The total cost of the deal for the router for Tina is given by A = $ 1059.81

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the total cost of the deal be represented as A

Let the initial price of the router be = $ 39.99

Now , the percentage of discount for the router = 15 %

So , the final cost of the router = ( 85/100 ) x 39.99

On simplifying , we get

The final cost of the router = $ 33.9915

Now , the number of months = 18 months

The contract rate = $ 56.99 per month

So , the total contract rate for 18 months = 18 x 56.99

The total contract rate for 18 months = $ 1,025.82

Now , total cost of the deal A = final cost of the router + total contract rate for 18 months

On simplifying the equation , we get

The total cost of the deal A = $ 1,025.82 + $ 33.9915

The total cost of the deal A = $ 1059.8115

The total cost of the deal A = $ 1059.81

Hence , the total cost of the deal is $ 1059.81

The ratio for the area and the ratio for the circumferences of the circles are 9 : 1 and 6 : 1 respectively.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

If the radius of one circle is three times the radius of another circle, then we can use this information to determine the ratio of the areas of the circles and the ratio of the circumferences of the circles without knowing their actual measurements.

Let's call the radius of the smaller circle "r" and the radius of the larger circle "3r".

Ratio of areas -

The area of a circle is proportional to the square of its radius, so the ratio of the areas of the two circles is -

= (area of larger circle) / (area of smaller circle)

= (π(3r)²) / (πr²)

= 9r²/r²

= 9/1

Therefore, the ratio of the areas of the two circles is 9:1.

Ratio of circumferences -

The circumference of a circle is proportional to its radius, so the ratio of the circumferences of the two circles is -

= (circumference of larger circle) / (circumference of smaller circle)

= 2π(3r) / 2πr

= 6r/r

= 6/1

Therefore, the ratio of the circumferences of the two circles is 6:1.

From the given situation of equation Diamond worked 24 overtime hours that week.

The hourly rate that is paid for the typical hours worked within a pay period is known as regular pay. For full-time employees in the US, this is typically referred to as 40 hours a week. On the other hand, overtime pay is the hourly rate paid for any additional hours worked. Most businesses give time-and-a-half (1.5 times the usual pay rate) or double-time (two times the regular pay rate) for extra hours, which is often more than regular compensation.

Let us suppose the number of hours = x.

Let us suppose the overtime hours = y.

From the given situation we have:

7.5x + 11.25y = 352.5 (equation 1)

x + y = 35 (equation 2)

Substituting equation 2 into equation 1 and simplifying:

7.5x + 11.25(35 - x) = 352.5

7.5x + 393.75 - 11.25x = 352.5

-3.75x = -41.25

You should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.

An expression is a group of symbols and/or numbers used to represent a quantity or a mathematical relationship between two quantities in mathematics. Variables, constants, as well as operators like addition, subtraction, multiplication, and division, can all be found in an expression.

Since there are 4 quarts in a gallon, 1.5 quarts is equal to 1.5/4 = 0.375 gallons of gasoline.

To determine how much oil to add, we need to use the ratio of 2.4 fl. oz. of oil for every gallon of gasoline.

First, we need to convert the amount of gasoline we have from gallons to fluid ounces:

0.375 gallons x 128 fluid ounces per gallon = 48 fluid ounces of gasoline.

Next, we can use the ratio to find how much oil to add:

2.4 fl. oz. oil: 1 gallon gasoline

x fl. oz. oil: 48 fl. oz. gasoline

Cross-multiplying, we get:

2.4 x 48 = 1 x (x)

115.2 = x

The total cost of the shirt and three skirts before the coupon is:

$22.65 + 3($33.31) = $122.58

With the 10% discount, the total cost becomes:

$122.58 - 0.1($122.58) = $110.32

To find out how much change the cashier gave back to Mary, we need to subtract the total cost from the amount of money Mary's mom gave her:

$100.00 - $110.32 = -$10.32

Since the result is negative, it means Mary did not have enough money to pay for her purchases and would have to give the cashier an additional $10.32 to cover the full cost of her shopping.

If the original triangle has an area equal to 729 small dotty triangles. The original triangle has an area of 8 square units.

Let's first find the pattern of the number of small triangles in each row. The first row has 1 small triangle. The second row has 3 small triangles. The third row has 5 small triangles, and the fourth row has 7 small triangles. We can see that the pattern is that each row has 2 more small triangles than the previous row.

To find how many small triangles are in the third row, we add 2 to the number of small triangles in the second row:

3 + 2 = 5

So there are 5 small triangles in the third row.

To find how many small triangles are in the fourth row, we add 2 to the number of small triangles in the third row:

5 + 2 = 7

So there are 7 small triangles in the fourth row.

To find the total number of rows, we can count the number of rows from the top of the triangle to the bottom. Alternatively, we can use the formula for the sum of an arithmetic series to find the number of terms in the sequence. In this case, the first term is 1, the common difference is 2, and the last term is 7. Using the formula:

n = (last term - first term) / common difference + 1

n = (7 - 1) / 2 + 1

n = 4

So there are 4 rows in the triangle.

Finally, we can use the formula for the sum of an arithmetic series to find the total number of small triangles in the original triangle. In this case, the first term is 1, the common difference is 2, and the number of terms is 4. Using the formula:

sum = (n / 2) * (first term + last term)

sum = (4 / 2) * (1 + 7)

sum = 4 * 4

sum = 16

So there are 16 small triangles in the original triangle. Since each small triangle has an area of 1/2, the total area of the original triangle is:

area = 16 * (1/2)

area = 8

Therefore, the original triangle has an area of 8 square units.

A square, according to Euclidean mathematics, is a quadrilateral with four equal sides and four equal angles. Another term for a rectangle is a shape with two neighboring sides that are the same length. A quadrilateral is said to be equilateral if one of its 4 triangular edges and four equal corners is a square. A cubical angle refers to one that's 90 ° or straight. The square's diagonals are evenly spaced and split in half at a 90-degree angle.

Here,

We can use the formulas for area and perimeter of a square to decide which is greater: its area or perimeter with sides that are 10 units long.

A = s², where s is the extent of one edge, calculates the area of a square. The square's size in this instance is

=> 102 = 100 square units.

P = 4s, where s is the length of one edge, calculates the perimeter of a square. In this instance, the square's circumference is

=> 4(10)

The solution for the given system of equations is (1,0) using the addition method.

The addition method, also known as the elimination method, is a technique used to solve a system of linear equations by adding the two equations together in such a way that one of the variables is eliminated.

Multiply the first equation by -2:

-10x - 12y = -10

Add the second equation to the first:

-10x - 12y = -10

10x + 12y = 10

0 + 0 = 0

We can solve one of the original equations for x in terms of y and then replace into the equation to represent the solutions in terms of y. For instance, when we solve the first equation for x, we obtain:

5x + 6y = 5

5x = 5 - 6y

x = (5 - 6y)/5

By substituting this into the second equation, we get:

10x + 12y = 10

10((5 - 6y)/5) + 12y = 10

2(5 - 6y) + 12y = 10

10 - 4y = 10

-4y = 0

y = 0
