Tyrese bought 35 tickets to use at a carnival. He used some of the tickets to ride the bumper cars and play some games. Now he has 28 tickets left. What is the percent of decrease in the number of tickets that he has?

Answers

Answer 1

The percent of decrease, in the number of tickets that he has, is 20%.

What is a percentage?

The term "percentage" refers to any ratio or number that may be expressed as a fraction of 100. And the sign "%" is used to denote it.

Given, Tyrese bought 35 tickets to use at a carnival.

He used some of the tickets to ride the bumper cars and play some games. Now he has 28 tickets left.

That means,

he used 35 - 28 = 7 tickets.

To find the percentage of decrease:

Let m be the percentage of decrease.

Then,

7 = m x 35 / 100

m = 700 / 35

m = 20

Therefore, the percentage of decrease is 20%

What is Solution set ?

A solution set in mathematics is the collection of values that satisfy a particular set of equations or inequalities. The set of solutions to a constrained optimization problem represents the viable zone.

We have, 8x + 5y ≤ 100

Let's assume it as 8x + 5y = 100,

when x = 0,

   5y = 100

    y = 20

when y = 0,

   8x = 100

    x = 12.5

So, The line touches x-axis and y-axis at 12.5 and 20.

Now, Putting (0, 0) in  8x + 5y ≤ 100,

What if limit is infinity minus infinity?

Answers

If the limit is infinity minus infinity it is undefined because the result would be a number that is not a real number.

In mathematics, a limit is the value that a function approaches as the independent variable approaches a certain value. Limits are used to study the behavior of a function as the independent variable approaches a certain point.When the limit is infinity minus infinity (∞ - ∞), it is undefined because the result is not a real number. Infinity minus infinity is an indeterminate form, which means that the limit could approach any real number or it could approach infinity or negative infinity. In other words, the result of infinity minus infinity is an unknown quantity.To understand why infinity minus infinity is undefined, you must understand the concept of infinity. Infinity is not a number, but rather an idea of something that is larger than any number. Therefore, when subtracting infinity from infinity, there is no set answer since the two concepts are not numbers. To calculate the limit, the two infinities must be replaced with real numbers. In conclusion, when the limit is infinity minus infinity, it is undefined because the result is not a real number. Infinity is an idea and not a number, so the result of infinity minus infinity can not be determined. To calculate the limit, the two infinities must be replaced with real numbers.

To represent such function graphically we use two perpendicular lines called axes and their point of intersection is called as the origin. This method of representation is known as the Cartesian coordinate system. The numerical value of one variable is measured along the horizontal axis called the x axis. Whereas the numerical value of the other variable is measured along the vertical axis called the y axis.

The four sections formed due to these axex are called quadrants.

Here, we have

A worker's earnings E are a function of the number of hours N worked at a rate of $8.75 per hour.

We have to create an incognita that represents a worker's salary based on how many hours he or she works.

A triangular pendant has two sides of length 23 mm and 31 mm. What are the possible lengths (in whole mm) for the third side?.

Answers

According to Pythagoras theorem, the value of the third side of the triangle is 38.6mm

In math Pythagoras theorem states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

Here we have given that the triangular pendant has two sides of length 23 mm and 31 mm.

And we need to find the possible lengths (in whole mm) for the third side.

Here in the given question, we have the values of the two sides are 23mm and 31mm.

Then we have to apply the values on the Pythagoras theorem formula,

=> hypotenuse² = adjacent² + opposite²

Now, we have to apply the values as opposite and adjacent on it, then we get,

=> hypotenuse²= 23² + 31²

=> hypotenuse² = 529 + 961

=> hypotenuse² = 1490

Therefore, the value of the third side is 38.6mm

The four Inverse operations are :

What are inverse Operation ?

Inverse operations, such as addition and subtraction, multiplication and division, are pairs of mathematical operations where one operation reverses the effect of the other. In most cases, a number's inverse refers to its reciprocal, as in x /1 Equals 1 / x. One results from multiplying a number by its reciprocal, or inverse.

To produce a result equal to 0, add the original number and the additive inverse by simply reversing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.

A multiplicative inverse or reciprocal for a number x is a number that, when multiplied by x, produces the multiplicative identity, or 1. It is represented by 1/x or x/1. A fraction a/b has a multiplicative inverse of b/a. Divide 1 by the real number to obtain the multiplicative inverse of the number.

Squares are the numbers that are produced when a value is multiplied by itself. In contrast, a number's square root is a value that, when multiplied by itself, returns the original value.

The definition of a cube is the process of multiplying a number by itself three times, while a cube root is the opposite of a cube. Alternately, we may state that a number's cube root gives us a number that, when cubed, gives us the same number and is referred to as a perfect cube.

At which root does the graph of f x x 4 6 * x 7 5 cross the X axis?

Answers

The graph of the function f(x) = x^4 - 6*x^7 + 5 crosses the x-axis at x = 0 and x = 5.

The graph of the function f(x) = x^4 - 6*x^7 + 5 is a polynomial function. The roots of a polynomial are the values of x for which the polynomial is equal to zero. To find the roots of the polynomial, we must solve the equation f(x) = 0. To solve this equation, we will use polynomial division.

We will divide the polynomial by (x - 5), which will give us the following result:

f(x) = x^4 - 6*x^7 + 5 = (x - 5)(x^3 + 7x^2 - 5x + 25).

We can now solve for the roots of the polynomial. Since (x - 5) is a factor of the polynomial, the root is x = 5. We can also solve for the other roots by setting the remainder of the polynomial division equal to 0. This gives us the equation x^3 + 7x^2 - 5x + 25 = 0. This equation can be solved by factoring and the result is x = 0, 1, and 5. Therefore, the graph of f(x) = x^4 - 6*x^7 + 5 crosses the x-axis at x = 0 and x = 5.

f(x) = x^4 - 6*x^7 + 5

Divide f(x) by (x-5):

f(x) = (x-5)*(x^3 + 7x^2 - 5x + 25)

Set remainder equal to 0:

x^3 + 7x^2 - 5x + 25 = 0

Answers

Answer:

A could finish the whole work in 60 days

Step-by-step explanation:

Both A and B can finish the work in 30 days.

That means both A and B can finish 1/30 part of the work in 1 day.

So in 20 days, both A and B can finish 20/30 = 2/3 part of the work.

Both A and B worked together for 20 days and completed 2/3 part of the work. Now 1/3 part of the work is remaining.

But after 20 days B left the work. Now A finished the remaining 1/3 part of the work alone.

Given A has completed the remaining 1/3 part of the work in 20 days. We are asked to find in how many days A could finish the whole work.

Let A could finish the whole work in x days.

That means A could finish 1/x part of the work in 1 day.

So in 20 days, A could finish 20(1/x) = 20/x part of the work.

But it's given that A finished the remaining 1/3 part of the work in 20 days.

Thus we are able to equate 20/x and 1/3.
