Answer:
80 lemons
Step-by-step explanation:
Let x represent the amount of lemons that were on the tree.
We can use this to set up an equation:
\(40\%x=32\)
Note that percentages can also be written as that number over 100.
\(\frac{40}{100}x=32\)
Simplify the fraction.
\(\frac{2}{5}x=32\)
Multiply both sides by 5
\(2x=160\)
Divide both sides by 2
\(x=80\)
There were 80 lemons on the tree before he picked the lemons.
you are to build a rectangular pen with three parallel partitions using 500 feet of fencing. what dimensions will maximize the total area of the pen?
The dimensions required are 125 feet and 50 feet.
The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the "instantaneous rate of change", the ratio of the instantaneous change in the dependent variable to that of the independent variable. Derivatives can be generalized to functions of several real variables. In this generalization, the derivative is reinterpreted as a linear transformation whose graph is (after an appropriate translation) the best linear approximation to the graph of the original function. The Jacobian matrix is the matrix that represents this linear transformation with respect to the basis given by the choice of independent and dependent variables.
The total length will be x and the height will be y.
Perimeter = 500 = 2x + 5y
Total Area = A = xy
Solve for y using the equation of perimeter:
5y = 500 - 2x
y = 100 - 2x/5
Put y in the equation of the Area
A = x(100 - 2x/5)
A = -2x²/5 +100x
To find the maximum area, find the derivative:
A' = -4x/5 + 100
To maximise the area, we equate A' to zero.
A' = 0
-4x/5 +100 = 0
∴ x = 125
A' is positive when x < 125 and A' is negative when x >125, therefore meaning that x=125 is a maximum. Since this value is a maximum, the area is maximized when the total length is 125ft.
Put x = 125 in equation of perimeter:
500 = 2(125) + 5y
500 = 250 + 5y
5y = 250
∴ y = 50 ft
Thus, the dimensions required are 125 feet and 50 feet.

The completion times for a 10K race among all males ages 20-24 years old are normally distributed with a mean of 52 minutes. Furthermore, 60% of all male runners in this age group have a 10K completion time of less than 53 minutes. What is the missing standard deviation for the 10K completion times of all males in this age group?
The percentage of runners completing the race in under 53 minutes. With a mean completion time of 52 minutes, the missing standard deviation is approximately 1.28 minutes.
Given that the completion times for the 10K race among all males ages 20-24 are normally distributed with a mean of 52 minutes, we can use the concept of standard deviations to determine the missing value.
Let's assume the standard deviation is denoted by σ. Since 60% of male runners in this age group complete the race in under 53 minutes, we can interpret this as the percentage of runners within one standard deviation of the mean. In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. Therefore, we have:
P(X < 53) ≈ 0.60
Using the standard normal distribution table or calculator, we can find the corresponding z-score for this probability, which is approximately 0.253. The z-score is calculated as (X - μ) / σ, where X is the observed value, μ is the mean, and σ is the standard deviation. In this case, X is 53, μ is 52, and the z-score is 0.253.
Now, we can solve for the standard deviation σ:
0.253 = (53 - 52) / σ
Simplifying the equation, we get:
0.253σ = 1
Dividing both sides by 0.253, we find:
σ ≈ 1.28
Therefore, the missing standard deviation for the 10K completion times of all males ages 20-24 is approximately 1.28 minutes.

======================================================
Work Shown:
As you mentioned, we'll use Pythagoras' Theorem aka Pythagorean Theorem.
\(a^2+b^2 = c^2\\\\(x+3)^2+(4(x+2))^2 = 25^2\\\\(x+3)^2+16(x+2)^2 = 625\\\\(x^2+6x+9)+16(x^2+4x+4) = 625\\\\x^2+6x+9+16x^2+64x+64 = 625\\\\17x^2+70x+73 = 625\\\\17x^2+70x+73-625 = 0\\\\17x^2+70x-552 = 0\\\\\)
Next, we'll use the quadratic formula with a = 17, b = 70, c = -552.
\(x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-70\pm\sqrt{(70)^2-4(17)(-552)}}{2(17)}\\\\x = \frac{-70\pm\sqrt{42436}}{34}\\\\x = \frac{-70\pm206}{34}\\\\x = \frac{-70+206}{34} \ \text{ or } \ x = \frac{-70-206}{34}\\\\x = \frac{136}{34} \ \text{ or } \ x = \frac{-276}{34}\\\\x = 4 \ \text{ or } \ x \approx -8.1176\\\\\)
Ignore the negative x value solution. The sides (x+3) and 4(x+2) will be negative values if we plugged in x = -8.1176, but negative side lengths do not make sense.
This makes x = 4 the only possible solution.

