A storage tank for propane gas is to be constructed in the shape of a right circular cylinder of altitude 20 feet with a hemisphere attached to each end. determine the radius x so that the resulting volume is 216π ft3.
To determine the radius x of the storage tank, we need to break down the shape into smaller parts. We can set up a cubic equation to find the value of r, and then calculate the radius x.
To determine the radius x of the storage tank, we need to break down the shape into smaller parts. First, let's consider the cylinder. The volume of a cylinder is given by V = πr^2h, where r is the radius and h is the altitude. In this case, the altitude is 20 feet. So, the volume of the cylinder is Vcylinder = πr^2(20).
Next, let's consider the hemispheres attached to each end. The volume of a hemisphere is given by V = (2/3)πr^3. Since there are two hemispheres, the total volume of the hemispheres is Vhemispheres = (2/3)(2)(πr^3) = (4/3)πr^3.
Given that the resulting volume is 216π ft3, we can set up the equation:
216π = Vcylinder + Vhemispheres = πr^2(20) + (4/3)πr^3
Simplifying and rearranging the equation, we get:
3r^3 + 60r^2 - 216 = 0
By solving this cubic equation, we can find the value of r. Once we have the value of r, we can determine the radius x by subtracting the radius of the hemispheres (r) from the total radius of the tank (x+r).

When is the sum of two complex numbers a real number? When is the sum of two complex numbers an imaginary number?
The sum of two complex numbers resulting in a real or imaginary number depends on the cancellation of their real or imaginary components upon addition.
When the sum of two complex numbers is a real number: For the sum of two complex numbers to be a real number, their imaginary parts must cancel each other out. This happens when the imaginary parts have equal magnitude but opposite signs, resulting in the cancellation upon addition.
When the sum of two complex numbers is an imaginary number: The sum of two complex numbers is an imaginary number when the real parts cancel each other out. This occurs when the real parts have equal magnitude but opposite signs, leading to the elimination of the real components.

The function BN equals 6n represents the number of light bulbs BN that are needed for n chandeliers how many light bulbs are needed for 15 chandeliers
BN =6n
n = chandeliers
you have 15 chandeliers so n = 15
so BN = 6(15)
BN = 90
you will need 90 light bulbs
A veterinary office takes out a loan to purchase a new set of digital animal scales that costs $12,250. The interest rate is 6.5%, and the total interest paid is $2,388.75. How many years is the loan for?
The loan is for approximately 3 years.
Explanation:To find the number of years for the loan, we can use the formula for simple interest:
Interest = Principal * Rate * Time
Given that the principal is $12,250, the rate is 6.5%, and the total interest paid is $2,388.75, we can rearrange the formula to solve for time:
Time = Interest / (Principal * Rate)
Plugging in the values, we get:
Time = 2,388.75 / (12,250 * 0.065)
Simplifying the expression, we have:
Time ≈ 3 years

Find the distance between the points (-2, 4) and (4, -6).
2√2
2√(10)
2√(34)
Answer: The correct option is (C) 2√34.
Step-by-step explanation: We are given to find the distance between the points (-2, 4) and (4, -6).
We have the distance formula as follows :
DISTANCE FORMULA :
The distance between the points (a, b) and (c, d) is given as
[tex]D=\sqrt{(c-a)^2+(d-b)^2}.[/tex]
Therefore, the distance between the points (-2, 4) and (4, -6) is given by
[tex]D\\\\=\sqrt{(4-(-2))^2+(-6-4)^2}\\\\=\sqrt{6^2+10^2}\\\\=\sqrt{36+100}\\\\=\sqrt{136}\\\\=\sqrt{4\times34}\\\\=2\sqrt{34}.[/tex]
Thus, the required distance between the given points is 2√34 units.
Option (C) is CORRECT.

One-eleventh of all sales at Joe's Diner are for cash. If cash sales for the week were $380, what were Joe's total sales?
To find Joe's total sales when one-eleventh are cash sales amounting to $380, multiply the cash sales by 11, which results in a total of $4180.
To find Joe's total sales, one would apply the concept of proportions in mathematics. Here is a step-by-step breakdown of the problem:
Identify the fraction of total sales that are cash, which is one-eleventh.
Understand that $380 equals this fraction of the total sales.
To find the total sales, divide the cash sales by the fraction that represents cash sales 1/11
Calculate the total sales by using the following equation: Total Sales = Cash Sales / (1/11) = $380 / (1/11).
Perform the division: Total Sales = $380 * 11 = $4180.
Hence, Joe's total sales for the week were $4180.

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Total present money initially = $1200
Deposits check = 387.89 + 437.12 + 250 = $1075.01
Total money after deposit = 1200 + 1075.01 = $2275.01
Money remains after withdrawals of $400
⇒ $2275.01 - $400 = $1875.01.
Hence "The total present money in his account after all the $400 withdrawals is $1875.01".
