Shirley/Tracey has to stay at least 10 days for the M and N to cost less

Answer:

10 days.

Step-by-step explanation:

Let d represent number of days.

We have been given that ABC Travel offers a plane ticket for $295 and a rental car for $39 per day. The total cost of travelling x days using ABC travel company would be [tex]39x+295[/tex].  

We have been given that M and N Travel offers a plane ticket for $350 and a rental car for $33 per day. The total cost of travelling x days using M and N travel company would be [tex]33x+350[/tex].

To make M and N travel the better deal, we will set an inequality, where total cost of x days using ABC travels is greater than M and N travels as:

[tex]39x+295>33x+350[/tex]

[tex]39x-33x+295>33x-33x+350[/tex]

[tex]6x+295>350[/tex]

[tex]6x+295-295>350-295[/tex]

[tex]6x>55[/tex]

[tex]\frac{6x}{6}>\frac{55}{6}[/tex]

[tex]x>9.166[/tex]

Since the closest integer to 9.1677 is 10, therefore, for a vacation of 10 days using M and N travels will be the better deal.

Answer:

B. √25 + 1.75

Step-by-step explanation:

A. π + 18 = 21.14159265..

B. √25 + 1.75 = 6.75

C. √3 + 5.5 = 7.2320508...

D. π + √2 = 4.55580..

Rational numbers are any fractions, integers, terminating decimals, or repeating decimals.

Option B will be a rational number while options A, C and D will be irrational numbers.

A number that can be written in p/q form where q≠0 is called a rational number.

An irrational number is non-terminating and non-repeating in nature.

For example, π is an irrational number because

π =3.1415926535897.....................that is non-terminating and non-repeating and can never be written in p/q form

Similarly, a non-perfect-square number written inside a root is also an example of an irrational number.

A)  π + 18

π is an irrational number while 18 is a rational number so the sum of irrational and rational will be an irrational number.

B) √25 + 1.75

√25 = 5 i.e. a rational number

1.75 is a rational number

Rational + Rational = Rational

5+1.75 = 6.75

6.75 is a rational number.

C) √3 + 5.5

√3 is an irrational number so √3 + 5.5 is an irrational number.

D) π + √2

π is an irrational number so π + √2 is an irrational number.

Hence, Option B will be a rational number while options A, C and D will be irrational numbers.

There are an infinite amount of numbers between 5 and 10 if you consider decimal positions.

However, if you're referring to whole numbers (example: 5, 25, 200, etc)

There are 4 numbers between 5 and 10:

6, 7, 8, and 9.

The answer would be -9/11 because since the denominator is the same, we can ignore it for now. Just add -4 and -5, you get -9. Finally, add the denominator of 11 back to get the answer

2/3x - 4 = -92

Add 4 to both sides.

2/3x = -88

Multiply both sides by 3.

2x = -264

Divide both sides by 2.

x = -132. (This is your answer.)

Let me know if you have any other questions! :)

To find the difference between two thirds of a number and 4, you can set up an equation and solve for the number.

To find the difference between two thirds of a number and 4, we can use algebraic expressions. Let's assume the number is x.

Two thirds of the number can be expressed as (2/3)x.

The difference between two thirds of the number and 4 can be written as (2/3)x - 4.

According to the problem, this expression is equal to -92. So we have the equation (2/3)x - 4 = -92. Solving this equation will give us the value of x, which is the number we are looking for.

$22.25 will be your answer for this one

Answer:

Your answer will be 22.25 because 0.89 times 25 equals that

Step-by-step explanation:

Answer: The values of the function V(x) over the domain (2, 5, 7) are 17881.66, 12,606.01 and 9985.224.

Explanation:

The cost of car is $22575 and the value of car depreciate at a rate of 11% per year.

The value of car can be modeled by the equation,

[tex]V(x)=22,575(0.89)^x[/tex]

Where is number of years after purchase of car or the age of car. We have to find the value of the function over the domain (2,5,7), so put x=2,

[tex]V(x)=22,575(0.89)^2=17881.66[/tex]

It means the value of car will be $17881.66 after two years.

put x=5,

[tex]V(x)=22,575(0.89)^5=12,606.01[/tex]

It means the value of car will be $12,606.01 after five years.

put x=7,

[tex]V(x)=22,575(0.89)^7=9985.224[/tex]

It means the value of car will be $9985.224 after seven years.

Answer:

x < -19/13

Step-by-step explanation:

The solution to the inequalities −9x+2>18 and 13x+15≤−4 is to find values of x that satisfy either x < ∘⅗⁄3 or x ≤ ∘⅗/13.

To solve the equations −9x+2>18 OR 13x+15≤−4, we need to treat them separately as two different inequalities.

For the first inequality, subtract 2 from both sides to get −9x > 16, then divide by −9 to isolate x, which gives us x < ∘⅓⁄9 or x < ∘⅗⁄3.

