amelia needs to buy some cat food at the nearest store 2 bags of cat food is 6.50. How much would it be if amelia bought 3 bags?
Answers
Answer:
$9.75
Step-by-step explanation:
We have all we need to solve for Bag #3.
2 bags equal $6.50.
We want 3 bags, not 4. So we need to divide the original cost by 1/2.
$6.50 divided by 1/2 is $3.25
Now we add an additional $3.25 to the original $6.50
Suppose we have two random variables X and Y . The one with a
higher coefficient of variation exhibits higher variability Is true, false or uncertain?
Answers
The statement that the one with a higher coefficient of variation exhibits higher variability is true.
How to explain thisThe coefficient of variation expresses the proportionate level of variability present in a random variable and can be determined by dividing the mean by the standard deviation.
If the coefficient of variation is higher, it means that the random variable shows more variation in relation to its mean.
To illustrate, suppose that the average height of a set of males is 6 feet with a standard deviation of 2 inches.
The variance ratio would result in a coefficient of variation of 0. 033 Suppose that a group of females has an average height of 5 feet with a standard deviation of 1 inch.
The women's coefficient of variation is calculated to be 0. 02 The variance of men's height in relation to their average height is indicated by their higher coefficient of variation.

The solution of the given linear equation when
1. there is no solution, is x=-7.
2.one solution, is x=0.
What is a linear equation, exactly?
A linear equation is an equation which can be written in the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept. The slope represents the rate of change of y with respect to x, and the y-intercept is the point where the line crosses the y-axis.
Now,
If there is no solution, then the equation must be contradictory, meaning that it simplifies to a statement that is always false.
5x - 2x + 7 - x = 0
2x + 7 = x
1. x = -7, which leads to a contradiction.
Therefore,
there is no solution to the equation when x=-7.
If there are infinitely many solutions, then the equation must be an identity, meaning that it simplifies to a statement that is always true.
5x - 2x + 7 - x = 2x + 7 - x
2x + 7 = 2x + 7
This simplifies to 0 = 0, which is true for all values of x.
2. Therefore, there are infinitely many solutions to the equation.
If there is one solution, then the equation must be consistent, meaning that it simplifies to a statement that is true for only one value of x.
5x - 2x + 7 - x = 3x + 7
2x + 7 = 3x + 7
-x = 0
x = 0
Therefore,
3. the equation has one solution, x = 0.

Clockwise from the top, the picture reads, x, 12 inches, 16 inches, x, Figure not drawn to scale.
Write an equation in standard form that can be used to find x , the width of the border.
Answers
Measuring to fit a cabinet opening includes a few extra steps to get the doors made in the right sizes for your remodel or renovation:
Measure the inside edges: When measuring the width, measure from left to right, starting with the inside edge of the left stile (vertical part of the face frame) to the inside edge of the right stile. When measuring height, measure from the inside edge of the bottom rail (horizontal part of the face frame) to the inside edge of the top rail. We build to 1/16 inch increments, so be precise.
Add space for door overlay: Cabinet doors for framed cabinets must be larger than the cabinet opening to look right and close properly. We refer to this as an "overlay". The industry standard for most cabinet doors is a 1/2 inch overlay around the cabinet door. To create a 1/2 inch door overlay on all four sides, add 1 inch to your total height, and 1 inch to your total width

What is a circle?A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).
In Geometry, a circle is considered to be a conic section which is formed by a plane intersecting a double-napped cone that is perpendicular to a fixed point (central axis) because it forms an angle of 90° with the central axis.
What is the inscribed angle theorem?The inscribed angle theorem states that the measure of an inscribed angle is one-half the measure of the intercepted arc in a circle. Thus, this is given by this mathematical expression:
m∠BDC = ½ × m∠BAC.
For this exercise, we would change the central angle, ∠CAB, so that the inscribed angle, ∠CDB can have the following data sets:

