How to Split 2 loaves of bread equally between 7 people

The quadrilateral you're describing is a Kite. A kite is a quadrilateral with two pairs of consecutive congruent sides, and its diagonals meet at a right angle.

The length of the rectangle is 10.5 units.

What is perimeter?

Perimeter is the distance of a two-dimensional shape. It is equal to the sum of the lengths of all the sides of the shape. The perimeter is measured in units, such as centimeters, meters, feet, or inches, depending on the unit of measurement used for the dimensions of the shape.

The perimeter of a rectangle is given by the formula:

P = 2l + 2w

where P is the perimeter, l is the length, and w is the width.

In this case, we know that the perimeter is 34 units, and the width is 6.5 units. So we can substitute these values into the formula and solve for the length:

34 = 2l + 2(6.5)

Simplifying, we get:

34 = 2l + 13

Subtracting 13 from both sides, we get:

21 = 2l

Dividing both sides by 2, we get:

l = 10.5

So the equation to determine the length of the rectangle is:

2l + 2w = P

Substituting the known values, we get:

2l + 2(6.5) = 34

Simplifying and solving for l, we get:

2l + 13 = 34

2l = 21

l = 10.5

Therefore, the length of the rectangle is 10.5 units.

In order to create 728 millilitres of the medication, 273 millilitres of component A are required.

A compound in chemistry is a material comprised of two or more separate chemical elements mixed together in a certain proportion. Chemical connections that are challenging to break are created when the elements interact with one another.

Compound A:Compound B ratio in the medication is 3:5. In other words, there are 3 millilitres of compound A and 5 millilitres of compound B for every 3+5=8 millilitres of the medicine.

We may set up a percentage using the ratio of compound A to the total volume of the medicine to determine how much compound A is required to make 728 millilitres of the drug:

3 ml x 3 ml x 3 ml

-------- = ----------

728 ml total, 8 ml overall

If we cross-multiply, we obtain:

8(x) = 3(728)

To find x, we use the formula x = 3(728)/8 = 273

273 milliliters of compound A are needed to make 728 milliliters of the drug.

What are proportions?

In mathematics, a proportion is a statement that two ratios are equal. It expresses the relationship between two or more quantities that are directly proportional to each other. A proportion can be represented as an equation of the form:

a/b = c/d

To determine the amount of compound A needed to make 728 milliliters of the drug, we need to use the given ratio of 3 milliliters of compound A to 5 milliliters of compound B.

Let's start by finding the ratio of compound A to the total amount of ingredients (A+B) in the drug:

3 : (3+5) or 3:8

This means that for every 8 milliliters of the drug, 3 milliliters of compound A are used.

To find out how many milliliters of compound A are needed for 728 milliliters of the drug, we can set up a proportion:

3/8 = x/728

where x represents the amount of compound A needed.

To solve for x, we can cross-multiply:

8x = 3*728

8x = 2184

x = 273

Therefore, 273 milliliters of compound A are needed to make 728 milliliters of the drug.

Answer:

There are 360 degrees in one revolution, so a 270-degree clockwise rotation would be the same as a 90-degree counterclockwise rotation. Therefore, the rule would be to map (x, y) to (–y, x).

Step-by-step explanation:

edge answer

The required, to express this rotation using a mapping rule, we can use the coordinates (x, y) of a point and map them to (-y, x).

A rotation of 270 degrees clockwise is equivalent to a 90-degree counterclockwise rotation. This means that the object would be turned to the right by 270 degrees or turned to the left by 90 degrees. To express this rotation using a mapping rule, we can use the coordinates (x, y) of a point and map them to (-y, x).

In simpler terms, if we have a point (x, y) and apply a 270-degree clockwise rotation, the new coordinates would be (-y, x). This means that the original y-coordinate becomes the new x-coordinate, and the original x-coordinate becomes the negative of the new y-coordinate.

For example, if we have a point (2, 4) and apply a 270-degree clockwise rotation, the new coordinates would be (-4, 2).

By using this mapping rule, we can accurately determine the new positions of points after a 270-degree clockwise rotation.

Answer:

slope= 0

y- intercept= (0, 17)

Step-by-step explanation:

Assuming that his age is the independent variable and the number of freckles is the dependent variable, the graph plotted is a number of freckles vs age graph.

