The larger number is x = 71 and the smaller number y is 17

An equation is a mathematical statement showing the equality of two things.

The equations are

x = 14 +3y and x+y = 90

To solve the equations, we substitute x = 14 + 3y in the equation x +y = 90

⇒14+3y+y = 90

Collecting like terms to have

4y = 90-14

4y = 76

Making y the subject

y=76/4

y=19

By substitution we have

x=14+3(19)

x=14+57

Therefore the value of x = 71

An angle that turns through 1/360 of a circle is called a “one-degree angle” and can be used to measure angles.

A degree, generally represented by the symbol ° (the degree), is a unit of measurement for a plane angle, where one full revolution equals 360 degrees.

A degree is the name given to the mathematical unit of measurement for an angle. A protractor is a device used to determine the degree of an angle. Angles can be measured at different angles with different degrees, such as 30°, 45°, 60°, and so on. A complete circle rotates at 360°.

One-degree angles are used to measure angles because they turn around 1/360 of a circle; an angle is said to have an angle measure of n degrees if it turns through n one-degree angles.

The 99th percentile for the mean height of a random sample of 20 adult women is approximately 68.7 inches, which is 3.7 inches above the mean of 65 inches.

The 99th percentile for the mean height of a random sample of 20 adult women can be calculated using the normal distribution. The normal distribution is a bell-shaped curve that describes the probability of a given event occurring. In this case, the mean and standard deviation of the height of adult women is used to calculate the probability of the mean height of a sample of 20 adult women being a certain value. For the 99th percentile, this means that the probability of the mean of the sample of 20 adult women being equal to or less than the value of 68.7 inches is 99%. This value is 3.7 inches above the mean of 65 inches, which is the expected mean height of adult women.

Step-by-step explanation:

The solution to the system of inequalities y ≤ 2x + 2 and y < -2x - 3 can be represented by a graph. The inequality y ≤ 2x + 2 represents a line with a slope of 2 and y-intercept of 2. The inequality y < -2x - 3 represents a line with a slope of -2 and y-intercept of -3. ( The graph attached)

The inequality y ≤ 2x + 2 represents a line in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 2 and the y-intercept is 2. To graph this inequality, we can first plot the line by using the y-intercept, which is the point (0,2) on the graph. Then, we can use the slope to find additional points that fall on the line, such as (1,4) or (-1,0). Once we have plotted several points, we can connect them to form the line.

The inequality y < -2x - 3 represents a similar line, but with a different slope and y-intercept. In this case, the slope is -2 and the y-intercept is -3. To graph this inequality, we can use the same process as before by first plotting the y-intercept (0,-3), and then using the slope to find additional points that fall on the line.

The solution to the system of inequalities is the area that lies on one side of the first line and the opposite side of the second line, which is the area between the two lines. This area can be represented by shading the region below the first line and above the second line on the graph. It is important to note that the solution region is not including the lines themselves, because the inequalities are strict inequalities.

It would take approximately 12.6 years for the value of the car to be $700.

To find out how long it would take for the value of the car to be $700, we can use the formula for exponential decay. The value of the car after t years is:

[tex]V(t) = V_0 \times (1/2)^{(t/k)}[/tex]

Where V₀ is the initial value of the car, t is the time in years, k is the time constant in years, and (1/2) is the decay constant.

Given:

V₀ = $13,000

V(t) = $700

k = 3

Now you can solve for t:

[tex]700 = 13,000 \times (1/2)^{(t/3)}[/tex]

Take the natural logarithm of both sides:

[tex]ln(700) = ln(13,000 \times (1/2))^{(t/3))}[/tex]

[tex]ln(700) = ln(13,000) + ln((1/2)^{(t/3)})[/tex]

ln(700) = ln(13,000) + (t/3) × ln(1/2)

t = 3 × (ln(700) - ln(13,000))/ln(1/2)

t = 12.6 years (rounded to the nearest tenth of a year)

The value of k for which the quadratic equation 3x² + kx + 3 = 0 has equal roots is -3.

The condition for a quadratic equation to have equal roots is that its discriminant, which is given by the expression b² - 4ac, must be equal to 0. In this case, a = 3, b = k, and c = 3. Substituting these values into the expression for the discriminant gives us:

k² - 4 * 3 * 3 = 0.

Solving for k gives us

k = ±√(4 * 3 * 3) = ±6.

Since the coefficient of x in the equation is positive, both roots are real and equal only if k = -6. Hence, the value of k for which the equation 3x² + kx + 3 = 0 has equal roots is -3.

The scale used for measuring the intensity of the earthquake is Richter Scale.

American seismologists Charles F. Richter and Beno Gutenberg developed the Richter scale (ML), a numerical indicator of an earthquake's size, in 1935. The height of the greatest seismic wave, as measured by the logarithm of its amplitude (height), is used to calculate the earthquake's magnitude.

Although the original Richter scale has been supplanted by other, more precise scales in modern science, the Richter scale is still frequently used incorrectly in news reporting of earthquake severity as a catch-all name for the logarithmic scale that earthquakes are measured on.

What is VAT(Value Added Tax) ?

VAT stands for Value Added Tax, it is a consumption tax that is added to the price of goods and services. VAT is imposed on most goods and services in many countries around the world, and it is usually a percentage of the sale price. The percentage can vary depending on the country and the type of goods or services being sold.

To calculate the VAT, we can use the formula:

VAT = (original price x VAT percentage) / 100

So, in this case:

VAT = (250 x 20) / 100 = 50

Now we add the VAT to the original price to find the selling price:

selling price = original price + VAT

250 + 50 = 300 euro.
