The value for the Inequality 13x ≤ 200 is x ≤ 15.384.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
13 times a number x is less than or equal to 200.
Now, Writing the Inequality Mathematically

Use the formula V = Bh to calculate the volume of a cylinder that has a diameter of 6 centimeters and a height of 8 centimeters. Express your answer in terms of pi.
The volume of the cylinder is 72π cubic centimeters.
What is volume?
Volume is a measure of the amount of space occupied by an object or a substance. It is typically measured in cubic units such as cubic meters, cubic centimeters, cubic feet, or cubic inches.
For solid objects, volume refers to the amount of space the object occupies in three-dimensional space.
The formula for the volume of a cylinder is:
V = Bh
where B is the area of the base of the cylinder, and h is the height of the cylinder.
In this problem, the cylinder has a diameter of 6 centimeters, which means the radius is 3 centimeters. The area of the base of the cylinder is therefore:
B = πr²
B = π(3 cm)²
B = 9π cm²
The height of the cylinder is given as 8 centimeters. Therefore, we can use the formula for the volume of a cylinder to find the volume V:
V = Bh
V = (9π cm²)(8 cm)
V = 72π cubic centimeters
Therefore, The volume of the cylinder is 72π cubic centimeters.

Step-by-step explanation:
The slashes through the lines indicate they're of the same length, which means this is an equilateral triangle. Therefore all three angles are 60 degrees.
The lines being parallel mean that angle x shares the same angle as the triangle in the bottom-right corner.
The parallel lines intersecting with the line segment that is consistent throughout the triangle makes the angle the same.
Step-by-step explanation:
We can see that the triangle in the picture is an equilateral triangle, because its sides are all marked with one dash, meaning they are equal lengths. We note that all the angles in an equilateral triangle are each 60°.
The little arrows on the top and bottom lines in the figure indicate that they are parallel, which means that the diagonal line between them creates a set of alternate angles (I've attached a pic of what alternate angles generally look like to make this clearer).
Alternate angles are equal, which means x is equal to the angle at the bottom right of the triangle, which is 60°.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (−2 ,− 9) and (−6,7). PLSLLSLS
The equation of the perpendicular bisector of the line segment joining (-2, -9) and (-6, 7) is y = (-1/4)x - 2
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The midpoint of the line segment joining (-2, -9) and (-6, 7) can be found using the midpoint formula:
Midpoint = ( (x₁+x₁)/2 , (y₁+y₁)/2 )
Midpoint = ( (-2-6)/2 , (-9+7)/2 )
Midpoint = (-4,-1)
Next, we need to find the slope of the line joining the two points (-2, -9) and (-6, 7). We can do this using the slope formula:
Slope = (y₂ - y₁) / (x₂ - x₁)
Slope = (7 - (-9)) / (-6 - (-2))
Slope = 4
The slope of the line perpendicular to the line segment is the negative reciprocal of the slope of the line joining the two points. So the slope of the perpendicular line is -1/4.
Using the point-slope form of a line, the equation of the perpendicular bisector can be written as:
y - y₁ = m(x - x₁), where (x₁, y₁) is the midpoint and m is the slope of the line.
Plugging in the values we found, we get:
y - (-1) = (-1/4)(x - (-4))
y + 1 = (-1/4)(x + 4)
y + 1 = (-1/4)x - 1
y = (-1/4)x - 2
Therefore, the equation of the perpendicular bisector of the line segment joining (-2, -9) and (-6, 7) is y = (-1/4)x - 2.

The answer I get is -3x^9 +2x^8 -8 over x^4
What does it simplify to? Use positive exponents only
Answer:
Step-by-step explanation:
To simplify the expression, we need to divide -3x^9 + 2x^8 - 8 by x^4.
The procedure is as follows:
Divide -3x^9 by x^4: -3x^9 / x^4 = -3x^5
Divide 2x^8 by x^4: 2x^8 / x^4 = 2x^4
Divide -8 by x^4: -8 / x^4 = -8x^-4
Combine the results from steps 1-3: -3x^5 + 2x^4 - 8x^-4
Note that the exponent of x in each term is either positive or zero. We can't simplify the expression further since we can't simplify the exponents any more.

Lim 3√x-1/x-1. as x tends to 1
Answer: To find the limit of the expression 3√x-1/x-1 as x approaches 1, we can use L'Hopital's Rule. L'Hopital's Rule is a method for finding the limit of indeterminate forms, such as 0/0 or ∞/∞, by taking the derivative of the numerator and denominator.
In this case, the expression is of the form 0/0, so we can use L'Hopital's Rule:
lim 3√x-1/x-1 = lim (3/2)((x-1)^(1/2)) / 1 = 3/2
So the limit of the expression 3√x-1/x-1 as x approaches 1 is equal to 3/2.

What is Independent and Dependent Variable?We anticipate that independent variables will have an impact on dependent variables. What occurs as a result of the independent variable is referred to as a dependent variable.
Given:
We can see from Option A that the opposite may not be true, as an increase in the risk of lung cancer may not always be accompanied by an increase in the number of cigarettes smoked each day.
Now, second it is clear that the opposite may not be true because an infant's age may not necessarily increase along with his or her height.
Now, third also acknowledges that a rise in traffic is not always accompanied by an increase in pollution in a city.
Fourth, a rise in water density does not always imply an increase in the amount of salt present in the water.
