What is the volume?A right circular cone is a three dimensional object has a flat circular base that tapers to a vertex. The volume of a right circular cone is the amount of space in the right circular cone.
Volume of a cone = 1/3(πr²h)
Where:
π = pi = 3.14r = radius h = heightVolume of the right circular cone when its filled to a height of 3.70 = 1/3 x 3.14 x 3.70 x 1.20² = 5.58 m³
5.58 x 1000 = 5,580 liters
Volume of the right circular cone when it is full = 1/3 x 3.14 x 4 x 1.20² = 6.03 m³
6.03 x 1000 = 6030 liters
Liters that needs to be added to 100% capacity = 6030 liters - 5,580 liters = 480 liters

Solve. 2x – 5=-3x + 15
Answers
Explanation:
First we have to add 3x on both sides of the equation:
[tex]\begin{gathered} 2x-5+3x=-3x+3x+15 \\ 5x-5=15 \end{gathered}[/tex]Now add 5 on both sides:
[tex]\begin{gathered} 5x-5+5=15+5 \\ 5x=20 \end{gathered}[/tex]And finally divide both sides by 5:
[tex]\begin{gathered} \frac{5x}{5}=\frac{20}{5} \\ x=4 \end{gathered}[/tex]Answer:
x = 5
Answer:
[tex] \sf \: x = 4[/tex]
Step-by-step explanation:
Given equation,
→ 2x - 5 = -3x + 15
Now the value of x will be,
→ 2x - 5 = -3x + 15
→ 2x + 3x = 15 + 5
→ 5x = 20
→ x = 20 ÷ 5
→ [ x = 4 ]
Hence, the value of x is 4.

the sum of the reciprocal of two consecutive positive integers is 17/72. Write an equation that can be used to find the two integers. What are the integers?
Answers
Answer:
[tex]\frac{1}{x}+\frac{1}{x+1}=\frac{17}{72}[/tex]The two consecutive positive integers are 8 and 9.
Explanation:
Let the 1st positive integer be x and the 2nd be x + 1, so their reciprocal will be 1/x and 1/x+1.
The equation can then be written as;
[tex]\frac{1}{x}+\frac{1}{x+1}=\frac{17}{72}[/tex]To solve for x, the 1st step is to find the LCM of the left-hand side of the equation;

the length of a rectangle is two more than the width. if the perimeter is 28, find the length and the width of the rectangle, let w represent the width and l represent the length.
Answers
You have that the perimeter of a rectangle is 28. In order to find the values of length and width of the rectangle, you take into account the following formula for the perimeter of a rectangle:
[tex]P=2w+2l[/tex]where w is the width and l is the length. You have that the length l is twice the width w of the rectangle, that is l=2w. By replacing this expression for l into theformula for the calculation of the perimeter you obtain:
[tex]P=2w+2(2w)=2w+4w=6w[/tex]Thus, you have that P = 6w. You solve this equation for w, and also replace the value of P, just as follow:
[tex]\begin{gathered} P=6w \\ w=\frac{P}{6}=\frac{28}{6}=\frac{14}{3}=4.66 \end{gathered}[/tex]Then, the width is 4.66. The length is:
[tex]l=2w=2(4.66)=9.33[/tex]length = 9.33

complete the square to writey= x2 + 4x +9 in graphing form.
Answers
In order to express y = x² + 4x +9 in graphing form and graphing it we can follow these steps:
1. complete squares to express the equation in the form y = (x - p)² + q
We have to add and subtract (b/2)² on the right, where b is the coefficient of the second term of the equation
y = x² + 4x +9 + (4/2)² - (4/2)²
y = x² + 4x +9 + (2)² - (2)²
We can gorup and factor some terms of the equation by applying the following formula:
(x + a)² = x² + 2ax + a²
then by writing 4x as 2×2x we get:
y = x² + 2×2x + (2)² - (2)² +9
y = (x + 2)² - (2)² + 9
y = (x + 2)² - 4 + 9
y = (x + 2)² + 5
For an equation of the form y = (x - p)² + q, the vertex is (q, p), then, the vertex of the parabola is (-2, 5)
2. Determine the x-intercepts by replacing 0 for y and solving for x, like this:
0 = (x + 2)² + 5
0 - 5 = (x + 2)² + 5 - 5
-5 = (x + 2)²
±√-5 = √(x + 2)²
±√-5 = x + 2
x = -2 ± √-5
As you can see, on the right side the argument of the square root is a negative number, which makes the solution of this equation a complex number, then which means that the parabola won't intercept the x-axis.
3. Find the y-intercept by replacing 0 for x:
y = (0 + 2)² + 5
y = (2)² + 5
y = 4 + 5
y = 9
Then, the y-intercept of this parabola is (0, 9)
By graphing the vertex (-2, 5) and the y-intercept (0, 9) and joining them with the parabola we get the following graph:

It purchases these hats for $42 each.
It can provide a custom service to print the new owner’s name on the hatband.
The printing machine costs $243 per month to rent. If Old-Tyme sells the hats at a price of $69 each, how many does it need to sell to break even=?
The cost function to make n hats is:
C(n) = 42*n + 243 dollars.
The revenue function is
R(n) = 69*n dollars.
The break event equation/inequality is
R(n) ≥ C(n), or
69*n ≥ 243 + 42*n.

n ≥ 243/27 = 9.
