The values of the integers lie between 29 and 39 and is 30,31,32,33,34,35,36,37,38.

A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.

A zero, a positive natural number, or a negative integer with a minus sign is an integer. The negative numbers are the additive inverses of their positive counterparts.

Given that the integers lie between the numbers 29 and 39. The numbers will be,

29, { 30,31,32,33,34,35,36,37,38 }, 39

Therefore, the values of the integers lie between 29 and 39 and are 30,31,32,33,34,35,36,37,38.

To find the median of a set of numbers, you need to arrange the numbers in order from smallest to largest, and then find the middle number. In this case, the numbers are already in order: 2, 3, 4, 4, 6, 9.

There are 6 numbers in the set, so the median is the middle number, which is 4.

the median value, which is arrived at by sorting all the data points and selecting the central one (or if there are two middle numbers, taking the mean of those two numbers). Example: When the numbers are sorted, the number 4 is in the middle (1, 4, 7), making it the median of the numbers 4, 1 and 7.

The relation between area, height and volume is: volume = area * height

In this question we need to find the relation between area height and volume.

the formula for area and volume are based on height:

volume = base area * height

Let v represents the volume, A represents area and h represents the height.

V = A * h

As we know the volume of rectangular prism is:

volume = length * width * height

i.e., V = l * w * h

and the base area is:

area = length * width

i.e., A = l * w

Substitute A =  l * w in V = l * w * h

Then we get, V = A * h

Therefore, the relation between area, height and volume is: V = A * h i.e., volume = area * height

Solving for two variables (normally denoted as "x" and "y") requires two sets of equations.

Assuming you have two equations, the best way for solving for both variables is to use the substitution method, which involves solving for one variable as far as possible, then plugging it back in to the other equation. Knowing how to solve a system of equations with two variables is important for several areas, including trying to find the coordinate for points on a graph.

Write out the two equations that have the two variables you want to solve. For this example, we will find the value for "x" and "y" in the two equations "3x + y = 2" and "x + 5y = 20"

Solve for one of the variables in on one of the equations. For this example, let's solve for "y" in the first equation. Subtract 3x from each side to get "y = 2 - 3x"

Plug in the y value found from the first equation in to the second equation in order to find the x value. In the previous example, this means the second equation becomes "x + 5(2- 3x) = 20"

Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7.

Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

Check your work by plugging in the x and y values in to both of the equations.

In the equation c(n) = 50+4n, the value of c(7) is equal to 78.

Absolutely one element of Y is assigned to every element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and codomain, respectively.

Al-Biruni and Sharaf al-Din al-Tusi were two Persian mathematicians who developed the earliest known approach to function and its concept. The basic conception of functions was the relationship between fluctuating quantities and other variables. An illustration of this is how time affects a planet's position. In the past, the idea was developed with the infinitesimal calculus around the end of the 17th century, and, until the 19th century, the functions that were considered were differentiable.

This is how the function is defined:

The equation c(n) = 50+4n defines function c, and n is the number of visits.

The function displays the cost in USD per month.

Thus, the following formula can be used to get the value of c(7):

c(7) = 50+4n

c(7) = 50+4(7)

= 50+28

=78

Therefore, c(7)=78

Answer: 17 gallons of gas to travel 748 miles

Step-by-step explanation:

First, we have to find how many miles he can travel with 1 gallon of gas

Take 308 divided by 7 = 44 miles of travel per gallon of gas

Then take 748 divided by 44 = 17 gallons

So, it takes 17 gallons of gas to travel 748 miles

Answer:

Isaac needs 17 gallons of gas to travel 748 miles.

Step-by-step explanation:

This problem is giving you the ratio of gallons to miles.

⭐A ratio is a fraction that compares two different units

⭐ In this problem, the units are gallons and miles

In order to find how many gallons Isaac needs to travel 748 miles, we need to create a proportion.

⭐ A proportion is when you make two ratios equal to each other to solve for one unit

First, let's identify the ratios in this situation. Let x = the number of gallons needed to travel 748 miles.

Ratio 1: 7 gallons/ 308 miles

Ratio 2: x gallons/748 miles

Now, set these two ratios equal to each other. Remember to keep the same units as either the numerator or denominator.

[tex]\frac{7}{308} = \frac{x}{748}[/tex]

Next, cross multiply to solve for x.

[tex]7(748) = 308x\\5,236 = 308x\\x = 17[/tex]

∴ Isaac needs 17 gallons of gas to travel 748 miles!

To find the total balance in an account that earns a simple interest rate of 8% per year, we can use the formula A = P(1 + rt), where A is the total balance, P is the initial principal (or amount invested), r is the annual interest rate, and t is the number of years. In this case, the annual interest rate is 8%, so we can substitute 0.08 for r in the formula. Since Kadeem wants to find his total balance in one step, we can set t equal to 1 year. So, to find Kadeem's total balance in one year in one step, he needs to multiply his current balance by 1 + 0.08 = 1.08. Therefore, Kadeem should multiply his current balance by 1.08 to find his total balance in a year in one step.

Harry's soccer team needs 168 people to attend their pancake breakfast in order to raise $2,520.

To find the number of people that need to attend the pancake breakfast, we can set up the following equation:

Number of People x Cost per Person = Total Cost

We know that the total cost is $2,520 and the cost per person is $15, so we can substitute those values into the equation:

Number of People x $15 = $2,520

We can solve for the number of people by dividing both sides of the equation by $15:

Number of People = $2,520 / $15

This gives us the number of people that need to attend the pancake breakfast in order to raise the desired amount of money. In this case, the number of people is 168.

Therefore, Harry's soccer team needs 168 people to attend their pancake breakfast in order to raise $2,520.

The function of the graph which is not connected with each other is known as a discontinuous function. A function f(x) is said to have a discontinuity of the first kind at x = a, if the left-hand limit of f(x) and right-hand limit of f(x) both exist but are not equal.

The function is an expression or law that defines a relationship between one variable and the independent variable and another variable the dependent variable

The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes because of this control

Some examples of a discontinuous function

f(x) = 1 / (x - 2)

The relationship between the volume of a sphere and the volume of a cylinder is: the volume of a sphere is 2/3 of the volume of a cylinder with same radius, and height equal to the diameter.

In this question we need to describe the relationship of the volume between the volume of a sphere and the volume of a cylinder.

Consider  a cylinder with radius r and height h.

we know that the formula for the volume of cylinder is,

V1 = π * r² * h

Consider a sphere with radius r1.

We know that the formula for the volume of sphere is,

V2 = 4/3 * π * r1³

If the sphere and a cylinder have same radii and height of cylinder equal to the diameter then, r1 = r and h = 2r

V2 = 4/3 * π * r³

And V1 = π * r² * (2r)

V1 = 2 * π * r³

V1 = 2 * 3/4 * V2

V1 = 3/2 * V2
