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.

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.

Final answer:

To solve for 12 involving fractions or decimals, divide 0.40 into both sides of the equation and multiply both sides by 12.

Explanation:

Here are several equations that involve fractions or decimals and equal 12:

1. 12 = 12 (This is a simple example with no fractions or decimals, but it satisfies the condition of equaling 12.)

2. 11.5 + 0.5 = 12 (This uses two decimals to reach 12.)

3. 12/1 = 12 (This uses a fraction, specifically 12 divided by 1, which equals 12.)

4. 6 2/3 = 12 (This uses a mixed number, which combines an integer and a fraction, to equal 12.)

5. 12 x 1/1 = 12 (This shows how multiplying 12 by 1 (written as a fraction) still results in 12.)

These are just a few examples, and there are countless other equations you can create that involve fractions, decimals, or both and still equal 12.

an example that opposes or contradicts an idea or theory.

Final answer:

A counterexample is an example that disproves a statement or argument by showing that the conclusion can be false even when the premises are true. This concept is widely used in philosophy to test and refine arguments and definitions.

Explanation:

A counterexample is a specific case or example that refutes a general assertion or proposition. In philosophical reasoning and critical thinking, counterexamples hold particular significance as they can demonstrate the invalidity of an argument. The argument may have premises that are all true, but the conclusion drawn from these premises is shown to be false through the counterexample. Philosophers often use this method to refine definitions, understand the essence of concepts, and advance epistemological theories about knowledge and justification. Furthermore, it is a useful practice to generate counterexamples in order to test the validity of our own beliefs and arguments.

To identify counterexamples, one must consider a statement or argument and then conceive of a scenario where despite the premises being true, the conclusion does not follow. This act of finding counterexamples is critical for ensuring the soundness of deductive reasoning and often leads to the revision or abandonment of flawed concepts or arguments.

800-50=750 so 750+50=800 the dryer maybe go be 750

When a washer and a dryer cost $800 combined. The washer costs $50 less than the dryer the cost of the dryer is $425.

Let's assume the cost of the dryer is "D" dollars.

According to the given information, the washer costs $50 less than the dryer, so the cost of the washer would be "D - $50" dollars.

Now, we know that the combined cost of the washer and dryer is $800, so we can set up an equation:

Cost of washer + Cost of dryer = $800

(D - $50) + D = $800

Now, let's solve for the cost of the dryer (D):

2D - $50 = $800

Add $50 to both sides:

2D = $850

Now, divide by 2 to solve for D:

D = $850 / 2

D = $425

So, the cost of the dryer is $425.

x varies inversely as y and directly as t

We use formula [tex]x = \frac{kt}{y}[/tex]

x varies inversely as y so we divide by y

x varies directly as t so we multiply x

k is the constant of proportionality

Lets find out k using the given values

x = 12 when t = 10 and y = 25

[tex]x = \frac{kt}{y}[/tex]

[tex]12 = \frac{k*10}{25}[/tex]

To find the distance from Checkpoint B to the starting line, we add the distances from Checkpoint B to Checkpoint A and then double that sum.

Explanation:

To find the distance from Checkpoint B to the starting line, we need to add the distances from Checkpoint B to Checkpoint A and then double that sum. Let's calculate it step by step:

Distance from starting line to Checkpoint A: 20 yards

Distance from Checkpoint A to Checkpoint B: 12 yards

Total distance from starting line to Checkpoint B: 20 + 12 = 32 yards

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.

Method

You need to use the Pythagorean Formula twice -- once from the park to the city Center and once from the city center to the mall.

Distance from the Park to the city center.

a = 3   [distance east]

b = 4  [distance south]

c = ??

c^2 = 3^2 + 4^2        Take the square root of both sides.

c = sqrt(3^2 + 4^2)

c = sqrt(9 + 16)          Add

c = sqrt(25)

c = 5

So the distance from the park to the city center is 5 miles

Distance from City center to the mall

a = 2 miles [distance east]

b = 2 miles [distance north]

c = ??

c^2 = a^2 + b^2   Substitute

c^2 = 2^2 + 2^2   Expand this.

c^2 = 4 + 4

c^2 = 8             Take the square root of both sides.

sqrt(c^2) = sqrt(8)

c = sqrt(8)          This is the result

c = 2.8
