Given: S is on the segment RT. RS = x + 2, ST = 3x + 1, and RT = 15.

Answers

On solving the question we have that We can see that RS + ST = RT, equation  confirming that S is on segment RT: RT = RS + ST = 5 + 10 = 15

What is equation?

A math equation is a mechanism for connecting two statements and indicating equivalence with the equals sign (=). To explain the connection between the two sentences put on each side of a letter, a statistical method can be employed. The software and the logo are usually interchangeable. 2x - 4 equals 2, for example. An equation is a logical expression that asserts the equality of some mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the numbers 3x + 5 and 14.

Because S is on the section RT, we know that RS + ST = RT. As a result, we may construct the following equation:

RS + ST = 3x + 1 + (x + 2) = 15

To simplify this equation, we can combine similar terms:

4x + 3 = 15

Subtraction of 3 from both sides yields:

4x = 12

When we divide both sides by 4, we get:

x = 3

RS = x + 2 = 5 and ST = 3x + 1 = 10 as a result.

We can see that RS + ST = RT, confirming that S is on segment RT:

RT = RS + ST = 5 + 10 = 15

Using Pythagoras' theorem, work out the horizontal distance between the wallI and the bottom of the ramp. Give your answer in inches to 1 d.p.​

Answers

Answer:

Horizontal distance between the wall and the bottom of ramp = 25.4 inches.

Step-by-step explanation:

Pythagorean theorem:

          AB  -> wall ;  AB =  14 inches    

         AC -> Wooden plank ; AC = 29 inches

        BC -> horizontal distance between the wall and the bottom of ramp(pank).

           Pythagorean theorem,

                       [tex]\boxed{\bf base^2 + altitude^2 = hypotenuse^2}[/tex]

                         BC² + AB² = AC²

                           BC² + 14² = 29²

                          BC² + 196 =  841

                                     BC² = 841 - 196

                                             = 645

                                       BC = √645

                                       BC = 25.4 inches

Horizontal distance between the wall and the bottom of ramp = 25.4 inches.

Given,

Length = 29 inches

Height = 14inches

Here,

Pythagorean theorem:

AB  -> wall ;  AB =  14 inches    

AC -> Wooden plank ; AC = 29 inches

BC -> horizontal distance between the wall and the bottom of ramp (plank).

Pythagorean theorem,

Base²  + Perpendicular² = Hypotenuse²

BC² + AB² = AC²

BC² + 14² = 29²

BC² + 196 =  841

BC² = 841 - 196

= 645

BC = √645

BC = 25.4 inches

I choose 10 consecutive numbers. if I exclude one of the numbers the remaining 9 sum to 2023 which number did I exclude?

Answers

Answer:

the number 228

Step-by-step explanation:

Let's call the smallest number in the consecutive sequence "x". Then, the 10 consecutive numbers are x, x+1, x+2, x+3, x+4, x+5, x+6, x+7, x+8, and x+9.

If we exclude one of these numbers, then the sum of the remaining 9 numbers would be:

(x) + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) + (x+6) + (x+7) + (x+8) or 9x + 36.

We know that the sum of the remaining 9 numbers is 2023, so we can set up the equation:

9x + 36 = 2023

Solving for x, we get:

9x = 1987

x = 221

Therefore, the smallest number in the consecutive sequence is 221, and the 10 numbers are 221, 222, 223, 224, 225, 226, 227, 228, 229, and 230.

If we exclude the number 228, then the sum of the remaining 9 numbers is 2023.

Karen has two dogs. The larger dog weighs 1. 4 pounds more than the smaller dog. The combined weight of the two dogs is 12. 6 pounds

Answers

The weight of the smaller dog is 5.6 pounds.

Let the weight of the smaller dog be x, then,

The weight of the larger dog = 1.4 pounds.

The combined weight of the dogs =  12.6 pounds.

Therefore,

The sum of the weight of the larger dog and smaller dog = the combined weight of the dogs.

That is,

1.4 + x + x = 12.6

1.4 + 2x =  12.6

2x = 12.6 - 1.4

For the equilateral triangles we have:

1) x = 5, y =  √50

2) a = 2, b = √8

3)y = 8, x = √128

4) a = b = 7/√2

How to find the missing sides?

