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.

2/3 + 2/3 = 4/6 = 2/3

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

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

Difference = 34.66 - 30.40 = 4.26 seconds

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

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

When a new spending tax of 25% is placed on electrical items, the price of a product that costs £100 before the tax is imposed is reduced to $25.

In economics, a percentage is a percentage or ratio that is specified as a fraction of 100. Occasionally, this same acronyms "percentage points.," "%," and "pm" are also used. But it is broadly classified into the following by the percent sign, "%." The % sum has no dimensions. Rates are effectively fractions when the sum is 100. Use the percent sign (%) to indicate that a number seems to be a fraction by placing it next to it. So instance, you score a 75% if you properly answer 75 out from 100 respondents on a test (75/100). Divide the money by the total as well as multiply it by 100 to calculate percentages. The formula used to calculate the percentage is (value/total) x 100%.

Answer:

x = 11

y = 21

Step-by-step explanation:

1. y = 2x-1

2. 6x-2y = 24

lets plug in the value of y from the first equation, into the second

6x - 2(2x-1) = 24

6x - 4x + 2 = 24

2x + 2 = 24

2x = 22

x = 11

lets plug in x to the first equation to find y

y = 2(11)-1

y = 22-1

y = 21

Answer:

x = 11

y = 21

Step-by-step explanation:

y = 2x - 1;

6x - 2y = 24

y = 2x - 1

3x - y = 12

y = 2x - 1

3x - (2x - 1) = 12

y = 2x - 1

x + 1 = 12

y = 2x - 1

x = 11

y = 2(11) - 1

x = 11

y = 21

x = 11

Answer:

A. 0.25

Step-by-step explanation:

The coefficient of friction can be calculated as follows:

friction coefficient = force of friction / force of weight

The force of friction is equal to the force applied to the book bag, which is 5 pounds, and the force of weight is equal to the weight of the book bag, which is 20 pounds.

friction coefficient = 5 / 20

friction coefficient = 1/4 or 0.25

So the coefficient of friction between the floor and the book bag is 0.25.

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:

The value of x is 30 degrees as it is a complimentary angle. When two angles' measurements add up to 90 degrees, they are said to be complimentary. When two angles' measures sum up to 180 degrees, they are said to be supplementary.

Complementary angles are two angles with a combined angle of 90 degrees, whereas supplementary angles have a combined angle of 180 degrees.

Reflex angles are those that are larger than 180 degrees and less than 360 degrees. So 270 degrees is a reflex angle.

Step-by-step explanation:

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

.

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

The sum of the infinite GP is S = 16 / ( 1 - ( -3/4 ) )

The sum of the infinite GP is S = 16 / ( 1 + 3/4 )

The sum of the infinite GP is S = 16 / ( 7/4 )
