We can conclude that the supplement angle of 89° will be 91°.
What do we mean by supplement angles?Angles that add up to 180 degrees are referred to as supplementary angles.
For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
The sum of complementary angles is 90 degrees.
Two angles are complementary if their sum equals 90 degrees, and supplementary if their sum equals 180 degrees.
So, we have an angle of 89°.
We know that the supplement angle is an angle of measure 180°.
Now, the supplement angle of 89° will be as follows:
180 - 89
91°
Therefore, we can conclude that the supplement angle of 89° will be 91°.

How many children and how many adults swam at the public pool that day?
Using substitution method to solve the system of linear equation, the number of children is 90 and adults is 93.
What is System of Linear EquationIn mathematics, a system of linear equations is the collection of two or more linear equations that share the same variables. The maximum power of the variable in the linear equations in this situation is 1, making them first-order equations. A linear equation may have one, two, or three variables. We can therefore create linear equations with n variables.
To solve this problem, we have to define our variables and then write the equations.
Let;
x = childreny = adultx + y = 183 ...eq(i)
1.75x + 2.5y = 390 ...eq(ii)
solving both equations
From equation (i)
x + y = 183
x = 183 - y ...eq(iii)
Put equation (iii) into equation (ii)

The given linear relationship slope of the line is D) 6.
What is slope?
An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). The ratio of how much y grows as x grows by a certain amount is known as the slope of a line. A line's slope, or the amount by which y rises as x rises, indicates how steep a line is. The slope is constant (the same) along the line.
Here from given tables lets take any two points to find slope, then
[tex](x_1,y_1)=(0,-6) and (x_2,y_2)=(1,0)[/tex]
Now using slope formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] then
=> m = [tex]\frac{0-(-6)}{1-0}[/tex]
=> m =[tex]\frac{6}{1}[/tex]

according to money magazine, maryland had the highest mean annual household income of any state in at (time website). assume that annual household income in maryland follows a normal distribution with a mean of and standard deviation of .
The probability of getting a household income of $75,000 in Maryland is 0.3989.
The normal distribution formula is given by:
P(x) = 1/√(2πσ^2) * e^[-(x-μ)^2 / (2σ^2)]
Where,
P(x) - Probability of getting a household income of x
μ - Mean annual household income in Maryland
σ - Standard deviation of annual household income in Maryland
Assuming that the mean annual household income in Maryland is $75,000 and the standard deviation is $10,000, the probability of getting a household income of $75,000 can be calculated using the formula given above.
P(75000) = 1/√(2π10000^2) * e^[-(75000-75000)^2 / (2*10000^2)]

Answer: (0,10) and (3,1)
Step-by-step explanation:
Before I solve the system, I am going to rewrite it to make it easier for me to understand it.
[tex]y=(x-3)^2+1\\y=-3x+10[/tex]
Notice that f(x) and g(x) have been changed into y. The reason is because f(x) and g(x) are the same and stand for y, but we only use f and g to distinguish between the 2 equations. We can use equal values to solve.
[tex](x-3)^2+1=-3x+10[/tex] [exponent]
[tex]x^2-6x+9+1=-3x+10[/tex] [add both sides by 3x]
[tex]x^2-3x+10=10[/tex] [subtract both sides by 10]
[tex]x^2-3x=0[/tex] [factor]
[tex]x(x-3)=0[/tex]
Notice that x=0 and x-3=0. This means the solutions are x=0 and x=3.

2051/
2051/2 miles,The plane is travelling in a different direction from its original position, and the distance from the original position can be calculated by using the Law of Cosines.
How far is the plane from its original position?The plane's displacement from its original position can be calculated by finding the magnitude of the vector sum of the two displacements.The first displacement can be calculated using the magnitude of the vector, the bearing, and the formula for the magnitude of a vector in polar coordinates. The magnitude of the vector is equal to the distance traveled (160 miles) multiplied by the cosine of the bearing (327°). Therefore, the magnitude of the first displacement is 149.9 miles.The second displacement can be calculated in the same manner. The magnitude of the vector is equal to the distance traveled (205 miles) multiplied by the cosine of the bearing (311°). Therefore, the magnitude of the second displacement is 176.7 miles.The vector sum of the two displacements can be found by adding their respective x-components and y-components. The x-component of the first displacement is negative 149.9 miles, and the y-component is 131.8 miles. The x-component of the second displacement is negative 176.7 miles, and the y-component is 114.2 miles. The x-component of the vector sum is −326.6 miles, and the y-component is 246 miles.This problem is an example of vector addition. Vector addition is a mathematical process used to calculate the resultant displacement of two or more vector quantities. It is the process of combining two or more vectors to produce a vector that points in the same direction as the total of the individual vectors. In this case, we can use vector addition to find the distance from the plane's original position.

The slope of a line is a number that describes the steepness of a line and the direction it is heading. It is also known as the "rise over run" or the "rate of change" of a line. The slope of a line is typically represented by the letter "m" and is found using the formula:
slope = (y2 - y1) / (x2 - x1)
To find the slope of a line, you need two points on the line (x1, y1) and (x2, y2) and substitute their coordinates into the slope formula.
To find the slope of a line, we use the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, we have two points: (0, 2) and (1, -1). To find the slope between these two points, we can substitute their coordinates into the slope formula:
