The number of adults believes that the divorce is morally wrong is given by 54.8 million.

Given that the total number of adults in the country is = 274 million

Percentage of adults believe that the divorce is morally wrong is given by = 20 %

So the probability of adults believes that the divorce is morally wrong is given by = 20 / 100 = 1 / 5.

The number of adults believes that the divorce is morally wrong is given by

Step-by-step explanation:

area of a circle formula is πr²

Find area of the larger and smaller circles and then subtract to find the shaded region. π = 3.14

area of the larger circle = π (11.5)²

                                      3.14 (132.25)

                                      415.265 units²

area of the smaller circle = π (5.5)²

                                           3.14(30.25)

                                           94.985 units²

subtract:   415.265 - 94.985 = 320.28 units²

Take the differences, it will give 35

Add 35 to 315

The expression 18Y - 3х^2 is read correctly in EWA when variables are case-sensitive.

This means that when you enter the expression, you must make sure that each letter is the same case as it was written in the expression.

For example, in this expression, the letter "Y" is capitalized and the letter "х" is lowercase, so these letters must be written the same way in EWA for the expression to be read correctly.

To enter the expression into EWA, you need to type it in exactly as it is written. First, you must enter the number 18, followed by the capital letter Y.

Next, you must type the minus sign and the number 3. After this, you must enter the lowercase letter х, followed by the caret symbol (^) and the number 2.

It is important to remember that in EWA, variables are case-sensitive, so x is not the same as X. If you enter the expression incorrectly, EWA will not read it properly and you will not get the desired result.

In conclusion, to enter the expression 18Y - 3х^2 into EWA, you must make sure that each letter is the same case as it was written in the expression and type it in exactly as it is written.

9.43 inches is the measure of the longest segment

We are aware that the diagonal connecting the two opposing corners at the top and bottom will be the longest segment.

We know how to find the diagonal of a right triangular prism using the following formula:

d = \(\sqrt{w^2 + l^2+h^2} \\\\\)

where w = width = 1.4

l = length = 4.8

h = height = 8

We would put these values in the formula above

\(d = \sqrt{1.4^2 + 4.8^2+8^2} \\\\\)

d = \(\sqrt{1.96+23.04+64}\)

d = 9.43

Answer:

I think the answer should be two and a half pieces

None of the given options (i.e. a, b, c, or d) is correct.

Given the prices of consumer items, we can find the estimate of the current CPI.

The percentage change in the price of the consumer item over time can be given as:

Percentage change = (Current Price − Price in 1983)/Price in 1983 × 100%

Now, using the percentage change we can find the average percentage change (increase or decrease) in prices. We calculate the average percentage change by finding the sum of the percentage change in prices of all items and then dividing it by the number of items.

Thus, we have:

Average percentage change = [(126.85−67.45)/67.45 + (29.95−15.25)/15.25 + (2.25−1.15)/1.15 + (44.25−22.85)/22.85]/4Average percentage change = 4.4188%

Now, the current CPI can be found using the following formula:

Current CPI = CPI in 1983 × [1 + (Average percentage change)/100]Current CPI = 100 × [1 + 4.4188/100] ≈ 104.42 ≈ 104

Therefore, the reasonable estimate of the current CPI is 104.

Answer is 66.95

The value of c that gives the function \(f(x) = 5x^2 - 10x + c\) a minimum value is c = -1.

To find the value of c that gives the function \(f(x) = 5x^2 - 10x + c a\)minimum value, we need to use the concept of completing the square.

The given function can be rewritten as: \(f(x) = 5(x^2 - 2x) + c\)

To complete the square, we need to add and subtract the square of half of the coefficient of x:

\(f(x) = 5(x^2 - 2x + (2/2)^2 - (2/2)^2) + c\)

\(f(x) = 5[(x - 1)^2 - 1] + c\)

\(f(x) = 5(x - 1)^2 - 5 + c\)

Now we can see that the function is in vertex form: f(x) = \(a(x - h)^2\) + k, where (h, k) is the vertex.

In this case, the vertex is (1, -5/5) = (1, -1), and the minimum value of the function is k = -1.

Therefore, c = k = -1.

So, the value of c that gives the function \(f(x) = 5x^2 - 10x + c\) a minimum value is c = -1.

The point satisfies both equation 1 and 2" and "The point is a solution to the system.

An equation is a mathematical statement that shows the equality of two expressions. Equations can be used to represent relationships between variables and to solve problems. They are written using an equal sign (=) and can include numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

For example, the equation 2x + 3 = 7 is an equation that states that the expression on the left side (2x + 3) is equal to the expression on the right side (7). The goal is to find the value of the variable x that satisfies the equation. In this case, x = 2 is a solution to the equation.

To check whether a point is a solution to a system of equations, we can substitute the values of the variables into the equations and see if the resulting expressions are equal.

So, for the point (-3, -2), we can substitute these values into the equations:

Equation 1: -7x - 4y = 29

Substituting x = -3 , y = -2:

-7(-3) - 4(-2) = 29

21 + 8 = 29

29 = 29

Equation 2: 3x = -7 + y

Substituting x = -3 , y = -2:

3(-3) = -7 + (-2)

-9 = -9

Since both equations are true, the point (-3, -2) satisfies both equation 1 and 2, and is a solution to the system.

Therefore, the true statement from the list is "The point satisfies both equation 1 and 2" and "The point is a solution to the system".

The coordinates of the point that divides the line segment from (6, 2) to (8, -10) into a ratio of 1 to 3 are (7, -1).

To find the coordinates of the point on the directed line segment that partitions it into a ratio of 1 to 3, we can use the concept of section formula.

The section formula states that if we have two points A(x₁, y₁) and B(x₂, y₂) dividing a line segment in the ratio of m₁ : m₂, then the coordinates of the dividing point P are given by:

Px = (m₁ * x₂ + m₂ * x₁) / (m₁ + m₂)

Py = (m₁ * y₂ + m₂ * y₁) / (m₁ + m₂)

In this case, the ratio is 1:3, which means m₁ = 1 and m₂ = 3. The given points are A(6, 2) and B(8, -10). Substituting these values into the formula, we can calculate the coordinates of the dividing point P:

Px = (1 * 8 + 3 * 6) / (1 + 3) = 7

Py = (1 * -10 + 3 * 2) / (1 + 3) = -2/2 = -1

Therefore, the coordinates of the point that divides the line segment from (6, 2) to (8, -10) into a ratio of 1 to 3 are (7, -1).

To find the coordinates of the point that divides the line segment between (6, 2) and (8, -10) in a 1:3 ratio, we can use the section formula. Applying the formula, where m₁ is 1 and m₂ is 3, the point P(x, y) can be determined.

By substituting the values into the formula, the x-coordinate is calculated as (1 * 8 + 3 * 6) / (1 + 3) = 7, and the y-coordinate is (1 * -10 + 3 * 2) / (1 + 3) = -1. Thus, the coordinates of the point that partitions the line segment into a ratio of 1 to 3 are (7, -1).

The function used to represents the time spend by Jasmine in biking for a distance of d miles is given by f(d) = d / 18.

The time Jasmine spends biking is indeed a function of the distance she bikes.

The formula to calculate the time Jasmine takes to bike a certain distance is equal to,

time = distance / speed __(1)

Here the speed is the rate at which Jasmine bikes = 18 miles per hour.

Let us consider 'd' be the distance representing the number of miles Jasmine bikes.

This implies,

The function that represents the time Jasmine spends biking in terms of the distance .

Function f(d)  representing the time Jasmine spends biking for a distance of d miles
