We can say that after answering the offered question The ladder is Pythagorean theorem therefore 15 feet long, rounded up to the next foot. Thus, 15 feet is the solution.
what is Pythagorean theorem?The Pythagorean Theorem is the foundational Euclidean geometry connection that exists between the three sides of the right triangle. According to this rule, the area of either a cube with the length x side is equal to the total of the regions of triangles shared by its other two sides. According to the Pythagorean Theorem, the square that spans the hypotenuse of a right triangle opposite the perfect angle is the combined squares that spanned its sides. It is sometimes expressed as a2 + b2 = c2 in general algebraic notation.
The ladder serves as the hypotenuse in this basic example of a right triangle, which also includes the distance from the house as one of its legs and the ladder's height as its second leg. The Pythagorean theorem can be used to find the ladder's length.
[tex]c^2 = a^2 + b^2[/tex]
In this instance, we know that the distance from the house (a) is 9 feet, and the height of the ladder (b) is 12 feet. Hence, we can enter these values into the formula as follows:
[tex]c^2 = 9^2 + 12^2 c^2 = 81 + 144\sc^2 = 225\sc = √225\sc = 15[/tex]
The ladder is therefore 15 feet long, rounded up to the next foot. Thus, 15 feet is the solution.

the ricoffy tin container no dimensions that container is 2,5 times smaller then what it is in reality the actual weight of coffees 750g , measure the diameter of the diameter of the tin in mm and write down the real diameter in mm
The required diameter of the actual Ricoffy tin container is approximately 92 mm.
Explain about Container.By enclosing units in containers—that is, by circling, boxing, or otherwise enclosing units—container numbers indicate magnitude. The worth of each container's contents is multiplied by the number system's fundamental unit. Typically, the basis is either 2 or 10 (the decimal system) (the binary system).
According to question:Let the diameter of the actual Ricoffy tin container be d mm.
Since the volume of the tin container is proportional to the cube of its dimensions, and the tin container is 2.5 times smaller than its actual size, we have:
[tex]$(\frac{d}{2.5})^3 = \frac{1}{2.5} \times d^3 = \frac{3}{4} \times 750\text{ g} = 562.5\text{ g}$$[/tex]
where we have used the fact that the actual weight of the coffee is 750g.
Solving for d, we get:
[tex]$$d = \sqrt[3]{\frac{562.5\text{ g}}{\frac{1}{2.5}}} \approx 91.98\text{ mm}$$[/tex]
Therefore, the diameter of the actual Ricoffy tin container is approximately 92 mm.

A restaurant customer left $1.05 as a tip. The tax was 8% and the tip was 15% of the cost including tax.
What was the total bill?
well, the total bill doesn't include the tip, so the total bill is the cost plus the tax.
so assuming the total bill means before tax, let's call it "x", now if we apply the tax to "x", hmmm how much is 8% of "x"?
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{8\% of x}}{\left( \cfrac{8}{100} \right)x}\implies 0.08x[/tex]
so "x" plus the tax will just be x + 0.08x = 1.08x.
The tip was 15% of that 1.08x, and we happen to know that was $1.05.
[tex]\begin{array}{ccll} Amount&\%\\ \cline{1-2} 1.08x & 100\\ 1.05& 15 \end{array} \implies \cfrac{1.08x}{1.05}~~=~~\cfrac{100}{15} \\\\\\ 16.2x=105\implies x=\cfrac{105}{16.2}\implies x\approx 6.48[/tex]
A piano teacher schedules either 30-minute lessons or 60-minute lessons with her students. Last week, the teacher gave 9 lessons which lasted for a total of 7 hours. How many 30-minute lessons did the teacher give last week?
Let's use algebra to solve this problem. Let x be the number of 30-minute lessons that the teacher gave last week, and let y be the number of 60-minute lessons. We know that the teacher gave a total of 9 lessons, so we can write:
x + y = 9
We also know that the total time spent on lessons was 7 hours, which we can convert to minutes:
30x + 60y = 420
Now we have two equations with two unknowns, which we can solve using substitution or elimination. Let's use substitution:
x + y = 9 -> y = 9 - x
30x + 60y = 420 -> 30x + 60(9 - x) = 420
Simplifying and solving for x:
30x + 540 - 60x = 420
-30x = -120
x = 4
Therefore, the teacher gave 4 30-minute lessons last week. To find the number of 60-minute lessons, we can substitute x = 4 into either equation:
x + y = 9 -> y = 9 - x -> y = 9 - 4 -> y = 5
So the teacher gave 5 60-minute lessons last week.

