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.

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.

Answer:

(1, 3), (0, 6) and (-2, 5)

Step-by-step explanation:

First we will translate the image 2 left and 2 down to account for moving the center of dilation (2, 2) away from the origin:

(0, 4)→(-2, 2)

(-2, 10)→(-4, 8)

(-6, 8)→(-8, 6)

Next we apply the scale factor of 1/2:

(-2, 2)→(-1, 1)

(-4, 8)→(-2, 4)

(-8, 6)→(-4, 3)

Lastly we translate the figure back 2 right and 2 up:

Remark

It is not a straight line distance from the park to the mall. None of the answers give you that result. And if you know what displacement is, none of the answers are really displacement either. The distance is sort of a "as the crow flies." distance. There's a stop off in the middle of town.

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

Answer

Total distance = 5 + 2.8 = 7.8

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]

Multiply by 25 on both sides

300 = 10k (divide by 10)

So k = 30

Lets find y when x is 6 and t = 3. we got k = 30

[tex]6 = \frac{30*3}{y}[/tex] (cross multiply)

6y = 90 (divide by 6 )

[tex]y = \frac{90}{6} =15[/tex]

The value of y = 15

Answer:

15

Step-by-step explanation:

If x varies inversely as y and directly as t, and x = 12 when t = 10 and y = 25, find y when x is 6 and t = 3.

There's the expression

The slope of a line passing through two points is found by taking the change in y-coordinates divided by the change in x-coordinates. For the given points (1, 0.1) and (7, 26.8), the slope is approximately 4.45.

The slope of a line passing through two points can be found using the formula:

slope = (change in y-coordinates)/(change in x-coordinates)

Given the points (1, 0.1) and (7, 26.8), the change in y-coordinates is 26.8 - 0.1 = 26.7 and the change in x-coordinates is 7 - 1 = 6. Substituting these values into the formula, we get:

slope = 26.7/6

slope ≈ 4.45

Answer:

Fractional part of the mixed number is [tex]\frac{23}{45}[/tex].

Step-by-step explanation:

First we have to simplify the given expression,

[tex]\frac{8668}{25} +\frac{4141}{9} -\frac{5533}{25}[/tex]

=[tex]\frac{(8668*9)+(4141*25)-(5533*9)}{25*9}[/tex]

=[tex]\frac{(8668-5533)*9+(4141*25)}{25*9}[/tex]

=[tex]\frac{(3135*9)+(4141*25)}{25*9}[/tex]

=[tex]\frac{28,215+103,525}{225}[/tex]

=[tex]\frac{131,740}{225}[/tex]

=[tex]\frac{26,348}{45}[/tex]

=[tex]585.51111[/tex]

Now we have to take the whole number that we get by dividing numerator by denominator,

It is 585

Now we have to find the remainder after taking the numerator,

[tex]26,348-(585*45)=23[/tex]

Now we represent the whole number and the fraction of remainder together as a mixed number.

[tex]585\frac{23}{45}[/tex]

Therefore, fractional part of the mixed number is [tex]\frac{23}{45}[/tex].

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.

Two different facts using the original fact of 147 multiplied by 16 to reach the product of 2352 are 73.5 multiplied by 32 and 147 multiplied by 16.

To find two different multiplication facts that have a product of 2352, using the fact that 147 multiplied by 16 equals 2352, we can manipulate the factors in various ways. One way is to halve one of the factors and double the other. If we take half of 147, we get 73.5, and doubling 16 gives us 32. Therefore, 73.5 multiplied by 32 is one multiplication fact that equals 2352. Another way is to multiply both factors by the same number. If we multiply both 147 and 16 by 1, technically we get a different multiplication expression with the same product. This means 147 multiplied by 16 is still valid since we have applied the identity operation (multiplying by 1).

In summary, two different facts using the original fact of 147 multiplied by 16 to reach the product of 2352 are 73.5 multiplied by 32 and 147 multiplied by 16.