Answers
The solution is ,if it takes three people 4 hours to clean a warehouse , then 3 hours will it take 4 people to clean the warehouse.
Here, we have,
given that.
if it takes three people 4 hours to clean a warehouse
now, we have to find that how long will it take 4 people to clean the warehouse.
i.e. we have,
3 people take to clean = 4 hours
let, 4 people will take to do it x hours.
now, we have,
3 people take to clean = 4 hours
so, 1 people take to clean = 4*3 hours
so, 4 people take to clean = 4*3 / 4 hours
i.e. we get,
x = 4*3 / 4 hours
or, x = 12/4 hours
= 3 hours
Hence, if it takes three people 4 hours to clean a warehouse , then 3 hours will it take 4 people to clean the warehouse.

what is fraction ?A fraction can be used to symbolise a portion of a whole or a ratio of two quantities in mathematics. It has a horizontal strip separating the numerator (top number) from the denominator (bottom number). The numerator is the overall number of equally-sized parts that the whole is divided into, and the denominator is the number of those parts that are being taken into account. For instance, the fraction 3/4 denotes three of a whole that is made up of four equal portions. The numerator, 3, indicates that we are only taking into consideration three of the four equal portions that the denominator, 4, denotes. Depending on whether or not the numerator is less than or larger than, a fraction may be proper or improper.
given
Assume that the hamburger is cut into 1 complete piece.
He consumed 1/7 of the burger for lunch, making the remaining portion as follows:
1 - 1/7 = 6/7
He consumed 25% of the remaining sandwich at supper, which is:
(25/100) x (6/7) = 6/28 = 3/14
As a result, the amount of the meal he has not yet consumed is:
6/7 - 3/14 = (12/14) - (3/14) = 9/14

Answers
Answer:
The orthocentre of the given vertices ( 2 , -3.5)
Step-by-step explanation:
Step(i):-
The orthocentre is the intersecting point for all the altitudes of the triangle.
The point where the altitudes of a triangle meet is known as the orthocentre.
Given Points are K (3.-3), L (2,1), M (4,-3)
The Altitudes are perpendicular line from one side of the triangle to the opposite vertex
The altitudes are MN , KO , LP
step(ii):-
Slope of the line
\(KL = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{1-(-3)}{2-3} = -4\)
The slope of MN =
The perpendicular slope of KL
= \(\frac{-1}{m} = \frac{-1}{-4} = \frac{1}{4}\)
The equation of the altitude
\(y - y_{1} = m( x-x_{1} )\)
\(y - (-3) = \frac{1}{4} ( x-4 )\)
4y +12 = x -4
x - 4 y -16 = 0 ...(i)
Step(iii):-
Slope of the line
\(LM = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{-3-1}{4-2} = -2\)
The slope of KO =
The perpendicular slope of LM
= \(\frac{-1}{m} = \frac{-1}{-2} = \frac{1}{2}\)
The equation of the altitude
\(y - y_{1} = m( x-x_{1} )\)
The equation of the line passing through the point K ( 3,-3) and slope
m = 1/2
\(y - (-3) = \frac{1}{2} ( x-3 )\)
2y +6 = x -3
x - 2y -9 =0 ....(ii)
Solving equation (i) and (ii) , we get
subtracting equation (i) and (ii) , we get
x - 4y -16 -( x-2y-9) =0
- 2y -7 =0
-2y = 7
y = - 3.5
Substitute y = -3.5 in equation x -4y-16=0
x - 4( -3.5) - 16 =0
x +14-16 =0

What is dilation?In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
Next, we would have to dilate the coordinates of the preimage by using a scale factor of 3/5 centered at the origin as follows:

What is the volume of this triangular pyramid
Answers
Answer:
The right triangular pyramid volume is given by the formula V = 1 3 × B × h , where B is the area of the triangular base and h is the height (the distance from the apex to the base).
Step-by-step explanation:
Answer:
192 cubic feet
Step-by-step explanation:
The volume V of a triangular pyramid is given by the formula:
V = (1/3) * base area * height
where base area is the area of the triangular base.
In this case, the triangular base has a length of 8 ft and a width of 8 ft, so it is a square with area:
base area = length * width = 8 ft * 8 ft = 64 sq ft
Substituting the given values into the formula, we get:
V = (1/3) * 64 sq ft * 9 ft
V = 192 cubic feet.
Therefore, the volume of the triangular pyramid is 192 cubic feet.
