What are the ways to prove two triangles are similar?
Using the SAS(Side-Angle-Side) Theorem, ASA(Angle-Side-Angle) Theorem, SSS(Side-Side-Side) Theorem and AA(Angle-Angle) Theorem we can easily prove that two triangles are similar.
When the sides and angles of two triangles match, the triangles are said to be congruent. When the angles of two triangles match, the triangles are said to be similar. Thus, two triangles can be superimposed side to side and angle to angle.
Hence, when the sides and angles of two triangles match that triangle is congruent and When the angles of two triangles match that triangle is similar.

Leyla and her sister Maryam are excited to begin saving for a new bike they can share. Their aunt said that if they saved up enough money, she would split the cost with them and pay for half. The new bike will cost $110 total.
The girls concluded that they would have just enough if they saved the money from 2 days’ worth of Leyla’s paper route and 3 days’ worth of Maryam’s dog walking job. Maryam has to work a little more because her dog walking job pays $5 less than Leyla’s paper route. How much do the paper route and dog walking jobs each earn per day?
Answer:
paper route: $14 per daydog walking: $9 per dayStep-by-step explanation:
You want to know the pay for a paper route and dog walking if 2 days' paper route pay and 3 days' dog walking pay will total half of $110, while dog walking pays $5 less than the paper route.
SetupLet p represent the pay for a day's pay for the paper route. Then (p-5) is the day's pay for dog walking. The total pay is ...
2p +3(p -5) = 110/2
SolutionSimplifying the equation, we have ...
5p -15 = 55
p -3 = 11 . . . . . . . . divide by 5
p = 14 . . . . . . . . add 3
p -5 = 14 -5 = 9 . . . . . pay for dog walking
The paper route and dog walking pay 14 and 9 dollars per day, respectively.

We could write two equations, and solve by substitution. We would get the same single equation by doing that. In this solution method, it works well to let the variable represent the largest contributor (highest pay).
We could also solve the two equations by any of several other methods. The attached graph shows the solution by graphing.
For each graph below, state whether it represents a function. Graph 1 Graph 2 Graph 3 24 . 864 7 21 6 & -2 4- -6- Function? Yes O No Graph 4 Yes ONo Graph 5 Yes O No Graph 6 60 Function? Yes O No Yes ONo Yes O No
Using the vertical line test, there are only two graphs that represent functions (graph function): graph, 1 and graph 6.
A graph function is a graph that represents a function on a coordinate plane, which means that every point on the graph fulfills the function equation. In a graph function, an x corresponds to only one y.
If we want to know whether a graph represents a function or not, we can perform a vertical line test. In this test, we can drag a vertical line from left to right on the graph. If the vertical line intersects with the graph at one point at a time, then it's a function.
Otherwise, if the vertical line intersects with the graph at two or more points at a time, then it's not a function. It could happen when an x value gives two or more y values (1 input results in multiple outputs), which means the graph is not a function.
Now we take a look at the given picture.
Graph 1: when we drag a vertical line from left to right on the graph, it intersects with the graph at one point at a time. So yes, the graph represents a function.
Graph 2: when we drag a vertical line from left to right on the graph, it intersects with the graph at two points. So no, the graph doesn't represent a function.
Graph 3: when we drag a vertical line from left to right on the graph, it intersects with the graph at one point at first. But later on, it crosses two points in the graph. So no, the graph doesn't represent a function.
Graph 4: when we drag a vertical line from left to right on the graph, it intersects with the graph at two points. So no, the graph doesn't represent a function.
Graph 5: when we drag a vertical line from left to right on the graph, it also intersects with the graph at two points. So no, the graph doesn't represent a function.
Graph 6: when we drag a vertical line from left to right on the graph, it intersects with the graph at one point at a time. So yes, the graph represents a function.
So there are only two graphs that represent functions: graph, 1 and graph 6 since the other graphs fail the vertical line test.

