Answer:

x=6

ABC= 135 degrees

Step-by-step explanation:

ABE and CBD are congruent angles (don't remember the theorem)

therefore

3x+27=45

solve for x

x=6

ABC and CBD are supplementary (meaning they add to 180)

Answer:

6

Step-by-step explanation:

The predicate in the conditional statement checks whether the value of variable "a" is less than or equal to 1. However, it does not directly determine if "a" is of type double.

In this specific case, let's break down the code:

1. The expression `(2 + 1) / 2` is evaluated first. Since both 2 and 1 are integers, the division operation `/` results in a floating-point value, specifically 1.5.

2. The result of the expression is then assigned to variable "a" with the statement `a = (2 + 1) / 2`. The value of "a" becomes 1.5.

3. The conditional statement `if (a <= 1)` is evaluated. The comparison `1.5 <= 1` is false because 1.5 is greater than 1.

Therefore, the predicate result for the variable "a" to be a double primitive type in this case is false.

Step-by-step explanation:

The slope of the line is given by the formula

m=(y2-y1)/(x2-x1)

we have

(x1,y1)=(-5,8)

(x2,y2)=(-5,9)

substitute the values in the formula

m=(9-8)/(-5+5)

m=1/0

is undefined

The slope of the line is undefined because is a vertical line

Part 2) Find the slope of the line containing the following points: (8,-6) (9,-6)

we have

(x1,y1)=(8,-6)

(x2,y2)=(9.-6)

substitute in the formula

m=(-6+6)/(9-8)

m=0/1

m=0

The slope of the line is zero because is a horizontal line

Answer:

7, 11, 14 feet from shortest to longest

Step-by-step explanation:

Let's say that the shortest pipe is equal to x, and work from there.

The medium size piece is 4 feet longer than the shortest piece, so it is equal to 4+x

The longest piece is twice as long as the shortest piece, so it is equal to 2 * x.

The three pieces added up make up the 32 feet pipe, so we can write this as

(2*x) + (4+x) + x = 32

2*x + 4 + x + x = 32

4 * x + 4 = 32

subtract 4 from both sides to isolate the x and its coefficient

4 * x = 28

divide both sides by 4 to isolate the x

x= 7

Therefore, the shortest piece is x=7 feet long. The medium piece is x+4=11 feet long, and the longest piece is x*2=14 feet long

If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

The given parameters are

The binomial (x−7) is a factor of the polynomial function f(x)

The above means that

When the function f(x) is divided by x - 7, it has no remainder

So, we have

x - 7

Set to 0

x - 7 = 0

Add 7 to both sides

x = 7

Substitute x = 7 in f(x) = 0

f(7) = 0

Hence, if the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

Step-by-step explanation:

He made a mistake in step one turning the 7 into a -7

\(x^{2}\) - 3x + 7 = 0

Solving:

\(1x^{2}\) - 3x + 7 = 0  ← If the term doesn't have a coefficient, it is considered that the coefficient is 1.

\(1x^{2}\) + (-3x) + 7 = 0 ← Identify the coefficients a, b, and c of the quadratic equation.

Step-by-step explanation:

The equation to solve the height of the trapezoid is 45h = 1,575

Given data ,

Let the area of the trapezoid be A

Now , the value of A = 1,575 cm²

And , the Top(base2) = 63cm and  Bottom(base1) = 27 cm

Area of Trapezoid = ( ( a + b ) h ) / 2

where , a = shorter base of trapezium

b = longer base of trapezium

h = height of trapezium

On simplifying , we get

1,575 = (63 + 27) / 2 x h

1575 = 45h

Hence , the equation is 1575 = 45h

The probability of drawing 2 green balls simultaneously from a bag containing 2 yellow and 4 green balls can be determined using the following method:

First, calculate the total number of balls in the bag. There are 2 yellow balls and 4 green balls, so the total is 6 balls.

Now, let's find the probability of drawing 2 green balls. To do this, consider the number of green balls (4) and the total number of balls (6). When drawing the first green ball, there are 4 green balls out of 6 total balls. Therefore, the probability of drawing one green ball is 4/6.

Since the balls are drawn simultaneously, there's no change in the number of balls for the second draw. So, the probability of drawing a second green ball remains 4/6.

Now, we can calculate the probability of both events occurring simultaneously by multiplying the probabilities:

(4/6) * (4/6) = 16/36

To simplify the fraction, divide both numerator and denominator by their greatest common divisor (4):

16/36 = 4/9

So, the probability of drawing 2 green balls simultaneously is 4/9.

To find the surface area of the figure, we need to consider the individual surfaces and add them together.

First, let's identify the surfaces of the figure:

The lateral surface area of the larger prism (excluding the base)

The two bases of the larger prism

The lateral surface area of the smaller prism (excluding the base)

The two bases of the smaller prism

The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.

The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.

To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.

Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.

Without specific measurements or dimensions of the figure, it is not possible to provide a numerical answer. Please provide the necessary measurements or dimensions to calculate the surface area.

Situational factors and analysis factors are both sources of error in measurement.

Situational and analysis factors are both important considerations in measurement, and efforts should be made to minimize their effects on the accuracy and reliability of the results. This can be achieved by using clear and standardized measurement instruments, providing clear instructions and definitions, and ensuring consistent and accurate scoring and statistical analysis techniques.

Situational factors refer to circumstances or conditions that can affect the accuracy and consistency of measurement. In the case of lack of clarity of the scale, including the instructions or the items themselves, this can lead to ambiguity and confusion among respondents, resulting in inconsistent or inaccurate responses.

For example, if the scale asks respondents to rate their satisfaction with a product on a scale of 1 to 5, but does not provide clear definitions or examples of what each number means, respondents may interpret the scale differently and provide inconsistent responses.

Analysis factors, on the other hand, refer to the methods and techniques used to analyze and interpret the data collected from the measurement. Differences in scoring and statistical analysis can introduce error and affect the validity and reliability of the results.

For instance, if different analysts use different methods or criteria for scoring responses, this can lead to different outcomes and interpretations of the data. Similarly, if statistical analysis is not done correctly or is based on flawed assumptions, the results may be misleading or inaccurate.

↠ x² + 2x - 80 = 0

↠ x² + 2x - 80 = 0

↠ x² + 10x - 8x - 80 = 0

↠ x(x +10) -8 (x + 10) = 0
