Consecutive integers are a set of positive whole numbers which follows one another respectively. Thus the required proof to the question is as explained below:
What si Pythagoras?The theorem states that:[tex]/hypotenuse/^{2}[/tex] = [tex]/adjacent/^{2}[/tex] + [tex]/opposite/^{2}[/tex]Thus a set of consecutive numbers which represent each side of a right angled triangle must obey the Pythagorean theorem.
Consecutive integers are a set of positive whole numbers which follows one another respectively. Examples are; 20, 21 and 22, 2, 3 and 4 etc.Therefore, the three consecutive integers that are also Pythagorean tribble are 3, 4 and 5.
So that let the adjacent side be 3, and the opposite side 4, then;[tex]/hypotenuse/^{2}[/tex] = [tex]/adjacent/^{2}[/tex] + [tex]/opposite/^{2}[/tex] = [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = 9 + 16 = 25
hypotenuse = [tex]\sqrt{25}[/tex] = 5
Therefore the common three consecutive integers that are Pythagoras tribble are 3, 4 and 5.

Carly is a catcher on the school softball team. By the end of the season she had played in 45 percent of the 40 games the team played. In how many games did Carly NOT play.
Number of games did Carly NOT play is 22.
How to calculate percentage?
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given:
Total number of games = 40
It is given that she had played in 45 percent of the 40 games the team played.
Number of games she played = 45% of 40
= [tex]\frac{45}{100}\times 40= 18[/tex]
Number of games she did not play = 40 - 18 = 22
Therefore, number of games did Carly NOT play is 22.

Teen cigarette use is down the us centers for disease control conducts the national youth tobacco survey each year. The preliminary results3 of 2019 show that e-cigarette use is up among us teens while cigarette use is down. We examined e-cigarette use in exercise 3. 137 and here we estimate cigarette use. In the sample of 1582 teens, 92 reported smoking a cigarette in the last 30 days. Give notation and define the parameter we are estimating. Give notation and value of the sample statistic. Find the standard error for this estimate. What is z* for a 99% confidence interval? what is the 99% confidence interval? what is the best estimate for the parameter we are estimating? what is the margin of error?
Answer of the following questions as per the given sample and confidence interval are:
The sample statistic value for the give samples is 0.058.The standard error for the given estimate is equal to 0.0068.The z score for 99% confidence interval is 2.576.The best estimate is the sample mean.Margin of error is equal to 0.0176.As given in the question,
Number of teens smoking cigarette = 92
Sample size 'n' = 1582
Sample statistic = 92 / 1582
= 0.058
Standard error = √ p ( 1 - p ) / n
= √ 0.058 ( 1 - 0.058 ) / 1582
= √0.0000345
= 0.0058
= 0.006
z-score for 99% confidence interval = 2.576
margin of error = z ×√ p ( 1 - p )/n
= 2.576 √ 0.058 ( 1 - 0.058 ) / 1582
= 2.576 × 0.006
= 0.0155
= ±0.016
lower bound = 2.576 - 0.016
= 2.56
Upper bound = 2.576 + 0.016
= 2.592
Therefore, for the given samples and confidence interval answer of the following questions are:
The sample statistic value for the give samples is 0.058.The standard error for the given estimate is equal to 0.0068.The z score for 99% confidence interval is 2.576.The best estimate is the sample mean.Margin of error is equal to 0.0176.Learn more about confidence interval here

What is temperature?
The degree to which an object is hot or cold is measured by its temperature.

How can you summarize the ruler placement postulate? you can measure the between points a and b by using as zero.
The summary of the ruler placement postulate is: A direct relationship exists between the set of points on the line and the collection of real numbers, where each point is matched to a single real number and The magnitude of the gap between two points is equal to the absolute value of the subtraction of the two associated values.
The ruler placement postulate states that if two points are given, it is possible to measure the distance between them by taking the point of reference as zero. This means that any point can be chosen as an origin, and the distance between the two points can be calculated by measuring the number of units between them. This postulate also applies to curves, and the distance between two points on a curve can be measured by taking a point of reference as zero and measuring the number of units between them. This postulate is essential in the measurement of distances between points and curves in geometry.

Answer:
The values that are solutions to K-3 >-2 are -7 and -5. To solve this inequality, we need to isolate the K term on one side of the inequality. We can do this by subtracting 3 from both sides of the inequality, like this:
K - 3 > -2
K - 3 - 3 > -2 - 3
K > -5
Therefore, the solutions to the inequality K-3 >-2 are all values of K that are greater than -5. This means that the values -7 and -5 are solutions to the inequality, but the other values listed are not.

To lift a load of 100 n a distance of 1 m an effort of 25 n must be applied over an inclined plane of length 4 m. What must be done to lift the load 2 m, using the same effort?.
An inclined plane of length 8 m is used to lift the load 2 m, using the same effort.
A ramp that helps lift and lower heavy things is called an inclined plane. It is a flat surface that is positioned against a horizontal surface at an angle other than a right angle.
Work is defined as the use of force to move an object over a distance. It is derived as the product of displacement (d) and force (F). Work is given by W = F×d = 25 N×d.
When a body is lifted, we can express work as W = m×g×h where g is gravity and h is height. And the force is written as F = m×g where m is the mass of an object. Then, W = F×h
Calculating the work done to lift the load to 2 m, we get,
W = 100 N×2 m = 200 Nm.
Substitute this value in W = F×h, we get,
200 Nm = 25 N×d
Divide both sides by 25 N, and we get,
[tex]\begin{aligned}\frac{\mathrm{200\;Nm}}{\mathrm{25\;N}}&=\frac{\mathrm{25\;N\times d}}{\mathrm{25\;N}}\\d&=\mathrm{8\;m}\end{aligned}[/tex]
The value is 8 m. Therefore, the first statement is correct.
The complete question is -
To lift a load of 100 N a distance of 1 m an effort of 25 N must be applied over an inclined plane of length 4 m. What must be done to lift the load 2 m, using the same effort?
A. Use an inclined plane of length 8 m.