At birth

Age= 0 years old

Number of freckles= 17

Point to be plotted is (0, 17)

10 years old

Age= 10 years old

Number of freckles= 17

Point to be plotted is (10, 17)

After plotting the two points (see attached graph), you would notice that the line joining these two points is a horizontal line. Horizontal lines have a slope of zero. This can also be found using the formula, slope= rise/ run.

The y-intercept is the point at which the graph cuts through the y-axis and occurs at x= 0. Thus, the y-intercept occurs at (0, 17) or y= 17.

Answer:

slope = 0

y-intercept = 17

Step-by-step explanation:

Let x = age of Eamon in years

Let y = number of freckles

Create 2 ordered pairs from the information given:

17 freckles at birth = (0, 17)

17 freckles at 10 years old = (10, 17)

Slope formula:  \(m=\dfrac{\textsf{change in} \ y}{\textsf{change in} \ x}\)

Therefore, \(m=\dfrac{17-17}{10-0}=0\)

So the slope is zero

y-intercept is where the line crosses the y-axis, so when x = 0.

We already know that y = 17 when x = 0, therefore the y-intercept is 17.

Therefore, the final equation for the line is:  y = 17

Taking squares on both sides leads to

\(\sqrt{-x + 6} = x - 6\)

\(\left(\sqrt{-x + 6}\right)^2 = (x - 6)^2\)

\(-x + 6 = x^2 - 12x + 36\)

\(x^2 - 11x + 30 = 0\)

\((x - 5) (x - 6) = 0\)

Solving for \(x\), we get

\(x - 5 = 0 \text{ or } x - 6 = 0\)

or

\(x = 5 \text{ or } x = 6\).

Evaluating both sides of the starting equation at these solutions, we have

\(\sqrt{-6 + 6} = 6 - 6 \implies 0 = 0\)

which is true, so \(\boxed{x=6}\) is a valid solution. However,

\(\sqrt{-5 + 6} = 5 - 6 \implies \sqrt1 = -1 \implies 1 = -1\)

which is not true, so \(\boxed{x=5}\) is an extraneous solution.

Your want to isolate the x. This is a multiplication problem, so use the inverse operation, which is division. Divide both sides of the equation by

1/4 by multiplying by the reciprocal, 4. (− 5

8)(4) is − 5/2. Use substitution to check the answer. x = − 5/2 :)

Answer: First, you isolate x by dividing 1/4 on both sides.  

1/4x divided by 1/4 equals zero, which just leaves x, and -5/8 divided by 1/4 equals -5/2, so x = -5/2. -5/2 can be simplified to -2.5,  

To check the answer, substitute x for -5/2:

* 1/4 multiplied by -5/2 equals -5/8

* 5/8 = 5/8, so this proves that my answer is correct.

Therefore , the solution of the given problem of standard deviation comes out to be option C with n = 1,000 and p near to 1/2 is the right response.

Statistics uses variance as a way to quantify difference. The image of the result is used to compute the average deviation between the collected data and the mean. Contrary to many other valid measures of variability, it includes those pieces of data on their own by comparing each number to the mean. Variations may be caused by willful mistakes, irrational expectations, or shifting economic or business conditions.

Here,

The following algorithm determines the standard deviation of the sampling distribution of a sample proportion p:

=> √((p*(1-p))/n)

where n is the sample size, and p is the population percentage.

For the sampling distribution of a sample proportion p,

the pair of sample number n and population proportion p that would result in the highest standard deviation is:

=>n =1,000, and p is almost half.

Because p=1/2

yields the highest possible value of the expression (p*(1-p)), a bigger sample size will result in a smaller standard deviation.

The standard deviations will be lower for the other choices, which have smaller sample sizes or extreme values of p.

Therefore, (C) with n = 1,000 and p near to 1/2 is the right response.

The component form of the following vectors is Option A. V = (38.3, 32.1).

To find the component form of a vector given its magnitude and direction angle, we can use trigonometry.

The component form of a vector in two dimensions is represented as (x, y), where x is the horizontal component and y is the vertical component.

In this case, the magnitude of the vector is given as 50, and the direction angle θ is 50°. We can use this information to calculate the horizontal and vertical components.

The horizontal component (x) can be found using the formula x = magnitude * cos(θ), and the vertical component (y) can be found using y = magnitude * sin(θ).

Let's calculate the components:

x = 50 * cos(50°) ≈ 38.3

y = 50 * sin(50°) ≈ 32.1

Rounding the answers to the nearest tenth, we get the component form of the vector V as (38.3, 32.1).
