+0.03
-0.45

Answer: 35.1

Step-by-step explanation:

Note that the altitude to the hypotenuse splits the hypotenuse into segments of lengths 16 and 28.

Using the geometric mean theorem, the length of the altitude to the hypotenuse is [tex]\sqrt{16(28)}=8\sqrt{7}[/tex].

Using the Pythagorean theorem, [tex]x=\sqrt{(8\sqrt{7})^2 +28^2} \approx 35.1[/tex].

The absolute value of a number is always positive, but the number itself can be positive or negative, and there are always two possible solutions for the absolute value equation, one positive and one negative, that are the same distance from 0.

An absolute value equation of the form |x| = k (where k is a constant) will have two solutions, one positive and one negative, that are the same distance from 0 on the number line.

For example, if the equation is |x| = 5, the two solutions of the equation are x = 5 and x = -5.

This is because the absolute value of a number represents the distance of that number from 0 on the number line, and this distance is the same regardless of whether the number is positive or negative. Therefore, for any non-negative value k, there are two numbers that are that distance away from 0, one positive and one negative.

For example, the distance of 5 from 0 is 5 units, and the distance of -5 from 0 is also 5 units. Therefore, |5| = |-5| = 5.

Step-by-step explanation:

To prove that the diagonals of an isosceles trapezoid are congruent, we will first define the terms and draw a diagram of the isosceles trapezoid.An isosceles trapezoid is a quadrilateral with two congruent legs, a pair of parallel bases, and congruent base angles.Let's call the isosceles trapezoid ABCD and let the parallel sides be AB and CD, and the congruent legs be AD and BC. Let the diagonals be AC and BD.Since, AD and BC are congruent legs, therefore ∠BAD = ∠CAD by the definition of congruent legs.And since ABCD is a trapezoid, therefore, AB || CD and therefore, ∠BAD = ∠CBD, due to alternate angles are congruent.Therefore, ∠CAD = ∠CBD, by CPCTC (corresponding parts of congruent triangles are congruent)AC = BD , since both are congruent by ASA (angle-side-angle) congruence.Thus, the diagonals of an isosceles trapezoid are congruent.

The balanced chemical equations, of the combustion reactions found by plugging in the right coefficients in front of the molecules according to the rules of conservation of atoms are;

1) 2C + 2O₂ ⇒ 2CO₂

2) CH₄ + 2O₂ ⇒ CO₂ + 2H₂O

3) 2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O

A combustion reaction is one in which a combustible substance reacts with an oxidizer such as oxygen, to become oxidized.

1) 2C + ...O₂ ⇒ CO₂

The number of carbon atoms in the reaction side of the equation is 2, and the number of oxygen atoms in the reaction side are 2

In the product side of the equation, we get;

The number of carbon atoms = 1

The number of oxygen atoms = 2

The ratio of the number of oxygen atoms in the reaction side to the number of oxygen atoms in the product side = 1 : 1

The ratio of the number of carbon atoms in the reaction side to the number of oxygen carbon in the product side = 2 : 1

Multiplying the O₂ by 2 and the CO₂ by 2, we get;

2) CH₄ +... O₂ ⇒ CO₂ + ....H₂O

Reaction side;

Number of carbon atoms = 1

Number of hydrogen atoms = 4

Number of oxygen atoms = 2

Product side;

Number of carbon atoms = 1

Number of hydrogen atoms = 2

Number of oxygen atoms = 3

You need to deposit $55,555 each year until your retirement to achieve your retirement goal.

To find the amount you need to deposit each year, you need to calculate the present value of your future withdrawals, considering the time value of money and taking into account the interest rate.

One way to do this is to use the formula for present value:

PV = FV/(1 + r)^t

where PV is the present value, FV is the future value, r is the interest rate, and t is the number of years until the future value.

In this case, FV is $50000 per year for 30 years, so the total future value is $50000 × 30 = $1,500,000. And t is 15 years, so the present value is:

PV = $1,500,000/(1 + 0.04)^15 = $1,500,000/1.8 = $833,333

So, you need to deposit $833,333/15 = $55,555 each year until you retire to achieve your goal.

A. 73.91% of respondents were under the age of 30 and did not snore.

B. Data show that snoring is not age-independent as most snorers are over 30 years of age.

A. The first step is to convert all percentage population groups into numbers. This helps make things clearer.

Total number of adults surveyed = 995 adults

Number of adults over the age of 30 = 81.5% of 995

                                                              = 81.5/100 × 995

                                                              = 810.925

                                    ≈ 811(part of the population can be counted).

Number of adults under 30 = 995 - 811 = 184 adults.

Number of all adults who snore = 36.8% of 995

= 36.8/100 × 995 ≈ 366 adults who snore

Of the total 995, 32% of the snorers were over 30 was.

