Can the three angles 25 65 and 90 create one unique triangle
Answer:
Yes, it can. Triangles [in order for them to be one] must equal 180. If you add all of these angles together, since a triangle only has three angles anyway, it equals to 180, so you know it's a triangle.

340 students went to the first school dance, the last school dance 306 students attended. What is the percent of change between the two dances?
(Please help
Answer:
10.59%
Step-by-step explanation:
percentage of change is given by
{(old number - new number)/old number} * 100
_________________________
given
no. of student went to the first school dance = 340
no. of student went to the last school dance = 306
Percentage of change between two dance
= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100
= (340 - 306)/340 *100
= (36/340 )*100 = 10.59%
The percent of change between the two dances 10.59%.
50 POINTS! Carol is designing an artistic picture frame, which she wants to sell online. The picture frame will be square, but will come in several different sizes. She plans to place decorative stones around the outside of the picture frame. Carol’s first step was creating this prototype frame. (The first picture attached) You will be helping Carol form expressions that will tell her the number of stones she’ll need to order for each frame.
Part A:
How many stones make up the perimeter of the prototype picture frame? Perimeter is usually calculated by adding the length of each side of a shape. In the prototype, there are four stones per side. If we try to find the total number of stones in the frame by adding the number of stones per side, we’ll get an incorrect total. Why?
Part B:
Suppose that s equals the number of stones on one side of the picture frame. Write an expression that would give the number of stones in the top and bottom sides together.
Part C:
Write an expression in terms of s that represents the remaining stones. (The second attached picture) Write an expression in terms of s that represents the remaining stones.
Part D:
Now combine the two expressions you wrote in parts b and c by adding them together. What does the expression formed by this operation represent?
Answer: 12 stones
Step-by-step explanation:

Given is Lisa who is decorating outside edge of a square picture frame. She needs to know the side length of the frame. The area of the frame is [m] square inches.
It is given that the the area of the square is [m] square inches.
Assume that the length of the side is [x] inches.
x² = m
x = ±√m
Side cannot be negative.
Therefore, the side of the length will be - x = √m
Therefore, the side of the length will be x = √m square inches.

Jody flips a fair coin three times and each time it lands on heads. Jody believes he can calculate the probability of this occurring by adding the probability of getting a head on each individual flip. Explain why this is incorrect.
Answer:
When you have multiple events (here each flip of the coin is a individual event) the probability of all the events (or the joint probability) is equal to the product of the probabilities of each event.
For example, with a fair coin the probability of getting heads is 0.50
If you get heads 3 times, and you add the probabilities you get:
0-50*3 = 1.50
this has no sense, because the probability must be a number between 0 and 1.
The actual probability is:
P = 0.50*050*0.50 = 0.125
Determine the probability of each event flipping a coin and getting heads
ANSWER ASAP
Answer:
A coin has 1 head and 1 tail.
=> Probability of flipping a coin and getting head: 1/2

Question 29 A football coach walks 12 meters westward, then 16 meters eastward, then 22 meters westward, and finally 6 meters eastward. For this motion, what is the distance moved? What is the magnitude and direction of the displacement?
Answer: 56m ; 12m
Step-by-step explanation:
A football coach walks 12 meters westward, 16 meters eastward, 22 meters westward, and then 6 meters eastward. The total distance moved will be: 12m + 16m + 22m + 6m = 56 metres.
The displacement will be:
12i + 16i - 22i + 6i
= 34i - 22i
= 12m west
Answer:
Distance moved is 56 metersThe magnitude and direction of the displacement is 12 meters eastwardStep-by-step explanation:
Distance is scalar quantity and as such it has only magnitude and no direction.
The distance moved by the coach is calculated as;
distance = 12 meters + 16 meters + 22 meters + 6 meters
distance = 56 meters
Again, we determine the magnitude and direction of the displacement.
Displacement is a vector quantity and as such it has both magnitude and direction.
let westward represent positive direction, and
eastward represent negative direction
Displacement = 12 meters westward - 16 meters eastward + 22 meters westward - 6 meters eastward
Displacement = 12 meters eastward

