In linear equation , 2,932.25 * ( 1.0316)¹²t = (1)t is value of t .
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an uncertain variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.275000 = 3001 - ( 1 + 0.38/12)⁻¹²t/0.038/12
275000 = 3001 - ( 1 + 0.38/12)⁻¹²t/0.0025
275000 * 0.0025 = 3001 - ( 1 + 0.38/12)⁻¹²t
68.75 = 3001 - ( 1 + 0.38/12)⁻¹²t
3001 - 68.75 = ( 1 + 0.38/12)⁻¹²t
2,932.25 = ( 1 + 0.0316)⁻¹²t

Rafael is fertilizing his garden. The garden is in the shape of a rectangle. Its length is 16 feet and its width is 13 feet. Suppose each bag of fertilizer covers 26 square feet. How many bags will he need to cover the garden?
step 1
Find the area of the garden
Remember that the area of a rectangle is equal to
A=L*W
we have
L=16 ft
W=13 ft
substitute
A=16*13
A=208 ft^2
step 2
we know that
each bag of fertilizer covers 26 square feet
so
Applying proportion
1/26=x/208
solve for x
x ----> number of bags
x=(1/26)*208
x=8 bags
therefore
the answer is 8 bagsTranslate this sentence into an equation.

If the dining hall is located at (-12,6) and the stables are located at (20,6), then the dining hall is 32 units apart from the stables
The location of the dining hall = (-12,6)
The location of the stables = (20,6)
The distance between the two points d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Where d is the distance between the two points
[tex](x_1,y_1)[/tex] is the coordinates of the first point
[tex](x_2,y_2)[/tex] is the coordinates of the second point
Substitute the values in the equation
d = [tex]\sqrt{20-(12))^2+(6-6)^2}[/tex]
= [tex]\sqrt{1024}[/tex]
= 32 units
Hence, if the dining hall is located at (-12,6) and the stables are located at (20,6), then the dining hall is 32 units apart from the stables

x^2-y=7 and y-5x=-11 The system of equations above has two solutions. The solution in Quadrant 1 is (A,B) and the solution in Quadrant 4 is (C,D) . Find the values of (A,B), (C,D)
By solving the system of equations, we can see that the solutions are:
(A, B) = (4, 9)
(C, D) = (1, -6).
How to solve the system of equations?Here we have the following system of equations:
x^2 - y = 7
y - 5x = -11
If we isolate the variable y in both equations, we get:
y = x^2 - 7
y = -11 + 5x
Now we can equate these two to get:
x^2 - 7 = -11 + 5x
now we have a quadratic equation, this can be rewritten as:
x^2 - 7 + 11 - 5x = 0
x^2 - 5x + 4 = 0
Using the quadratic formula, we will see that the solutions are:
[tex]x = \frac{5 \pm \sqrt{(-5)^2 - 4*1*(4)} }{2*1}[/tex]
Solving that we get:
[tex]x = \frac{5 \pm \sqrt{(9} }{2} \\\\x = \frac{5 \pm 3}{2}[/tex]
So the two solutions for x are:
x = (5 + 3)/2 = 4
x = (5 - 3)/2 = 1
Evaluating the second equation in these x-values we get:
y = -11 + 5*4 = -11 + 20 = 9
y = -11 + 5*1 = -6
Then we have the coordinate pairs: (4, 9) (on the first quadrant) and (1, -6) on the fourth quadrant.

The value of the Constant of Proportionality will be $2.19.
In the given question, it is stated that 3 pounds of grapes cost $6.57. We have to calculate and find out the Constant of Proportionality.
The constant of Proportionality is a constant term in the equation that does not vary and has a fixed value that represents a certain quantity in a given situation.
Here, we know that 3pounds cost $6.57. Taking:
y = Total Cost
x = Number of Pounds
c = Constant of Proportionality
We get the equation to represent the Total cost with respect to the number of pounds where c will be the proportionality constant which defines the unit price of a pound. The equation will be:
=> y = c*x
=> 6.57 = 3c
=> c = 2.19

Kelyse's preschool tuition is $180 per week. She
receives a small discount for honor roll, $50 per
month. Her grandparents help out and pays
20% of her tuition. How much do her
grandparents pay?
$134 is the amount paid by grandparents every month.
What is the percentage?Percentage as the name suggests is a ratio of some particles to 100. In order to get the value of the required amount one has to divide the value by 100.
It is given that the tuition fee is $180 per week = $720 per month
It is also provided that she receives an honour rule of $50 per month.
So, her fees per month is $720- $50= $670.
It is given that 20% of the fees is paid by grandparents.
So, percentage share = 20% of $670 =20/100 x $ 670 = $134
So, $134 is paid by the grandparents every month.

