the middle of the triangle's circle. It is the intersection of the "perpendicular bisectors," or lines that are perpendicular to the middle of each side.

Triangle ABC's circumcenter is the point at which any two perpendicular bisectors of any two sides of the triangle come together.

The perpendicular bisector of sides B(3,0) and C(3,2) has the equation is y=1.

Because AB's slope is unknown and its midpoint is at 3,1. The slope of the perpendicular bisector is zero. Such a line has the equation y=y1.

Additionally, x=1.5 is the equation for the perpendicular bisector of A(0,0) and B(3,0). The explanation is because AB has a zero slope and a midway of (1.5,0). The slope of the perpendicular bisector will be ill-defined. x=x1 is the equation for such a line.

Answer: C= 40.25 - 0.05x

Step-by-step explanation:

C is the credit left

We know that the original is 40.25, so we put it as the beginning number.

Each minute costs $0.05x

where x is each minute

, so the equation is C= 40.25 - 0.05x

Club members spent 13 of the beginning balance to attend their first tournament so, the Chess Club spent $77 on their second tournament.

To calculate the balance of a sum of money, you need to know the initial amount of money and any additions or subtractions that have been made to it.

For example, if you start with $100 and then receive an additional $50, your balance would be $100 + $50 = $150. If you then spend $25, your balance would be $150 - $25 = $125.

To determine how much money the Chess Club spent on their second tournament, we need to first calculate the remaining balance after the first tournament. The Chess Club spent 13 of the beginning balance of $321, so the remaining balance is $321 - $13 = $308.

Next, we need to calculate 25% of the remaining balance. 25% of $308 is (25/100) * $308 = $77.

Thus, the Chess Club spent $77 on their second tournament.

Answer:

the length of RB is 18 cm.

Step-by-step explanation:

In △QRS, since point A is between points Q and R, and point B is between points R and S, we have that QR > QA > 0 and RS > RB > 0. Additionally, since AB∥QS, we know that the segment AB is parallel to the segment QS.

We can use this information to set up an equation to solve for RB. Since AB∥QS and QA = 23 cm, we have that QR = RB + 23. We can substitute this expression into the equation QR = 41 cm to get:

RB + 23 = 41

Solving this equation for RB, we get:

RB = 41 - 23

Therefore, the length of RB is 18 cm.

Hope this helps

21 miles per hour is the speed of boat still in water and 9 miles per hour is the speed of current.

Downstream - A boat is said to be moving downstream if it is moving in the same direction as the stream.

Upstream - A boat is said to be moving upstream if it is moving downstream of the stream. The term "upstream speed" in this context refers to the boat's net speed.

13) Given that, a boat traveled 280 miles downstream and back.

Time taken by boat in downstream is 7 hours and in upstream is 14 hours.

Let the speed of a boat be x miles per hour and the speed of a current be y miles per hour.

So, the total speed in downstream is x+y miles per hour and the total speed in upstream is x-y miles per hour.

We know that, Distance = Speed × Time

Now, 280=(x+y)×7

⇒ x+y=40 ------(I)

Here, 280=(x-y)×14

⇒ x-y=20 ------(II)

Add equation (I) and (II), we get

x+y+x-y=40+20

⇒ 2x=60

⇒ x=30 miles per hour

So, x+y=40

⇒ y=10 miles per hour

14) Given that, a boat traveled 252 miles downstream and back.

Time taken by boat in downstream is 12 hours and in upstream is 84 hours.

Let the speed of a boat be p miles per hour and the speed of a current be q miles per hour.

So, the total speed in downstream is p+q miles per hour and the total speed in upstream is p-q miles per hour.

We know that, Distance = Speed × Time

Now, 252=(p+q)×12

⇒ x+y=21 ------(I)

Here, 252=(p-q)×84

⇒ p-q=3 ------(II)

Add equation (I) and (II), we get

p+q+p-q=21+3

⇒ 2p=24

⇒ p=12 miles per hour

So, p+q=21

⇒ q=9 miles per hour

Therefore, the speed of boat still in water is 21 miles per hour and the speed of current is 9 miles per hour.

The die was rolled 7 times in there 60 times if it is landed on one-11 times, two-9 times, four-12 times, five-12 times, and six - 8 times.

Probabilities are mathematical explanations of the probability of an event occurring or of a proposition being true. The probability of an event is expressed as a number between 0 and 1, where 0 often indicates impossibility and 1 generally indicates certainty.

Given,

Number of times a die rolled=60

And also given that it landed on,

One --- 11 times

Converting the percentage to degree in the pie chart, angle PQ and UPT are 162° and 25.2° respectively

This is a statistical tool used to represent data in a chart. It is often represented using angles or percentage.

To find the value of the respectively angles, we have to convert the values from percentage to degree.

The formula to do this is given as

Percentage = angle * (100 / 360)

A)

Angle PQ = ?

Substituting the values;

45 = angle * (100 / 360)

45 = angle * (5/18)

angle = 45 / (5/18)

angle = 162°

B) Angle UPT = ?

Answer: 12/25

Step-by-step explanation:  3/25 × 4 is equaled to 3/25 × 4/1.

So first  we take 3 and 4 and multiply them to make 12.  

Then we take 25 and multiply it by 1 which would equal to 25.

Now we have 12/25 which cannot be simplified.

The expression 17n+11 represents the perimeter of a triangle, which is the sum of the lengths of the three sides of the triangle. Therefore, we can use this expression to determine the length of the third side of the triangle.

Since the perimeter of the triangle is equal to 17n+11, we know that the sum of the lengths of the three sides is equal to 17n+11. We can write this as:

a + b + c = 17n+11

where a, b, and c are the lengths of the three sides of the triangle.

To determine the length of the third side, we need to know the lengths of the other two sides. However, since the question does not provide this information, we cannot determine the length of the third side with certainty. In general, there are many different triangles that could have a perimeter of 17n+11, and the length of the third side could vary depending on the specific lengths of the other two sides.

Without additional information about the lengths of the other two sides, it is not possible to determine the length of the third side of the triangle.

If x² /y³ = 1 and x^4/2y³ = -1,  the value of the sum of x and y would be y^(3/2).

The fundamental procedures for altering and combining mathematical objects, such as integers and functions, are known as operations in mathematics. These operations, which are used to carry out mathematical computations on numbers, generally include sum, subtraction, multiplication, and division. Operations may also be applied to other types of mathematical objects, like as vectors, matrices, and sets, to execute more sophisticated operations such as vector addition, matrix multiplication, and set intersection. The outcome of an operation is referred to as an operand, and the procedures for combining operands are referred to as the operation's laws. A basic idea in mathematics, operations are applied in many different areas of science and math.

How to solve?

If x² /y³ = 1, then x² = y³

If x^4/2y³ = -1, then x^4 = -2y³

The sum of x and y is x + y = (x²)^1/2 + (y³)^1/3 = y^(3/2) + y

x + y = (x^4)^1/4 + (y³)^1/3 = (-2y³)^1/4 + y^(3/2) = -y + y^(3/2)

x + y = 0 + y^(3/2) = y^(3/2)

Inequalities are created through the connection of two expressions. It should be noted that the expressions in inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥  <  >   ≤.

An inequality is created when two or more algebraic expressions are compared using the symbols. They represent mathematical expressions where neither side is equal.

p ≠ q means that p is not equal to q

p < q means that p is less than q

p > q means that p is greater than q

p ≤ q means that p is less than or equal to q
