To show that a statement is false, we need to find a counterexample where the statement does not hold true. Here are the counterexamples for each statement:

The sum of any three odd numbers is even.

Counterexample: 1 + 3 + 5 = 9, which is an odd number. Therefore, the statement is false.

When an even number is added to the product of two odd numbers, the result will be even.

Counterexample: 1 {square} 3 + 2 = 5, which is an odd number. Therefore, the statement is false.

When an odd number is squared and divided by 2, the result will be a whole number.

Counterexample: Let's take an odd number, say 3. If we square it, we get 3{square}2 = 9. If we divide 9 by 2, we get 4.5, which is not a whole number. Therefore, the statement is false.

In each of these cases, we have found a counterexample that shows that the statement is false. It is important to remember that just because a statement holds true for some examples, it does not necessarily mean it holds true for all examples. Finding counterexamples is an important tool in mathematical reasoning and can help us to refine and improve our understanding of mathematical concepts.

It should take Danielle 4 hours, or 240 minutes (since 1 hour = 60 minutes), to be 12 miles ahead of David.

What is the relative velocity?

Relative velocity is the velocityof an object or a person with respect to another object or person. It is the rate at which one object is moving with respect to another object. In other words, relative velocityis the speed at which an object is moving relative to a reference point.

To answer this question, we can use the formula:

time = distance / relative speed

Here, we need to find the time it takes for Danielle to be 12 miles ahead of David. Let's assume that t is the time in hours it takes for Danielle to be 12 miles ahead of David.

During this time, Danielle would have covered 12 more miles than David. Therefore, the distance between Danielle and David will be 12 miles.

Relative speed between them can be calculated by subtracting David's speed from Danielle's speed, since they are running in the same direction. So, relative speed will be:

relative speed = Danielle's speed - David's speed

= 7 - 4

= 3 miles per hour

Now, we can substitute the values of distance and relative speed in the formula to find the time it takes for Danielle to be 12 miles ahead of David:

time = distance / relative speed

= 12 miles / (3 miles per hour)

= 4 hours

Hence, it should take Danielle 4 hours, or 240 minutes (since 1 hour = 60 minutes), to be 12 miles ahead of David.

As a result, if the two angles' measurements are (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.

An angle is a geometric figure formed by two rays that have a common endpoint, called the vertex. The rays are also known as the sides or legs of the angle. Angles are typically measured in degrees, with a full circle measuring 360 degrees. Angles can also be measured in radians, which are another unit of angular measurement used in mathematics and physics. One radian is equal to the angle subtended by an arc of a circle that has a length equal to the radius of the circle. The size of an angle is determined by the amount of rotation that occurs between the two rays. This is typically measured relative to the positive x-axis, with counterclockwise rotations being considered positive and clockwise rotations being considered negative. Angles are used in a wide range of mathematical and scientific applications, including geometry, trigonometry, physics, engineering, and architecture. They are also used in many everyday situations, such as measuring the size of an opening or the angle of incidence of sunlight on a surface.

Here,

If the two angles are congruent, then they must have the same measure.

So we can set the expressions for the measures of the two angles equal to each other and solve for y:

3y + 11 = 11y + 15

Subtracting 3y from both sides:

11 = 8y + 15

Subtracting 15 from both sides:

-4 = 8y

Dividing both sides by 8:

y = -1/2

Therefore, if the measure of the two angles is (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.

The output the last three characters of a string, we need to create a variable to store the string, assign the string to the variable, and use the string slicing method to extract the last three characters

To start, we need to create a variable to store our string. We can name this variable "str". Next, we need to assign our string to the variable. We can do this by using the assignment operator "=".

Now, we can begin manipulating the string to output the last three characters. To do this, we can use the string slicing method. This method allows us to extract a portion of the string by specifying the start and end indices. In this case, we want to start at the third-last character, so our start index will be -3. Since we want the last three characters, our end index will be -1. We can use this information to create the following code:

str = "hello"

last_three_characters = str[-3:-1]

Now, when we print the variable last_three_characters, it should output "lo". This is because the slicing method extracts the characters from the start index up to, but not including, the end index.

Here in the given diagram all the sides are equal and the diagonals are perpendicular. So the given parallelogram is a rhombus.

