SOLUTION
From the question,
Let x represent acres for apple orchard
Let y represent acres for peach orchard
Since the farmer can afford a maximum of 54 acres of land, that means
[tex]x+y\le54[/tex]The apple orchard requires 3000 gallons of water, while the peach requires 800 gallons of water. But the farmers irrigation system can deliver a maximum of 80,000 gallons per day, puting in an equation, we have
[tex]3000x+800y\le80,000[/tex]From his apple orchard, he expects to get a profit of $3,400 per year and from peach, a profit of $1,600 per year.
His expected profit will be determined using the equation
[tex]\begin{gathered} P=3400x+1600y \\ \text{where P is the expected maximum profit } \end{gathered}[/tex]So, we will plot the following points
[tex]\begin{gathered} x+y\le54 \\ 3000x+800y\le80,000 \end{gathered}[/tex]This will help us to get the required region needed to find the expected maximum profit
We can see that this is the same with graph B from the question
Now, we will substitute the following points from the graph into the equation of the maximum expected profit. Which ever that gives us the highest value becomes the answer.
For point (0, 54) we have
[tex]\begin{gathered} P=3400x+1600y \\ P=3400(0)+1600(54) \\ P=0+86,400 \\ P=86,400 \end{gathered}[/tex]For Point (16.727, 37.273), we have
[tex]\begin{gathered} P=3400x+1600y \\ P=3400(16.727)+1600(37.273) \\ P=56,871.8+59,636.8 \\ P=116,508.6 \end{gathered}[/tex]Finally, for point (26.667, 0) we have
[tex]\begin{gathered} P=3400x+1600y \\ P=3400(26.667)+1600(0) \\ P=90,667.8+0 \\ P=90,667.8 \end{gathered}[/tex]We can see that the maximum profit is $116,508.60, from
point (16.727, 37.273)
Hence the division of land that will maximize his expected profit is
16.73 acres of land for apple orchard
37.27 acres of land for peach orchard
Now, looking at the graph, the point (30, 20) lies outside the required region, so the farmer cannot maximize his profit at 30 acres for apple orchard and 20 acres for peach orchard.
Hence the answer is No, because the point (30, 20) lies outside the solution region.

Have a good day!Suppose that you decide to buy a car for $32,635, including taxes and license fees. You saved $9,000 for a down payment and can get a four year car loan at 6.31%. Find the monthly payment and the total interest for the loan. Equation below.
Answers
SOLUTION:
Step 1:
In this question, we are given the following:
Suppose that you decide to buy a car for $32,635, including taxes and license fees.
You saved $9,000 for a down payment and can get a four-year car loan at 6.31%.
Find the monthly payment and the total interest for the loan.
Step 2:
In this question, we are given:
Cost of the car = $ 32, 635
Down payment = $ 9000
Principal on the Car loan = $ ( 32,635 - 9,000 ) = $ 23, 635
Rate = 6. 31%

[tex]\begin{gathered} Initial\text{ }value=1,050 \\ Final\text{ }value=2,050 \end{gathered}[/tex]Therefore, substituting these values into the formula and evaluating, you get:
[tex]\begin{gathered} PercentageIncrease=\frac{2,050-1,050}{|1,050|}\cdot100 \\ \\ PercentageIncrease=95.24 \end{gathered}[/tex]Hence, the answer is: 95.24% increase.

hello
to compare or know the difference between rational numbers and integers
rational numbers are numbers in which are expressed as fractions of two integers eg a/b where b is a non zero number
integers are whole numbers in mathemathics without the expression in fraction or rather they're expressed in fractions but the denominator must be equal to 1
now when we want to compare and order integers, they're prefereably done using the number line system.

Answers
a) the cost of the house is 96000 and the down paidment is the 20% so we can use a rule of 3 to solve it so:
[tex]\begin{gathered} 96000\to100 \\ x\to20 \end{gathered}[/tex]so the equation will be:
[tex]\begin{gathered} x=\frac{96000\cdot20}{100} \\ x=19200 \end{gathered}[/tex]b) her income is $4000 so the 28% will be:
[tex]\begin{gathered} 4000\to100 \\ x\to28 \end{gathered}[/tex]so the equation will be:
[tex]\begin{gathered} x=\frac{4000\cdot28}{100} \\ x=1120 \end{gathered}[/tex]c) the equation that models a loan is:
[tex]C=\frac{P\cdot(0.095\cdot(1+0.095)^n)}{(1+0.095)^{25}-1}[/tex]So we replace the princeiple and find monthly paidment.

Given,
The data set;
1.9, 2.8, 5.7, 4.8, 1.9, 8.6, 3.9, 7.3
a) We have to find the mean, median and mode
Mean = (1.9 + 2.8 + 5.7 + 4.8 + 1.9 + 8.6 + 3.9 + 7.3) / 8 = 36.9/8 = 4.61Median;Order the data first;

The data is of even number, so;
Median = [(n/2) + (n/2 + 1)] / 2
Here,
n/2 = 8/2 = 4th term
n/2 + 1 = 5th term
Then,
Median = (3.9 + 4.8) / 2 = 8.7/2 = 4.35
Mode;The mode of the given data is 1.9

Answers
Given:
a function is given as h(x) = -2x + 9
Find:
we have to evaluate the function at x = -2 , 0 and 5.
Explanation:
when x = -2
h(-2) = -2(-2) + 9 = 4 + 9 = 13
when x = 0
h(0) = -2(0) + 9 = 0 + 9 = 9
when x = 5
h(5) = -2(5) + 9 = - 10 + 9 = -1
Therefore, the values of given function h(x) are 13, 9 , -1 at x = -2, 0 , 5 respectively.

If the measures of the angles of a triangle arerepresented by 2x, 3x - 15, and 7x +15, the triangleis1) an isosceles triangle2) a right triangle3) an acute triangle4) an equiangular triangle
Answers
Answer
Option 1 is correct.
The triangle is an isosceles triangle.
Explanation
Noting that the sum of angles in a triangle is 180°.
We can solve for each of the angles in this triangle to obtain the type of triangle it is.
The angles of the triangle are 2x, (3x - 15) and (7x + 15)
2x + 3x - 15 + 7x + 15 = 180°
2x + 3x + 7x - 15 + 15 = 180°
12x = 180°
Divide both sides by 12
(12x/12) = (180°/12)
x = 15°
We can then solve for the measures of the three angles now
2x = 2 (15°) = 30°
3x - 15 = 3 (15°) - 15° = 45° - 15° = 30°
7x + 15 = 7 (15°) + 15° = 105° + 15° = 120°
So, the angles of the triangle are 30°, 30° and 120°
A tringle that has two of its angles equal to each other is called an isosceles triangle.

16 The water level of a river was measured each day during a two-week period. The graph models the linear relationship between the water level of the river in feet and the number of days the water level was measured. Water Level of River 28 20 16 Water Level (0) 3 4 6 8 10 12 14 Number of Days Which statement best describes the y-intercept of the graph?
Answers
From the graph, it can be observed that line intersect the y-axis at (0,16) and after that level of water increases with increase in number of days.
So 16 feet represents the initial water level of the river. The correct answer is,
The initial water level was 16 ft.
