A team of storm enthusiasts collected data to show the relationship between the time between seeing lightning and then hearing thunder, and how far away you are from the lightning. The results are in the graph below.
What is the constant of proportionality expressed as miles per second?
Answer: The constant of proportionality is _____________miles per second.
Answer:
Proportionality constant = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
From the graph attached,
Data set representing the relation between seeing lightning and the hearing thunder is,
{(15, 3), (25, 5), (35, 7), (45, 9)}
Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)
d = kt
Here k = proportionality constant
k = [tex]\frac{d}{t}[/tex]
From the data set one point is (15, 3).
k = [tex]\frac{3}{15}[/tex]
k = [tex]\frac{1}{5}[/tex] miles per second
Therefore, proportionality constant is [tex]\frac{1}{5}[/tex] miles per second.

What is the solution to the equation below?
2(x – 3) = 2x + 5
show your work
Answer:
2(x - 3) = 2x + 5
Multiply out the left side:
2x - 6 = 2x + 5
Subtract 2x from both sides:
-6 = 5
Since this is impossible, this "equation" cannot be solved.

Three pipes A, B and C take 24, 36 and 32 hours to fill a pool, respectively. How long would it take the three pipes to fill the pool if pipe B is turned on 3 hours after pipe A and pipe C is turned on 1 hour after pipe B?
Answer:
12 hours
Step-by-step explanation:
Time taken by pipe A = 24 hours
Time taken by pipe B = 36 hours
Time taken by pipe C = 32 hours
To find:
How long would it take the three pipes to fill the pool if pipe B is turned on 3 hours after pipe A and pipe C is turned on 1 hour after pipe B?
Solution:
First of all, let us assume the total capacity of the pool.
Let us take LCM of 24, 36 and 32.
LCM of 24, 36 and 32 = 288
Let the total capacity of the pool = 288 units
Total units filled by pipe A in one hour = [tex]\frac{288}{24} = 12\ units[/tex]
Total units filled by pipe B in one hour = [tex]\frac{288}{36} = 8\ units[/tex]
Total units filled by pipe C in one hour = [tex]\frac{288}{32} = 9\ units[/tex]
Now, for the first 3 hours, only pipe A operates, so units filled in first three hours = [tex]12\times 3 =36\ units[/tex]
For the next one hour, A and B both operate together, so units filled in the next 1 hour = 12 + 8 = 20 units
Total number of units filled in 4 hours = 36 + 20 = 56 units
Units to be filled to completely fill the pool = 288 - 56 = 232 units
Now, after the 4th hours, all the pipes operate together.
So, number of units filled in each hour = 12 + 8 + 9 = 29 units
Time taken to fill 232 units = [tex]\frac{232}{29} = 8\ hours[/tex]
Total time taken = 4 + 8 = 12 hours

Step-by-step explanation:
The Sandoval family paid $180 for 2 adult tickets and 3 child tickets to an amusement park. The Martinez family paid $105 for 1 adult and 2 child tickets to the same park. What is the price of a child ticket?
Answer: The cost of a child ticket is $30
Step-by-step explanation:
Let's define the variables:
A = price of an adult ticket
C = price of a child ticket
We know that:
"The Sandoval family paid $180 for 2 adult tickets and 3 child tickets to an amusement park."
This means that:
2*A + 3*C = $180
and
"The Martinez family paid $105 for 1 adult and 2 child tickets to the same park."
This means that:
1*A + 2*C = $105
Then we have a system of equations:
2*A + 3*C = $180
1*A + 2*C = $105
To solve this, the first step is to isolate one variable in one of the equations, i will isolate A in the second equation:
A = $105 - 2*C
Now we can replace this in the other equation:
2*($105 - 2*C) + 3*C = $180
Now let's solve this for C, the price of a child ticket.
2*($105 - 2*C) + 3*C = $180
$210 - 4*C + 3*C = $180
$210 - C = $180
-C = $180 - $210
-C = - $30
C = $30
The cost of a child ticket is $30

plz tell formula of Cotθ plz fully explain
Answer:
1. cos(2π + θ) = cosθ
2. tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
explanation:
cot(2π + θ) = cotθ. The Trigonometric ratios of angle 2π - θ: Thinking of θ as an acute angle, 2π -θ ends in the 4th Quadrant where only cosine is positive. 2π -θ means going 1 full turn from A to A and then returning to the M' that means as much as θ.
Answer: cos(2π + θ) = cosθ, tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.

33÷9=3.66
366.6%
Answer:
33/9, or 11/3 (Simplified)
Step-by-step explanation:
Since the question is the ratio of plums to apples, the plums will be on top and the apples on bottom. It is 33 to 9, or 33/9, but this can be simplified to 11/3.

Does anyone know the correct choice for this question? If its correct ill mark you as the best answer choice!
Answer:
Therefore, the line's equation and the correct slope will be:
[tex]y = 3, m = 0[/tex]
Therefore, option J is correct.
Step-by-step explanation:
As the line is perpendicular to the y-axis means the line is parallel to the x-axis.
i.e. m = 0As the line passes through (2, 3)so according to the point slop form
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y - 3 = 0 (x - 2)[/tex]
[tex]y - 3 = 0 - 0[/tex]
[tex]y = 3[/tex]
Therefore, the line's equation and the correct slope will be:
[tex]y = 3, m = 0[/tex]
Therefore, option J is correct.

Answer:
A. 100 per deposit
Step-by-step explanation:
for every one deposit made, you see your y value increasing by 100
Answer: Choice A is correct
=================================================
Explanation:
Each time x goes up by 1, y goes up by 100 (eg: from 50 to 150, so 150-50 = 100).
We then say,
slope = rise/run
slope = (change in y)/(change in x)
slope = (100)/(1)
slope = 100
The rate of change is $100 per deposit
------------------------------
We could also use the slope formula. Pick any two points on the diagonal line. Let's say we picked (1,150) and (3,350)
m = (y2-y1)/(x2-x1)
m = (350-150)/(3-1)
m = (200)/(2)
m = 100
Or we could pick (0,50) and (1,150) as our two points
m = (y2-y1)/(x2-x1)
m = (150-50)/(1-0)
m = (100)/(1)
m = 100
Either way, the slope is m = 100.
