Question
The product of two consecutive positive integers is 42. Find the integers.

Answers

Answer 1
Answer: 6 and 7

Let x be the first integer.
Let (x + 1) be the next, consecutive integer.
Let P be the product.
P = x(x+1)
42 = x(x+1)
42 = x^2 + 1x
0 = x^2 + 1x -42
-6 times 7 = -42
-6 + 7 = 1
0 = (x + 7)(x -6)
x = -7 (inadmissible, integer has to be positive)
x = 6 (zero principle)
Next consecutive integer: 6 + 1 = 7
The integers are 6 and 7!

The sum of the arithmetic sequence is S = 207 and the summation notation is S = ∑i=1 to 6 ( 5n + 17 )

What is Arithmetic Progression?

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the arithmetic sequence be represented as A

Now , the value of A is

A = 22 + 27 + 32 + 37 + 42 + 47

The number of terms n = 6

So , the value of i ranges from 1 to 6

Now , the summation is represented as ∑i=1 to 6 ( 5n + 17)

when n = 1

S₁ = 5 ( 1 ) + 17 = 22

when n = 2

S₂ = 22 + 5 ( 2 ) + 17

S₂ = 22 + 27

when n = 3

S₃ = 22 + 27 + 5 ( 3 ) + 17

S₃ = 22 + 27 + 32

Hence , the sum of the arithmetic sequence is S = 207

What is a number line?

A number line is a visual representation of real numbers on a straight line. It is used to graphically illustrate the relative position and size of numbers, and to perform operations like addition, subtraction, and comparison. The number line starts at a certain minimum value, and each point on the line represents a specific real number. The numbers increase as one moves to the right on the line, and decrease as one moves to the left. A number line is often used in mathematics education to help students understand basic concepts of numbers and operations.

The length of a rectangle is 2 meters less than twice its width. If the
perimeter of the rectangle is 92 meters, find the measure of the length and width
of the rectangle.

Answers

In the rectangle, the measure of the length is 30 meter and width is 16 meter,

.

What is a rectangle?

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. The length and breadth are the two dimensions that define a rectangle. The rectangle's longer side is its length, while its shorter side is its breadth.

Let the width of the rectangle is x meter, than the length of the rectangle is 2x-2.

Perimeter of rectangle = 2*(length + width)

⇒ 92 = 2*(2x-2 + x)

⇒ 92 = 2*(3x-2)

⇒ 92 = 6x - 4

add 4 in both side

⇒ 92 + 4 = 6x

⇒ 96 = 6x

divide oth side by 6

⇒ x = 96/6

⇒ x = 16

So the width of rectangle is 16 meter

The length of the rectangle = 2x-2

⇒ The length of the rectangle = 2*16-2

⇒ The length of the rectangle = 32-2

⇒ The length of the rectangle is 30

Solve the inequality 1/4b−1/5b>3/10b−1/2 and write the solution in interval notation.

Answers

Answer: To solve the inequality 1/4b−1/5b > 3/10b−1/2, we need to simplify both sides:

1/4b - 1/5b > 3/10b - 1/2

5/20b > 7/20b

Then we isolate b by subtracting 7/20b from both sides:

-2/20b > -7/20

Finally, we divide both sides by -2/20 to get:

b < 35/2

Lynne needs to borrow $5250 for cosmetic surgery. She obtains a loan from her grandmother for 24 months at a simple interest rate of 5.3%. What is the loans future value?
I need the formula explained as well​

Answers

The future value of the loan is $5807.65.

What do you mean by Interest?

It is expressed as a percentage of the amount borrowed and is paid over a specific period of time. The interest rate represents the cost of borrowing money and is one of the key factors in determining the overall cost of a loan. Interest is usually calculated on a yearly basis and can be compounded, meaning that the interest earned on a loan is added to the original principal and the interest rate is then applied to the new, higher amount. This process continues over time, leading to the growth of the original loan amount. The purpose of charging interest is to compensate the lender for the risk they are taking in lending the money and for the opportunity cost of not being able to invest the money elsewhere.

The future value of a loan is equal to the present value plus the interest earned over a specified time period. The formula to calculate the future value of a loan with simple interest is:

FV = PV (1 + rt)

where:

PV is the present value of the loan, which is $5250

r is the interest rate as a decimal, which is 5.3% ÷ 100 = 0.053

t is the time period in years, which is 24 months ÷ 12 months/year = 2 years

Substituting the values into the formula, we get:

FV = $5250 (1 + 0.053 * 2)

FV = $5250 (1.106)

FV = $5807.65

So, the future value of the loan is $5807.65. This is the amount Lynne will have to repay to her grandmother after 24 months, including the interest earned.

Answers

Maureen's pension would be $50,035.20.

What is Percentage?

To compute a percentage, divide the value by the entire amount and multiply the result by 100. A percentage is a quantity or ratio that is stated as a fraction of one hundred. The percent sign, "%," is frequently used to represent it.

First, we need to calculate the average of Maureen's three highest salaries:

Average = (107,000 + 107,800 + 108,198) / 3

Average = 322,998 / 3

Average = 107,666

Next, we need to calculate 1.56% of this average:

Percentage = 1.56% * 107,666

Percentage = 1,667.84

Finally, we multiply this percentage by the number of years worked to find the pension:

Pension = 30 * 1,667.84

Pension = 50,035.20

So, Maureen's pension would be $50,035.20.

seconds. Who would win a 400m dash, and by how much time?

Answers

The person who would win the dash is Mansoor by 4.26 seconds.

Who would win the race?

The first step is to determine the average speed of each of them. Average speed is the total distance travelled per time.

Average speed = total distance / total time

Average speed of Mansoor = 100 / 7.6 = 13.16 meters / second

Average speed of Saif = 30 / 2.6 = 11.54 meters / second

Mansoor is faster because he covers more meters in one second.

Time it would take to compete the dash = total distance / average speed

Time it would take Mansoor to complete the dash = 400 / 13.16 = 30.40 seconds

Time it would take Saif to complete the dash = 400 / 11.54 = 34.66 seconds

Hot dogs come in packs of 8. While buns come in packs of twelve. What is the least number of packs you should buy in order to have the same number of hot dogs and buns?

Answers

On solving the provided question, we can say that, by Least Common Multiple the amount to buy - 4 packs of buns and 5 packs of hot dogs.

What is least common multiple?

The smallest positive integer that is divisible by both a and b is known as the least common multiple, also known as the least common multiple, or the least common multiple of two numbers a and b. Least Common Multiple is referred to as LCM. The least frequent multiple of two numbers is also the least frequent multiple of both. A number and an integer are combined to create a multiple of that number. For instance, 10 is a multiple of 5, as 10 can be divided by 5, 2, and 5, making it a multiple of 5. The smallest positive integer that can be divided by both 5 and 2 is 10, making it the lowest common multiple of these numbers.

Least Common Multiple (LCM) between 10 and 8 is =  40

Buns is = 10-20-30-40

Hot dogs is =  8-16-24-32-40