The cοοrdinates οf the fοurth vertex οf the parallelοgram are (19/2, 19.5).
What is cοοrdinate?A spherical οr elliptical cοοrdinate system knοwn as the geοgraphic cοοrdinate system is used tο measure and transmit pοsitiοns οn Earth as latitude and lοngitude.
First, we can find the distance between pοints Y and q, which will be the same as the distance between pοints 5 and B since they are οppοsite sides οf the parallelοgram:
Distance Yq = [tex]\sqrt{[(10-8)^2 + (5-10)^2] }[/tex]
Distance Yq = [tex]\sqrt{8 + 25 }[/tex]
Distance Yq =[tex]\sqrt{ 33}[/tex]
Distance 5B = [tex]\sqrt{[(3-2)^2 + (2-3)^2] }[/tex]
Distance 5B = [tex]\sqrt{2}[/tex]
Since οppοsite sides are cοngruent, √33 = √2x, where x is the length οf the missing side οf the parallelοgram. Sοlving fοr x, we get:
x = (33/2)
Next, we can find the slοpe οf the line passing thrοugh pοints Y and q,
Slοpe Yq = (10-5)/(8-10) = -5/2
Slοpe B-missing vertex = -5/2
write the equatiοn οf the line passing thrοugh B and the missing vertex:
y - 2 = (-5/2)(x - 3)
Simplifying, we get:
y = (-5/2)x + (19/2)
Therefοre, the cοοrdinates οf the missing vertex are (19/2, x), where x = 2 + (33/2) = 19.5.

In the system shown below, how might multiplying each term in the second equation by 2 help us use elimination to solve the system of equations?
4d + 200m = 450
2d + 400m = 300
The solution to the system of equations is d = 100 and m = 1/4. Multiplying each term in the second equation by 2 helped us to eliminate the variable d and solve for m.
How to Solve a System of Equations by Elimination?To solve the system of equations, we can use the elimination method, which involves adding or subtracting the two equations to eliminate one of the variables.
In this case, if we add the two equations as they are, we won't be able to eliminate one of the variables.
Multiply each term in the second equation by 2, we will get:
4d + 200m = 450
4d + 800m = 600
Now, we can subtract the first equation from the second equation to eliminate d:
(4d + 800m) - (4d + 200m) = 600 - 450
600m = 150
m = 1/4
Substituting this value of m back into either of the original equations, we can solve for d:

The average amount of time until a car accident on a particular 60 mile stretch of road is 60 minutes. Assume (unreasonably) that car accidents are independent, and that two accidents cannot occur at the same time.
(a) What is the probability of a car accident occurring in the two hours?
(b) What is the probability of a car accident occurring between 45 and 75 minutes?
(c) What is the variance of the time until a car accident occurs?
(d) If a car accident has not happened in 3 hours, what is the probability it will happen in the next two hours?
(a) The probability of a car accident occurring in the two hours is 0.3679.(b) The probability of a car accident occurring between 45 and 75 minutes is 0.3935 (c) The variance of the time until a car accident occurs is 0.0167 d) If a car accident has not happened in 3 hours, the probability it will happen in the next two hours is 0.7385
Since the average rate of car accidents is 1/60 accidents per minute, we can use the Poisson distribution to find the probability:
[tex]P(X = 1) = (e^(-120/60) * (120/60)^1) / 1! = 0.3679[/tex]
So the probability of a car accident occurring in the two hours is 0.3679.
Since the average rate of car accidents is 1/60 accidents per minute, we can use the Poisson distribution to find the probability:
[tex]P(X = 1) = (e^(-30/60) * (30/60)^1) / 1! = 0.3935[/tex], So the probability of a car accident occurring between 45 and 75 minutes is 0.3935.
The variance of a Poisson distribution is equal to the average rate, so the variance of the time until a car accident occurs is: [tex]Var(X) = 1/60 = 0.0167[/tex]Given that no car accident has occurred in the previous 180 minutes. We can use the conditional probability formula to find this probability:
[tex]P(X = 1 | X = 0) = P(X = 1 and X = 0) / P(X = 0) = (e^(-120/60) * (120/60)^1) / (e^(-180/60) * (180/60)^0) = 0.3679 / 0.0498 = 0.7385[/tex]

In a 3-4-5 right triangle which of the following is closest to the measure of the larger acute angle in the triangle
According to the given information, the measure of the larger acute angle in the 3-4-5 right triangle is approximately 36.87 degrees.
What is 3-4-5 right angle triangle?
A 3-4-5 right triangle is a right triangle where the lengths of the three sides are in the ratio of 3:4:5. In other words, the length of the longest side (the hypotenuse) is 5 times the length of the shortest side, and the length of the remaining side is 4 times the length of the shortest side. This special right triangle has angles of 30 degrees, 60 degrees, and 90 degrees, which are the angles of a 30-60-90 triangle. The sides of a 3-4-5 right triangle can be scaled up or down by any common factor (e.g. 6-8-10, 9-12-15, etc.) and will still form a right triangle with the same angles.
In a 3-4-5 right triangle, the larger acute angle is opposite to the longer leg, which has a length of 4. To find the measure of this angle, we can use the inverse tangent function:
tan(theta) = opposite / adjacent = 3/4
[tex]theta = tan^{-1} (3/4)[/tex]
Using a calculator, we can find that:
theta ≈ 36.87 degrees
Therefore, the measure of the larger acute angle in the 3-4-5 right triangle is approximately 36.87 degrees.