We can see some triangles, remember that for a right triangle whose angles are 45°, we have an equilateral triangle.

So the two legs have the same measure.

1) Here we can see that x = 5, and the hypotenuse is given by:

y^2 = 5^2 + 5^2

y^2 = 50

y = √50

2) Here we have a = 2, then the hypotenuse is:

b^2 = 2^2 + 2^2

b^2 = 8

b = √8

3) Here we have y = 8, then the hypotenuse is:

x^2  = 8^2 + 8^2

x^2 = 128

x = √128

On the last triangle we can see that the hypotenuse is 7, and we know that a = b

then:

7^2 = a^2 + b^2

7^2 = a^2 + a^2

49 = 2*a^2

(49/2) = a^2

√(49/2) = a

7/√2 = a = b

A company's profit (in millions of dollars) can be represented by y=x^2 -16x +67 where x is the number of years since the company started. When did the company have a profit of 7 million dollars?

Answers

For given quadratic equation, the company had a profit of 7 million dollars in either its 6th year or its 10th year of operation.

What exactly are quadratic equations?

A quadratic equation is a second-degree polynomial equation of the form:

ax²+ bx + c = 0

where x is the variable and a, b, and c are constants, with a ≠ 0. The term "quadratic" comes from the Latin word "quadratus", which means "square". In other words, a quadratic equation is an equation that involves the square of the variable x.

Now,

We are given that the profit of the company (in millions of dollars) can be represented by the equation y = x² - 16x + 67, where x is the number of years since the company started.

We want to find when the company had a profit of 7 million dollars.

So, we can set y = 7 in the equation:

7 = x² - 16x + 67

Rearranging and simplifying:

x² - 16x + 60 = 0

Now, we can solve for x using the quadratic formula:

x = (-(-16) ± √((-16)^2 - 4(1)(60))) / 2(1)

x = (16 ± √(16)) / 2

x = 8 ± 2

Therefore, the solutions are x = 10 or x = 6.

This means that the company had a profit of 7 million dollars in either its 6th year or its 10th year of operation.

​ is . (Round to one decimal place as needed.)

Answers

Value of Q3 is approximately 114.1 given mean and standard deviation.

We must identify the IQ score that separates the bottom 9% from the top 91% in order to determine P9. The normal distribution of IQ scores has a mean of 100 and a standard deviation of 15, as is well known. The z-score for the 9th percentile can be calculated using a calculator or a typical normal distribution table.

[tex]z = invNorm(0.09) = -1.34[/tex]

The formula for converting a z-score to an IQ score is as follows:

IQ equals z * standard deviation + mean, or -1.34 * 15 + 100, or 79.1.

P9 is therefore roughly 79.1.

We must identify the IQ score that distinguishes the top 25% from the rest in order to determine Q3. Assuming a normal distribution, IQ values have a mean of 105 and a standard deviation of 15. Since the top 25% and the 75th percentile are the same, we can use a calculator or a conventional normal distribution table to determine the z-score that represents the 75th percentile:

[tex]z = invNorm(0.75) = 0.67[/tex]

We can then use the formula for transforming a z-score to an IQ score:

IQ = z * standard deviation + mean = 0.67 * 15 + 105 = 114.05

Therefore, Q3 is approximately 114.1.

a) The populations in 1980, 1990, 2000, and 2010 are 157,000, 218,000, 269,000, and 308,000 respectively.

b) the population will reach 390,000 in 270 years

c) No, as t increases, the population increases rapidly

How to find the populations as required

(a) To find the population in 1980, 1990, 2000, and 2010, we substitute the corresponding values of t into the given model and round the answers to the nearest whole number.

Population in 1980: P = 75.9e^(0.0316*10) = 156,604

Population in 1990: P = 75.9e^(0.0316*20) = 217,643

Population in 2000: P = 75.9e^(0.0316*30) = 269,099

Population in 2010: P = 75.9e^(0.0316*40) = 308,227

(b) To find when the population of Horry County will reach 390,000, we need to solve the equation 390 000 = 75.9e^(0.0316t) for t.

