The length of the longest side of the isosceles triangle is 5 inches.

An isosceles triangle is a type of triangle in which two sides have the same length. The two equal sides are called the legs, and the third side, which is the base, is called the hypotenuse. The angle between the legs is called the vertex angle.

An isosceles triangle can be acute, meaning that the vertex angle is less than 90 degrees, right, meaning that the vertex angle is exactly 90 degrees, or obtuse, meaning that the vertex angle is greater than 90 degrees.

It's important to note that all equilateral triangles are isosceles but not all isosceles triangles are equilateral.

Given,

The length of the rod is 13 inches.

The length of the sides are x, x-1 and x-1.

We know that,

The rod length is 13 inches the mean perimeter is 13 inches.

So,

x + x-1 + x-1 = 13

=> 3x- 2 = 13

=> 3x= 15

=> x= 5 inches

Therefore, the other two sides = x-1 = 5-1 = 4 inches

So the length of the longest side of the isosceles triangle is 5 inches.

Step-by-step explanation:

The total area of metal that can be seen on the surface of the wood is 43.2 square millimeters.

To find the total area of metal that can be seen on the surface of the wood, we need to find the area of one nail head and then multiply that by the number of nails.

The area of a circle is given by the formula:

A = πr²,

where π is the mathematical constant pi (estimated as 3 in this case) and r is the radius of the circle (half of the diameter).

So, the area of one nail head in square millimeters is:

A = 3 ×(2.4/2)² = 3 × 1.2² = 3 × 1.44 = 4.32 square millimeters

As there are 10 nails, so the total area of metal that can be seen on the surface of the wood in square millimeters is:

Total area = 4.32 square millimeters/nail × 10 nails = 43.2 square millimeters

One of the four fundamental operations of mathematics is addition, which is typically denoted by the plus sign (+). The other three are subtraction, multiplication, and division. The entire amount or sum of the two whole numbers is obtained by adding them. Three apples and two apples are combined to make five apples in the example in the adjacent image. This observation is analogous to the formula "3 + 2 = 5" in mathematics (that is, "3 plus 2 is equal to 5").

In addition to counting things, addition can also be defined and performed using abstractions known as numbers, such as integers, real numbers, and complex numbers. A branch of mathematics called arithmetic includes addition. Addition can also be done on abstract objects like vectors, matrices, subspaces, and subgroups in algebra, another branch of mathematics.

There are three important steps to graph a line when an equation is given to us.

Let us look at an example for the same.

Let us graph the equation 6x + 2y = 12

Finding the x-intercept (the x-intercept has a y-value of 0),

6x + 0 = 12

⇒ x = 2

Hence, x-intercept is (2,0)

Finding the y-intercept (the y-intercept has an x-value of 0),

0 + 2y = 12

⇒ y = 6

Hence, y-intercept = (0,6).

We can set up the equation to represent the total cost of all the t-shirts and the money Antionette has ,

(x6.25) + (454.50) = 550

To solve for x, we can simplify the equation by multiplying the number of adult-sized t-shirts by the cost per t-shirt and the number of youth-sized t-shirts by the cost per t-shirt, and then set it equal to the total money Antionette has ,

x*6.25 + 202.5 = 550

then we can subtract 202.5 from both sides , x*6.25 = 347.5

then divide both sides by 6.25 to get ,  x = 56

The logarithmic function is a mathematical function that expresses the exponent of a number to produce a given value, with the property of simplifying multiplication to addition and it is the inverse of the exponential function.

A logarithmic function is a mathematical function that expresses the power to which a number (the base) must be raised in order to produce a given value. The logarithm of a number is the exponent to which the base must be raised to produce that number.

A logarithmic function can be represented in the form of log_b(x) or logb(x), where b is the base of the logarithm and x is the value being evaluated.

For example, the logarithm of 1000 to the base 10 is 3, because 10^3 = 1000. It can be written as log10(1000) = 3.

The logarithm function has the property that log_b(x*y) = log_b(x) + log_b(y), which means that logarithms simplify the multiplication of numbers to the addition of logarithms.

The logarithmic function also has an inverse function, which is the exponential function, that's why logarithms and exponents are inverses of each other.

For the linear equation 12 = 2x+4y, the value of ordered pairs are (0,3) and (6,0).

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The given linear equation is 12 = 2x + 4y

Substitute the value of x as 0 to find the value of y -

12 = 2x + 4y

12 = 2(0) + 4y

12 = 4y

y = 12/4

y = 3

Therefore, the value for y is obtained as 3.

Substitute the value of y as 0 to find the value of x -

12 = 2x + 4y

12 = 2x + 4(0)

12 = 2x

x = 12/2

x = 6

Therefore, the value for x is obtained as 6.

Your normal hourly rate is $40.50 and you earned $612.50 for working 46 hours this week, which is 1.5 times your normal hourly rate for each hour over 40.

Your normal hourly rate is the amount of money you get paid per hour for working. The overtime rate is For every hour you work over 40 in a week, your hourly wage will increase by 1.5.This means that if you work 46 hours in a week and your normal hourly rate is $40.50, you would receive $40.50 for each hour up to 40 hours, and then an additional $60.75 for each hour after that. This means that you would have earned a total of $612.50 for working 46 hours this week, with $405 for 40 hours and $207.50 for the 6 hours of overtime.

Normal hourly rate (40 hours) = 40 hours x $40.50/hour = $1,620

Overtime rate (6 hours) = 6 hours x $60.75/hour = $364.50

By applying discounted price concept, the original cost of the jersey can be determined from this equation 83.39 = 37.89 + 0.70x. The original cost of the jersey is $65.

Discounted price is a price obtained after a reduction by a certain percentage from the normal price. Thus, a discounted price is lower than the normal price.

The formula: discounted price = original price × (100% - %discount)

Some information given from the problem:

Jersey discount = 30%

Hat cost = $37.89

Total spent = $83.39

Let's say the cost of the jersey = x

Total spent = hat cost + discounted jersey cost

        83.39 = 37.89 + (x * (100% - 30%))

        83.39 = 37.89 + (x * (70%))

        83.39 = 37.89 + (x * 0.7)

        83.39 = 37.89 + 0.7x

Thus this is the equation.

If we want to know the original cost of the jersey, we can continue the calculation:

            83.39 = 37.89 + 0.7x

83.39 - 37.89 = 0.7x

              45.5 = 0.70x

                    x = 45.5/0.70