For the second inequality, subtract 15 from both sides to get 13x ≤ −4 − 15 or 13x ≤ −19. Finally, divide by 13 to isolate x, leading to x ≤ −⅓⁄13 or x ≤ ∘⅗/13.

Therefore, the solution to the system of inequalities is any x that satisfies at least one of these conditions: x < ∘⅗⁄3 or x ≤ ∘⅗/13.

Isolate the y. Note the equal sign. What you do to one side, you do to the other. Subtract 4.58 form both sides

4.58 (-4.58) + y = 2.5 (-4.58)

y = 2.5 - 4.58

y = -2.08

-2.08 is your answer

Answer:

The numbers are 1, 2 ,3, 4, 5 and 6.

Therefore 4 of the 6 numbers are greater than 2 so the probability is 4 out of 6 or 2/3.

Step-by-step explanation:

The question relates to probability while rolling a six-sided die for a number greater than 2. There are four favorable outcomes; 3, 4, 5, or 6. Therefore, the probability of this event is 4/6 or 2/3.

The question you asked pertains to the concept of probability, specifically within the context of a fair, six-sided die. In this experiment, there are 6 equally likely outcomes: 1, 2, 3, 4, 5, or 6. When asked for the probability of rolling a number greater than 2, the outcomes we consider favorable are 3, 4, 5, and 6. That's 4 favorable outcomes. So, to calculate the probability of this event, you must divide the number of favorable outcomes by the total number of possible outcomes. Thus, the probability of rolling a number greater than 2 on a six-sided die is 4/6 or reducing to its simplest form becomes 2/3.

Answer:

The answer is A.

Step-by-step explanation:

The distance between -15 and 20 on the number line is 35 units, calculated by taking the absolute difference between the two numbers.

The distance between two points on a number line can be found by taking the absolute difference between those points. To find the distance between -15 and 20, you subtract the smaller number from the larger one and take the absolute value:

|20 - (-15)| = |20 + 15| = |35| = 35

Therefore, the distance between -15 and 20 is 35 units.

Answer: Number of children is 5268

Step-by-step explanation:

Since we have given that

The ratio of men to women to children is given by

17:9:12

So,

Number of men be 17x

Number of women be 9x

Number of children 12x

According to question, we have there are 3512 more men than women ,

so,

[tex]17x-9x=3512\\\\8x=3512\\\\x=\frac{3512}{8}\\\\x=439[/tex]

So, Number of children is given by

[tex]12x=12\times 439=5268[/tex]

The number of children who attend the game are:

                   5268

The ratio of number of men to number of women to the number of children is given by:

           17:9:12

Let x be a constant such that we may define:

Number of men are: 17x

Number of women are: 9x

and the number of children are: 12x

There are 3512 more men than women.

This means that:

        17x-9x=3512

i.e.    8x=3512

i.e.  x=439

Hence, the number of children who attend the game are:

           12x=12×439

               = 5268

Answer:D

Step-by-step explanation:

You have an 8 out of 19 chance to grab a potato soup.

The probability of randomly selecting a can of potato soup from the shelf of 19 cans is 8/19. This situation involves the concept of probability in mathematics where you divide the number of favorable outcomes by the number of total outcomes.

The subject of the question is probability, which falls under the broader category of mathematics. The question is about finding the probability of selecting a can of potato soup from a shelf.

If we look at this question in terms of probability,

we first identify the total number of outcomes, which refers to the total number of cans on the shelf. There are 2 cans of tomato soup, 8 cans of vegetable soup, 1 can of chicken noodle soup, and 8 cans of potato soup, giving us a total of 19 cans.

The desirable outcomes are the number of cans of potato soup, which is 8.

The probability of an event is given by the ratio of the number of favorable outcomes to the number of total outcomes. In this instance, the probability of pulling out a can of potato soup is therefore 8/19.

To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction. To do these conversions, one needs to perform a few calculations. One also has to understand the definitions of "mixed number," "improper fraction" and "proper fraction."

A proper fraction is a fraction that has a lower number in the numerator and a higher number in denominator, such as the fraction three-fourths. An improper fraction is the inverse of this, which entails the higher number in numerator and lower number in the denominator, like 5/3. A mixed number is a whole number with a fraction, such as 1 3/4.

To convert the mixed number 1 3/4, one has to multiply the denominator 4 by the whole number 1 that gives 4, add this 4 to the 3 in the numerator to get 7 and place 7 over the denominator to find the improper fraction 7/4. In this case, this is the lowest form for this mixed number. However, if the mixed number is 6 4/6, then this converts to the improper fraction 40/6. One can divide the numerator and denominator of 40/6 by 2 to find that 20/3 is the lowest form for the mixed number 6 4/6.To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction.
