What is equation?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.
x= total minutes -4 the 1st 4 minutes are included in the .30
total cost = .3 + .18 x

Tickets for a celebrity golf tournament were sold before the tournament and on the day of the tournament. After reviewing ticket sales, the tournament director found that 150 fewer tickets were purchased on the day of the tournament than before the tournament. A total of 898 tickets were sold. How many tickets were sold on the day of the tournament?
524 tickets
748 tickets
314 tickets
374 tickets
Answer:
Step-by-step explanation:
Let x be the number of tickets sold before the tournament.
The number of tickets sold on the day of the tournament is x - 150 (since 150 fewer tickets were purchased on the day of the tournament than before the tournament)
The total number of tickets sold is the sum of the number sold before the tournament and on the day of the tournament.
x + (x - 150) = 898
Combining like terms:
2x = 1048
To find the number of tickets sold on the day of the tournament, we need to divide by 2:
x = 1048/2
x = 524
Therefore, 524 tickets were sold before the tournament and x - 150 = 524 - 150 = 374 tickets were sold on the day of the tournament.

6 ft tall man walks at the rate of 5 ft/sec toward a street light that is 16 ft above the ground. a. at what rate is the length of his shadow changing when he is 10 ft from the base of the light?
According to the concept of differentiation the length of his shadow changing when he is 10 feet from the base of the light is 10 feet.
Here we have given that the height of man = 6 feet
And the Height of light is 15 feet
Then the Rate of walk by man is written as
=>dx/dt = 5 feet per second.
Here we have to find the rate at which the tip of his shadow is moving when he is 10 feet from the base of the light.
Here by using ratio of similar triangles we have write it as,
=> 15/y = 6/(y - x)
When we do the cross multiplication on it, then we get
=> 15(y - x) = 6y
=> 15y - 6y = 15x
=> 9y = 15x
When we dividing by 3 on both sides then we get
=> 3y = 5x
While we differentiating both sides with respect to t then we get
=> 3(dy/dt) = 5(dx/dt)
=> dy/dt = (5/3)(6)
When we simplify this one, then we get
=> dy/dt = 10 ft/s
Hence the rate at which the tip of his shadow is changing is 10 ft/s.

what are expressions?
Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
Now,

In this problem we present another way of discovering the second linearly independent solution of (1) when the roots of the auxiliary equation are real an equal. (a) If m_1 notequalto m_2, verify that the differential equation y" - (m_1 + m_2)y' + m_1 m_2y = 0 hasy = e^m_1x - e^m_2 x/m_1 - m_2 as a solution. (b) Think of m_2 as fixed and use I'Hospital's rule to find the limit of the solution in part (a) as m_1 rightarrow m_2. (c) Verify that the limit in part (b) satisfies the differential equation obtained from the equation in part (a) by replacing mi by m_2.
All the Individuals solutions are solved below:
a) To verify that y = e^m_1x - e^m_2 x/m_1 - m_2 is a solution of the differential equation y" - (m_1 + m_2)y' + m_1 m_2y = 0, we can substitute y into the equation and simplify:
y" = m_1^2e^m_1x - m_2^2e^m_2x
y' = m_1e^m_1x - m_2e^m_2x
so:
y" - (m_1 + m_2)y' + m_1 m_2y = m_1^2e^m_1x - m_2^2e^m_2x - (m_1 + m_2)(m_1e^m_1x - m_2e^m_2x) + m_1 m_2(e^m_1x - e^m_2x/m_1 - m_2) = 0
b) To find the limit of the solution in part (a) as m_1 right arrow m_2, we can use I'Hospital's rule. The limit is:
lim (m_1 -> m_2) e^m_1x - e^m_2 x/m_1 - m_2 = e^m_2x - e^m_2 x/m_2 - m_2 = e^m_2x - e^m_2x - m_2 = -m_2
c) To verify that the limit in part (b) satisfies the differential equation obtained from the equation in part (a) by replacing mi by m_2, we can substitute -m_2 into the equation:
y" - (m_2 + m_2)y' + m_2 m_2y = 0
y" - 2m_2y' + m_2^2y = 0
which is the differential equation of a constant function, and -m_2 is a constant function. Therefore, the limit in part (b) satisfies the differential equation.
It should be noted that the solution y = e^m_1x - e^m_2 x/m_1 - m_2 is a linearly independent solution of the differential equation y" - (m_1 + m_2)y' + m_1 m_2y = 0, and it can be used in combination with the general solution y = c_1e^m_1x + c_2e^m_2x to find the general solution of the differential equation.

ten students wrote a test, and the distribution of scores is shown on the frequency table. if the average (arithmetic mean) score is 62, what is the value of x ?
From the given information, the value of x in the given table is 42.5.
To find the value of x, we can use the formula for the arithmetic mean (average) of a set of numbers:
Arithmetic mean = (sum of all numbers) / (number of numbers)
Given that the average score on the test is 62, we can use this information to find the sum of all the scores.
Given that number of students is 1,2,3 and 4 with scores of 40,55,70 respectively, we can use this information to find the sum of all the scores.
Sum of all scores = (1 * 40) + (2 * 55) + (3 * 70) + (4 * x)
Now we can substitute the given average score and the number of students into the equation and solve for x.
62 = (1 * 40) + (2 * 55) + (3 * 70) + (4 * x) / 10
620 = 40 + 110 + 210 + 4x
4x = 170

Why is 1 called a universal factor?
1 is a universal factor. It is a factor of all numbers. The number itself is a factor of the number as it divides itself entirely.
A factor is a number that divides another number and leaves no remainder. In other words, if multiplying two whole numbers gives us a product, the numbers we are multiplying are factors of the product because they are divisible by the product. There are two processes for finding factors: multiplication and division.
For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 absolutely and 12 ÷ 6 = 2 absolutely. The other factors of 12 are - 1, 2, 4, and 12.

