Why is the green triangle not possible given an angle of 30°?
The reason why the green triangle is not possible given an angle of 30° and a side length of 8.73 is due to the fact that the green triangle violates the triangle inequality theorem.
What is triangle inequality theorem?According to the triangle inequality theory, any triangle's lengths of any two sides must add up to more than the length of the third side.
The triangle inequality theorem is broken in the instance of the green triangle if the second side is extended to a very long length, making the triangle's lengths of the two shorter sides (7 and 8.73) less than the length of the longer side (24).
The orange triangle, which has side lengths of 7, 15, and roughly 16.16 (determined using the Pythagorean equation), is the only one that can exist because the green triangle is impossible.

IF I A LIQUID IS AT A TEMPERATURE OF 16.9 AND RISES AT A RATE OF 2.3 AND A SOLID IS AT A TEMPERATURE OF 30.7 AND DECREASES AT A RATE OF 6.9 how long will it take for them to be at the same temperature in minutes
Answer:
The number of minutes it will take for a liquid and a solid to reach the same temperature is 3 minutes.
Step-by-step explanation:
You know that the temperature of liquid at 16.9°C is decreasing at a rate of 2.3°C per minute. Then, the temperature of the liquid after t minutes, as its value decreases, will be the difference between the initial temperature of 16.9 ° C and the temperature after t minutes. So:
temperature of the liquid= 16.9°C - 2.3 °C/minute * t
On the other side, you know that the temperature of a solid at 30.7°C is decreasing at a rate of 6.9°C per minute. Then, the temperature of the solid after t minutes, as its value decreases, will be the difference between the initial temperature of 30.7°C and the temperature after t minutes. So:
temperature of the solid= 30.7°C - 6.9 °C/minute * t
You want to calculate the number of minutes it will take for a liquid and a solid to reach the same temperature. This is:
temperature of the liquid= temperature of the solid
16.9°C - 2.3 °C/minute * t= 30.7°C - 6.9 °C/minute * t
Solving:
- 2.3 °C/minute * t= 30.7°C - 6.9 °C/minute * t - 16.9°C
- 2.3 °C/minute * t + 6.9 °C/minute *t= 30.7°C - 16.9°C
4.6 °C/minute * t = 13.8 °C
t=3 minutes
So the number of minutes it will take for a liquid and a solid to reach the same temperature is 3 minutes.

6 foot tall adult casts, a shadow that is 15 feet long estimate the height of a child who cast a 10 foot shadow
By similarity of triangle the height of a children will be 4ft.
What is similarity of triangle?Similar triangles are that kind of triangles that have the same shape, but different sizes. examples of similar objects are All equilateral triangles, squares of any side lengths. In another words, if two triangles having their corresponding angles are congruent and corresponding sides are in equal proportion then two triangles are said to be similar. It is denoted by ‘~’ symbol.
We can use the property of similar triangles to estimate the height of the child:
The ratio of the height of the adult to the length of their shadow is the same as the ratio of the height of the child to the length of their shadow:
height of adult / length of adult shadow = height of child / length of child shadow
Plugging in the values we know:
6 / 15 = height of child / 10
Solving for the height of the child:
height of child = (6 / 15) * 10 = 4 feet
Therefore, the estimated height of the child is 4 feet.

What is a scale factor?In mathematics, a scale factor is a constant that multiplies every length of an object, changing its size while preserving its shape. In the context of dilation, which is a type of transformation that changes the size of a shape, the scale factor determines the amount by which the shape is enlarged or reduced.
When a shape is dilated with a scale factor greater than 1, the resulting shape is larger than the original. Conversely, when a shape is dilated with a scale factor between 0 and 1, the resulting shape is smaller than the original. If the scale factor is exactly 1, then the shape remains the same size.
In the problem the image is dilated with a scale factor less than one hence the resulting image is lesser

7. The ride length of a roller coaster is 314
minutes. Every ride starts as soon as the
previous ride ends. How many rides take place
in 28 minutes?
Answer: To find out how many rides take place in 28 minutes, we need to divide the total ride length by the length of one side, and then round down to the nearest whole number.
The length of one ride can be calculated by dividing the total ride length by the number of rides. Since we don't know the number of rides, let's call it "n":
length of one ride = total ride length / n
314 minutes / n
Now we can set up an equation to solve for "n":
28 minutes = length of one ride * number of rides
28 minutes = (314 minutes / n) * number of rides
We can simplify this equation by multiplying both sides by "n":
28 minutes * n = 314 minutes * number of rides
Dividing both sides by 314 minutes, we get:
n = (28 minutes * number of rides) / 314 minutes
Multiplying both sides by 314 minutes and dividing by 28 minutes, we get:
number of rides = (n * 314 minutes) / 28 minutes
number of rides = 11.21
Rounding down to the nearest whole number, we get:
number of rides = 11
Therefore, in 28 minutes, 11 rides take place.

