Answer:
(26,65)
Step-by-step explanation:
We know that each package has 5 sheets of paper and 2 staples. So, to know how many sheets of paper and staples that will be used in 13 packages, we just need to multiply each quantity of material used by 13.
So, we have that:
Total sheets of paper = 13 * 5 = 65
Total staples = 13 * 2 = 26
So the ordered pair (x,y), where x is staples and y is sheets of paper is:
(26,65)
Answer:
The ordered pair is (26, 65).
Step-by-step explanation:
From the given information, a package has 5 sheets of paper and is held together with 2 staples.
13 packets contains 13 packages, so that:
Number of sheet of paper required = 13 × 5
= 65
Number of staples required = 13 × 2
= 26
Therefore, the ordered pair is; staples (26) and sheets of paper (65) i.e (26, 65).

In the diagram line m is parallel to line n with a transversal line t.
Which other angle would be the alternate interior angle to BEF ?
Group of answer choices
DEB
EBC
ABE
CBH
The alternate interior angle to ∠BEF is ∠DEB, which is on the opposite side of the transversal line t and lies between the parallel lines m and n.
Explanation:In the context of geometry and specifically the study of parallel lines and transversals, alternate interior angles are pairs of angles on opposite sides of the transversal but inside the two lines.
Since line m is parallel to line n with transversal line t, the alternate interior angle to ∠BEF should also be on the opposite side of the transversal and inside the parallel lines, but not adjacent to ∠BEF. Considering the choices presented and assuming the standard notation for angles in geometric figures, ∠DEB would be the alternate interior angle to ∠BEF since it is non-adjacent and lies between line m and line n on the opposite side of the transversal.

Which scatterplot shows the strongest relationship between the variable x and the variable y
The scatterplot that shows the strongest relationship is, a graph has x on the x-axis, and y on the y-axis. Points increase loosely together.
What is Correlation coefficient of scatterplot?The correlation coefficient of scatterplot is used to demonstrate the relationship between variables.
When two variables increases together, they are said to have positive correlation.
Similary when one is increasing and another is decreasing, they are said to have negative correlation.
From the given options;
We can see that Option A, zero correlation
Option B, less than 1
Option C, 1 or greater than 1
Option D, -1 or less than 1

Final answer:
A scatterplot that shows a strong relationship between variables x and y will have points tightly clustered around the regression line, indicating x has a strong influence on y. It is a key visual tool to assess the potential for linear regression, but caution is needed as it does not prove causation and outliers or non-linear trends can influence interpretations.
Explanation:
Understanding Scatterplot Relationships
When determining the strength of a relationship between variable x and variable y on a scatterplot, one looks for how closely the data points follow a particular trend or pattern. A scatterplot with a strong relationship between the variables will show that the points are tightly clustered around a line, known as the regression line, which passes through the mean of the data set. This clustering signifies that x has a strong influence on y.
However, it's important to note that a strong relationship does not confirm causation. For a scatterplot to represent a good candidate for linear regression, the pattern of points should not only be tight but also linear. If the data shows an obvious non-linear relationship, or if there are outliers that significantly affect the correlation coefficient, one should be cautious in interpreting the results. The decision to use linear regression is best made after a visual inspection of the scatterplot and consideration of the relationship's linearity.
To visualize a correlation and assess the potential influence one variable may have on another, a researcher can use a scatterplot. This graph plots points at the intersection of the paired values on Cartesian coordinates, providing a clear image of the relationship.

What two numbers multiply to -4 and add to 3
4 * -1 = -4
4+-1 = 3
( x+4) ( x-1)
The factors of x^2 + 3x - 4 are (x + 4) and (x - 1). To find the factors, identify two numbers that multiply to -4 and add up to 3. The factored form of x^2 + 3x - 4 is (x + 4)(x - 1).
The factors of x2 + 3x - 4 are (x + 4) and (x - 1).
To find the factors, you need to look for two numbers that multiply to -4 and add up to 3 (the coefficient of the x-term).
Therefore, x2 + 3x - 4 = (x + 4)(x - 1).

To find:
Volume of the rectangular prism.
Solution:
Surface area formula:
[tex]SA = 2(lw+wh+lh)[/tex]
Substitute the given values.
[tex]4362 = 2(36\times21 +21 \times c+36 \times c)[/tex]
[tex]4362 = 2(756+21 c+36 c)[/tex]
[tex]4362 = 2(756+57c)[/tex]
[tex]4362 = 1512+114c[/tex]
Subtract 1512 from both sides.
[tex]4362- 1512 = 1512+114c - 1512[/tex]
[tex]2850=114c[/tex]
Divide by 114 on both sides, we get
25 = c
Height = 25
Volume = length × breadth × height
= 36 × 21 × 25
= 18900
Volume of rectangular prism is 18900 cubic yards.