In a class 27 of students, 12 have a cat and 11 have a dog. There are 5 students who have a cat and a dog. What is the probability that a student has a dog given that they have a cat?
Answer:
41.67% probability that a student has a dog given that they have a cat
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: having a cat.
Event B: having a dog.
12 of 27 students have a cat:
This means that [tex]P(A) = \frac{12}{27}[/tex]
5 students who have a cat and a dog.
This means that [tex]P(A \cap B) = \frac{5}{27}[/tex]
What is the probability that a student has a dog given that they have a cat?
[tex]P(B|A) = \frac{\frac{5}{27}}{\frac{12}{27}} = \frac{5}{12} = 0.4167[/tex]

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
The answer could be 0 or 1 out of 4, because choosing a card at first and not putting it back, then picking a second card at random, it would likely be one in zero attempts to pick 3 again but otherwise that it could be 1 out of 4 because it could be possible picking 3 at the first try.
Can someone pls help me
Answer:
No.
Step-by-step explanation:
For figures to be similar, they must have proportional sides.
In other words, we can take a number and use it to scale all the sides.
The small rectangle has a 5 on the bottom side, while the big rectangle has a 15 on the bottom side. The scale factor is 3.
The small rectangle has a 3 on the right side, while the big rectangle has a 6 on the right side. The scale factor is 2.
As the scale factors are not equivalent, the figures are not similar.
PLEASE HELP which equation in the word bank can solve for x ?
Answer:
x + 10 = 24
Step-by-step explanation:
In the figure attached,
There are two external points A and B.
Fro point A two tangents AD and AE have been drawn and From point B tangents BE and BC have been drawn.
Since AD = 10 units,
Therefore, AE = 10 units
(Since tangents drawn from a point to a circle are same in measure, therefore, AD = AE)
Therefore,
BE = AB - AE
Since BE = BC
So BC = AB - AE
x = 24 - 10
x + 10 = 24
Therefore, (x + 10) = 24 will be the equation to be used to solve for x.
A building casts a shadow 20 meters long if the angle from the tip of the shadow to the highest point of the building is 69 degrees what is the height of the building?
Answer:
52.1m
Step-by-step explanation:
Please see attachment for explanatory diagram.
From the diagram:
Opposite = H
Adjacent = 20m
Angle θ = 69°
The height, H of the building can be obtained as follow:
Tan θ = Opp /Adj
Tan 69 = H/20
Cross multiply
H = 20 x Tan 69
H = 52.1m
Therefore, the height of the building is 52.1m
US music is popular in Europe, and Japanese music is popular among many people in the US. This kind of artistic and
entertainment connection is an example of a(n)
connection
A.
cultural
Beconomic
Cindustrial
D. political
Answer:
The correct answer is - A. cultural.
Step-by-step explanation:
The exchange of music, thus creating an artistic and entertainment connection between the people of different countries, regions, or continents is a nice example of cultural connection.
The music is part of the culture of the people, and all the people from every part of the world have their own specific type of music that complements their culture.
With the globalization process, people have been able to see and hear things from all around the world, thus managing to hear the music of all pats of the world. The Japanese and Korean music have experienced a real ''boom'' in popularity in the western world, as lot of people find it interesting, and the American music also reached new countries where it became the most popular, like in Europe for example.
MARK ME BRAINLIEST PLEASE!!! :) HOPE IT HELPS
Answer:
A
Step-by-step explanation for why it's A:
The earth has become increasingly interconnected over recent times which has resulted in increased connection as well as cultural exchange amongst individuals.
This has allowed people to have access to new cultures,beliefs and ideas that were otherwise unavailable in their place of inhabitance.
Hence, Japanese music has become a lot more prevalent in the western world than it was say 60 years ago in a similar way American music has become more prevalent in Europe.
Software such as the internet have rapidly sped up globalisation and have resulted in remote accesibility to platforms such as social media that have made this cultural exchange boom in recent times possible.
Why it isn't the other options:
It could not be (b) as no forms of trading of commodities or other financial instruments are exchanged during the sharing of musical culture.
It could not be (c) as the spread of foreign culture within an area does not affect the manufacturing of goods and how they are sold between the involved countries.
It could not be (d) as certain procedures relating to the governance of a country( for instance in America)as well as political ideologies did not flourish( in a country say Japan) due to foreign musical acquisition.
