The three sides are given 24, 30 and 18.
Explanation
To find the triangle is acute, obtuse or right triangle.
To determine whether the triangle is acute, right, or obtuse.add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.
A
If the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.
Now c.
[tex]\begin{gathered} 30^2=24^2+18^2 \\ 900=576+324 \\ 900=900 \end{gathered}[/tex]Answer
Hence the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.
The correct option is A.

The function 1 is,
[tex]y=\frac{1}{3}x[/tex]So rate of function is 1/3.
From the table function 2 it can be observed that the value of y is one third of x. The mathematical expression of function 2 is,
[tex]y=\frac{1}{3}x[/tex]So rate of function 2 is also 1/3.
Thus function 1 and function 2 have the same rate, 1/3.
Decide whether the random variable x is discrete or continuous. Explain your reasoning. Let x represent the time it takes to run a mile. Is the random variable x discrete or continuous?
The variable represents time. The time in which a person runs a mile will depend on the speed of that person, and that can take almost any value, thus, here the variable is continuous.
Is the variable discrete or continuous?First, when a variable is discrete and when it is continuous?
A variable is discrete if it only can take some selected values on a given interval, while a variable is continuous if it can take any value (or at least a dense set) of values in that interval.
For example, the numbers that one can roll on a dice form a discrete set, because the values can only be {1, 2, 3, 4, 5, 6}, just to given an example.
Now, in this case, the variable represents time. Time almost always is a continuous variable, in this case, the time is the time in which a person runs a mile. So that variable can take almost any value (depends on the speed of the person).
So we conclude that this is a continuous variable.

Answer:
Either of ...
reflection across the y-axis, and translation down 6reflection across the x-axis and translation down 4Step-by-step explanation:
You want the transformations that take f(x) = 3x+1 to g(x) = -3x-5.
TransformationThe x-term of the transformed function has a sign opposite that of the original function. That can be accomplished by either of (a) reflection across the y-axis (replaces x by -x), or by (b) reflection across the x-axis (replaces f(x) by -f(x)).
Either way, an additional translation is required. That translation can be either vertical or horizontal, and may be done either before or after the reflection.
Horizontal reflectionReflecting f(x) across the y-axis means it becomes ...
f(-x) = 3(-x) +1 = -3x +1
In order to make that into -3x-5, we must add -6 to the function value:
g(x) = f(-x) -6 = (3(-x)+1) -6 = -3x -5
F(x) will be taken to g(x) = -3x-5 by reflection across the y-axis and translation down 6 units.
Vertical reflectionReflecting f(x) across the x-axis means it becomes ...
-f(x) = -(3x +1) = -3x -1
In order to make that into -3x-5, we must add -4 to the function value:
g(x) = -f(x) -4 = -(3x +1) -4 = -3x -5
F(x) will be taken to g(x) = -3x-5 by reflection across the x-axis and translation down 4 units.
__
Additional comment
As noted above, the translation can be either horizontal or vertical. For example, translating the function 2 units to the right makes it f(x-2). Then reflection across the y-axis replaces x by -x, so we have ...
g(x) = f(-x-2) = 3(-x-2)+1 = -3x -6 +1 = -3x -5
To get g(x), we could translate right 2 units, then reflect across the y-axis.
We also note that point (-1, -2) is shared by f(x) and g(x), so reflection horizontally across the line x=-1, or vertically across the line y=-2 would also give the required transformation.

earn a minimum of $140. If a represents the number of hours tutoring and y
represents the number of hours landscaping, write and solve a system of inequalities
graphically and determine one possible solution.
The equations will be a+ y ≤ 13, since Micaela can't work more than 13 hours and also she needs to earn at least $140 each week, so other equation will be 13a + 10y ≥ 140.
What is inequalities?Inequality, a declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
a = number of hours spent tutoring
y = number of hours spent landscaping
Micaela can't work more than 13 hours, so a + y ≤ 13.
Also, she needs to earn at least $140 each week, so 13a + 10y ≥ 140.
Using intercepts, you may graph things in this format on paper. They must be transformed into slope-intercept form in order to be graphed on a standard graphing calculator.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.
What is an angle?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.
Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius. The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.

Answer:
$3.33 (rounded) per hour
Step-by-step explanation:
The sprinklers run 5 hours each day. The monthly (30 days) water bill is $500. How much does it cost to run the sprinklers for an hour? Round your answer to the nearest cent.
hours run per month = daily hours × days in month
hours run per month = 5 × 30
hours run per month = 150
if the total bill was $500 for 150 hours then:
$500 ÷ 150 = $3.33 (rounded) per hour.
