If £1 is equal to 99.72 rupees and the post office only has 500 rupee papers how much can I change out of £450

The  equation which represents the amount is p = 0.0625 t.

When a consumer buys a good or service from a retailer, sales tax, which is estimated as a percentage, is added to the cost of the item.

Sales tax rate = sales tax percent / 100.

Sales tax = list price * sales tax rate.

Total price including tax = list price + sales tax,

Total price including tax = list price + (list price * sales tax rate),

Total price including tax = list price * ( 1 + sales tax rate)

We have been given

sales tax rate = 6.25%.

The price of the item = p

The sales tax = t

We know that the amount of sales tax paid on a purchase is proportional to the price of the item.

p = 6.25% t

p = 6.25/100 t

p = 0.0625 t.

Hence , P = 0.0625 t is the equation used to represent the amount.

No, the reasoning is not correct.

Step-by-step explanation:

39.99 x .14 = 5.5986  Does it make sense that the sales price plus the tax would be $5.60?  Doesn't that seem really low?

39.99 x .3  = 11.997 is the amount that we are taking off of the original price.

39.99 - 12 (Rounded to the nearest cent) is 27.99.

Now we pay the tax on the discounted amount of the item.

The equation of the line that is perpendicular to y = 2x + 3 and passes through the point (−4, 8) is y = - 1 / 2 x + 6(y equals negative one-half times x plus 6)

The equation of the line is perpendicular to y = 2x + 3 and passes through the point (−4, 8).

Therefore, perpendicular lines follows the rule:

m₁m₂ = -1

Hence,

2m₂= -1

m₂ = - 1 / 2

Therefore, let's find the slope of the line using (-4, 8)

8 = - 1 / 2 (-4) + b

Step-by-step explanation:

The simple interest of the sum at the same rate and time is 2400

The interest that is paid on the principal and interest at regular intervals is known as compound interest.The difference between compound interest and simple interest starts to show after the first year, though.Beginning with the second year, interest is computed on both the principal amount and the interest from the prior year. As a result, interest on interest is another name for it.

Given that : Sum =8000 and time = [tex]\frac{3}{2} years[/tex] and rate is 20 %

When rate is calculate half yearly

R becomes [tex]\frac{R}{2}[/tex]

T becomes 2T

A = [tex]P(1+\frac{R}{100} )^{T}[/tex]

C.I = A-P

R = [tex]\frac{20}{2} = 10%[/tex]%

T = 2× [tex]\frac{3}{2} years[/tex] = 3years

A = [tex]P(1+\frac{R}{100} )^{T}[/tex]

A = 8000[tex]\frac{11}{10} ^{3}[/tex]

A = 8 ×1331

A = 10648

Now ,

C.I = A - P

C.I =10648 - 8000

C.I = 2468

The compound interest is 2468

Simple interest

A = P(1+rt)

A = 8000(1+0.2×1.5)

A =10400

S.I =A- P

= 10400 - 8000

They way you can change the grouping of the addends. in $5.50+$7.83+$3.50 is;  $5.50 + ($7.83 + $3.50) =  ($5.50 + $3.50) + $7.83

There are different algebraic properties such as;

Commutative Property

Associative Property

Distributive Property

Now, the commutative property states that the change in the order of two numbers in an addition or multiplication operation does not change the sum or the product. For example;

a + b + c = c + a + b or a* b = b * a

Now, the associative property states that the way in which factors are grouped in a multiplication or addition problems does not change the product. For example; x + (y + z) = (x + z) + y

Now, to our question, one way to group the addends using associative property is;

Every radical can be rewritten has an exponent .

Extraneous Solutions occur because squaring both sides of a square root equation results in 2 solutions (the positive and negative number).

1. Exponents that are written as fractions are referred to as rational exponents.

The top of the rational exponent is the new exponent on the radical, and the bottom of the rational exponent is the root, therefore a rational power can be reinterpreted as a radical in this fashion.

2. Separate the radical expression from the equal sign on one side. Put every every clause over there on the other side. Square both sides of the equation if the radical is a square root. Raise both sides of the equation to the third power if it is a cube root. Write an expression as a radical if the expression has a logical exponent. By examining the exponent's numerator, you may determine the power. By examining the exponent's denominator, you can get the root. Raise the radicand to the power while using the base as the radicand, and use the root as the index.

3. Extraneous Solutions appear because there are two solutions when you square the two sides of a square root equation (the positive and negative number). As a result, one of those figures will represent an extra solution, or a solution that is added but does not satisfy the initial equation.

Using proportions, the number of planes in each city after 8 hours is given as follows:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division, with the given ratios.

One example of application of proportions is for percentage problems, as the total amounts are multiplied by the decimal equivalent of the percentage to find the equivalent amounts.

The planes in Los Angeles after 8 hours are given as follows:

Hence the amount is:

0.7 x 30 + 0.25 x 12 + 0.125 x 8 = 25.

The planes in St. Louis after 8 hours are given as follows:

A graph of the linear equation (2x - 4y = 0) is shown in the image attached below.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

Generally speaking, the graph of any proportional relationship such as a linear equation is characterized by a straight line because as the values on the x-axis increases or decreases, the values on the y-axis increases or decreases simultaneously as shown in the image attached below.

In conclusion, a graph which represents the linear equation (2x - 4y = 0) shows a proportional relationship between the value of x and y.

Here in this issue, we are managing linear equations which is a condition of one variable regularly composed within the form ax+b=0 , where a and b are real numbers and x is an unknown variable. Solutions to linear equations allude to a linear equation that can have zero, one, or infinitely various solutions. A linear equation with no solutions simplifies to an untrue statement such as 1=0. A linear equation with one solution rearranges to a solution of the form x=n where n may be a real number. A Linear equation with infinitely various solutions simplifies to a true statement without a variable such as 1=1.

Here we  considering  the rate of the slow hiker  to be x, so the rate for the fast hiker will be x+2.2

Since we know that  distance = speed * time

therefore, the Distance covered in 5 hours by a slow hiker is 5x , wheras for fast hiker it will be 5(x+2.2)=5x+11 km

As we are given the condition that it i they are  33 miles apart, So

=>5x + 5x+11 = 33

=>10x = 33-11

=>10x = 22

x =22/10 => 2.2
