If it is suggested that people of age, less than or equal to 18 years and of age, greater than or equal to 50 years, should be the first to get a flu vaccine, then we can define a variable "A" to the age group suggested to be prioritized for to vaccinate with the flu vaccine, and the compound inequality to describe the situation can be written as [(A ≤ 18) or (A ≥ 50)].
As per the question statement, it is suggested that people of age, less than or equal to 18 years and of age, greater than or equal to 50 years, should be the first to get a flu vaccine.
We are required to define a variable to the age group suggested to be prioritized for to vaccinate with the flu vaccine, and describe the question mentioned situation in the form of a compound inequality.
To start with, let us first determine the variable. It is as simple as assuming any alphabet, say "A", to be the age group, suggested to be prioritized for to vaccinate with the flu vaccine.
Since, suggested that people of age, less than or equal to 18 years should be amongst the the first to get a flu vaccine, thus "A" must be less than equal to 18, i.e., [tex][A\leq 18][/tex]...(1)
Similarly, suggested that people of age, greater than or equal to 50 years should be amongst the the first to get a flu vaccine, thus "A" must be greater than equal to 50, i.e., [tex][A\geq 50][/tex]...(2)
Now, combining (1) and (2), we get our required compound inequality to be [(A ≤ 18) or (A ≥ 50)].
Compound Inequality: In mathematics, a compound inequality is an inequality that combines or "compounds" two simple inequalities with an "or" in the middle.To know more about compound inequality, click on the link below.

The geometric mean of a number and four times the number is 22 . What is the number?
If 22 is the geometric mean of a number and four times the number, then the number is 11.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Let x = x1 = unknown number
y = x2 = four times the number = 4x
Using the formula in solving geometric mean, plug in the values and variables.
GM = n√x1 x2 . . . xn
22 = √xy
22 = √x(4x)
22 = √4x^2
22 = 2x
x = 11
y = 4x
y = 44
Hence, the number is 11. 22 is the geometric mean of 11 and 44.

Jan and Dinah both ran for 20 seconds, each at a constant speed. Jan ran 50 mefers and Dingh ran 60 meters. 1. Who was moving faster? Explain how you know. 2. How far did each person move in 1 second?
By calculating speed of each person we can find who is faster.
What is Speed?Speed can be defined as the distance covered with respect to time. It is a scalar quantity. It is calculated as follows
Speed = Distance / Time taken
The time taken by each person is 20 seconds.
Distance covered by Jan = 50 meter
Speed of Jan = Distance / Time taken
Speed of Jan = 50 / 20
Speed of Jan = 2.5 meters per second
Distance covered by Dingh = 60 meter
Speed of Dingh = Distance / Time taken
Speed of Dingh = 60 / 20
Speed of Dingh = 3 meters per second
Since the speed of Dingh is more than Jan, we can say that Dingh is faster.
Distance = Speed × Time taken
Here, time taken = 1 second
This implies Distance Covered = Speed
Therefore, Jan covers 2.5 meters in one second while Dingh covers 3 meters in one second.

5n - 7n = 14
Please show the step by step process! (:
Answer: n=-7
Step-by-step explanation:
5n - 7n = 14
(5-7)n=14
-2n=14
-2n/(-2)=14/(-2)
n=14/(-2)
n=-7
The equation is,
→ 5n - 7n = 14
Solving for the value of n,
→ 5n - 7n = 14
→ -2n = 14
→ n = -(14//2)
→ [ n = -7 ]
Thus, the value of n is -7.

