the kite?A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces.
Eunice is flying a kite with vertices at points A(0, 0), B(0, 4), C(7, 7), and D(4, 0).
If the diagonals in a quadrilateral are perpendicular to each other then the area is one-half of the product of the diagonals.
All Kites and rhombi fall in this category.
By the distance formula;
[tex]\rm AB =\sqrt{(0-0)^2+(4-0)^2} =\sqrt{0+16} =\sqrt{16} =4\\\\BC =\sqrt{(7-0)^2+(7-4)^2} =\sqrt{49+9} =\sqrt{58} \\\\CD =\sqrt{(4-7)^2+(0-7)^2} =\sqrt{49+9} =\sqrt{58}\\\\AD =\sqrt{(0-0)^2+(4-0)^2} =\sqrt{0+16} =\sqrt{16} =4\\[/tex]
The area of Eunice's kite is;
[tex]\rm Area = \dfrac{1}{2} \times AB \times BC\\\\Area =\dfrac{1}{2} \times 4 \times \sqrt{58} \\\\Area =2\sqrt{58}[/tex]

The volume of this CONE is 175π cubic units.
What is the volume of a CYLINDER with the same radius and the same height?
Answer:
1649.33 units³
Step-by-step explanation:
Let the height and the radius be known as "h" and "r" respectively.
Formulae(s):
Volume of cylinder: πr²hVolume of cone: πr²h/3Clearly, we can see that the volume of the cylinder is three times greater than the volume of the cone as,
⇒ πr²h = 3(πr²h/3)⇒ πr²h = πr²h (True)Determining the volume of the cylinder;
⇒ Volume of cylinder = Volume of cone × 3⇒ Volume of cylinder = 175π × 3⇒ Volume of cylinder = 525π⇒ Volume of cylinder = 1649.33 units³ (2 d.p)Therefore, the volume of the cylinder is 1649.33 units³.
PAOLA GAVE AWAY 42 OF HER BOOKS SHE NOW HAS 150 BOOKS CALCULATE THE PERCENT CHANGE
HINT: how many books did she HAVE
please help me
Answer:
21.875%
Step-by-step explanation:
We need an equation to represent this problem,
Let x be the number of books she had before giving away 42 of them,
x - 42 = 150
To find out how many books she had before turn the problem around and add 42 with 150,
150 + 42 = x
⇒ x = 192
Now that you know that divide 42 by 192,
Let n be the quotient of 42/192
42/192 = n
⇒ n = 0.21875
Now to turn that into a percent move the decimal 2 spaces to the left,
0.21875
⇒ 2.1875
⇒ 21.875%
Therefore there was a 21.875% change.

Answer:
1. $1,122
2. $485.25
3. $440
4. $2,047.25
Step-by-step explanation:
1. 22 feet * 17 feet = 374 square feet * $3 per square foot = $1,122
2. 17 feet * 10 feet * 4 walls = 680 square feet. 680 feet - (7ft*3ft for the door) - (2*2ft*3ft for the windows) = 647 square feet * $0.75 per square foot = $485.25
3. 374 square feet/ $88 per gallon = 4.25 gallons which rounds up to 5 gallons, and 5 gallons at a cost of $88 per gallon = $440
4. $1,122 + $485.25 + $440 = $2,047.25
