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?
Answers
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

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.

In 8 days, the temperature dropped 12 degrees. If the temperature changed at the same rate for all the days what was the change in temperature per day?
Answers
Answer:
1.5° per day
Step-by-step explanation:
Given that :
Total temperature change = drop by 12°
Number of days for the change = 8 days
Rate at which temperature changed is constant
Change in temperature per day :
Total change in temperature / number of days
12° / 8
= 1.5° per day

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.

plz tell formula of Cotθ plz fully explain
Answers
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.

What is the constant of proportionality expressed as miles per second?
Answer: The constant of proportionality is _____________miles per second.
Answers
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.
