What is the arithmetic operation?
The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.
It took 10 brick masons 300 hours to brick a new home.
1 brick mason will take 300*10 =3000 hours
So 25 brick masons will take 3000/25 = 120 hours.

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.
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

The sum of the infinite geometric progression is S = ( 64/7 )
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the sum of the geometric progression be represented as S
Now , the equation will be
S = 16 , -12 , 9 , -( 27/4 ) ...
The sum of the infinite GP is S = a / ( 1 - r ) , where r is the common ratio
Substituting the values in the equation , we get
a₁ = 16
a₂ = -12
So , the common ratio r = a₂ / a₁
The common ratio r = -3/4
Substituting the values in the equation , we get
The sum of the infinite GP is S = a / ( 1 - r )
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 )
The sum of the infinite GP is S = ( 16 x 4 ) / 7
The sum of the infinite GP is S = ( 64/7 )

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 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.
How can you tell if a perspective is supplemental or complementary?Complementary angles are two angles with a combined angle of 90 degrees, whereas supplementary angles have a combined angle of 180 degrees.
What is the name for a 270 degree angle?Reflex angles are those that are larger than 180 degrees and less than 360 degrees. So 270 degrees is a reflex angle.

while looking at some reports, a store manager notes that sweaters that retail for $10 end up costing customers %10.90 once the sales tax is added. what is the sales tax percentage?
Let's call the sales tax rate as t (in decimal form).
The cost of a $10 sweater with the sales tax included is $10 + $10 * t = $10.90.
We can set up an equation to solve for t:
$10 * t = $0.90
Dividing both sides by $10:
t = 0.09
So the sales tax rate is 0.09, which is equivalent to 9%.

Standard formThe standard form of a linear equation is ...
ax +by = c
where a, b, c are mutually prime integers with a ≥ 0. If a=0, then b > 0.

A new spending tax of 25 percent is imposed on electrical goods. A shop decides to reduce all of its electrical goods in a sale. What percentage reduction is needed to restore all prices to their pre-tax values?
Consider what happens to the price of an item that costs £100 before the tax is imposed.
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.
what is percentage ?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%.