Diamonds have a density of 3.5 LaTeX: \frac{g}{cm^3}g c m 3. How big is a diamond that has a mass of 0.10 g?
For this case we have that by definition, the density is given by:
[tex]d = \frac {M} {V}[/tex]
Where:
M: It is the mass of the diamond
V: It is the volume of the diamond
According to the data of the statement we have:
[tex]d = 3.5 \frac {g} {cm ^ 3}\\M = 0.10 \ g[/tex]
So the volume is:
[tex]V = \frac {M} {d}\\V = \frac {0.10 \ g} {3.5 \frac {g} {cm ^ 3}}\\V = 0.02857\\V = 0.03 \ cm^3[/tex]
Thus, the volume of the diamond is approximately [tex]0.03 \ cm ^ 3[/tex]

425 / 3333 is it a rational number
The answer is yes, 425 divided by 3333 is a rational number.
A rational number is defined as any number that can be expressed as the quotient or fraction p/q of two integers, where the numerator p is an integer, and the denominator q is a non-zero integer. In this case, 425 is an integer, and 3333 is a non-zero integer. Therefore, the fraction 425/3333 is indeed a rational number.
To demonstrate this, we can perform the division:
[tex]\[ \frac{425}{3333} \approx 0.1275 \][/tex]
This decimal representation is a repeating decimal, which is another characteristic of rational numbers. Rational numbers either terminate after a finite number of digits or begin to repeat the same finite sequence of digits over and over. The decimal expansion of 425/3333 is a repeating decimal; hence, it satisfies the definition of a rational number.
Part A: A triangle has angles measuring 2xo, xo, and 45o. Write an equation that can be solved to find the value of x?
Part B: Using your equation from part A, Find the measure of each angle, in degrees.
Angle 2x*__________; Angle x*__________
Answer:
X° + 2x° + 45° = 180°
X = 45°, 2x = 90°
Step-by-step explanation:
Since the angles in a triangle sums up to 180
And the angles in this particular triangle is measured as 2x° + x° + 45° = 180
With this equation, we can find the value of x and 2x
2x + x + 45 = 180
3x + 45 = 180
3x = 180 - 45
3x = 135
Now divide both sides by 3
3x/3 = 135/3
X = 45
Therefore, the angles of that triangle are x° = 45, 2x°= 45 × 2 = 90° and the third angle which was given to us as 45°

An oval track is made by erecting semicircles on each end of a 46 m by 92 m rectangle. Find the length of the track and
the area enclosed by the track.
Answer:
[tex]Length\,\, of\,\, the\,\, track=420.44\,m\\\\Area\,\,covered \,\,by\,\, the\,\, track=5893.06\,m^2[/tex]
Step-by-step explanation:
Length of the Track:
Perimeter of the rectangle + Circumference of the two semicircle
Perimeter of the rectangle= [tex]2(Length+Width)[/tex]
[tex]Length=92\,m\\Width=46\,m[/tex]
Perimeter of the rectangle:
[tex]=2(92+46)\\\\=2(138)\\\\=276\,m[/tex]
Circumference of Two Semicircle with same radius:
[tex]r=\dfrac{46}{2} =23\,m[/tex]
[tex]Circumference=2\times \pi \times r\\\\[/tex]
[tex]=2\times 3.14\times 23\\\\=6.28 \times 23\\\\=144.44\,m[/tex]
Total Length of the track is :
[tex]=276+144.44\\\\=420.44\,m[/tex]
Area Covered by the track is :
Area of the two semicircle + Area of the rectangle
[tex]=(\pi \times r^2) + (Length\times Width)\\\\=(3.14\times (23\times 23 ))+(92\times 46)\\\\=1661.06 +4232\\\\=5893.06\,m^2[/tex]
The total length of the oval track is 420.51m and the area enclosed by the track is 5893.90m².
Explanation:The dimensions of the rectangular part of the track are 46m and 92m respectively. Thus, the total distance around the rectangle (perimeter) is 2*(46m + 92m) = 276m. The two semicircles on either end of the rectangle form a complete circle with a diameter of 46m. The circumference of this circle (which equates to the remaining path length of the race track) is given by the formula πd or π*46m ≈ 144.51m. Thus, the total length of the track is 276m + 144.51m = 420.51m.
As for the area enclosed by the track, it consists of two main parts: the area of the rectangle and the area of the circle. The area of the rectangle is given by the formula L*W, or 46m*92m = 4232m². The area of the circle is given by the formula π(r²), where r is the radius of the circle. So, π(23m²) equals approximately 1661.90m². Adding the two results together, the total area enclosed by the track is 4232m² + 1661.90m² = 5893.90m².

Distance between any two coordinates can be measured by a number of grids between them if they are colinear but if they are not we need to find the inclined distance.
Since A and C are 4 grids up and down but C is not co-linear with A so distance will be more than 4.
Coordinate B and D are colinear and has four grid distance so it will be the answer.
Hence "Points B and D are 4 units apart in the given coordinate plane".
