Answer:
n = 2
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] (n - 4) - 3 = 3 - (2n + 3) ← distribute parenthesis on both sides
[tex]\frac{1}{2}[/tex] n - 2 - 3 = 3 - 2n - 3 ( simplify both sides )
[tex]\frac{1}{2}[/tex] n - 5 = - 2n ( multiply through by 2 to clear the fraction )
n - 10 = - 4n ( add 4n to both sides )
5n - 10 = 0 ( add 10 to both sides )
5n = 10 ( divide both sides by 5 )
n = 2

When Ibuprofen is given for fever to
children 6 months of age up to 2 years, the
usual dose is 5 milligrams (mg) per kilogram
(kg) of body weight when the fever is under
102.5 degrees Fahrenheit. How much
medicine would be usual dose for a 18
month old weighing 21 pounds?
milligrams
Round your answer to the nearest milligram.
Answer: The usual dose for an 18-month-old weighing 21 pounds is 48 mg of ibuprofen.
Step-by-step explanation: To find the usual dose of ibuprofen for a child, we need to follow these steps:
Convert the child’s weight from pounds to kilograms. One pound is equal to 0.4536 kilograms, so we multiply 21 by 0.4536 to get 9.5256 kilograms.Multiply the child’s weight in kilograms by the dose per kilogram. The dose per kilogram is 5 mg when the fever is under 102.5 degrees Fahrenheit, so we multiply 9.5256 by 5 to get 47.628 mg.Round the result to the nearest milligram. To round a number to the nearest milligram, we look at the digit after the decimal point. If it is 5 or more, we add one to the digit before the decimal point and drop the rest. If it is less than 5, we keep the digit before the decimal point and drop the rest. In this case, the digit after the decimal point is 6, which is more than 5, so we add one to the digit before the decimal point and drop the rest. The result is 48 mg.Therefore, the usual dose for an 18-month-old weighing 21 pounds is 48 mg of ibuprofen. Hope this helps, and have a great day! =)
Given cosθ = 2/5 and angle θ is in Quadrant IV, what is the exact value of sinθ in simplest form? Simplify all radicals if needed.
The exact value of sinθ in simplest form, with cosθ = 2/5 and θ in Quadrant IV, is -√21/5.
To find the exact value of sinθ, we can use the Pythagorean identity: sin²θ + cos²θ = 1. Since we know the value of cosθ, we can substitute it into the equation and solve for sinθ.
Given that cosθ = 2/5 and θ is in Quadrant IV, we know that the cosine is positive in Quadrant IV, and the sine is negative. Let's proceed with the calculations:
sin²θ + cos²θ = 1
sin²θ + (2/5)² = 1 (Substituting cosθ = 2/5)
sin²θ + 4/25 = 1 (Simplifying)
sin²θ = 1 - 4/25 (Subtracting 4/25 from both sides)
sin²θ = 21/25 (Simplifying)
Taking the square root of both sides, considering that sinθ is negative in Quadrant IV:
sinθ = -√(21/25)
Since we want to express the answer in simplest form, we can simplify the radical:
sinθ = -√21/√25
The square root of 25 is 5, so we can simplify further:
sinθ = -√21/5
Therefore, the exact value of sinθ in simplest form, given that cosθ = 2/5 and θ is in Quadrant IV, is -√21/5.

The difference of the present ages of the two brothers is 5 years . 6 years ago , if the product of their ages was 696, find the ratio of present age of elder brother and the younger brother.
The present age of the elder brother is in a ratio of 23 to the present age of the younger brother, which can be simplified to a ratio of 5 to 4.
Let's assume the present age of the elder brother is E years, and the present age of the younger brother is Y years. According to the given information, the difference in their ages is 5 years, which can be expressed as E - Y = 5.
Six years ago, the elder brother's age was E - 6, and the younger brother's age was Y - 6. According to the second given condition, the product of their ages at that time was 696, which can be expressed as (E - 6)(Y - 6) = 696.
To find the ratio of their present ages, we need to solve the two equations simultaneously. We can start by expanding the second equation:
(E - 6)(Y - 6) = 696
EY - 6E - 6Y + 36 = 696
EY - 6E - 6Y = 660
Now we can substitute the value of E - Y from the first equation into the second equation:
(E - Y) - 6E - 6Y = 660
5 - 6E - 6Y = 660
-6E - 6Y = 655
Simplifying the equation:
6E + 6Y = -655
Now we have a system of linear equations:
E - Y = 5
6E + 6Y = -655
Solving these equations, we find that the present age of the elder brother (E) is 23 years and the present age of the younger brother (Y) is 18 years.
Therefore, the ratio of the present age of the elder brother to the younger brother is 23:18, which can be simplified to 5:4.

