Fourteen percent of the town's population is over the age of 65. If there are 322 residents over the age of 65, approximately what is the town's population?
If 14 percent of the town's population is over the age of 65 and there are 322 residents over the age of 65, then the population of the town is 2300
The percentage of people over the age of 65 = 14%
Number of residents over the age of 65 = 322
Consider the total population of the town as x
Then the equation will be
x × (14/100) = 322
From this equation we have to find the value of x, that is the population of the town.
x × (14/100) = 322
x × 0.14 = 322
x = 322/0.14
x = 2300
Hence, if 14 percent of the town's population is over the age of 65 and there are 322 residents over the age of 65, then the population of the town is 2300

A recipe book shows measurement conversions for pints to cups. It shows that 1.5 pints equals 3 cups and 2.5 pints equals 5 cups.
Write an equation that shows the proportional relationship between pints and cups where p represents pints and n represents cups.
p equals 3 over 1.5 times n
n equals 1.5 over 3 times p
p = 0.5n
n = 0.5p
The equation that shows the proportional relationship between pints and cups where p represents pints and n represents cups is p = 0.5n
How to calculate the value?From the information, the recipe book shows measurement conversions for pints to cups. It shows that 1.5 pints equals 3 cups and 2.5 pints equals 5 cups.
p = pints
n = cups.
Therefore, the equation will be illustrated as

Ken is building a deck. He determined that he needs 25 blocks that cost $7.97 each and 48 deck boards that cost $14.00 each. How much will Ken pay for these items?
Ken will pay $ 871.25 for these items
Explanation
to find the total cost we need add the cost of the blocks to the cost of the total boards, so
Step 1
find the total cost of the blocks
a) when having the cost per unit and the amount, we just need to do a multiplication, so
[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the blocks= 7.97}\frac{\text{ \$}}{block}*25\text{ Blocks} \\ tota\text{l cost of the blocks= \$ 199.25} \end{gathered}[/tex]Step 2
now, the total cost of the boards:
[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the boards= 14}\frac{\text{ \$}}{board}*4\text{8 boards} \\ tota\text{l cost of the boards= \$ 672} \end{gathered}[/tex]Step 3
finally, add the costs to find the total
[tex]\begin{gathered} total\text{ cost= \$199.25+672} \\ total\text{ cost= 871.25} \end{gathered}[/tex]therefore, Ken will pay $ 871.25 for these items

-2×+5y=-13×+2y=11[tex] - 2 \times + 5y = - 1[/tex]
nealmiyasmith20, this is the solution:
-2× + 5y= -1
3× + 2y= 11
___________
Step 1: Isolating x on the first equation:
-2× + 5y= -1
-2x = - 1 - 5y
Dividing by -2 at both sides:
-2x/-2 = -1/-2 - 5y/-2
x = 1/2 + 5y/2
______________________
Step 2: Substituting x and solving for y on the second equation:
3× + 2y = 11
3 ( 1/2 + 5y/2) + 2y = 11
3/2 + 15y/2 + 2y = 11
19y/2 = 11 -3/2
19y/2 = 19/2
Multiplying by 2/19 at boths sides:
19y/2 *2/19 = 19/2 * 2/19
y = 1
___________________
Step 3: Substituting y and solving for x on the first equation:
-2× + 5y = -1
-2x + 5 * 1 = -1
-2x + 5 = -1
-2x = -1 - 5
-2x = -6
Dividing by -2 at both sides:
-2x/-2 = -6/-2
x = 3
Step 4: Proving that x = 3 and y = 1 are correct on the second equation:
3× + 2y = 11
3 * 3 + 2 * 1 = 11
9 + 2 = 11
11 = 11
We proved that x = 3 and y = 1 are correct

By using free body diagrams and trigonometric relations, the normal force of the block of iron has a magnitude of 352.579 newtons.
What is the normal force of the block of iron?
In accordance with the third Newton's law, normal forces (N), in newtons, are reactive forces as the result of the contact of the iron mass with the ground of the incline, that is to say, the normal force is the reaction of the weight of the iron mass (W), in newtons. If the iron mass is at rest, then we find the following free body diagram of the ground-mass system and its related geometric system.
Since the free body diagram represents a three force system, then the magnitude of the normal force is found by trigonometric relations:
N = W · cos 26°
N = (40 kg) · (9.807 m / s²) · cos 26°
N = 352.579 N
The normal force of the block of iron has a magnitude of 352.579 newtons.