When the volume of this sphere is [tex]$\frac{K \sqrt{6}}{\sqrt{\pi}}$[/tex], then the value of K is 8
As per the data given:
The length of the cube is 2 units.
First, we have to determine the surface area of the cube.
The formula for the surface area of the cube:
A = 6 (side × side)
A = 6 (2 × 2)
A = 6 (4)
A = 24 square units
The surface area of a cube is 24 square units.
Also given that the surface area of a cube and the surface area of a sphere is equal.
The formula for the surface area of the sphere.
A = 4π [tex]r^{2}[/tex]
Where r is the radius of the sphere.
4π [tex]r^{2}[/tex] = 24
π [tex]r^{2}[/tex] = 6
[tex]r^{2}[/tex] = [tex]\frac{6}{\pi }[/tex]
r = [tex]\sqrt{\frac{6}{\pi } }[/tex]
The radius of the sphere is [tex]\sqrt{\frac{6}{\pi } }[/tex]
Also given the volume of the sphere as [tex]$\frac{K \sqrt{6}}{\sqrt{\pi}}$[/tex]
Here we have to determine the value of K.
The volume of sphere = [tex]\frac{4}{3} \pi r^{3}[/tex]
Where r is the radius of the sphere.
[tex]\frac{4}{3} \pi r^{3}[/tex] = [tex]$\frac{K \sqrt{6}}{\sqrt{\pi}}$[/tex]
[tex]\frac{4}{3} \pi (\sqrt{\frac{6}{\pi } }) ^{3} = \frac{K \sqrt{6} }{\sqrt{\pi } }[/tex]

u3 = 6² + 5 = 36 + 5 = 41
c) To find un, we can use the term-to-term rule and substitute the value of un-1 into the equation.
un = un-1² + 5
It's important to note that the value of n is not given so we can't calculate the value of un.
Therefore, u1 = 6, u2 = 41, and we can't calculate un without knowing the value of n.
A tank hold 49 literof oil. If 7 liter leak what the percentage of oil ha leaed?
The percentage of oil that has leaked from the tank is 14.29%.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100.
Given that,
The capacity of the tank = 49 litres.
Total litres of oil leaked = 7 litres.
Mathematically, the percentage for the amount of oil leakage in this tank is given by this formula:
Percentage = oil leakage/tank capacity *100
Substituting the given parameters into the formula, we have:
Percentage = 7/49 *100 = 14.29%
Thus, The percentage of oil that has leaked from the tank is 14.29%.

Shaded picture where tree can be planted is attached below as per the scaling given.
What is Scale?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult. This change makes the idea of size significant in two different ways.
Given, Here is a scale drawing of a garden. The scale is 1 cm to 2m
A tree is going to be planted. The tree must be more than 4 m from the patio. The tree must be more than 6m from the pond.
Since Scale is 1: 200
Planted tree distance from Patio = 4 m = 400 cm
in picture = 400 * 1: 200
in picture, Planted tree distance from Patio= 2 cm
Planted tree distance from Ppnd = 6 m = 600 cm
in picture = 600 * 1: 200
in picture, Planted tree distance from Patio= 3 cm
Therefore, Shaded picture where tree can be planted is attached below as per the scaling given.

A department store chain is expanding into a new market, and is considering 16 different sites on which to locate 4 stores. Assuming that each site is equally likely to be chosen, in how many ways can the sites for the new stores be selected
Assuming that each site is equally likely to be chosen, there are 1820 ways the sites for the new stores can be selected.
The department store chain is planning to expand into a new market and is considering 16 different sites on which to locate 4 stores. In order to determine the number of ways to select the sites for the new stores, we need to calculate the number of ways to select 4 sites from the 16 available sites. This can be done by using the binomial coefficient "16 choose 4" which is also written as,
16C4 = 16!/(4! * 12!)
Using this formula, we can calculate the number of ways to select 4 sites out of 16 as 1820 ways.
This means that the store chain has 4845 different ways to select the 4 sites from the 16 available sites assuming each site is equally likely to be chosen.

Answer:
The length of the third side (Hypotenuse) is 7.1556411313
Step-by-step explanation:
In order to find the third side(Hypotenuse) we use a formula called the phytogorean theorem which was invented by a philosopher named Pythagoras.
[tex]a^{2} +b^{2} =c^{2}[/tex]
We now apply the given values to the equation
[tex]5.96^{2} + 3.96^{2} = c^{2}[/tex]
Squaring the numbers we get,
[tex]35.5216+15.6816 = c^{2}[/tex]
[tex]51.2032[/tex] [tex]= c^{2}[/tex]
We now find the root of the number to find the hypotenuse which is,
[tex]\sqrt{51.2032} = c[/tex]
[tex]7.1556411313 = c[/tex]
Hence , the length of the third side (Hypotenuse) is 7.1556411313