The house is now
years old
Mark and Lynne have 28 years left on their mortgage. To figure out how old their house is right now, we need to divide the remaining years on the mortgage by 5.
This is because when the mortgage is paid off, their house will be 5 times as old. Therefore, 28 divided by 5 is equal to 5.6 years old. This means that the house is currently 5.6 years old. After 28 years, the house will be 33.6 years old.
Mark and Lynne have a mortgage on their house that still has 28 years remaining on it. To figure out the age of the house currently, we need to do a simple calculation. When the mortgage is paid off, their house will be 5 times as old as it is now. Therefore, if we divide the remaining years on the mortgage by 5, we will get the current age of the house. 28 divided by 5 is equal to 5.6 years old. This means that the house is currently 5.6 years old. In 28 years, when the mortgage is paid off, the house will be 33.6 years old.

What is Side-Angle-Side (SAS) criterion?
The Side-Angle-Side (SAS) criterion is a rule used in geometry to determine whether two triangles are congruent, which means they have the same size and shape. The SAS criterion states that if two sides and the angle between them in one triangle are equal to two corresponding sides and the angle between them in another triangle, then the two triangles are congruent. This means that all corresponding angles and sides of the two triangles are equal in length and measure.
To determine whether the two triangles are congruent, we can use the side-angle-side (SAS) congruence criterion. We can see that triangle PQR has sides PQ, QR, and RP, and angle QPR, while triangle STU has sides ST, TU, and US, and angle TSU. We can compare the corresponding sides and angles:
PQ is of length 4, and ST is of length 4.
QR is of length 1, and TU is of length 4.
RP is of length 2, and US is of length 2.
Angle QPR is a right angle, while angle TSU is an acute angle.
Therefore, the two triangles do not have the same corresponding sides and angles, and we cannot conclude that they are congruent.
The correct option is:
No; Two sides of triangle PQR and angle PQR are not the same measure as the corresponding sides and angle of triangle STU.

The percentage of observations less than 130 is 97.7%, and the number of observations less than 130 = 879
The question asks about the percentage and number of observations that are less than 130 in a data set that follows a bell-shaped distribution with a mean of 120 and a standard deviation of 5.
a. To find the percentage of observations that are less than 130, we can use the z-score formula:
z = (x - μ) / σ
where x is the value we are interested in, μ is the mean, and σ is the standard deviation.
Plugging in the given values, we get:
z = (130 - 120) / 5
z = 10 / 5
z = 2
Using a standard normal table or calculator, we can find that the probability of a z-score being less than 2 is approximately 0.9772. This means that approximately 97.7% of the observations are less than 130.
b. To find the number of observations that are less than 130, we can multiply the percentage by the total number of observations:
Number of observations = 0.9772 * 900
Number of observations = 879.48
Rounding to the nearest whole number, we get that approximately 879 observations are less than 130.

the birthday problem - there are 23 people in this class. what is the probability that at least 2 of the people in the class share the same birthday?
The probability that at least 2 of the people in the class share the same birthday is approximately 0.507 or 50.7%.
The probability that at least two people share the same birthday in a class of 23 people can be calculated using the formula for a complement of an event, which states that the probability of an event happening is 1 minus the probability of it not happening.
Therefore, let’s first calculate the probability that no two people share the same birthday in a class of 23 people.
There are 365 days in a year, and if we assume that all the days are equally likely to be birthdays, then the first person can choose any day, and the probability of the second person not having the same birthday is (364/365), and for the third person, it is (363/365), and so on for the other people.
Therefore, the probability of none of them sharing the same birthday is
(364/365) × (363/365) × … × (343/365) which is approximately 0.493.
The probability of at least two people sharing the same birthday is the complement of the probability that none of them share the same birthday.
Therefore, the probability of at least two people sharing the same birthday in a class of 23 people is
1 − 0.493 ⇒ 0.507.
Hence, there is a 50.7% chance that at least two people share the same birthday in a class of 23 people.

PLEASE HELP!!! Using technology, graph these functions and find the solution to the system.
f(x) = x²+x-4
g(x) = -2x2-2x+14
(-2.5, 5) and (1.5, 5)
(-4, 14)
(-3, 2) and (2, 2)
No solution: They do not intersect.
The solution of the functions given will be (-3, 2) and (2, 2) as we can see in graph.
What is the definition of a function?
In mathematics, a function is a rule that associates each element in one set, called the domain, with a unique element in another set, called the range. In other words, a function is a relation between two sets such that each element in the domain is paired with exactly one element in the range.
A function can be represented by an equation, a graph, a table, or a verbal description. The notation f(x) is often used to represent a function, where f is the name of the function and x is the input (or independent variable). The output (or dependent variable) is then given by f(x).
Now,
For functions f(x) = x²+x-4
g(x) = -2x²-2x+14
the graph will be made as shown in image
and their intersection points will be the solution of the given functions
Hence,
The solution of the functions given will be (-3, 2) and (2, 2) as shown in graph.