Based on the reflexive property of congruency, the other pair of sides that we know are congruent is: 1. QS = SQ.
What is the Reflexive Property of Congruency?The reflexive property of congruency states that a line will always be a congruent to itself. This means it will always be equal in measure to itself.
In the diagram given showing triangle QSP and triangle SQR, we are given that sides PQ and RS are congruent so also are angles PQS and RSQ.

4. tumbleweed, commonly found in the western united states, is the dried structure of certain plants that are blown by the wind. kochia, a type of plant that turns into tumbleweed at the end of the summer, is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. scientists are concerned that kochia plants are becoming resistant to the most commonly used herbicide, glyphosate. the us department of the interior claims that 20 percent of kochia plants are resistant to glyphosate. in 2017 another study by researchers at university of new mexico, 38.5 percent of 52 randomly selected kochia plants were resistant to glyphosate.
Using the z-distribution, as we are working with a proportion, it is found that since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.
What are the hypothesis tested?In null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.
In this problem, we consider that:
p₁ is the proportion in 2014.
p₂ is the proportion is 2017.
H₀=p₂-p₁
By alternative hypothesis,
H₁=p₂-p₁≠0,
we test if there has been an increase
The proportions and standard errors are given by:
p₁=0.97, s₁=√0.97(0.803)/61=0.0509
p₂=0.385, s₁=√0.385(0.615)/52=0.0675
Hence, the distribution has mean and standard error given by:
p=p₂-p₁=0.0675-0.0509
s=√s₁²+s₂²=0.0845
Test static z=p bar-p/s
at p = 0 is the value tested at the null hypothesis,
z=0.0166/0.0845
z=0.2
By a right-tailed test, we are testing is the proportion is greater than a value, with a significance level of 0.05, the critical value is of
z=1.645
0.2<1.645 there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

Aryon has $20. He buys 2 cokes that each cost $1.50. He also buys a sandwich for $5.50. And a bag of chips that cost $2.25. After Aryon pays for his lunch, how much money does he have left.
Aryon is left with $9.25 of money after he has paid for his lunch.
According to the question,
We have the following details:
Total amount Aryon has = $20
The cost of 1 coke = $1.50
So, the cost of 2 cokes = $(2*1.50)
The cost of 2 cokes = $3
The cost of a sandwich = $5.50
The cost of a bag of chips = $2.25
So, the total cost of all the materials = the cost of 2 cokes + the cost of a sandwich + the cost of a bag of chips
The total cost of all materials = $(3+5.50+2.25)
The total cost of all materials = $10.75
Now, the money Aryon has = Total money he has - the total cost of all materials
The money Aryon is left with = $(20-10.75)
The money Aryon is left with = $9.25
Hence, the money Aryon is left with is $9.25.

How to calculate the area of the rectangle?
In mathematics, the rectangle is a closed polygon shape which has four vertex as well as four sides. And the opposite side are parallel to each other. To calculate the area, multiply the length and breadth. Similarly, for the perimeter means add all the sides.
According to the question, the given data in the form of the area of the rectangle is as follows:
Area of Rectangle1 = 60.81 square centimeters
Area of Rectangle2 = 61.44 square centimeters
Area of Rectangle3 = 35.52 square centimeters
Area of Rectangle4 = 47.88 square centimeters
Now, to calculate the greatest difference in the area of the rectangles:
Difference(Rect2 - Rect1) = 61.44 - 60.81 = 0.63
Difference(Rect1 - Rect3) = 60.81 - 35.52 = 25.29