The plane intersects the paraboloid in an ellipse. Find the points on this ellipse that are nearest to and farthest from the origin. Point farthest away occurs at.
The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.
To find the points on the ellipse that are nearest to and farthest from the origin, we need to consider the equation of the paraboloid and the equation of the ellipse.
The equation of a paraboloid is given by:
[tex]z = ax^2 + by^2 + c[/tex]
where a, b, and c are constants.
The equation of an ellipse is given by:
[tex](\frac{x}{a})^2 + (\frac{y}{b})^2 = 1[/tex]
where a and b are the semi-major and semi-minor axes of the ellipse, respectively.
If the plane intersects the paraboloid in an ellipse, then the equations of the paraboloid and the ellipse must be equal at the points of intersection. Therefore, we can set the equation of the paraboloid equal to the equation of the ellipse and solve for the x and y values.
[tex]z = ax^2 + by^2 + c[/tex]
[tex](\frac{x}{a})^2 + (\frac{y}{b})^2 = 1[/tex]
Substituting the equation of the paraboloid into the equation of the ellipse, we get:
[tex](\frac{x}{a})^2 + (\frac{y}{b})^2+c = 1[/tex]
We can then solve this equation for the values of x and y that correspond to the points on the ellipse that are nearest to and farthest from the origin.
The point farthest away from the origin occurs at the point on the ellipse that is farthest from the center, which is called the "foci" of the ellipse. The distance from the center of the ellipse to the foci is called the "eccentricity" of the ellipse. The eccentricity is denoted by the letter "e" and is calculated using the following formula:
[tex]e = \frac{\sqrt{(a^2 - b^2)}}{a}[/tex]
where a and b are the semi-major and semi-minor axes of the ellipse, respectively.
Therefore, to find the point on the ellipse that is farthest from the origin, we need to calculate the eccentricity of the ellipse and then use this value to determine the location of the foci. The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.

Answer:
4700 workers
Step-by-step explanation:
We know that 60% of the worker are men
1880 people work for the company who aren't men
100% - 60% = 40%
40% of workers = 1880
40% = 0.4
If 0.4 = 1880
100% of the workers x
100% = 1
We have equations
0.4 = 1880
1 = x
Cross multiply
0.4x = 1880
Divided both sides by 0.4

40x = 60(1 880)
40x = 112 800
x = 2 820
First solution said that there are 2 820 men and 1 880 womenthere are 4 700 workers all in allSECOND SOLUTION: base rate percentagePercentage = Rate / Base
= 1 880 / (1 - 0.60) (1-0.60 to find out the percent of not men)
= 1 880 / 0.40
= 4 700
There are total of 4 700 workers because there are 1 880 women meaning 4 700 - 1 880 = 2 820There are 2 820 womenCHECKING:Women: 4 700 * 0.4 = 1 880 (this statement is true)
Men: 4 700 * 0.6 = 2 820 (therefore, it is too)
Step-by-step explanation:
heart and star pls <3 brainliest will be appreciated <3(っ◔◡◔)っ -{ elyna s }-The amount P of pollution varies directly with the population N of people. City A has a population of 468,000 and produces 260,000 tons of pollutants. Find how many tons of pollution we should expect City B to produce, if we know that its population is 350,000.
Answer: you should expect 218,750 tons of pollutants from City B.
Step-by-step explanation:
When two variables vary "directly", it means that they fit into the equation y=mx, where y varies directly with x, with the multiplier m to be determined by the information you are given.
For this problem, P (pollutants) varies directly with N (people) so the equation is P=mN for their relation.
You are given that City A has P = 260,000 tons of pollutants and N = 416,000 people. Plug these into the equation above (P=mN) and you get 260,000=(m)(416,000). If we divide each side by 416,000, you get that m=0.625. So now you have the multiplier for your equation: P=(0.625)N.
Use the complete equation now to find out how many P (pollutants) City B will produce.
P=(0.625)N
P=(0.625)(350,000) [[350,000 was the given "N" or amount of people in City B]]
P=218,750 tons of pollutants
What theorems apply to equilateral triangles?
Theorems apply for equilateral triangles are theorem 1 and 2, In theorem 1 each angle of an equilateral triangle is the same and measures 60 degrees each while in theorem 2 a triangle is said to be equilateral if and only if it is equiangular.

Zach scores a ringer 40\%40%40, percent of the time that he throws a horseshoe. Let rrr be the number of throws it takes zach to score his first ringer in a game. Assume the results of each throw are independent. Find the probability that it takes zach 555 or more throws to score his first ringer.
There is about a 7.3% probability that it will take Zach 555 or more throws to score his first ringer.
To solve this problem, we can use a geometric distribution, which models the number of trials it takes to get a success in a series of independent Bernoulli trials (trials with two outcomes: success or failure) with a fixed probability of success.
In this case, the probability of success is 40% (the probability of scoring a ringer), and the probability of failure is 60% (the probability of not scoring a ringer). We can use the formula for the probability mass function of a geometric distribution to calculate the probability that it takes Zach 555 or more throws to score his first ringer:
P(X ≥ 555) = 1 - P(X < 555)
= 1 - (P(X = 1) + P(X = 2) + ... + P(X = 554))
= 1 - (0.4 + (0.4 * 0.6) + (0.4 * 0.6^2) + ... + (0.4 * 0.6^554))
To calculate this probability, we can use a computer to sum up the series, or we can use a calculator with a geometric distribution function. Using a calculator, we get P(X ≥ 555) ≈ 0.073, or about 7.3%.
This means that there is about a 7.3% probability that it will take Zach 555 or more throws to score his first ringer.