What is the vertex fοrm?The vertex fοrm οf a quadratic functiοn is a way οf writing a quadratic functiοn in the fοrm: f(x) = a(x - h)² + k, where (h, k) is the vertex οf the parabοla, a is a cοefficient that determines the shape and directiοn οf the parabοla, and x is the input variable. This fοrm is called the vertex fοrm because it prοvides direct infοrmatiοn abοut the vertex οf the parabοla, which is the pοint where the parabοla changes directiοn.
Tο rewrite the quadratic functiοn f(x) = x² - 4x + 49 frοm standard fοrm tο vertex fοrm, we need tο cοmplete the square by adding and subtracting a cοnstant term inside the parentheses, such that the functiοn can be expressed in the fοrm a(x - h)² + k.
f(x) = x² - 4x + 49
We can cοmplete the square as fοllοws:
f(x) = (x² - 4x + 4) + 45
= (x - 2)² + 45
Therefοre, the vertex fοrm οf the functiοn f(x) is:

The volume integral for f(x,y,z) = 1 over the region E : x² + y² + z² ≤ 4,
1) In spherical coordinates system is
[tex]V = {\int_{0}^{2π} \int_{0}^{π} \int}_{0}^{2} \rho^{2} \sin( \phi) \: d\rho d\phi d\theta[/tex]
2) In cylinderical coordinates system is

3) In rectangular coordinates syatm is

We pick a region E : x² + y² + z² ≤ 4 and determine volume over the region E for function, f(x,y,z ) = 1 .
Use of Spherical coordinates (ρ,θ, φ), Volume can be written as[tex]V = {\int \int \int}_{E} f(x,y,z) dV[/tex]
In spherical coordinates system we plug,
[tex]x = \rho sin \phi cos \theta[/tex]
[tex]y = \rho sin \phi sin \theta[/tex]
[tex]z = \rho cos \phi [/tex]
[tex]dV = dx dy dz = |J| d\rho d\phi d\theta [/tex]
where, [tex]|J| = \rho² sin \phi[/tex]
=> [tex]dx dy dz = \rho² sin \rho d\rho d\phi d\theta[/tex]
So, [tex]V = {\int \int \int}_{x² + y² + z² ≤ 4} 1 \: dxdy dz[/tex]
Now, [tex]V = {\int_{0}^{2π} \int_{0}^{π} \int}_{0}^{2} \rho^{2} \sin( \phi) \: d\rho d\phi d\theta[/tex]
Using Cylindrical coordinates (r,θ,z)Region , E : x² + y² + z² ≤ 4
=> z² ≤ 4 - x² - y²
=> z ≤ ± √4 - x² - y²
[tex]V = {\int \int_{ x² + y² ≤ 4} \int}_{ - \sqrt{ 4 - x² - y²}}^{ \sqrt{4 - {x}^{2} - {y}^{2} } } 1 \: dz dx dy \\ [/tex]
here, r∈[0, 2], θ∈[0,2π]
[tex]V = \int_{0}^{2π} \int_{0}^{2} (\int_{-\sqrt {4 - x² - y²}}^{\sqrt{ 4 - x² - y²}} dz) rdr d \theta \\ [/tex]
Using rectangular coordinates (x,y,z), Volume integral can be written as :[tex]V = {\int \int \int}_{E} f(x,y,z) dV[/tex]
[tex]V = {\int \int_{ x² + y² ≤ 4} \int}_{ - \sqrt{ 4 - x² - y²}}^{ \sqrt{4 - {x}^{2} - {y}^{2} } } 1 \: dz dx dy \\ [/tex]
Here, y² ≤ 4 - x²
=> y = ± √4 - x² and x∈ [0,2], So,
[tex]V = \int_{0}^{2}\int_{ -\sqrt {4 - x²}}^{\sqrt{4 - x²}} \int_{ - \sqrt{ 4 - x² - y²}}^{ \sqrt{4 - {x}^{2} - {y}^{2} } } \: dz dy dx \\ [/tex]