The formula for the volume of a triangular pyramid can be written as V = 1/3 B•h, where B = area of the base. What is the formula for B?
A. B = πr²
B. B=I•w
C. B = ½bh
The formula for the area of the base (B) of a triangular pyramid is given by option C: B = ½bh.
In a triangular pyramid, the base is a triangle, and the area of a triangle is calculated using the formula ½bh, where b represents the length of the base of the triangle and h represents the corresponding height. Therefore, the formula for the area of the base (B) is B = ½bh.
The base of a triangular pyramid is a two-dimensional shape, and its area is determined by the length of the base and the height perpendicular to it. The formula B = ½bh is commonly used to find the area of a triangle, which applies to the base of the pyramid in this case.
The ½ factor accounts for the fact that the base is a triangle, and the product of the base length (b) and the corresponding height (h) yields the area of the triangle. Hence, option C correctly represents the formula for the base area of a triangular pyramid.

Find the 23rd term of an arithmetic sequence where the fourteenth term is 37 and the fifth term is 82.
The 23rd term of the arithmetic sequence is -8.
To find the 23rd term of an arithmetic sequence, we need to know the common difference (d) of the sequence.
Given that the 14th term is 37 and the 5th term is 82, we can use this information to find the common difference.
The formula for the nth term of an arithmetic sequence is:
Term n = a + (n - 1) * d,
where a is the first term and d is the common difference.
Using the information provided, we can set up two equations based on the given terms:
Equation 1: a + (14 - 1) * d = 37, (14th term is 37)
Equation 2: a + (5 - 1) * d = 82. (5th term is 82)
Simplifying the equations, we have:
Equation 1: a + 13d = 37,
Equation 2: a + 4d = 82.
We can solve this system of equations to find the values of a and d. Subtracting Equation 2 from Equation 1, we have:
(a + 13d) - (a + 4d) = 37 - 82,
13d - 4d = -45,
9d = -45,
d = -5.
Now that we have the common difference, we can find the first term (a) using Equation 2:
a + 4d = 82,
a + 4(-5) = 82,
a - 20 = 82,
a = 82 + 20,
a = 102.
Now, we can use the formula for the nth term to find the 23rd term:
Term 23 = a + (23 - 1) * d,
Term 23 = 102 + 22 * (-5),
Term 23 = 102 - 110,
Term 23 = -8

Consider the following matrix in reduced row echelon form:
Row Echelon Form
What can you say about the solution to the associated linear system?
The reduced row echelon form of a matrix allows us to determine whether the associated linear system is consistent or inconsistent, unique or has infinitely many solutions.
In reduced row echelon form, a matrix has the following properties:
Each leading entry (the leftmost nonzero entry) of a row is equal to 1.
Each leading entry is the only nonzero entry in its column.
All entries below a leading entry are zeros.
The leading entry in each row is to the right of the leading entry in the row above it.
Based on these properties, we can make the following conclusions about the solution to the associated linear system:
Consistency: If there are no rows of the form [0 0 ... 0 | b] (where b is a nonzero constant), meaning there are no contradictory equations, the linear system is consistent. In other words, there is at least one solution.
Uniqueness: If there are no free variables (columns without leading entries), meaning each column corresponds to a pivot column, the linear system has a unique solution. This means there is only one set of values for the variables that satisfies all the equations.
Infinite solutions: If there are one or more free variables, the linear system has infinitely many solutions. This occurs when there are more variables than equations or when there are dependent equations.
The reduced row echelon form provides an organized representation of the linear system that simplifies the process of determining its solution. By analyzing the structure of the matrix, we can determine the consistency, uniqueness, and the nature of the solution set.

Peter is going to visit 5 cities this summer. He will choose from 7 different cities, and the order in which he visits the cities does not matter. How many different city combinations are possible for the summer traveling?
There are 21 different city combinations possible for Peter's summer traveling.
To determine the number of different city combinations possible for Peter's summer traveling, we need to calculate the number of combinations of choosing 5 cities out of the 7 available cities.
Since the order in which he visits the cities does not matter, we are dealing with combinations rather than permutations.
The formula to calculate the number of combinations is given by the binomial coefficient, also known as "n choose k," denoted as C(n, k) or (nCk).
In this case, we have 7 cities to choose from, and Peter will visit 5 cities. Thus, we can calculate the number of city combinations as follows:
C(7, 5) = 7! / (5! * (7-5)!)
= 7! / (5! * 2!)
= (7 * 6 * 5!) / (5! * 2)
= (7 * 6) / 2
= 42 / 2

The measure of angle Q is equal to 70 degrees.
What is a parallelogram?In Mathematics and Geometry, a parallelogram is a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.
Generally speaking, the the sum of all the interior angles of a parallelogram is equal to 360 degrees and as such, we have the following:
(6x+4) + (6x+4) + 10x + 10x = 360
32x + 8 =360
32x =360-8
32x=352
x = 11
Now, we can determine the measure of angle Q as follows;
Q = 6x + 4
Q = 6(11) + 4
Q = 66 + 4
Q = 70 degrees.
