Option B
-0.249851765 is a irrational number
Solution:
Given number is -0.249851765
We have to classify the number
Let us first understand about irrational, real, whole, integer and rational numbers
Integers:An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043
Every integer can be expressed as a decimal, but most numbers that can be expressed as a decimal are not integers. If all the digits after the decimal point are zeroes, the number is an integer. If there are any non-zero digits after the decimal point, the number is not an integer.
Thus -0.249851765 has non zero digits after decimal point. So it is not a integer
Whole numbers:Whole numbers are positive numbers, including zero, without any decimal or fractional parts. Negative numbers are not considered "whole numbers."
But the given number -0.249851765 is negative number. So it is not a whole number
Natural numbers:A natural number is an integer greater than 0. Natural numbers begin at 1 and increment to infinity: 1, 2, 3, 4, 5, etc. Natural numbers are also called "counting numbers" because they are used for counting.
A decimal is a natural number if it is non-negative and the only digits after its decimal points are zero
So the given number -0.249851765 is a negative number and so it is not a natural number
Rational numbers:A rational number is a number that can be expressed as a fraction (ratio) in the form [tex]\frac{p}{q}[/tex] where p and q are integers and q is not zero.
The rational numbers includes all positive numbers, negative numbers and zero that can be written as a ratio (fraction) of one number over another.
When a rational number fraction is divided to form a decimal value, it becomes a terminating or repeating decimal.
So -0.249851765 is not a rational number
Irrational number:An irrational number is real number that cannot be expressed as a ratio of two integers.
When an irrational number is expressed in decimal form, it goes on forever without repeating
So the given number -0.249851765 is irrational number
We can conclude that:
-0.249851765 is a irrational number, So Option B is correct
749/d ∙ d/749=1
what does D equal?
Final answer:
To find the value of d in the equation 749/d ∙ d/749 = 1, we can simplify the equation and solve for d. Canceling out the like terms and cross multiplying leads us to the solution: d = 1.
Explanation:
To find the value of d in the equation 749/d ∙ d/749 = 1, we need to simplify the equation and solve for d.
We can start by canceling out the like terms: 749 and d. Multiplying the numerators and denominators gives us:
(749/d) ∙ (d/749) = (749 ∙ d) / (d ∙ 749)
Since the two fractions are equal to 1, we can set up the equation:
(749 ∙ d) / (d ∙ 749) = 1
Next, we can cross multiply:
749 ∙ d = d ∙ 749
Now, we can divide both sides of the equation by 749:
d = d ∙ 749 / 749
Simplifying further:
d = 749 / 749
Finally, we arrive at the solution:
d = 1

Answer:
The diagonals ZX and YW are perpendicular to each other.
Step-by-step explanation:
We have to prove diagonal ZX is perpendicular to diagonal YW.
Now, the coordinates of Z(0,b), and X(2a,b)
Hence, slope of ZX is m = [tex]\frac{b - b}{2a - 0} = 0[/tex]
Therefore, ZX is parallel to x-axis.
Now, the coordinates of Y(a,0) and W(a,4b)
Hence, slope of YW is n = [tex]\frac{4b - 0}{a - a} = \infty[/tex]
Therefore, YW is parallel to y-axis.
Hence, the diagonals ZX and YW are perpendicular to each other. (Proved)

Answer:
14
Step-by-step explanation:
To subtract 3x2 + 4x – 5 from 7x2 + x + 9, we will take the difference of the two polynomials to have;
7x2 + x + 9 -(3x2 + 4x – 5)
= 7x²+x+9-3x²-4x+5
= 7x²-3x²+x-4x+9+5
= 4x²-3x+14
Further subtracting 4x²-3x from the resulting polynomial will give us;
4x²-3x+14 - (4x²-3x)
= 4x²-3x+14-4x²+3x
= 4x²-4x²-3x+3x+14
= 14
Therefore the final answer is 14
Subtracting 3x^2 + 4x - 5 from 7x^2 + x + 9 yields the polynomial 4x^2 - 3x + 14. The difference polynomial is 4x^2 - 3x + 14.
When subtracting 3x^2 + 4x - 5 from 7x^2 + x + 9, you need to subtract the coefficients of like terms.
Starting with 7x^2 + x + 9 - (3x^2 + 4x - 5), you subtract the corresponding coefficients:
(7x^2 - 3x^2) + (x - 4x) + (9 + 5)
This simplifies to:
4x^2 - 3x + 14
So, the resulting polynomial is 4x^2 - 3x + 14 after subtracting.
In this polynomial, the highest degree term is 4x^2, the linear term is -3x, and the constant term is 14. The difference is a quadratic polynomial with a leading coefficient of 4, a linear term with a coefficient of -3, and a constant term of 14.
This polynomial represents the result of subtracting 3x^2 + 4x - 5 from 7x^2 + x + 9.

