Answer:
x = 3
Step-by-step explanation:
5x + 1 = 2x + 10
1.) Subtract 2x from both sides to get 2x on the other side
5x - 2x + 1 = 10
2.) Subtract 1 from both sides to get 1 to the other side
5x - 2x = 10 - 1
3.) Combine like terms
3x = 9
4.) Divide 3 on each side to get x by itself
x = 3

What is 0900 military time?
0900 military time is 9:00 AM in the 24-hour time format used by the military, also known as the 24-hour clock.
The 24-hour clock is a timekeeping system that uses a continuous count of 24 hours, instead of two sets of 12 hours for AM and PM. In this system, each hour of the day is numbered from 0 to 23, and is referred to as "military time" or "24-hour time". So, 0900 military time is equivalent to 9:00 AM, with the "0" indicating the first hour of the day. This system is commonly used in the military, as well as in other fields where precise and standardized timekeeping is important, such as aviation and public transportation.

A company is designing a new cylindrical package. The volume of the package is 87.92 in.3. The radius is 2 inches. Use the formula V = Bh and 3.14 to approximate π
to answer the questions.
Part A
To the nearest inch, how many inches is the height of the cylindrical package?
Part B
The company decides to keep the radius the same and double the height. Rounded to the nearest hundredth, how many cubic inches is the new volume of the package?
The height of the cylinder is 7 inches and the the new volume of the package is 175.84 cubic inches
What is the height of the cylindrical package1. The formula for the volume of a cylinder is V = Bh, where B is the base area and h is the height. The base of the cylinder is a circle, and the formula for the area of a circle is A = πr^2.
Substituting the given values into the formula for the volume of a cylinder, we get:
87.92 = πr^2h
87.92 = 3.14(2^2)h
87.92 = 12.56h
h = 87.92/12.56
h ≈ 7
Rounding to the nearest inch, the height of the cylindrical package is 7 inches.
Part B:
If the company doubles the height while keeping the radius the same, the new height will be 2h. Therefore, the new volume will be:
V = πr^2(2h) = 2πr^2h
Substituting the given values into this formula, we get:
V = 2(3.14)(2^2)(2h)
V = 25.12h
To find the new volume, we need to substitute the value of h from Part A into this formula:
V = 25.12(7)
V ≈ 175.84
Rounding to the nearest hundredth, the new volume of the package is 175.84 cubic inches.

The length of the sides of a triangle is 15cm, ycm and (y-2)cm. If the area is less than 80cm2(square).Find the possible values of y
Answer:
We can use Heron's Formula to calculate the area of a triangle given its three side lengths. The formula is:
A = √(s*(s-a)*(s-b)*(s-c)),
where s = (a + b + c)/2, a, b and c are the three sides of the triangle.
In this case, a = 15, b = y and c = (y-2). Therefore, we can plug these numbers in to get:
80 > √[(y + 7.5) * (y - 7.5) * (y - 2) * (y - 15)]
We can simplify this equation to get:
y^2 - 5y - 80 > 0
This equation can be solved using the quadratic formula, where the solution for y is:
y < 14.09 or y > 10.91
Therefore, the possible values for y are any number between 10.91 and 14.09.

The spring compressed in stopping the ore car is 4.4719 m.
For answer this we will apply the rule of the conservation of energy,
The conservation of energy principle states that in a closed system, the energy of interacting objects or particles remains constant. Kinetic energy, sometimes known as the energy of motion, was the first type of energy to be identified. The total of the kinetic energy of the particles before collision and the sum of the kinetic energy of the particles after collision are identical in some particle collisions, known as elastic collisions.
where:
[tex]E_i=E_f[/tex]
First, we will call:
[tex]E_i[/tex]:the automobile is parked
[tex]E_f[/tex]:when the spring is shortened
so:
[tex]E_i=E_f[/tex]
[tex]mgh=\frac{1}{2}kx^2[/tex]
where M is the vehicle's mass, g is gravity, h is height, K is the spring's constant, and X is the compressed spring used to halt the ore car. By substituting values, we obtain:

range is 39 years. Find the ages of the five family members.
The ages of the five family members as required are; 3, 10, 13, 42 and 42.
What are the ages of the five family members?As evident, in the task content, let a, b , c , d , e represents the ages of the family members in ascending order.
Since the median of the ages is; 13, it follows that the the third term, c = 13.
Also, since the mode is 42, it follows that; d = e = 42.
Also, since the range of the ages is 39, it follows that; 42 - a = 39 and consequently a = 3.
Finally, since the mean age is 22; it follows from the mean formula that;
22 = ( 3 + b + 13 + 42 + 42 ) / 5
110 = b + 100
b = 10.
Ultimately, the ages of the five family members as required are; 3, 10, 13, 42 and 42.

