To find the consecutive even positive integers, we set up an equation based on the given information and solve for the variables.

Let's assume the first even positive integer is x. Therefore, the next consecutive even positive integer will be x + 2. According to the problem, the product of these two integers is 782 more than their sum. We can set up the equation as x(x + 2) = x + x + 2 + 782.

Simplifying the equation, we get x^2 + 2x = 2x + 784.

By solving this quadratic equation, we find that the value of x is 26. Therefore, the consecutive even positive integers are 26 and 28.

The length of the rectangle will be 34 yards.

The space occupied by any two-dimensional figure in a plane is called the area. The two-dimensional space occupied by the rectangle is called the area of the rectangle.

Given that A rectangle has a length of 32 yards less than 3 times its width. If the area of the rectangle is 748 square yards. The length and the width will be calculated by forming an expression.

Area = L x W

Area = W ( 3W - 32 )

748 = 3W² - 32W

3W² -32W -748 = 0

W = 22 and W = -11

The width will be 22 yards put W in the expression of L to get L.

L= ( 3W - 32 )

L = ( 3 x 22 - 32 ) = 34 yards

Therefore, the length of the rectangle will be 34 yards.

To determine the number of rows in the theater, we use the given information to create the equation x * (x - 7) = 144 where x is the number of seats per row. Factoring out, we find 16 and 9 as a suitable pair, leading to the conclusion that there are 9 rows of seats in the theater.

The student's question involves finding the number of rows of seats in a theater given certain constraints. To solve this problem, let's designate x as the number of seats in each row. According to the question, the number of rows of seats is 7 less than the number of seats in a row, which can be written as x - 7. Since we know the theater can seat 144 people in total, we can create the following equation to represent the total number of seats:

x  imes (x - 7) = 144

Solving this quadratic equation by factoring will give us the value of x, which will then allow us to calculate x - 7 for the number of rows. By factoring 144, we find that 16 and 9 are factors that satisfy the equation (16  imes 9 = 144) and also meet the condition that one factor is 7 less than the other (16 - 7 = 9). Therefore, the number of seats in each row is 16, and the number of rows is 16 - 7 which gives us 9 rows in the theater.

Answer:

The length is [tex]8[/tex] feet.

Step-by-step explanation:

we know that

the area of the rectangle is equal to

[tex]A=xy[/tex]

where

x is the length side of rectangle

y is the width side of rectangle

In this problem we have

[tex]A=48\ ft^{2}[/tex]

so

[tex]48=xy[/tex] ----> equation A

[tex]y=x-2[/tex] ------> equation B

substitute equation B in equation A

[tex]48=x(x-2)[/tex]

[tex]x^{2}-2x-48=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]x^{2}-2x-48=0[/tex]

so

[tex]a=1\\b=-2\\c=-48[/tex]

substitute in the formula

[tex]x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-48)}} {2(1)}[/tex]

[tex]x=\frac{2(+/-)\sqrt{4+192}} {2}[/tex]

[tex]x=\frac{2(+/-)14} {2}[/tex]

[tex]x=\frac{2+14} {2}=8\ ft[/tex]  -----> the solution

[tex]x=\frac{2-14} {2}=-6[/tex]

The probability that a randomly selected single parent in the U.S. military is a woman in the Air Force is [tex]\( \frac{6}{97} \)[/tex], which is approximately 0.0619 or 6.19%.

To find the probability that a randomly selected single parent in the U.S. military is a woman in the Air Force, we need to divide the number of women in the Air Force by the total number of single parents in the military.

1. First, find the number of women in the Air Force from the table. This is given as 6 thousand.

2. Next, find the total number of single parents in the military. This is given as 97 thousand.

3. Finally, divide the number of women in the Air Force by the total number of single parents in the military and express the result as a fraction or decimal to represent the probability.

So, the probability P can be calculated as:

[tex]\[ P = \frac{{\text{Number of women in the Air Force}}}{{\text{Total number of single parents}}} \][/tex]

Substituting the values:

[tex]\[ P = \frac{6}{97} \][/tex]

[tex]\[ P ≈ 0.0619 \][/tex]

Therefore, the probability that a randomly selected single parent in the U.S. military is a woman in the Air Force is approximately 0.0619 or 6.19%.

Complete question:

This problem involves empirical probability. The table shows the breakdown of 97 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is a woman in the Air Force.