given the equations below what is the frist x value where g(x)>f(X)
f(X)=4X=25
g(X)=2(5)x
Answer:There seems to be a typo in the equation for f(x). I will assume that the correct equation is:f(x) = 4x - 25To find the first x value where g(x) > f(x), we can set the two equations equal to each other and solve for x:g(x) = f(x)
2(5)x = 4x - 25
10x = 4x - 25
6x = -25
x = -25/6
Step-by-step explanation:However, we need to check if this value satisfies the condition g(x) > f(x):g(-25/6) = 2(5)(-25/6) = -25
f(-25/6) = 4(-25/6) - 25 = -75/3 - 25/1 = -100/3Therefore, g(x) > f(x) is not true for x = -25/6. We need to keep looking for a larger value of x where g(x) > f(x).To do this, we can graph the two functions and look for the point where the graph of g(x) is above the graph of f(x). Alternatively, we can simply plug in some larger values of x and compare the values of g(x) and f(x) until we find the first x value where g(x) > f(x).Let's try plugging in x = 0:g(0) = 2(5)(0) = 0
f(0) = 4(0) - 25 = -25Since g(0) = 0 and f(0) = -25, we have g(x) > f(x) for x > 0. Therefore, the first x value where g(x) > f(x) is x = 0.

Answer:
Samedy's statement is false. in total the class has 56 brothers and sisters
Step-by-step explanation:
Answer:
A. Samedy's statement is incorrect.
B. In total, the class has 71 brothers and sisters.
To arrive at this answer, we can use the information given in the problem to calculate the total number of brothers and sisters:
7 students have 2 siblings each, so there are 14 siblings in total.
4 students have 1 sibling each, so there are 4 siblings in total.
6 students have 3 siblings each, so there are 18 siblings in total.
The remaining students have 4 siblings each, so there are 4 x (24 - 7 - 4 - 3 - 6) = 4 x 4 = 16 siblings in total.
Adding all of these up, we get a total of 14 + 4 + 18 + 16 = 52 siblings. Therefore, Samedy's statement is incorrect, as the class has 52 siblings and not 24.

A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken.
Find the probability that the mean actual weight for the 100 weights is greater than 24.9. (Round your answer to four decimal places.)
Thus, the chance according to the equation that the average actual weight for the [tex]100 weights[/tex] is higher than [tex]24.9 pounds[/tex] is roughly [tex]0.9582[/tex]
What is equation?An equation in mathematics is a declaration of the equivalence of two expressions. Two parts of an equation are divided by the algebraic symbol ([tex]=[/tex]). As an example, the assertion "[tex]2x+3=9[/tex]" is supported by the argument that it is true.
Finding the value or values of the variable(s) needed to make the equation correct is the aim of equation solving. It is possible to create regular or nonlinear, straightforward or complex equations that include one or more variables.
For instance, the variable[tex]x[/tex] is raised to the second degree in the equation "[tex]x^{2} +2x-3[/tex]". In many areas of mathematics, such as algebra, calculus, or geometry, lines are used.
The weights are distributed evenly, with a minimum value of [tex]24[/tex] and a highest value of [tex]26[/tex]. The average of the lowest and maximum values, which is the mean weight of a single weight, is
[tex](mean weight)= (24+26)/2 = 25 pounds[/tex]
The standard deviation of a single weight is the difference between the maximum and minimum values divided by[tex]\sqrt{12}[/tex] (since there are [tex]12[/tex]possible values between [tex]24[/tex] and [tex]26[/tex]), which is
[tex]Standard deviation = (24+26)/\sqrt{12}[/tex]
[tex]We know (standard deviation of mean weight ) = 0.57735/\sqrt{100} =0.057735[/tex]
We must standardise this value by taking the mean weight, subtracting it, and dividing the result by the mean weight's standard deviation in order to determine the likelihood that the mean actual weight for the[tex]100[/tex]weights is higher than [tex]24.9 pounds[/tex]:
[tex]( Z- score )= (24.9-25)/0.057735 = -1.7321[/tex]
Probability is [tex]less than[/tex] [tex]-1.7321 in Z- score approx 0.0418[/tex]
However [tex]mean actual weight > 24.9[/tex] which is the complement of the probability i.e, [tex]\leq 24.9[/tex]
After subtracting the probability we found [tex]1[/tex] [tex](mean weight > 24.9)[/tex]
∴[tex]1 -0.0418 = 0.9582[/tex]
Therefore the the average actual weight for the [tex]100 weights[/tex] is higher than [tex]24.9 pounds[/tex] is roughly [tex]0.9582[/tex]

