A parcel occupies the nw 1/4 of the se 1/4, and the s 1/2 of the sw 1/4 of the ne 1/4. How many acres is this parcel?
Answers
The parcel is 30 acres in size, calculated as 10 acres for the NW 1/4 of the SE 1/4 and 20 acres for the S 1/2 of the SW 1/4 of the NE 1/4.
To solve the problem, we need to know the size of the quarter sections that are being referred to. In the United States, a quarter section is 160 acres.
Using this information, we can break down the given parcel as follows:
NW 1/4 of the SE 1/4: This represents 1/16 of a section, or 10 acres (160 acres / 16 * 1 = 10).
S 1/2 of the SW 1/4 of the NE 1/4: This represents 1/8 of a section, or 20 acres (160 acres / 8 * 1/2 = 20).
To find the total size of the parcel, we simply add these two areas together:
(10 + 20 )acres = 30 acres
Therefore, the parcel is 30 acres in size.
In the United States, a section of land is a unit of area measurement used in land surveys, and it is equal to 640 acres. A quarter section is, therefore, one-fourth of a section, or 160 acres.
The given parcel is described as two parts. The first part is the northwest quarter of the southeast quarter, which is equivalent to one-sixteenth of a section or 10 acres (1/4 x 1/4 x 160 acres = 10 acres).
The second part is the south half of the southwest quarter of the northeast quarter, which is equivalent to one-eighth of a section or 20 acres (1/4 x 1/4 x 1/2 x 160 acres = 20 acres).
To find the total size of the parcel, we add the area of the two parts: 10 acres + 20 acres = 30 acres. Therefore, the parcel is 30 acres in size.

Sophia brought some almonds from the store. She handed the cashier $15 and received $5 in change. Mr. Boone is buying an app for the class. The app costs a dollars per student and he has 32 students. He spends $96. How much is the app per student?
Answers
The cost per student for the app is $3, and can be found by dividing the total cost of $96 by the number of students, 32, which equals $3 per student.
Let x be the cost of the almonds Sophia bought and y be the cost of the app per student. Then, we have the subsequent two equations:
x + $5 = $15
32y = $96
To find the cost of the app per student, we can solve for y in the second equation:
y = $96 / 32 = $3
So the app costs $3 per student.
To find the cost of the app per student, we need to find the total cost of the app and then divide it by the number of students. Mr. Boone spent $96 on the app for 32 students, so the cost per student would be $96 / 32 = $3. This means that each student paid $3 for the app.

Answers
The soy candles cost $12.83 each and the specialty candles cost $10.72 each then the Asunta's Candle Store ordered 293 soy candles and 457 specialty candles.
What is system of linear equations?
Let's use the following variables:
Let x be the number of soy candlesLet y be the number of specialty candlesWe have two equations based on the information given in the problem:
x + y = 750 (the total number of candles ordered)12.83x + 10.72y = 8660.34 (the total wholesale cost of the candles)To solve for x and y, we can use a system of linear equations. One way to do this is to solve for one variable in one equation, and substitute that expression into the other equation. For example, we can solve for x in the first equation:
x + y = 750
x = 750 - y
Then we substitute this expression for x in the second equation:
12.83x + 10.72y = 8660.34
12.83(750 - y) + 10.72y = 8660.34
Simplifying and solving for y:
9622.5 - 2.11y = 8660.34
-2.11y = -962.16
y = 456.5
We can then substitute this value for y in the first equation to find x:
x + y = 750
x + 456.5 = 750
x = 293.5
Therefore, Asunta's Candle Store ordered 293 soy candles and 457 specialty candles.

How to evaluate for angle m∠B of the quadrilateralThe complete question is added as an attachment
For any quadrilateral, the sum of its four interior angles is equal to 360°,
Using the above as a guide, we have the following:
17x + 5 + 13x + 7 + 118° + 80° = 360°
Evaluate the like terms
So, we have
30x + 210° = 360°
Subtract 210° from both sides
30x = 150°
So, we have
x = 5
Given that
B = 13x + 7
We have
B = 13 * 5 + 7
Evaluate
B = 72

Answers
The trees will be the same height in 2 years and the height of these trees will be 22 ft.
Linear Expression
A linear expression can be represented by a line. The standard form for this equation is: y=mx+b , for example, y=x+10. Where:
m= the slope.
b= the constant term that represents the y-intercept
For the given example: m=1 and b=10.
For solving the question you should convert the given text into an algebraic expression.
Tree01= 18+2*y
Tree02= 20.5+0.75*y (Note that 3/4=0.75)
y= number of years
Therefore,
18+2*y=20.5+0.75*y
2y-0.75*y=20.5-18
1.25y=2,5
y=2
Thus, at 2 years the trees will be the same height.
When y=2, you have:
Tree01= 18+2*y= 18+2*2=18+4=22

What is the standard deviation of the data set {2,1,1,2,2,3}?
You may use the desmos calculator to assist you.
Enter your answer as a number, rounded to the nearest tenth
Answers
The standard deviation of the data set is 0.7.
How to calculate standard deviation?First, calculate the mean of the data set:
(mean) = (2+1+1+2+2+3)/6 = 11/6 ≈ 1.8
Next, calculate the deviation of each data point from the mean:
2 - 1.8 = 0.2
1 - 1.8 = -0.8
1 - 1.8 = -0.8
2 - 1.8 = 0.2
2 - 1.8 = 0.2
3 - 1.8 = 1.2
Now square each deviation:
0.2² = 0.04
(-0.8)² = 0.64
(-0.8)² = 0.64
0.2² = 0.04
0.2² = 0.04
1.2² = 1.44
The sum of the squared deviations is:
0.04 + 0.64 + 0.64 + 0.04 + 0.04 + 1.44 = 2.84
To find the variance, we divide by the number of data points:
variance = 2.84/6 ≈ 0.4733
Finally, take the square root of the variance to get the standard deviation:
standard deviation = √(0.4733) ≈ 0.69
Therefore, the standard deviation of the data set {2,1,1,2,2,3} is approximately 0.7 (rounded to the nearest tenth).

Answers
There are 180 different starting lineups that can be created for the college team.To find the number of different starting lineups that can be created for the college team, we need to use the combination formula.
The number of ways to choose k items from a set of n distinct items is given by the formula:
nCk = n! / (k! * (n-k)!)
where "!" denotes the factorial function, which means the product of all positive integers up to that number.
In this case, we want to choose 2 guards out of 5, 2 forwards out of 4, and 1 center out of 3. So the total number of different starting lineups that can be created is:
(5C2) * (4C2) * (3C1)
= (5! / (2! * 3!)) * (4! / (2! * 2!)) * (3! / (1! * 2!))

A person is measuring for new carpet in an auditorium. the angle of elevation from the front to back is 12 degrees and the last row is 15 feet higher than the front row. what is the straight line distance from the front seat to the back? round to the nearest tenth
Answers
The straight line distance from the front seat to the back is approximately 69.7 feet.
What is a straight line distance?Straight line distance refers to the shortest distance between two points in a straight line, as opposed to the distance that would be traveled along a curved path or following the contours of the terrain.
Let the distance from the front row to the back row be x.
Then, we can use the tangent function to find the height difference between the front and back rows:
tan(12°) = (height difference) / x
Solving for the height difference:
height difference = x * tan(12°)
The problem tells us that the height difference is 15 feet, so we can set up an equation:
15 = x * tan(12°)
Solving for x:
x = 15 / tan(12°) ≈ 69.7 feet
Therefore, the straight line distance from the front seat to the back is approximately 69.7 feet.