2|2x+3|=|x-3|
There should be two solutions.
Please show the steps and give an explanation on how to solve it and why.
Answer:
x= -3
Step-by-step explanation:
[tex]2(2x + 3) = x - 3 \\ 4x + 6 = x - 3 \\ 4x = x - 3 - 6 \\ 4x - x = - 3 - 6 \\ 3x = - 9 \\ x = \frac{ - 9}{3} \\ x = - 3[/tex]
Answer:
[tex]x=-3 \textsf{ \quad or \quad} x=-\dfrac{3}{5}[/tex]
Step-by-step explanation:
Given absolute value equation:
[tex]2|2x+3|=|x-3|[/tex]
The absolute value of a number is its positive numerical value.
Therefore, the expressions inside the bars should be set to both positive and negative. Rewrite the absolute value equation as four equations without absolute value bars and simplify:
[tex]\textsf{Positive = Positive}: \quad 2(2x+3)=x-3[/tex]
[tex]\textsf{Positive = Negative}: \quad 2(2x+3)=-(x-3)[/tex]
[tex]\begin{aligned}\textsf{Negative = Positive}: \quad -2(2x+3) &=x-3\\ \implies 2(2x+3) &=-(x-3)\end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Negative = Negative}: \quad -2(2x+3) &=-(x-3)\\ \implies 2(2x+3)&=x-3\end{aligned}[/tex]
From inspection of the equations:
Positive = Positive is equal to Negative = Negative, and Negative = Positive is equal to Positive = Negative,so there are only two unique equations to be solved.
Equation 1
[tex]\begin{aligned}2(2x+3) & =x-3\\4x+6 & = x-3\\4x+6-x&=x-3-x\\3x+6&=-3\\3x+6-6&=-3-6\\3x & =-9\\\dfrac{3x}{3} & = \dfrac{-9}{3}\\ x&=-3 \end{aligned}[/tex]
Equation 2
[tex]\begin{aligned}2(2x+3)&=-(x-3)\\4x+6&=-x+3\\4x+6+x&=-x+3+x\\5x+6&=3\\5x+6-6&=3-6\\5x &=-3\\ \dfrac{5x}{5}&=\dfrac{-3}{5}\\x &=-\dfrac{3}{5} \end{aligned}[/tex]
Therefore, the solutions are:
[tex]x=-3 \textsf{ \quad or \quad} x=-\dfrac{3}{5}[/tex]

A pendulum moving in simple harmonic motion is modeled by the function , where s is measured in inches and is measured in seconds. determine the first time when the distance moved is 4 inches.
The maximum displacement, the frequency, and the time required for one cycle are 1/5 inch, 1/π Hz and π sec.
What is displacement?A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions. It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.
Therefore, the instantaneous speed is different from velocity, which is the rate at which the distance traveled along a particular path changes over time. The temporal rate of change of the position vector can also be used to describe velocity.

WHAT ARE LINEAR EQUATION ?There is only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All the points fall on the same line when the values that together make a linear equation true are determined and plotted on a coordinate grid.
CALCULATIONLet n represent nickels & d dimes
given: n + d = 25 #1 (number of coins)
given: .05n + .10d = 1.65 #2 (amount in dollars)
n = 25 - d #3 (rewrite of #1)
.05(25 -d) + .10d = 1.65 (substitute #3 in #2)
1.25 - .05d + .10d = 1.65 (multiply out the left side)
.05d = .40 (collection of like terms)
d = 8 (divided both sides by.05)
n + 8 = 25 (substitute answer for d in #1)
n = 17 (subtract both sides by 8)

In this question we must transform a quantity in a unit to another quantity in a unit of the same kind. For instance, if we have a quantity in a mass unit, then we only can convert it into another mass unit.
Herein we have four unit conversion cases for volumes, both pints and quarts are volume units commonly used in the United States. There are the following equivalencies:
1 quart = 2 pints = 4 cups = 32 fluid ouncesNow we proceed to convert each quantity to pints and quarts by cross multiplication:
a) 32 fl oz × 2 pints / 32 fl oz = 2 pints, 32 fl oz × 1 qt / 32 fl oz = 1 qt
b) 24 c × 2 pints / 4 c = 12 pints, 24 c × 1 qt / 4 c = 6 qt
c) 10 c × 2 pints / 4 c = 5 pints, 10 c × 1 qt / 4 c = 2.5 c

A Figure ABCD is a rhombus. The angles of A and C are equal by alterenate interior angle. The value of x in the figure ABCD rhombus is 9 degree.
What is a rhombus?We know that rhombuses are a particular type of quadrilateral in Euclidean geometry. It is a unique instance of a parallelogram in which the diagonals meet at a 90-degree angle and all sides are equal.
The Solution to an equation is finding values of the variable in the considered equation for which the equation considered evaluates to be true.
For a solution, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, thus solution to a system is the intersection of all its equation at single point
WE know that the diagonals of a rhombus bisect each other, we know that triangle DEC is a right triangle.
Since the side lengths of a rhombus are equal, so the angles of A and C are equal by alterenate interior angle.
Now, 5x-8 = 3x + 10
i.e. 5x - 3x = 10 + 8
i.e. 2x = 18