Taking the natural logarithm of both sides, we get:

ln(390,000/75.9) = 0.0316t

Simplifying, we get:

t = ln(390,000/75.9)/0.0316 ≈ 270.395

Rounding down to the nearest whole year, we get that the population will reach 390,000 in 270 years

(c) The model assumes that the population growth rate will remain constant over time. However, in reality, population growth rates can be affected by a variety of factors, such as changes in birth and death rates, immigration, emigration, and natural disasters.

Therefore, it is unlikely that the model will be valid for long-term predictions of the population. The model can provide a good estimate of the population for the short-term, but it is not reliable for predictions far into the future.

Given data:

pH of lye = 12.13

Using the formula pH = -log[H+], we have to find the hydrogen ion concentration, [H+].

Now, putting the given values in the formula, we get:

pH = -log[H+]

12.13 = -log[H+]

log[H+] = -12.13

[H+] = 10^-12.13 = 5.01187 x 10^-13

So, the hydrogen ion concentration, [H+] is 5.01187 x 10^-13 moles/liter. Therefore, the answer is 5.01187 x 10^-13.

The value of q in the question is q>-12/15

What is an inequality?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions

The given inequality is 5(p−3q)<12

Opening the bracket we have

5p - 15q < 12

The solution can only be gotten if we assume p = 0

the substitute p=0 in the inequality to have

-15q < 12

dividing both sides by -15 to have

-15q/-15 < 12/-15

therefore q > 12/-15

Use the equation y = 7x to complete the table. What are the missing values of

y?




O A. When x = 2, y = 16.

When x = 4, y = 30.

O B. When x = 2, y = 14.

When x = 4, y = 28.

C. When x = 2, y = 8.

When x = 4, y = 22

D. When x = 2, y = 12.

When x = 4, y = 24.

Answers

Using the equation y = 7x , we can compute that when x = 2, y = 14 and when x = 4 , y = 28. So, correct option is B.

The equation y = 7x relates the variables y and x, where y is a function of x. To compute the value of y for a given value of x, we simply substitute that value of x into the equation and solve for y.

When x = 2, we can substitute this value into the equation:

y = 7(2) = 14

Therefore, when x = 2, y = 14.

Similarly, when x = 4, we can substitute this value into the equation:

y = 7(4) = 28

Therefore, when x = 4, y = 28.

So, the correct option is B: When x = 2, y = 14 and when x = 4, y = 28.

In summary, to compute the value of y for a given value of x using an equation, we substitute that value of x into the equation and solve for y. In this case, when x = 2, y = 14, and when x = 4, y = 28, according to the given equation y = 7x.

the daily high temperature for chattanooga is normally distributed with mean 79 and standard deviation 4. find the probability that a randomly chosen temperature is between 70 and 75.

Answers

The probability of randomly selecting a temperature between 70 and 75 is approximately 0.8291.

To find the probability that a randomly chosen temperature is between 70 and 75, we need to use the z-score formula as shown below:

z = (x - μ) / σ

Where:x = 70 and 75μ = 79σ = 4z1 = (70 - 79) / 4 = -2.25z2 = (75 - 79) / 4 = -1P(70 < x < 75) = P(-2.25 < z < -1)

To find the probability for the above inequality, we need to use a calculator. We know that the probability of the standard normal distribution is equal to 1.

Hence, P(-2.25 < z < -1) = Φ(-1) - Φ(-2.25) = 0.8413 - 0.0122 ≈ 0.8291. Therefore, the probability is about 0.8291.

Leeanne plans to sell her car and places an x-line ad. The newspaper charges p dollars for the
first k lines and e dollars per extra line, to run the ad for a week.
When x > k, write an algebraic expression for the cost of running the ad for a week.
a.
b. When x

Answers

Answer:

a. When x > k, the cost of running the ad for a week can be expressed as:

C = p + e(x - k)

where C is the cost in dollars, p is the cost per k lines, e is the cost per extra line, and (x - k) is the number of extra lines over k.

b. When x ≤ k, the cost of running the ad for a week can be expressed as:

C = p

where C is the cost in dollars and p is the cost per k lines. Since the number of lines x is less than or equal to k, there are no extra lines and the cost is simply the base cost of p dollars for k lines.
