is the constant of proportionality (unit rate per hour)?
The required constant of proportionality is 5.
A graph is shown, we have to find out the constant of proportionality.
In the given case, the constant of proportionality is given by the slope of the curve.
So, the slope is given as,
m = rise/run
From the graph put the value for any point, we choose (2, 10)
So,
m = 10/2
m = 5
Thus, the required constant of proportionality is 5.

p, q and r are prime numbers such that pqr3=270.
Work out the values of p, q and r.
b. Work out the highest common factor of 270 and 105.
The highest common factor of 270 and 105 is 15.
How to find the highest common factorfinding the prime factorization of 270.
The prime factorization of 270 can be written as:
270 = 2 * 3^3 * 5
From the equation pqr^3 = 270, we can see that p, q, and r are prime numbers. Therefore, p must be 2, q must be 3, and r must be 5.
So the values of p, q, and r are:
p = 2
q = 3
r = 5
Moving on to part B, let's work out the highest common factor (HCF) of 270 and 105.
The prime factorization of 270 is:
270 = 2 * 3^3 * 5
The prime factorization of 105 is:
105 = 3 * 5 * 7
To find the HCF, we need to find the common factors and choose the highest one.
The common factors of 270 and 105 are 3 and 5.
The highest common factor of 270 and 105 is 3 * 5 = 15.
Therefore, the highest common factor of 270 and 105 is 15.

The missing sides of the triangle are given as follows:
[tex]SX = 4\sqrt{3}[/tex]RS = 12.What are the trigonometric ratios?The three trigonometric ratios are the sine, the cosine and the tangent of an angle, and they are obtained according to the formulas presented as follows:
Sine = length of opposite side to the angle/length of hypotenuse of the triangle.Cosine = length of adjacent side to the angle/length of hypotenuse of the triangle.Tangent = length of opposite side to the angle/length of adjacent side to the angle = sine/cosine.For the angle of 30º, we have that:
6 is the opposite side.RS is the hypotenuse.Hence the hypotenuse RS is obtained as follows:
sin(30º) = 6/RS
1/2 = 6/RS
RS = 6 x 2
RS = 12.
Applying the cosine, we have that:
cos(30º) = 6/SX
[tex]\frac{\sqrt{3}}{2} = \frac{6}{SX}[/tex]
[tex]SX = \frac{12}{\sqrt{3}}[/tex]
[tex]SX = 4\sqrt{3}[/tex]

Step-by-step explanation:
Select the correct answer. Consider this quadratic equation. x2 + 1 = 2x – 3 Which expression correctly sets up the quadratic formula? A. B. C. D.
The expression x = (2 ± √(-12)) / 2 is negative, this quadratic equation does not have real solutions.
The quadratic formula, we need the quadratic equation in the form ax^2 + bx + c = 0. The given equation is x^2 + 1 = 2x - 3. To set it up correctly, we need to move all terms to one side of the equation to have a zero on the other side.
Rearranging the equation, we get x^2 - 2x + 4 = 0. Now we can identify the coefficients a, b, and c.
The correct expression to set up the quadratic formula is:
B) x = (-b ± √(b^2 - 4ac)) / (2a)
For the equation x^2 - 2x + 4 = 0, we have:
a = 1
b = -2
c = 4
Plugging these values into the quadratic formula, we have:
x = (-(-2) ± √((-2)^2 - 4 * 1 * 4)) / (2 * 1)
Simplifying further, we get:
x = (2 ± √(4 - 16)) / 2
x = (2 ± √(-12)) / 2
Since the expression inside the square root is negative, this quadratic equation does not have real solutions.

You are in a competition that involves building card towers. The quickest person to reach 100 stories wins the competition. After reaching 5 stories of cards as shown in the picture below, you needed to use 40 cards.
How many cards will be necessary to build , in a similar way, a tower with 100 stories. Make sure you include work.
Answer:
To determine the number of cards necessary to build a tower with 100 stories, let's analyze the pattern observed in the given information.
From the information provided, we know that building 5 stories of cards required 40 cards. Now, let's examine the relationship between the number of stories and the number of cards used:
Number of stories: 5
Number of cards used: 40
To find the number of cards needed for 100 stories, we can calculate the ratio of the number of stories to the number of cards used for the 5-story tower and then apply that ratio to the target number of stories (100).
Ratio = Number of stories / Number of cards used
Ratio = 5 / 40
Now, we can use this ratio to calculate the number of cards needed for 100 stories:
Number of cards for 100 stories = Ratio * Number of stories
Number of cards for 100 stories = (5 / 40) * 100
Calculating the result:
Number of cards for 100 stories = (0.125) * 100
Number of cards for 100 stories = 12.5
Since it is not possible to use a fraction of a card, we need to round up to the nearest whole number. Therefore, we would need a minimum of 13 cards to build a tower with 100 stories using a similar pattern.
Please note that the actual number of cards required may vary depending on the specific construction technique and stability of the tower.

when the velocity is 348 meters per second, the approximate temperature is 18 degrees Celsius.
How to find the temperature when the velocity is 348 meters per secondTo find the temperature when the velocity is 348 meters per second, we can substitute the given velocity into the equation v = 20√273 + t and solve for t.
Given: v = 348 meters per second
Substituting this value into the equation:
348 = 20√273 + t
Now, let's solve for t. We can start by isolating the term with t:
t = 348 - 20√273
Calculating the value:
t ≈ 348 - 20 * 16.523
t ≈ 348 - 330.46
t ≈ 17.54
Rounding the answer to the nearest degree, we have:
t ≈ 18 degrees Celsius
Therefore, when the velocity is 348 meters per second, the approximate temperature is 18 degrees Celsius.