a) third degree trinomial
b) fourth degree trinomial
c) sixTh degree polynomial
d) first degree binomial
can some one plss help me??
Answer:
a) third degree trinomial
Step-by-step explanation:
The degree of a polynomial is the same as the degree of the term of the polynomial with the highest degree. The degree of a term is the sum of all the exponents of the variables of the term. Remember that a variable such as x, or y, or z has degree 1.
Now we look at the degree of each term:
2x: degree 1 (since x is the same as x^1)
10x^2: degree 2
-x^3: degree 3
The term with highest degree is the last term which has degree 3, so the degree of the polynomial is 3.
The polynomial has 3 terms, so it is a trinomial.
Answer: a) third degree trinomial
the table below shows the number of years of experience that 8 employees at a supermarket have and their hourly wages
Answer:
A. See attachment 1.
B. See attachment 2.
C. As the number of years of experience increases, so does the hourly wage.
Step-by-step explanation:
Part AWhen creating a scatter plot with bivariate data:
The explanatory (independent) variable is drawn on the x-axis.The response (dependent) variable is drawn on the y-axis.For the given data, the hourly wage is dependent on the number of years of experience. Therefore:
Years of experience is the explanatory variable and so is drawn on the x-axis.Hourly wage is the response variable and so is drawn on the y-axis.Draw the scatter plot
Label the x-axis "Years of experience".Label the y-axis "Hourly wage (in dollars)".Use a scale of x : y = 1 : 2 since there are 14 squares along the y-axis, yet the greatest y-value is 15. Plot the data from given table.(See attachment 1).
Part BDraw a line of best fit on the scatter plot (see attachment 2).
Part CCorrelation measures how closely two variables are linked.
If two variables are correlated, you can draw a line of best fit on the scatter plot.
The line of best fit has a positive slope and is close to the data points.
Therefore, the scatter plot shows a strong positive correlation between the years of experience and the hourly wage.
This suggests that as the number of years of experience increases, so does the hourly wage.

y = 25x + 128.8
Step-by-step explanation:
y = total cost
x = amount of days the car was rented
25 represents the daily charge for the fee and the insurance (15+10=25)
128.8 represent the cost for miles driven by Jerry
This was calculated by multiplying the amount of miles he drove (644) by the cost of each mile (.20)
644x.20=128.8 so the cost for miles driven is $128.8 which is why it was added to the equation
I NEED HELP ASAP!!! please answer
Based on the calculation, it should be noted that the solution to the system of equations is x = 5.
How to solve the equationTo represent the costs (C) in dollars for x number of nights, we can use the equation:
C(x) = $500 (one-time preparation cost) + $10 (daily utility cost) * x (number of nights).
R(x) = $110 (rent per night) * x (number of nights).
Now, let's find the solution to the system of equations, which means finding the value of x where the costs equal the revenue:
C(x) = R(x)
Substitute the expressions for C(x) and R(x):
$500 + $10x = $110x.
To solve for x, we can move all the terms involving x to one side:
$110x - $10x = $500.
Combine like terms:
$100x = $500.
Now, divide both sides by 100 to isolate x:
x = $500 / 100.
x = 5.
The solution to the system of equations is x = 5.

One cube has edges n meters long. Another has edges 3n meters long. What is the ratio of the volume of the first cube to the volume of the second cube
Answer:
1:3
Step-by-step explanation:
The second cube is 3x bigger than the first cube, and since all sides of a cube are the same the ratio for the length of the edges will directly transfer over to the ratio of their volumes.
C. 1 : 27
As an example, let's say that n is equal to 1. The volume of the first cube is n*n*n, since n stands for the measurement of each edge. n*n*n=1*1*1=1 cubic meter. Now, onto the second cube. The volume of the second cube is 3n*3n*3n, since 3n stands for the measurement of each edge. 3n*3n*3n=3*3*3 ( since 3n=3*1=3 ) which is equal to 27. The ratio of the volume of the first cube to the volume of the second cube is represented by n : 3n. Substituting the n on both sides for the n in our example, we get a final result and ratio of 1 : 27.
what does it mean to say that an allele is "fixed"?
Answer:
When we say that an allele is "fixed," it means that a particular allele has reached a frequency of 100% in a population.
Step-by-step explanation:
Alleles are different forms of a gene that occupy the same position on homologous chromosomes. In a population, different alleles can exist for a specific gene. However, through various evolutionary processes such as natural selection, genetic drift, or gene flow, one allele may become predominant and eventually fixate within the population.
The fixation of an allele can occur through different mechanisms. For example, if a beneficial allele provides a selective advantage to individuals carrying it, it is more likely to increase in frequency and eventually become fixed in the population. On the other hand, genetic drift, which is the random change in allele frequencies due to chance events, can also lead to the fixation of an allele, especially in small populations.
Once an allele is fixed in a population, it means that all future generations will inherit that allele, and no alternative alleles will be present at that particular gene locus.

The length of a rectangle is 3 more than twice the width. the perimeter is 36 inches. what is the area?
If the length of a rectangle is 3 more than twice the width and the perimeter is 36 inches, then the area of the rectangle is equal to 65 in².
The length and width of the rectangle can be determined by using the formula for the perimeter of the rectangle,
P = ( L + W ) × 2
P = 2L + 2W
Here L is equal to the length of the rectangle and W is the width of the rectangle.
As the length is 3 more than twice the width, we can write the length of the rectangle as,
L = 3 + 2W
Putting L = 3 + 2W in the equation of perimeter,
P = 2L + 2W
As P = 36
36 = 2( 3 + 2W) + 2W
36 = 6 + 4W + 2W
6W = 30
W = 30 ÷ 6
W = 5
The length of the rectangle can be found by putting W = 5 in the equation,
L = 3 + 2W
L = 3 + 2(5)
L= 3 + 10
L = 13
Therefore, the length and width of the rectangle are equal to 13 and 5 respectively
As, area = width × length
area = 5 × 13
area = 65
Hence, the area of the rectangle is equal to 65 square inches.

What is a histogram?A histogram is a graphical representation of data used to display the distribution of values in a dataset, showing data in bins or intervals along the horizontal axis.
The data distribution in the histogram is uneven or tilted to the right. This suggests that there are fewer students who have gone water skiing less frequently (1 to 5 trips) and more students who have gone water skiing more frequently (11 to 15 trips). The frequency is greatest between 11 and 15 visits, which is reflected by the largest bar in the histogram.
In given problem, the skewed distribution of the given data shows that there are more no. of the students doing water-skiing regularly than those who are doing it less frequently.
This might imply that there is a group of students who are more experienced or enthusiastic about water skiing, and they have gone on more excursions than other students who have gone on less trips.

The high school dropout rate in the United States is greater than 25 percent. C. Wright Mills would classify this situation as a societal issue.
This is because societal issues are matters of public concern that affect large numbers of people and require collective action to resolve. The high school dropout rate in the United States is an example of a societal issue because it has widespread implications for both individuals and society as a whole.
According to Mills, a societal issue is one that cannot be attributed solely to the actions of individuals. Instead, it is the result of social structures and processes that operate at a broader level.
For example, the high school dropout rate in the United States is influenced by a variety of factors such as poverty, race, and family background. These factors are not solely determined by the actions of individual students but are instead shaped by broader social forces such as economic inequality and institutional racism.
To address the high school dropout rate, therefore, requires collective action at the societal level. This may involve policy changes, community-based initiatives, or other forms of collective action aimed at addressing the underlying social factors that contribute to the problem.

Scott is trying to decide which amusement park to go to during vacation.
Amusement park A costs $2.50 per ride with a $40 entry fee. Amusement park B
costs $4.00 per ride with a $30 entry fee. Which inequality can be used to determine
x, the minimum number of rides Scott has to go on so that the total charge at
amusement park A costs less than the total charge at amusement park B?
A. 2.5x + 40<4x +30
B. 2.5x + 40> 4x + 30
C. 2.5+ 40x<4+ 30x
D. 2.5+ 40x>4+30x
The inequality where the total charge for amusement park A costs less than park B is 30 + 4x > 40 + 2.50x.
Option A is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Amusement park A:
Cost per ride = $2.50
Entry fee = $40
Total cost for x rides.
= 40 + 2.50x
Amusement park B:
Cost per ride = $4
Entry fee = $30
Total cost for x rides.
= 30 + 4x
Now,
The inequality where the total charge for amusement park A costs less than park B.
30 + 4x > 40 + 2.50x
Thus,
The inequality is 30 + 4x > 40 + 2.50x.