Given the line h(x), it can be observed that two points with coordinate below can be located

For example, if m1 is the slope of a line, the slope of its parallel line would be m1. But the slope of the perpendicular line would be -1/m1
The slope of the line that would be parallel to h(x) is the same as the slope of h(x)
The slope of the line that would be perpendicular to h(x) would be negative inverse of the slope of line h(x)
[tex]\begin{gathered} s_{\text{parallel}}=-\frac{1}{8} \\ s_{\text{perpendicular}}=\frac{-1}{-\frac{1}{8}}=-1\times\frac{-8}{1}=8 \end{gathered}[/tex]Hence, The slope of the line that would be parallel to h(x) is -1/8, while the slope of the line that would be perpendicular to h(x) is 8

[tex][/tex]There is a game where the outcome is a random integer from 1 to 50. If the outcome is odd, you wi $26. If the outcome is even, you win nothing. If you play the game, what is the expected payoff?
We have a game like the one described in the question and we have to calculate the expected payoff, which is equal to the sum of the possible outcomes weighted by the probability of that outcome.
In this case we have two outcomes:
1) We get an odd number and we win $26 (W=26).
2) We get an even number and we get $0 (W=0).
To calculate the probabilities of each oucome we have to know the proportion of odd an even numbers in the list of 1 to 50. We have a total of 50 numbers, rom which 25 are odd numbers and 25 are even numbers, so the probability of each outcome can be calculated as the relative frequency of each category:
[tex]\begin{gathered} P_1=\text{ number of odds / total numbers}=\frac{25}{50}=0.5 \\ P_2=\text{ number of evens / total numbers}=\frac{25}{50}=0.5 \end{gathered}[/tex]Then, we can calculate the expected payoff as:
[tex]E=\sum ^n_{i=1}p_iW_i=p_1W_1+p_2W_2=0.5\cdot26+0.5\cdot0=13+0=13[/tex]p_i: probability of outcome i.
W_i: prize when outcome i happens.

Answer: the expected payoff for this game is $13.
Order of operations was it evaluated correctly? 5^(2) + 1^(2) = 6(2) = 36EXPLAIN your reasoning. Thank you
The answer to the operation is as follows:
5^(2) + 1^(2) = 5*5 + 1*1 = 25 + 1 = 26.
Here, we have to remember PEMDAS. First, we solve parentheses, then exponents (or exponentiation operations); then, multiplications, divisions, and, after all this, addition and subtractions.
In the above operation, we solve first the raising of 5 to 2, then 1 raised to 2. We sum the result of both operations. So the value of 36 is not correct. The correct value is 26.

On a coordinate plane, a line goes through points (0, 16) and (6, 0).
The graph that represents the linear equation, 24x + 64y = 384 is shown in the diagram.
How to Determine the Graph of a Linear Equation?A linear equation can be expressed as y = mx + b, which is the slope-intercept form where the slope is represented as m and the y-intercept is represented by b. This y-intercept is the point where the line intercepts the y-axis when x is equal to zero.
Given the linear equation, 24x + 64y = 384, rewrite in slope-intercept form to easily figure out the slope:
24x + 64y = 384
64y = -24x + 384
y = -24x/64 + 384/64
y = -6/16x + 6
This shows that the graph would have a y-coordinate, b = 6, while the slope is -6/16. The graph would be the one shown below in the diagram.

Answer:

Step-by-step explanation:
Solve each expression by completing the square. x^2+6x=9
x^2+6x=9
To create a trinomial square on the left side of the equation, you have to find a value that is equal to the square of half of 9.
(9/2)^2=(3)^2
Then, add this therm to each side of the equation.
x^2+6x+(3)^2=9+(3)^2
Simplifying that equation:
x^2+6x+9=18
Factor the perfect trinomial square into (x+3)^2
(x+3)^2=18
To solve the equation for x, you have to take the square root of each side of the equation:

The solution of a system of linear equations is the point where the two lines meet. Note that for the given equations, both lines have the same slope (4/5). If two lines have the same slope, it means that those lines are parallel. Parallel lines do not meet at any point, they stay parallel to the infinite.
Therefore, since this two lines are parallel, they don't meet and the system has no solution.