Find the eigenvalues and eigenvectors of matrix A = 5 4
1 2
The matrix A eigenvalues and eigenvectors are as follows:
Eigenvalue λ1 = 1 with eigenvector v1 = [1, -1]
Eigenvalue λ2 = 6 with eigenvector v2 = [4, 1]
Using the equation (A - λI)v = 0, where is an eigenvalue of A, I am the 2x2 identity matrix, and v is the associated eigenvector, we can determine the eigenvalues and eigenvectors of the matrix A = [[5, 4], [1, 2]].
First, we calculate the (A - λI) matrix's determinant:
det(A - λI) = |5-λ 4| = (5-λ)(2-λ) - 4 = λ^2 - 7λ + 6
|1 2-λ|
We obtain the characteristic equation by setting the determinant to zero:
λ^2 - 7λ + 6 = 0
We obtain two eigenvalues after solving for λ :
λ = 1 and λ = 6
Next, For each eigenvalue, we identify the appropriate eigenvectors:
For λ = 1, We solve the system of linear equations represented by the equation(A - λI)v = 0:
4v1 + 4v2 = 0
v1 + v2 = 0
The second equation is evidently as straightforward as v1 = -v2. When we enter this into the initial equation, we get:
4v2 - 4v2 = 0
Thus, the eigenvector for λ = 1 is v = [1, -1].
For λ = 6, We solve the system of linear equations represented by the equation(A - λI)v = 0:
-v1 + 4v2 = 0
-v1 + 4v2 = 0
v1 - 4v2 = 0
It is evident that the first equation is just v1 = 4v2. When we enter this into the second equation, we get:
4v2 - 4v2 = 0
Thus, the eigenvector for λ = 6 is v = [4, 1].
Therefore, The matrix A eigenvalues and eigenvectors are as follows:
Eigenvalue λ1 = 1 with eigenvector v1 = [1, -1]
Eigenvalue λ2 = 6 with eigenvector v2 = [4, 1]

What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

What is the probability of obtaining 3 heads in four flips of a fair coin?
The probability of obtaining 3 heads in four flips of a fair coin is 1/4.
The probability of obtaining 3 heads in four flips of a fair coin can be calculated using the binomial probability formula. The formula is:
[tex]P(X = k) = (n choose k) * p^k * (1 - p)^{(n - k)}[/tex]
where P(X = k) is the probability of obtaining k successes (in this case, 3 heads), and n is the total number of trials (in this case, 4 flips).
p is the probability of success on a single trial (in this case, 0.5 since the coin is fair), and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.
Plugging in the values, we get:
[tex]P(X = 3) = (4 choose 3) * 0.5^3 * (1 - 0.5)^{(4 - 3)}[/tex]
= 4 * 0.125 * 0.5
= 0.25

Calculating antiderivatives, definite line integrals, double and triple integrals, and improper integrals is made easy using Wolfram | Alpha.
Wolfram| | Alpha does integral computations differently than people. It uses the Integrate function in Mathematica, which is the result of much mathematical and computational study. Integrate does integrals differently than individuals do. Instead, it makes use of robust, broad algorithms, which frequently need quite complex arithmetic. One includes determining an integral's general form, differentiating this form, and then resolving equations to match ambiguous symbolic parameters. The equations produced in this technique can be quite complicated, even for relatively basic integrands, and are best solved using Mathematica's robust algebraic computation capabilities. Converting integrals to generalized hypergeometric functions and then using collections of relations about these extremely complex mathematical functions is another method Mathematica utilizes to calculate integrals.
