Samuel has 1 cup of rubbing alcohol and will use the entire amount. He plans to store the cleaning solution in containers that each hold a maximum of 6 cups. How many containers does he need.

Answer:

b = 11

Step-by-step explanation:

2(3b + 6) = 78 (divide both sides by 2 )

3b + 6 = 39 ( subtract 6 from both sides )

3b = 33 ( divide both sides by 3 )

b = 11

Answer:

2(3b+6) = 78

6b+ 12 = 78

Subtract 12 from both sides

6b+ 12 = 78

6b+12-12=78-12

6b = 66

b = 11

To write 21600000 in standard form, we need to move the decimal point to the left or right so that there is only one non-zero digit to the left of the decimal point.

21600000 in standard form would be written as 2.16 x 10^7. Standard form, also known as scientific notation, is a way of expressing a number in a compact and efficient manner. It is typically used for very large or very small numbers. To write a number in standard form, the decimal point is moved so that there is only one non-zero digit to the left of the decimal point.

The number of places the decimal point is moved is indicated by a power of 10. In the case of 21600000, the decimal point is moved 7 places to the left, giving us 2.16 x 10^7. This notation makes it easy to compare numbers of different magnitudes, and it simplifies calculations involving large or small numbers. It is commonly used in scientific, engineering and mathematical fields. A standard form is a useful tool for expressing numbers in a clear and concise way.

The equation (2/3)x = 9/8 represents the question "How many 2/3's are in 9/8?" because it shows that the unknown number of 2/3's (represented by x) multiplied by 2/3 equals 9/8.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

The following equation represents the question "How many 2/3's are in 9/8?" because it shows that the unknown number of 2/3's (represented by x) multiplied by 2/3 equals 9/8.

(2/3)x = 9/8

To find out how many 2/3's are in 9/8, you would need to solve for x by dividing both sides of the equation by 2/3.

⇒ x = (9/8)/(2/3)

⇒ x = (9/8) × (3/2)

⇒ x = 27/16

10) Using the equation 98.4 = (12.3)8, it costs $12.30 (cost per unit) per uniform.

11) Using the equation 26.70 = k6, the cost of one bag of apples (unit rate) is $4.45.

The unit rate is the quotient of the total cost divided by the number of items contained.

The unit rate is the same as the average or mean of a data set.

We describe the unit rate as the slope of a linear equation.

The unit rate shows the constant rate of change in an equation.

The total cost of 8 uniforms = 98.4 = (12.3)8

The cost per uniform = 12.30 (98.4/8)

The total cost of 6 bags of apples = 26.70

The cost per unit = 4.45 (26.70/6)

The end behavior for f(x)=x^5 is asymptotic growth to positive infinity as x approaches positive infinity and asymptotic growth to negative infinity as x approaches negative infinity.

Asymptotic growth is a term used to describe the behavior of a function as it approaches a certain value, usually infinity. In mathematics, an asymptotic function is one that grows or shrinks towards a certain point without ever actually reaching it. In other words, it approaches a limit without bound. Asymptotic growth is often used to describe the rate of growth of a function as its input values approach infinity. It is also used to describe the rate at which a function expands or contracts as its argument approaches a certain point. Asymptotic growth is a useful concept in many areas of mathematics, from calculus to number theory.

This is because x^5 becomes increasingly larger as the absolute value of x increases, resulting in an ever-growing value of f(x).

There are mainly two types of logarithmic functions - common logarithm and natural logarithm.

Common logarithm (log): The logarithm function with base 10, it is represented as log10(x) or simply log(x) if the base is not specified.

Natural logarithm (ln): The logarithm function with base e (approx 2.718), it is represented as ln(x)

These two logarithmic functions are the most commonly used and have many applications in mathematics, physics, engineering, and other sciences. They are inverse functions of the exponential functions (10^x and e^x) respectively.

Additionally, there are other types of logarithms, such as logarithms with bases other than 10 or e, for example log2(x) which is logarithm with base 2, it is used in information theory and computer science.

The Arc AB = (π * r * 38) / 180.

What is central angle?

A central angle is the angle formed when two radii intersect at the center of a circle.

Since chord CB is a diameter of the circle, angle B is a right angle and measures 90 degrees. Arc AB is half the circumference of the circle, so its measure is equal to half the circumference times the ratio of the central angle to the total central angle (360 degrees) of the circle.

Let r be the radius of the circle. Then the circumference is 2 * π * r and the measure of arc AB is:

Arc AB = (1/2) * 2 * π * r * (angle B / 360)

Arc AB = (π * r * angle B) / 180

Arc AB = (π * r * 38) / 180

Therefore, Arc AB would be (π * r * 38) / 180.

[tex]x^{2} +3x+2 = 0[/tex]

Where,

a = 1

We will solve this problem with the help of a Binomial equation.

Let the number of adults is X and the number of children is Y.

Our first equation will be =

X + Y = 92

The total cost for adults is $3 and for Children is $2.25.

The total receipt for the concert is $246.75.

Our second equation will be =

3X + 2.25Y = 246.75

From equation 1, we get

X + Y = 92

X = 92-Y

Substitute this in equation second equation, and we get

3(92-Y) + 2.25Y = 246.75

276 - 3Y + 2.25Y = 246.75

-0.75Y = 246.75 - 276
