Cari is searching online for airline tickets. Two weeks​ ago, the cost to fly from boston to denver was ​$220. Now the cost is ​$295. What is the percent​ increase? What would be the percent increase if the airline charges an additional​ $50 baggage fee with the new ticket​ price?

Answers

The percent increase with the additional baggage fee for airline would be $125 / $220 x 100% = 56.82%.

What is meant by the term percentage?

A number can be expressed as a fraction of 100 using a percentage. It may be computed by dividing the number by the total and multiplying by 100. It is commonly represented by the sign "%". The percentage of men, for instance, would be 25/100 x 100, or 25%, if there were 100 persons in all.

In a variety of areas, including statistics, finance, and education, percentages are often employed. For instance, in finance, percentage increase in stock prices are used to gauge a market's or company's success. In education, grades are frequently given as percentages to represent class marks.

How to solve?

The increase in the cost of the ticket is $295 - $220 = $75

The percent increase is $75 / $220 x 100% = 34.09%.

If the airline charges an additional $50 baggage fee, the new ticket price would be $295 + $50 = $345.

The increase in the cost of the ticket with the additional baggage fee would be $345 - $220 = $125.

The percent increase with the additional baggage fee would be $125 / $220 x 100% = 56.82%.

10/8 = n/10 proportions please

Answers

Answer:

[tex]\displaystyle n=\frac{25}{2}[/tex]

Step-by-step explanation:

A proportion is a set of equal ratios.

Cross Multiplication

The most common (and easiest) way to solve a proportion is cross multiplication. To cross-multiply, multiply the numerators by the opposite denominators. So, you are multiplying across the proportion.

After cross multiplying you get 10*10 = 8n.

Solving For n

Now, we can use algebra to find n.

100 = 8n

Just, divide both sides by 8.

[tex]n=\frac{100}{8}[/tex]

Then, simplify.

[tex]n=\frac{25}{2}[/tex]

Checking The Answer

To check your answer all you have to do is plug n back into the equation.

[tex]\frac{10}{8}=\frac{25/2}{10}[/tex]

This can be rewritten as

[tex]\frac{10}{8}= \frac{25}{2} *\frac{1}{10}[/tex]

Then, the right side can be solved.

[tex]\frac{10}{8}= \frac{10}{8}[/tex]

Notice that the order the numbers are written on both sides is the same:

Because the order is the same and all that changed were the parentheses (the way the numbers were grouped), this is the associative property of addition.

The perimeter of a rectangle is 34 centimeters. The length is two more than twice the width. Find the length and the width of the rectangle.

Answers

The length of a rectangle is 12 units and width is 5 units.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

To determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given that the Perimeter of a rectangle = 34 cm.

and, length is two more than twice the width.

Thus the width be x.

So, the length = 2x + 2

So,

Perimeter of rectangle = 2 ( l +w )

34 = 2( x+ 2x+ 2)

17 = 3x +2

3x = 15

x= 5

2(5)+2 = 12

So, The length is 12 units and width is 5 units.

What is meant by a function?

A function from a set X to a set Y in mathematics assigns to each element of X exactly one element of Y. The domain of the function is the set X, and the codomain of the function is the set Y.

The first known attempt to define function can be found in the writings of Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. The concept of a function was codified in terms of set theory at the end of the nineteenth century, which substantially expanded its realms of applicability.

Greg works two part time jobs. One job is at a gas station that pays $12 an hour and the other is delivering groceries for $15.50 an hour. Between the two jobs Greg wants to earn at least $390 a week. Let x be the number of hours he works at the gas station and let y be the number of hours he works delivering groceries. Write an inequality that models this situation.

Answers

The required inequality model for this situation is 12x + 15.5y ≥ 390.

What are inequalities?

The mathematical expressions with inequalities are those with unequal sides on both sides. Unlike equations, we compare two values when we work with inequality. The equal sign is substituted between by the less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

"A connection is termed an inequality if two real numbers or algebraic expressions are connected by the symbols ">,"< "," <="," or ">=."

For instance, x>3 (x should be greater than 3)

If there is just one variable, the inequality is said to have an open sentence.

Instance: x 6 (x is less than 6)

Double Inequalities: If the statement demonstrates a double relation between the expressions or the numbers, the inequality is said to be a double inequality.

Instance: 3 x 8 ( x is greater than or equal to 3 and less than 8)
Given, the gas station pays $12 an hour and delivers groceries for $15.50 an hour.

And, x be the number of hours he works at the gas station and let y be the number of hours he works delivering groceries.

Then, total earnings in gas station = 12x

total earnings for delivering groceries = 15.5y

So, based on the given inequality condition

12x + 15.5y ≥ 390

Hence, the required inequality model for this situation is 12x + 15.5y ≥ 390.