The rectangle's area is growing at a pace of 138 [tex]\frac{cm^{2} }{s}[/tex] when its length is 10 cm and its width is 6 cm, this is the case.
What is the rate of change?One quantity's rate of change with regard to another quantity is known as the rate of change function. In order to calculate the rate of change, one simply divides the amount of change in one item by the equivalent amount of change in another.
Let L and W represent the length and breadth of the rectangle, respectively, and A represents the area of the rectangle. Next, we have:
A = L * W
When L = 10 cm and W = 6 cm, we are interested in determining the rate of increase of the rectangle's area with regard to time, or dA/dt.
We can begin by finding the derivative of A = L * W with regard to time t for both sides of the equation:
Derivate the equation by both sides with respective t.
[tex]\frac{d}{dt} (L * W) = \frac{dA}{dt}[/tex]
Using the principle of product rule of derivative, we arrive at:
[tex]L * W + L * \frac{dw}{dt} = \frac{dA}{dt}[/tex]
To determine dA/dt when L = 10 cm and W = 6 cm, we are provided that [tex]\frac{dL}{dt}[/tex] = 8 cm/s and [tex]\frac{dw}{dt}[/tex]= 9 cm/s. Therefore, we replace these numbers in the previous equation to obtain:
[tex]\frac{dA}{dt}[/tex] = (8 [tex]\frac{cm}{s}[/tex]) * (6 cm) + (10 cm * 9 [tex]\frac{cm}{s}[/tex]).
[tex]\frac{dA}{dt} = 48 \frac{cm^{2}}{s} + 90 \frac{cm^{2}}{s} \\[/tex]
[tex]138 \frac{cm^{2} }{s} = \frac{dA}{dt}[/tex]
Since the rectangle's area is growing at a pace of 138 [tex]\frac{cm^{2} }{s}[/tex]when its length is 10 cm and its width is 6 cm, this is the case.

What is the area of this composite figure? Use 3.14 for pi. Round to the nearest hundredth. Show ALL work.
The composite figure compromising of a sector, a triangle and a trapezoid have a total area calculated to be 15.9 square units.
How to find the area of the composite figureWe can observe from the figure that it is a combination of a sector, a triangle and a trapezoid, so we shall calculate the area of each shape and add their result to get the area of the composite figure as follows:
area of the sector = 135°/360° × 22/7 × 2 × 2
area of the sector = 33/7
area of the sector = 4.7 square units
area of triangle = 2.6 × 1
area of the triangle = 2.6 square units
area of the trapezoid = 1/2 × (2.6 + 6) × 2
area of the trapezoid = 8.6 square units
area of the composite figure = 4.7 + 2.6 + 8.6
area of the composite figure = 15.9 square units
In conclusion, the composite figure compromising of a sector, a triangle and a trapezoid have a total area calculated to be 15.9 square units.

Riley recorded which type of guitar each contestant played. He also counted the number of contestants wearing different kinds of pants, as there were some interesting stylistic choices.
What is the conditional probability that a randomly selected contestant played an acoustic guitar, given they wore leather pants?
A. 9/25
B. 2/5
C. 3/5
D. 6/25
show all steps
The conditional probability that a randomly selected participant wore leather pants and played an acoustic guitar is 6/25. Therefore, the answer is option D. 6/25.
What is conditional probability?Conditional probability is the probability that an event will occur given that another event has already occurred.
It is denoted by P(A|B), where A and B are events, and the vertical line | indicates "given that" or "conditional on".
The conditional probability of an event A given event B is defined as the probability of both A and B happening divided by the probability of B happening:
P(A|B) = P(A and B) / P(B)
In this case, the event A is playing an acoustic guitar and the event B is wearing leather pants.
We can start by finding the probability of wearing leather pants:
P(B) = (6 + 9) + (3 + 7) = 25
This is because there are a total of 6 contestants wearing leather pants and 19 contestants in total.
Next, we need to find the probability of both wearing leather pants and playing an acoustic guitar:
P(A and B) = 6
This is because there are 6 contestants wearing leather pants and playing an acoustic guitar.
Now we can use the formula to find the conditional probability:
P(A|B) = P(A and B) / P(B) = 6 / 25

In an Australian netball competition, these teams are tipped to win Round 1 by three experts:
Expert A: NSW, Queensland, WA, Tasmania
Expert B: SA, Victoria, Queensland, WA Expert C: NSW, ACT, WA, Victoria No one tipped the Northern Territory to win. Which team did Victoria play?
Answer:
undetermined or most likely Tasmania
Step-by-step explanation:
Based on the choices of experts in the first round of the Australian netball competition, we can conclude that Victoria played against WA. This is because, out of the common tips, WA was tipped by an expert who also tipped Victoria and didn't tip Queensland. Therefore, WA is the likely team that Victoria played against.
Explanation:To identify which team Victoria played in the Australian netball competition we can reason through our experts' tips. The experts' tips overlap at Queensland and WA as indicated by Expert A and Expert B. However, Expert C tipped Victoria, and they did not tip Queensland which tells us that Victoria did not play against Queensland, leaving us with WA. Hence Victoria must've played against WA.
