The height in inches, h, of s sheets of paper can be described by the equation h=0.004s. What does the 0.004 mean in this situation?
The "0.004" is the constant of proportionality, in this particular case, that value represents the height if a single sheet of paper.
What does the 0.004 mean in this situation?We know that the height, in inches, of s sheets of paper can be described by the equation:
h = 0.004*s
So, if we have a single sheet, the height is:
h = 0.004*1 = 0.004
The height of a single sheet if 0.004 inches.
If instead we have two, then s = 2, we will have:
h = 0.004*2 = 0.008
The height is 0.008 inches.
So, the given equation:
h = 0.004*s
Is a proportional relation.

The possible coordinates of point G on the number line is -15 and 7.
How to find the coordinates on a number line?On the number line, point E has the coordinates of - 4, and EG = 11 .
The possible coordinates of point G are as follows:
A number line is a horizontal straight line with numbers placed at equal distances from each other along that line.
Negative numbers are on the left side while the positive numbers are on the right side.
Therefore, the possible coordinates of G is when we go left or right side of E on the number line.
Hence,
Let's go left E to G on the number line
-4 - 11 = -15Let's go right E to G on the number line
-4 + 11 = 7Therefore, the possible coordinates of point G on the number line is -15 and 7.

what is the equation for the standard form of the line that has an x-intercept of 3 and a y-intercept of 5
5x+3y=15 is the equation for the standard form of the line .
What is in slope-intercept form?
Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form. Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.We are given two coordinates (3,0) (0,5)
Start by finding slope
y2-y1/x2-x1= 5-0/0-3= -5/3 this is your slope m.
y=mx+c
y= -5/3x+c (but remember standard line is ax+by=c) so we have to switch sides
5/3x + y=5 (remember standard form has no fraction so multiply by 3 on all sides)

If P(-3, 6) is tranlated 4 units up and 8 units down what are the coordinates of P?????
The coordinates of P' is (-3,2).
Given that P(-3, 6) is translated 4 units up and 8 units down.
The translation of a point involves moving it a certain distance horizontally and/or vertically. You can find the address of a translated point like this:
To translate a point to the right, add the translation to the x-value.To translate a point to the left, subtract the translation from the x value.To translate a point up, add the translation to the y-value.To translate a point down, subtract the translation from the y-value.The point P(-3,6) is shown in blue above.
Travel 4 unit to the up and 8 units down from point P, and you arrive at point P'(-3,2), shown in red.
Hence, the coordinates of P' when P(-3, 6) is translated 4 units up and 8 units down is P'(-3,2).

Find the tenth term of each arithmetic sequence. 2,8,14,20, ...........
The 10th term of the given arithmetic sequence 2,8,14,20, ........... is ( a₁₀ = 56.)
Describe the AP arithmetic progression series?The difference between two mathematical orders is a fixed value in Arithmetic Progression (AP). Arithmetic Sequence is another term for it.
We'd come across a few key words in AP which have been classified as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP can also be viewed in terms of common differences, as illustrated below.
The following is the process for evaluating an AP's n-th term: an = a + (n − 1) × dThe so these is the arithmetic progression sum: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the sequence given in the question is; 2,8,14,20, ...........
Define the first term as 'a₁' = 2.
Define 'a₂' = 8 is the second term.
Define the third term as 'a₃' = 14.
Evaluate the common difference;
d = a₂ - a₁
Put the values in the obtained equation;
d = 8 - 2 = 6
Now, to evaluate the value of the 10th term imply the formula of nth term.
an = a + (n − 1) × d , n = total number of terms = 10.
Substitute all the values;
a₁₀ = 2 + (10 - 1) × 6
a₁₀ = 2 + 9 × 6
a₁₀ = 2 + 54
a₁₀ = 56.
Therefore, the value of the 10th term is found as a₁₀ = 56.

A = 179 + ( 0.14 x 179 ) x
A = 204.06x
B = ( 169 + ( 0.18 x 169 )x + 40
B = 199.42x + 40
Equate the two equations:-
204.06x = 199.42x + 40
4.64x = 40
x = 40 / 4.64
x = 8.62 nights

Use the given information to write an equation of the circle.
center (6,4) , through (2,1)
Using the given information, the equation of the circle with center located at point (6 , 4) and passes through the point (2 , 1) is (x - 6)^2 + (y - 4)^2 = 25.
Using the distance formula, get the radius of the circle by solving for the distance between the center (6 , 4) and the point (2 , 1).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(2 - 6)^2 + (1 - 4)^2
radius= √16 + 9
radius = √25
radius = 5
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (6 , 4)
r = 5
(x - 6)^2 + (y - 4)^2 = 5^2

Rewrite x4y2-6x3y3 using a common factor
Answer:
[tex]x^4y^2-6x^3y^3 = x^3y^2(x - 6y)[/tex]
Step-by-step explanation:
to pick out common factors, you have to find the highest common denominator. We start by listing units and variables:
we can divide the x^4y^2 by up to x^4 and up to y^2, cannot divide by non-variable numbers
we can divide 6x^3y^3 by up to x^3 and up to y^3, and by 6 if we needed to.
This means that for units, we're not dividing (because we can't simplify x^4y^2 dividing by a bare number.
For x, we can divide both by x^3, because we can divide both by x^3, but cannot divide 6x^3y^3 by x^4 or more.
For y, we can divide both by y^2, because we can divide both by y^2, but cannot divide x^4y^2 by x^3 or more.
We take the x^3y^2 and bring it in front of the brackets.

Find the equation for the line parallel to 3x+5y-4=0, with the same x-intercept as 2x-3y-6=0
Equation of line is 5y = -3x + 9 .
What is equation of line?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.
3x+5y-4=0
5y = -3x + 4
y = -3/5 x + 4/5
since it is parallel, its slope, m is -3/5
2x-3y-6=0
3y = 2x - 6
y = 2/3x - 2
at x-intercept, y is zero
2 = 2/3x
x = 3
therefore
y = mx + c
0 = (-3/5 * 3 ) + c
c = 9/5
equation is
y = -3/5x + 9/5

A sequence is a sequence of things (usually numbers) in order 3, 5, 6, 7, 8, and so on. A geometric sequence is known as a particular type of sequence ]. A sequence multiplies each term (except the first) by a constant to get the next term in the sequence. So, from the information, we can conclude that to get the next term in the geometric sequence, we need to multiply that with a specific term (known as the common ratio), and to find the last term in the sequence, we multiply that term by the same standard ratio. Just split it.

What exactly would be a pie chart?A pie graph is a type of chart which displays data in the form of a circular graph.
We understand that the total value of the pie is always 100%. It is also understood that a circle will have a circumference of 360°. As a consequence, the total of all data points equals 360°. There appear to be two main pie chart formulas based on these:
To evaluate a proportion of the data set, we just use following formula: (Frequency ÷ Total Frequency) × 100To transform the information to degrees, we should use following formula: (Mentioned Data ÷ Total value of Data) × 360°When a circle is completely rotated, it forms a 360-degree angle in the center.
The overall percentage of all colors is 100%.
Because 360 degrees / 100 percent = 3.6, divide the valuation of yellow by 3.6.
The total percentage of yellow displayed by the spinner's pointer is 110%.
P (probability of landing on yellow) = 110/3.6
P (probability of landing on yellow) = 30.555... = 30.56 (approx.)
As a result, the probability of the pointer landing on the yellow is 30.56%