Number of snorers over 30 × 995 ≈ 318 adults

Snorers under 30 = 366 - 318 = 48 adults

Number of under 30s recorded 30 - under 30 snorers

= 184 - 48 = 136

Converting this to percentage: 136/184× 100 = 73.91%

so 73

B. From the data, snoring is not independent of age as most of the people that snored were above 30 years. Snoring is related to the age. This is because that the most of the younger adults did not snore, while more of the older adults snored.

To make a boxplot, we need to know the minimum, Q1, median, Q3, and maximum.

The minimum is the smallest value: 15

The maximum is the largest value: 34

The median is found by arranging the numbers from smallest to largest and finding the middle point:

15, 20, 25, 25, 27, 28, 30, 34; there is not an exact middle here so we take the two middlemost points and divide by 2: 25+27/2 = 52/2 = 26

Q1 takes the numbers to the left of the median and finds the middle of those points. 15, 20, 25, 25. Again, there is no exact middle, so we use the same method as above. 20+25/2 = 22.5

Q1 takes the numbers to the right of the median and finds the middle of those points. 27, 28, 30, 34. Again, there is no exact middle, so we use the same method as above. 28+30/2 =  29

The product of two rational numbers is a rational number.

In any field containing integers, rational numbers, along with addition and multiplication, produce a field that also contains the integers. In other words, a field only has characteristic zero if and only if it contains the field of rational numbers as a subfield. The field of rational numbers is a prime field.

"A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator 'p' and a non-zero denominator 'q'."

Therefore, when we are multiplying two rational numbers, their product must be a rational number.

This is because, numerators of both rational numbers are integers and denominators of both the numbers are non-zero integers.

Hence, the product is a rational number.

The domain and range for the function W = 15T + 400 is domain = set of all real numbers from 0 to 90 and range = set of all real numbers from 400 to 1750.

What is the range and domain of a function?

A function's range includes all conceivable values for y. Y = f(x) is the formula to determine a function's range. It is only a function in a relation if each x value has exactly one y value.

The collection of all potential inputs for a function is its domain.

The function for Total amount of water in the tank is given as -

W = 15T + 400

Where, T is the total number of minutes when the water is added.

So, according to the definition of range and domain -

T = domain = Number of minutes when the water is added

W = range = Total amount of water in the tank

W was a function of T for the next 90 minutes.

So, the domain will be the set of all real numbers from 0 to 90.

At, T = 0 -

W = 15(0) + 400

W = 400

At, T = 90 -

W = 15(90) + 400

W = 1350 + 400

W = 1750

So, the range will be set of all real numbers from 400 to 1750.

the sumof angles of triangle is 180

so 6x+10+x+17+4x-34=180

11x-7=180

11x=187

x=17

Answer:

x = 17

Step-by-step explanation:

Since we know the angles of a triangle add up to 180, we can make the equation:

6x + 10 + x + 17 + 4x - 34 = 180

Then, we add 34 to both sides and put like terms near each other:

6x + x + 4x + 10 + 17 = 214

Then, combining like terms and subtracting 27 from both sides gives us:

11x = 187

Divide both sides by 11 gives us:

x = 17

So, the value of x = 17.

The equation of the curve in the XY-plane that passes through (0,3) and whose tangent line at a point (x,y) has slope 2x/y^2 is y^2 = 2x*F(x,y) or y^2 = 2x*F(x,y) + C where C is constant.

The equation of a curve in the xy-plane is given by F(x,y) = 0. To find such a curve that passes through the point (0,3) and whose tangent line at a point (x,y) has a slope of 2x/y^2, we can use the method of implicit differentiation.

First, we can find the equation of the tangent line at a point (x,y) on the curve by computing the derivative of F(x,y) with respect to x and setting it equal to 2x/y^2. This gives us:

F_x(x,y) = 2x/y^2

Next, we can use the fact that the curve passes through the point (0,3) to set up the following equation:

F(0,3) = 0

Solving for F(x,y) in terms of x and y and substituting in the equation for F_x(x,y) gives the implicit equation of the curve is

y^2 = 2x*F(x,y) or y^2 = 2x*F(x,y) + C where C is constant

This is the equation of a curve in the XY-plane that passes through the point (0,3) and whose tangent line at a point (x,y) has a slope of 2x/y^2.

Therefore, The equation of the curve in the XY-plane that passes through (0,3) and whose tangent line at a point (x,y) has slope 2x/y^2 is y^2 = 2x*F(x,y) or y^2 = 2x*F(x,y) + C where C is constant.

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

A percentage is a ratio of one unit of an event's result to the entire sample multiplied by 100%. It denotes parts per 100. We divide the percentage of the sample that liked the options by the total sample to arrive at the calculation. As a result, we compute:
