The statement that proves that parallelogram KLMN is a rhombus is. The slope of KM is 1 and the slope of NL is –1.
What is a Rhombus?
This is a type of quadrilateral that has four sides of which they are all equal.
Hence, given that KLMN is a parallelogram, K(7,7), L(5,3), M(1,1) and N(3,5).
We know that they bisect each other and if the diagonals of a parallelogram are perpendicular to each other then the parallelogram is a rhombus.
Therefore, The slope of KM is 1 and the slope of NL is –1.

Find the volume of this compound figure.
Hint: Half a sphere and a cylinder
Use 3.14 for pi!
The volume of the given shape will be equal to V=2827.42 cubic inches.
What is volume?The volume is defined as the space occupied by the object in the three-dimensional plane. It requires three coordinates to find the volume of any object.
Here it is given in the question that:-
Radius of the semicircle=12 inches
Height of the cylinder =13 inches.
Now the volume will be calculated as:-
Total volume of the figure will be the sum of the Volume of the semicircle and the Volume of the cylinder.
= 2πr³+πr²l
= 2xπx(6)³+πx(6)²x13
=1357.16+1470.26
=2827.42 Cubic inches
Hence the volume of the given shape will be equal to V=2827.42 cubic inches.

What is the slope of the line through the points (-2, -1) and (4, 3)?
Ans: 2/3
Step-by-step explanation:
Formula : [tex]m = \frac{y2 - y1}{x2- x1}[/tex] (Then replace the number in )
= 3- (-1) / 4 - (-2) = 4 / 6 = 2 / 3
Step-by-step explanation:
the slope is always the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, when going from (-2, -1) to (4, 3)
x changes by +6 (from -2 to 4).
y changes by +4 (from -1 to 3).
therefore, the slope is
+4/+6 = 4/6 = 2/3

Two companies offer river tubing trips.
• The first company charges $7.50 rental fee for the tube and $3.00 an hour.
• The second company charges $10.50 rental fee for the tube and $2.00 an hour.
What is the minimum number of hours a person would need to rent a tube in order for
the second company to be a better deal?
Minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.
What is a mathematical model?A mathematical model is the model which is used to explain any system, the effect of the components by study and estimate the functions of systems.
Two companies (first and second) offers river tubing trips and the rates of them are as follows: The first company charges $7.50 rental fee for one tube, with a charge of $3.00 an hour.
For the x hours, the charge of the company is,
7.50+3.00x
The second company charges $10.50 rental fee for one tube with a charge of $2.00 an hour. For the x hours, the charge of the company is,
10.50+2.00x
Let x is the hour at which the cost of both companies are equal. Thus,
7.50+3.00x=10.50+2.00x
3x-2x=10.5-7.5
x=2.5
Thus, the minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.

To determine whether students

surveys every 25th student from an
alphabetized list of students in the
school. Will the survey results from
this sample support a valid inference?
Explain.
Using sampling concepts, it is found that the sample would not support a valid inference, as both alphabetized and non-alphabetized students should be sampled.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
The school has both alphabetized and non-alphabetized students, and both groups should be sampled for a valid inference to be made. Since only alphabetized students are sampled, the sample would not support a valid inference.

Answer:
1.59 ft.. sort of
Step-by-step explanation:
4th and final attempt:
10 * 5 + 2(10x + 2x) + 2(5x) = 104
50 + 2(12x) + 10x = 104
50 + 24x + 10x = 104
50 + 34x = 104
34x = 104 - 50
34x = 54
x = 54 / 34
x ~= 1.59

On a coordinate plane, a line is drawn from point a to point b. point a is at (9, negative 8) and point b is at (negative 6, 7). what are the x- and y- coordinates of point p on the directed line segment from a to b such that p is two-thirds the length of the line segment from a to b? x = (startfraction m over m n endfraction) (x 2 minus x 1) x 1 y = (startfraction m over m n endfraction) (y 2 minus y 1) y 1 (2, –1) (4, –3) (–1, 2) (3, –2)
Using proportions, it is found that the coordinates of p in the line segment are given as follows: (-1,2).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the points are:
Point a(9, -8).Point b(-6, 7).Point p(x, y).p is two-thirds the length of the line segment from a to b, hence:
[tex]p - a = \frac{2}{3}(b - a)[/tex]
For the x-coordinate, we have that:
[tex]x - 9 = \frac{2}{3}(-6 - 9)[/tex]
x - 9 = -10
x = -1
For the y-coordinate, we have that:
[tex]y + 8 = \frac{2}{3}(7 - (-8))[/tex]
y + 8 = 10
y = 2.
The coordinates of p are (-1,2).

1½ miles/day .
Step-by-step explanation:
To find:-
The rate at which the construction crew built thr road.Answer:-
It is given that the crew made 8¼ miles of road in 5½ days . To find the rate of work done , simply divide the total length of road nade by total time taken . That would be , ( rate is represented by "r" . )
[tex]:\implies \sf r = 8\dfrac{1}{4}\div 5\dfrac{1}{2} \ miles/day\\[/tex]
Convert the mixed fraction into improper fraction.
[tex]:\implies \sf r = \dfrac{33}{4}\div \dfrac{11}{2} \ miles/day \\[/tex]
For dividing them , multiply the reciprocal of 11/2 by 33/4 as ,
[tex]:\implies \sf r = \dfrac{33}{4}\times \dfrac{2}{11} \ miles/day\\[/tex]
[tex]:\implies \sf r = \dfrac{3}{2} \ miles/day \\[/tex]
[tex]:\implies \sf \pink{ r = 1\dfrac{1}{2}\ miles/day } \\[/tex]
Hence the unit rate of constructing the road is 1½ miles/day .

The price went down by 15%, and went 340 money. What was the previous price? ASAPP PLSS
The previous price given the percentage decrease is 400.
How to find the previous price?It follows from the task content that the previous price of the commodity is required;
let, x = previous price
New price = 340
Percentage decrease = 15%
Hence, it follows from the given information that;
340 = x - (15% × x)
340 = x - (0.15x)
340 = 0.85x
x = 340/0.85
x = 400
Therefore, the previous price given the percentage decrease is 400.