Here the data given are

ABCD is a parallelogram

∠BOC = 90°

So AOB = 180 - ∠BOC ( angle of a straight line is 180°)

The total area of the composite figure represented by the scale drawing is 2,168.1 square yards.

Measurements refer to the process of assigning numerical values to physical quantities such as length, mass, time, temperature, and many others. These numerical values are expressed in units, which are standardized and accepted values used for comparison and communication.

Measurement is an essential part of science, engineering, and many other fields where precise and accurate data is required. Measurements allow us to make quantitative comparisons, analyze data, and draw conclusions.

There are different methods of measurement depending on the physical quantity being measured. For example, length can be measured using a ruler or tape measure, mass can be measured using a scale, and time can be measured using a clock or stopwatch.

It is important to note that measurements can have errors due to various factors such as limitations of the measuring instruments, environmental factors, and human error. Therefore, it is crucial to understand the limitations of the measuring instruments and to take steps to reduce errors as much as possible.

Overall, measurements are an important tool for gaining knowledge and understanding of the physical world, and they play a critical role in many aspects of our daily lives.

To find the total area of the composite figure represented by the scale drawing, we need to use the scale to convert the measurements in inches to measurements in yards, and then use these measurements to calculate the areas of the individual shapes and add them together.

Let's assume that we have labeled the various shapes in the composite figure A, B, C, and D, as shown in the scale drawing.

To convert the measurements in inches to yards, we need to divide each measurement in inches by 36 (since there are 36 inches in a yard) and then multiply by the scale factor of 9 yards per inch. This gives us the measurements in yards:

Shape A: 3 inches x 9 yards/inch = 27 yards (length), 2 inches x 9 yards/inch = 18 yards (width)

Shape B: 5 inches x 9 yards/inch = 45 yards (length), 3 inches x 9 yards/inch = 27 yards (width)

Shape C: 3 inches x 9 yards/inch = 27 yards (diameter)

Shape D: 2 inches x 9 yards/inch = 18 yards (length), 2 inches x 9 yards/inch = 18 yards (width)

Now we can calculate the areas of each shape using the appropriate formulas:

Area of Shape A: length x width = 27 yards x 18 yards = 486 square yards

Area of Shape B: length x width = 45 yards x 27 yards = 1,215 square yards

Area of Shape C: (pi x (diameter/2)^2)/4 = (pi x (27/2)^2)/4 = 143.1 square yards (using the formula for the area of a circle)

Area of Shape D: length x width = 18 yards x 18 yards = 324 square yards

Finally, we can add up the areas of all four shapes to get the total area of the composite figure:

Total area = 486 square yards + 1,215 square yards + 143.1 square yards + 324 square yards

Total area = 2,168.1 square yards

Therefore, the total area of the composite figure represented by the scale drawing is 2,168.1 square yards.

The value of the term 14 times 39 can be expressed as the value of 2.7857.

Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.

Or, how do you increase something by 14 to get 39? If "x" in the phrase "14 times what = 39?" is "what," then the equation to use to solve the issue is as follows:

14 • x = 39

which is spelled out as:

14x = 39

In order to get the x alone, we must take the 14 from the left side of the equation. We multiply both sides by 14 to achieve that.

14x/14 = 39/14

39/14 is 2.7857 and 14x/14 equals x, thus our equation will be as follows:

x = 2.7857

Therefore, the result of 14 times what is 39 is 2.7857.

The antiderivative of ln x is (1/2)(ln x)^2 + C, where C is any constant. The natural logarithm function ln x is defined only for positive x, so the antiderivative is also defined only for positive x.

The antiderivative (also called the indefinite integral) of ln x is a function that, when differentiated, gives ln x. The symbol for the antiderivative is ∫ln x dx.

To find the antiderivative of ln x, we can use integration by substitution. We start by rewriting ln x as 1 times ln x, and then we use the substitution u = ln x. This means that du/dx = 1/x, or dx = x du.

Substituting these expressions into the integral gives:

∫ln x dx = ∫1 ln x dx = ∫u du

Now we can integrate u with respect to itself:

∫u du = (1/2)u^2 + C

Substituting back u = ln x, we get:

∫ln x dx = (1/2)(ln x)^2 + C

where C is the constant of integration.
