The simplified form of the expression is y - 1.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is (1 - [tex]\frac{1}{y}[/tex] ) / [tex]\frac{1}{y}[/tex]
The numerator of the expression can be written as below using the cross multiplication process.
1 - [tex]\frac{1}{y}[/tex] = (y - 1) / y
The whole expression becomes,
(1 - [tex]\frac{1}{y}[/tex] ) / [tex]\frac{1}{y}[/tex] = [(y - 1) / y] / [tex]\frac{1}{y}[/tex]
= (y - 1) / 1
= y - 1
Hence the simplified form is y - 1.

nine lines are drawn in a plane. what is the largest possible number of intersections in the plane which at least two of the nine lines intersect
The largest possible number of intersections in a plane with 9 lines is 36, which is achieved when each line intersects with every other line.
The largest possible number of intersections in the plane where at least two of the nine lines intersect is 36. To see why this is the case, consider a construction where each of the nine lines intersects with every other line. In this construction, each line intersects with eight other lines, so the total number of intersections is 9 * 8 / 2 = 36. This construction is possible to achieve in a plane, so 36 is the largest possible number of intersections.
This result can be explained using the formula for counting the number of intersections in a set of n lines. If each line intersects with every other line in the set, the total number of intersections will be equal to n choose 2, or n(n-1)/2, where n is the number of lines. In this case, n=9, so the maximum number of intersections is 9 choose 2 = 9(9-1)/2 = 36.
It is important to note that not all sets of nine lines in a plane will have 36 intersections. The actual number of intersections will depend on the specific configuration of the lines. However, 36 is the largest possible number of intersections for a set of nine lines in a plane.

Solve for the value of pp (3p+6)° (4p+7)°
The value of the equation 6 + 3p = 4p + 7 is 1
How to solve the equation?Reorder the terms:
6 + 3p = 7 + 4p
Solving for the value of p by collecting like terms
6 + 3p = 7 + 4p
Move all terms containing p to the left, all other terms to the right.
Add '-4p' to each side of the equation.
-6 + 3p + -4p = -7 + 4p + -4p
Combine like terms: 3p + -4p = -1p
-6 + -1p = -7 + 4p + -4p
Combine like terms: 4p + -4p = 0
-6 + -1p = -7 + 0
-6 + -1p = -7
Add '6' to each side of the equation.
-6 + 6 + -1p = -7 + 6
Combine like terms: -6 + 6 = 0
0 + -1p = -7 + 6
-1p = -7 + 6

The difference in the area of the square 'a' and 'b' as per given side-length is equal to 8 ( x + 1 ) square meters.
Side length of square 'a' = (2x + 1) meters
Side length of square 'b' = ( 2x + 1 + 2 ) meters
= ( 2x + 3 ) meters
Area of a square 'a' = ( side length )²
= ( 2x + 1 )²
Area of a square 'b' = ( side length )²
= ( 2x +3 )²
Difference in the area of the squares = ( 2x +3 )² - ( 2x +1 )²
= ( 2x + 3 -2x -1 )( 2x + 3 + 2x + 1 )

on a map 1 inch represents 5 miles. if a certain state is represented on a map by a rectangle 10 inches by 7.2 inches, what is the area of the state in square miles
The area of the state in square miles is 72 x 5 = 360 square miles.
The formula to calculate the area of a rectangle is A = l x w, where 'A' is the area, and 'l' and 'w' are the length and width respectively.
Therefore, the area of the state that is represented on a map by a rectangle 10 inches by 7.2 inches, is calculated by substituting the length and width into the equation, as follows: A = 10 x 7.2 = 72 inches.
Since 1 inch represents 5 miles, the area of the state in square miles is calculated by multiplying the area (in inches) by the conversion factor (5 miles per inch). Therefore, the area of the state in square miles is 72 x 5 = 360 square miles.

The expression which represents the amount Rita spent at the mall is 18.82d + 42. If d = 6, then the total amount spent is $154.92.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Amount spent at one store is given by the expression 18.82d + 22.
Here d is the number of items she bought at that store.
Amount spent at another store = $20
Total amount spent at the mall = 18.82d + 22 + 20 = 18.82d + 42.
If she bought 6 items, d = 6.
Total amount spent = (18.82 × 6) + 42 = $154.92

consider an experiment to investigate the effectiveness of different insecticides in controlling pests and their impact on the productivity of tomato plants. what is the best reason for randomly assigning treatments (spraying or not spraying) to the farms?
Randomly assigning treatments to the farms is the best way to ensure that the results of the experiment are valid, unbiased, and accurate.
Random assignment of treatments is the best way to ensure that the results of the experiment are valid and not biased. Random assignment of treatments would ensure that the results are not affected by factors such as soil type, climate, and other environmental conditions. This is because random assignment of treatments would ensure that the farms that receive the insecticide treatment are not systematically different from those that do not receive the treatment. This is important in order to gain accurate results from the experiment.
Random assignment of treatments is accomplished using the following formula:
Treatment Assignment = (Number of Farms) x (Random Number between 0 and 1)
By randomly assigning treatments to the farms, we can be sure that the results are not skewed by external factors. This will allow us to better determine the effectiveness of different insecticides in controlling pests and their impact on the productivity of tomato plants.

What is imaginary number?The complex numbers that are not real are represented by the fictitious unit "i." However, in order to convert complex numbers into their whole real form, we must first determine what the value of the fictitious number i is √-1.
Essentially, it was once thought that there was no difference between real and imaginary numbers in fact. Real numbers and fictitious numbers, however, were distinguished when the complex number entered the scene.
The quadratic formula is given as:
x = -b ± √ b² - 4ac ÷ 2a
In the given equation:
8x^2-4x+2=0
b = -4, a = 8, and c = 2
Substituting the value in the quadratic equation formula we have:
x = -(-4) ± √(-4)² - 4(8)(2) ÷ 2(8)
x = 4 ± √16 - 64 ÷ 16
x = 4 ± √-48 ÷ 16
The negative sign can be replaced by imaginary number (i)^2 hence:
x = 4 ± √48(i)² ÷ 16
x = 4 + 6.9i ÷ 16 and x = 4 - 6.9i ÷ 16

The diagonal of a tv screen is 26 inches. the base is 18.8 inches wide. how tall is the tv?
the height of the triangle formed by the diagonal and base of the TV screen.
The height of the TV is approximately 15.6 inches.
(26 inches / √2) = 18.8 inches
(18.8 inches * √2) = 26 inches
Height = (26 inches / 18.8 inches) * 18.8 inches
Height = 15.6 inches
Step 1: Calculate the hypotenuse of the triangle formed by the diagonal and base of the TV screen.
Hypotenuse = diagonal / √2
Hypotenuse = 26 inches / √2
Hypotenuse = 18.8 inches
Step 2: Calculate the diagonal of the triangle formed by the hypotenuse and base of the TV screen.
Diagonal = hypotenuse * √2
Diagonal = 18.8 inches * √2
Diagonal = 26 inches
