According to the given information, the one angle on the straight line inside a circle is 135 then the value of the x = 4 as both angles are supplementary angles.
What are supplementary angles?Supplementary angles are two angles whose sum is 180 degrees. In other words, if we add the measures of two supplementary angles, the result is always 180 degrees.
When two lines intersect, they form four angles at the intersection point. If two of these angles are supplementary, they are called adjacent supplementary angles. In this case, they share a common side and a common vertex, and their non-shared sides form a straight line.
For example, if angle A and angle B are adjacent angles, and angle A measures 120 degrees, then angle B must measure 60 degrees, since 120 + 60 = 180.
According to the given informationIf the two angles are on a straight line, then they are supplementary, meaning their sum is 180 degrees. Therefore, we can set up the equation:
135 + (11x + 1) = 180
Simplifying the left side, we get:
136 + 11x = 180
Subtracting 136 from both sides, we get:
11x = 44
Dividing both sides by 11, we get:
x = 4
Therefore, the value of x is 4.

Determine the perimeter of the right triangle shown.
right triangle with vertices at negative 5 comma 3, negative 5 comma negative 2, and 7 comma negative 2
The perimeter of the right triangle is 30 units.
What is perimeter?
In geometry, perimeter refers to the total length of the boundary of a two-dimensional shape, such as a polygon or a circle. It is the sum of the lengths of all the sides of the shape.
To find the perimeter of the right triangle, we need to determine the lengths of its sides first.
Using the distance formula, we can find the lengths of the three sides of the triangle:
Side 1: From (-5, 3) to (-5, -2)
[tex]Length = \sqrt{[(3 - (-2))^2 + (-5 - (-5))^2]} = \sqrt{[5^2]} = 5[/tex]
Side 2: From (-5, -2) to (7, -2)
[tex]Length = \sqrt{[(7 - (-5))^2 + (-2 - (-2))^2]} = \sqrt{[12^2]} = 12[/tex]
Side 3: From (7, -2) to (-5, 3)
[tex]Length = \sqrt{[(-5 - 7)^2 + (3 - (-2))^2]} = \sqrt{[144 + 25]} = \sqrt{[169]} = 13[/tex]
We know that the triangle is a right triangle because two of its sides (Side 2 and Side 3) form a straight line along the x-axis, and the third side (Side 1) is perpendicular to this line.
Therefore, Side 1 is the hypotenuse, and Sides 2 and 3 are the legs of the right triangle.
To find the perimeter, we add up the lengths of all three sides:
Perimeter = Side 1 + Side 2 + Side 3 = 5 + 12 + 13 = 30
Therefore, the perimeter of the right triangle is 30 units.

Myron's family is putting a pool in their backyard. He is so excited that he wants to figure out how
long it will take to fill the pool! He found the blueprints for the pool and recreated the sketches at
right, but he is not quite sure how to use them to find the volume of the pool.
What three-dimensional figures does Myron need to be able to find the volume of before he can
determine the volume of the pool?
To find the volume of an irregular 3D shape like Myron's pool, he needs to determine:
1. The length
2. The width
3. The depth
With those three measurements, he can plug them into the formula for volume of a rectangular prism:
Volume = Length x Width x Depth
So if the pool is:
Length = 20 ft
Width = 10 ft
Depth = 5 ft
Then the volume would be:
20 ft x 10 ft x 5 ft = 1000 cubic feet
Does this make sense? Let me know if Myron has any other questions!
You deposited $5,000 in your account earning 2.5 simple interest how long would it take for the balance of the account to earn $1,500 in interest?
To solve this problem, we can use the formula for simple interest:
I = P * r * t
where I is the interest earned, P is the principal amount (the initial deposit), r is the interest rate as a decimal, and t is the time in years.
We want to find how long it will take for the account balance to earn $1,500 in interest, so we can set up the equation:
$1,500 = $5,000 * 0.025 * t
where t is the time in years.
Simplifying this equation, we get:
t = $1,500 / ($5,000 * 0.025)
t = 12 years
Therefore, it will take 12 years for the balance of the account to earn $1,500 in interest
Scores on the GRE (graduate record examination) are normally distributed with a mean of 553 and a standard deviation of 112. Use the 68-95-99.7 rule to find

The percentages of people taking the test who scores between 421 and 645 is__%
The percentages of people taking the test who scores between 421 and 645 is: 68 %
How to use the empirical rule of statistics?The empirical rule, also referred to as the three-sigma rule or the 68-95-99.7 rule, is defined as a statistical rule which states that almost all observed data for a normal distribution will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).
We are given:
Sample mean: x' = 553
standard deviation; s = 112
Thus:
x' - ns = 421
x' + ns = 645
Where n is the number of standard deviations from the mean. Thus:
553 - 112s = 421
112s = 553 - 421
112s = 132
s = 132/112
s ≈ 1
So 1 standard deviation from the means indicates a percentage of 68%

x²+x-72=0 rewrite the equation by completing the square
The solution of the equation written by completing square is (x + 1/2)² = 289/4.
What is completing square?In algebra, the process of "completing the square" is used to transform a quadratic expression into a perfect square trinomial. Using this method, a constant term is either added or subtracted from the quadratic expression to produce a perfect square trinomial that may be factored as the square of a binomial. Solving quadratic equations, locating the vertex of a parabola, and simplifying formulas with square roots all involve the completion of the square.
The value of the equation x² + x = 72 can be written as a completer square by taking half of the coefficient of the x-term.
(1/2)² = 1/4
Add this to both sides of the equation:
x² + x + 1/4 = 72 + 1/4
Now, the LHS is:
(x + 1/2)² = 289/4
x = -1/2 ± (17/2)
Hence, the solution of the equation written by completing square is (x + 1/2)² = 289/4.

The height of point A is 0 feet. However, this is not the actual height of point A, as it is at the highest point on the Ferris Wheel, which is 185 feet as calculated previously.
How to solveThe height of point A on the Ferris Wheel can be calculated using the sine function, as it is the vertical component of the point's position. The center of the Ferris Wheel is 100 feet off the ground, and its radius is 85 feet.
Let's denote the height of point A as h_A, which is the vertical distance from the center of the Ferris Wheel to point A.
Since point A is at the 0 radian position, it is at the highest point on the Ferris Wheel. At this point, the height of point A is equal to the sum of the radius and the center's height:
h_A = radius + center's height
h_A = 85 + 100
h_A = 185 feet
So, the height of point A off the ground is 185 feet.
To estimate the value of h_A using the sine function, we can use the fact that at any given angle θ on the unit circle, the height of the point on the circle is given by the sine of that angle multiplied by the radius. In this case, since point A is at the highest point on the Ferris Wheel, we can use the sine of 0 radians (which is 0) to estimate the height of point A:
h_A = radius * sin(0)
h_A = 85 * 0
h_A = 0
So, using the sine function, we estimate that the height of point A is 0 feet. However, this is not the actual height of point A, as it is at the highest point on the Ferris Wheel, which is 185 feet as calculated previously.

Yes, this represents an exponential function.
What is exponential function ?
The exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function.
Because the growth rate is inversely correlated with the function's present value, this function is exponential. Regardless of how many cells were present the previous hour the number of cells is multiplied by the same factor of 4 every hour.
Therefore, One can estimate the number of cells for every hour x by evaluating the function at a specific value of x. The function f(x) = 4x implies exponential growth.
