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.

Write in point-slope form an equation of the line through each pair of points. (1,0) and (5,5)
The equation of the line in point-slope form, which passes through the points located at (1 , 0) and (5 , 5), is y = 5/4(x - 1).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (1 , 0) and (5 , 5).
m = (y2 - y1)/(x2 - x1)
m = (5 - 0)/(5 - 1)
m = 5/4
Using the point slope form, plug in the values of the slope and one point to set up the equation.
(y - y1) = m(x - x1)
where m = 5/4 and (x1 , y1) = (1 , 0)
(y - 0) = 5/4(x - 1)
y = 5/4(x - 1)

On Monday, a bookstore sold 57 books. On Tuesday, the store sold 64 books. Let p represent the percent increase in the sale of books from Monday to Tuesday. Drag the tiles to fill in all the boxes and complete a proportion that can be used to find the value of p.
The value of the percent increase "p" is 12.28%.
Percent Increase can be calculated using the formula
Percent increase = (Amount increased/original amount) x 100
In the given question
Number of books sold on Monday = 57 books
Number of books sold on Tuesday = 64 books
Increase in number of books = books sold on Monday - books sold on Tuesday.
Substituting the values we get
Increase in number of books = 64-57 = 7
the percent increase = (7/57)x100
= 0.1228 x 100
= 12.28
Therefore , the value of the percent increase "p" is 12.28%.

Caylie's coin bank contains only dimes and nickels. The bank contains 46 coins. If 5 dimes and 2
nickels were removed, the total value of the coins would be $3.40. Find the number of nickels and the
number of dimes in the bank.
There were 29 nickels and 10 dimes in the bank.
We know that:
1 dime = 5 cents
1 nickel = 10 cents.
Also, $ 3.40 = 340 cents
Let the number of nickels be n and the number of dimes be d.
Now, we are given that:
5 dimes and 2 nickels were taken away.
So, total coins = 46 - 2 - 5 = 46 - 7
Total coins = 39
We get the equation:
n + d = 39
d = 39 - n
Now, we also know that:
5 d + 10 n = 340
d + 2 n = 68
Put the value of d, we get that:
39 - n + 2 n = 68
n = 68 - 39
n = 29
d = 39 - n
d = 39 - 29
d = 10
Therefore, we get that, there were 29 nickels and 10 dimes in the bank.

form a smimulatenous equation for : a cyclist completes a journey of 500 m in 22 seconds, part of the way at 10m/s and the remainder at 50m/s. How far does she travel at each speed?
The distance traveled in each section will be 150 meters and 350 meters.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
From a simultaneous equation for: A cyclist completes a journey of 500 m in 22 seconds, part of the way at 10m/s and the remainder at 50m/s.
Let x distance be covered with velocity 10 m/s in time t₁ and the remaining distance (500 - x) covered with velocity 50 m/s in time t₂. Then the equation will be
t₁ + t₂ = 22 ....1
Then the time t₁ will be
10 = x / t₁
t₁ = x / 10
Then the time t₂ will be
t₂ = (500 - x) / 50
Put the time in equation 1, then we have
x / 10 + (500 - x) / 50 = 22
5x + 500 - x = 1100
4x = 600
x = 150 meters
And the remaining distance will be
500 - x = 500 - 150
500 - x = 350 meters
The distance traveled in each section will be 150 meters and 350 meters.

The measurement of each angle is : m∠A = 108° , m∠B = 36° , m∠C = 36°.
What is an isosceles triangle ?In mathematics, an isosceles triangle is a triangle in which any of the two sides are equal. Or we can say that if a triangle has at least two sides of equal length then it is known as isosceles triangle. In geometry, isosceles triangle follow the property of congruency of triangles. That means in an isosceles triangle the two angles of equal sides are congruent to each other.
In the given question,
Let m∠B = m∠C = x , where m denotes measure of angle
therefore, m∠A = 3x
According to Triangle Angle-Sum Theorem,
m∠A + m∠B + m∠C = 180
thus,
3x + x + x = 180
5x = 180
x = 36
Hence,
m∠A = 3x = 180
m∠B = 36°
m∠C = 36°
Therefore, the measure of each angle A , B and C is 180°, 36° and 36° respectively.

Determine whether each set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
4,12,14
Yes, the given set of numbers can be the measures of the sides of a triangle. The triangle is obtuse.
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
4 + 12 > 14
12 + 14 > 4
14 + 4 > 12
Hence, these set of numbers can be the measures of the sides of a triangle.
According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:
acute if [tex]c^{2} < a^{2} + b^{2}[/tex]
obtuse if [tex]c^{2} > a^{2} + b^{2}[/tex]
right if [tex]c^{2} = a^{2} + b^{2}[/tex]
∴The longest side is 14.
Hence, a = 4, b = 12 and c = 14;
Consider [tex]a^{2} + b^{2}[/tex] :
[tex]= 4^{2} + 12^{2}[/tex]
= 160.
Now consider [tex]c^{2}[/tex] :
= [tex]14^{2}[/tex]
= 196.
Thus, [tex]c^{2} > a^{2} + b^{2}[/tex]
Hence, the triangle is obtuse.