Answer:
A. 3 cm
Step-by-step explanation:
The smallest face has the sides 4 cm and 8 cm. If the water is 4 cm from its top, then the height of the water is [tex]16-4=12[/tex] cm and the volume of the water is
[tex]V_{water}=4\cdot 8\cdot 12=384\ cm^3[/tex]
The largest face has the sides 8 cm and 16 cm. If the container is placed on its largest face, then the volume of the water is
[tex]V_{water}=8\cdot 16\cdot h \ cm^3,[/tex]
where h is the height of the water.
Equate volumes of the water:
[tex]8\cdot 16\cdot h=384\\ \\h=\dfrac{384}{8\cdot 16}=3\ cm[/tex]
Therefore, the water is 3 cm from the bottom.
Make a conjecture about two different non vertical lines in the same plane that have the same slope
Two different non-vertical lines in the same plane with the same slope are parallel to each other. The slope determines the angle of the line with respect to the x-axis, and lines with the same slope do not intersect if they have different y-intercepts.
Explanation:When making a conjecture about two different non-vertical lines in the same plane that have the same slope, one can conclude that these two lines are parallel to each other. This is because the slope of a line represents the steepness and direction of the line, and lines with the same slope will never intersect and are hence parallel. The slope is determined by the ratio of the rise (change in y) over the run (change in x), and as illustrated in Figure A1, the slope is consistent along the entire length of a straight line. If two lines have the same slope but different y-intercepts, they will maintain the same angle with respect to the x-axis but will be positioned at different locations in the plane.
An example is given in Figure A1, where a line has a y-intercept of 9 and a slope of 3. The slope and y-intercept are represented by the 'm' and 'b' terms in the linear equation y = mx + b. Therefore, even if two lines have the same 'm' value, if their 'b' values are different, the lines will be parallel but not coincident (overlapping).

Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.
Step-by-step explanation:
The connection can be described by starting with the fundamental concept,procedure or strategy that give rise to the others. In this case, to form a line, you need to have points that join to extend infinitely in different directions. This means the point, is the fundamental concept, that will give the line.A plane is an infinite set of points that form a connected flat surface extending infinitely far in all direction. So here again, the plane exist where there is a set of points. However, a plane is named by three points that are in the plane but not in the same line. Hence, before naming a plane, the concept of a line should be considered. Ranking the three from best to worst will be: point, line, plane.

Answer:
see the explanation
Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to
[tex]y=mx+b[/tex]
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
[tex]y=25x+50[/tex]
This is the equation of a line in slope intercept form
so
Is a linear equation (the graph is a line)
The slope is positive and is equal to [tex]m=25[/tex]
The y-intercept is the point (0,50) (y-intercept is the value of y when the value of x is equal to zero)
The value of b is [tex]b=50[/tex] (y-coordinate of the y-intercept)
The x-intercept is the point (-2,0) (x-intercept is the value of x when the value of y is equal to zero)
The linear function is a increasing function (the slope is positive)

Between 4:00 p.m. and 7:00 p.m. the temperature in Boxerville dropped 18
degrees. If the temperature at 7:00p.m. is 64 degrees, what was the
temperature in degrees at 4:00 p.m.?
Answer here
SUBMIT
To find the temperature in Boxerville at 4:00 p.m. after a drop of 18 degrees by 7:00 p.m. (with a 7:00 p.m. temperature of 64 degrees), we add the dropped degrees back to find the original temperature was 82 degrees.
The question asks to find the temperature at 4:00 p.m. in Boxerville given that it dropped 18 degrees by 7:00 p.m., and the temperature at 7:00 p.m. is 64 degrees. To solve this, we simply need to add the 18-degree drop back to the 7:00 p.m. temperature to find the original temperature at 4:00 p.m.
To find the temperature at 4:00 p.m., we calculate:
Temperature at 7:00 p.m.: 64 degrees
Temperature drop: 18 degrees
Original temperature at 4:00 p.m.: 64 degrees + 18 degrees = 82 degrees
Therefore, the temperature at 4:00 p.m. was 82 degrees.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line will be y=3x+6.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is constant.
Since the line is parallel to y=3x+2, the slope of the line will be the same as this line, therefore, will be equal to 3. The equation of the required line will be,
y = 3x + c
Now, the value of constant, c can be found by substituting the point in the equation of the line, therefore,
9 = 3(1) + c
9 = 3 + c
c = 6
Hence, the equation of the line will be y=3x+6.

Answer:
B. 2005
Step-by-step explanation:
We have been given that population of deer in a certain national park can be approximated by the function [tex]P(x)=150(1.07)^x[/tex], where x is the number of years since 1995. We are asked to find the year in which population will reach 300.
To solve our given problem, we will equate [tex]P(x)=300[/tex] and solve for x as:
[tex]300=150(1.07)^x[/tex]
[tex]\frac{300}{150}=\frac{150(1.07)^x}{150}[/tex]
[tex]2=(1.07)^x[/tex]
Now, we will take natural log on both sides as:
[tex]\text{ln}(2)=\text{ln}((1.07)^x)[/tex]
[tex]\text{ln}(2)=x\text{ln}(1.07)[/tex]
[tex]x=\frac{\text{ln}(2)}{\text{ln}(1.07)}[/tex]
[tex]x=10.2447[/tex]
[tex]x\approx 10[/tex]
Now, we will find 10 years after 1995 that is [tex]1995+10=2005[/tex].
Therefore, the population will be 300 in year 2005 and option B is the correct choice.
Chandler is walking 1/16 km every 10 minutes. How many kilometers will he walk in 1 hour?!
Answer:
[tex]\frac{3}{8} or\ 0.375\ km[/tex]
Step-by-step explanation:
Given: Chandler walk 1/16 km every 10 minutes.
First, lets find how many 10 minutes in one hours or convert minutes in hours.
∴ Time= [tex]\frac{60}{10} \ h[/tex]
Now, finding kilometres travelled in 1 hour.
Distance travelled= [tex]\frac{1}{16} \times \frac{60}{10} = \frac{1}{16} \times 6[/tex]
Distance travelled = [tex]\frac{3}{8}[/tex]
