Option C is the correct answer, as it states that the difference between 3 1 4 and 1 2 3 is 1 7 12The question is asking if Emily has 123 more cups of flour than sugar.

To check if this is true, we can subtract the amount of sugar from the amount of flour, and see if the difference is equal to 123.

Emily uses 1 2 3 cups of sugar and 3 1 4 cups of flour.

Therefore, the difference between the amount of flour and the amount of sugar is:

3 1 4 − 1 2 3 = 12/4 + 3/4 - 3/12 = 9/12 + 9/12 - 1/12 = 17/12

The difference between the amount of flour and the amount of sugar is 17/12, not 123. Therefore, we cannot agree with Emily's statement that she has 123 more cups of flour than sugar.

Option C is the correct answer, as it states that the difference between 3 1 4 and 1 2 3 is 1 7 12, which is the same as our calculation above. Options A and B are incorrect because they give incorrect values for the difference. Option D is incorrect because it gives the sum of the two quantities, not the difference.

Any number that can be expressed as a ratio of two integers is called a rational number.

Any number that can be expressed as a ratio of two integers is called a rational number. The word "rational" comes from the word "ratio", which means a comparison of two quantities. In other words, a rational number is a number that can be written in the form p/q, where p and q are integers and q is not equal to 0. For example, 2/3, -5/7, and 1 are all rational numbers, while pi (π) and √2 are not rational because they cannot be expressed as a ratio of two integers.

Rational numbers can be positive, negative, or zero. They can also be expressed in different forms, such as mixed numbers or decimals. However, it is important to note that not all decimals are rational. A decimal is rational if and only if it either terminates or repeats indefinitely. For example, 0.25, 0.5, and 0.333... are all rational decimals, while 0.7 and 0.1234567891011121314... are not rational.

It takes approximately 35.35 seconds to fill the glass 50%. Rounded to two decimal places, the answer is 35.35 seconds.

The volume of the cylindrical glass can be calculated as:

V = πr²h

where r is the radius (half of the diameter), h is the height, and π is the mathematical constant π (approximately 3.14).

Since the diameter is 3 inches, the radius is 1.5 inches. The height is 10 inches. Therefore, the volume of the glass is:

V = π(1.5)²(10) ≈ 70.69 cubic inches

To fill the glass 50%, we need half of the volume:

V/2 ≈ 35.35 cubic inches

The faucet dispenses water at a rate of 1 cubic inch per second, so the time it takes to fill the glass 50% is:

t = (V/2) / (1 cubic inch per second) ≈ 35.35 seconds

Therefore, it takes approximately 35.35 seconds to fill the glass 50%. Rounded to two decimal places, the answer is 35.35 seconds.

Answer:

the next fraction in the sequence is 5/7.

Step-by-step explanation:

If int j = 3, then the value of J++ is 3.

The post-increment operator ++ increments the value of the variable by 1, but returns the original value of the variable. So when j++ is executed, j is incremented to 4, but the expression evaluates to the original value of j, which is 3.

To see the effect of the increment operator, you could print the value of j before and after the j++ operation:

int j = 3;

System.out.println(j);  // output: 3

j++;

System.out.println(j);  // output: 4

Note - that the pre-increment operator, ++j, would increment the value of j and return the new value, so ++j would evaluate to 4.

j++ is a shorthand notation in many programming languages, including Java and C++, which increments the value of the variable j by 1.

The perimeter of the room is approximately 49.272 feet.If the area of a rectangular room is 150 square feet, and one side of the room is 11 feet, we can find the length of the other side by dividing the area by the length of the known side:

Length × Width = Area

Width = Area ÷ Length

Width = 150 ÷ 11

Width ≈ 13.636 feet

Now that we know the length and width of the room, we can calculate the perimeter by adding up the length of all four sides:

Perimeter = 2 × Length + 2 × Width

Perimeter = 2 × 11 + 2 × 13.636

Perimeter ≈ 49.272 feet

The given system of equations, option C. The system has a nontrivial solution.

When given a system of three equations with three unknowns, it is possible to determine if the system has a nontrivial solution by using row operations and Gaussian elimination. Nontrivial solutions are solutions that are not all 0.

In the given system of equations, the left-hand side of each equation consists of 3 variables, 4x₁-6x₂+13x₃, 4x₁-10x₂-x₃, and 8x₁+4x₂+14x₃. By performing row operations on the equations, the augmented matrix can be reduced to the form of the identity matrix.

The first row operation performed is to subtract the first row from the second row, resulting in

=> 4x₁-10x₂-x₃ = -2x₁-2x₂+13x₃.

The second row operation is to subtract twice the first row from the third row, resulting in

=> 8x₁+4x₂+14x₃ = 0.

The third row operation is to divide the second row by -2, resulting in

=> 4x₁-10x₂-x₃ = x₁+x₂-13x₃.

This reduced form of the augmented matrix can then be rearranged to the form of the identity matrix, indicating that the system of equations has a nontrivial solution.

Therefore, the answer to the question is that the system has a nontrivial solution

Answer: $5938.92

Step-by-step explanation:

GST = original price * 10% = $5999 * 0.1 = $599.90

The total GST inclusive price would be the sum of the original price and the GST, which is:

GST inclusive price = original price + GST = $5999 + $599.90 = $6598.90

Sale price = (GST inclusive price + GST) * (1 - 10%) = ($6598.90 + $599.90) * 0.9 = $6598.80 * 0.9 = $5938.92

Therefore, the correct sale price should have been $5938.92, and the car yard should have paid the 10% GST on each sale, as advertised.

Uncontrollable factors can have an effect on the result of a scenario or experiment. Here are a few strategies for dealing with such factors:

Recognize the variables, Reduce the impact, Randomization, Statistical analysis, Concentrate on what you can control.

Recognize the variables: The first stage is to identify the uncontrollable elements and acknowledge their possible effect on the result. This allows you to plan for unexpected events and alter your expectations accordingly.

Reduce the impact: Even if you can't control the circumstances, you can reduce their influence by taking particular activities. For example, if weather conditions may have an impact on the result of an outdoor event, you may want to arrange it during a more favourable time of year.

Randomization: When dealing with uncontrolled elements in a scientific experiment, randomization can assist in evenly distributing the impact of these factors among multiple groups.

Statistical analysis: In data analysis, statistical analysis can help to account for the impact of uncontrollable factors. Statistical models can provide more accurate estimates of the influence of a given variable by controlling for other variables and accounting for the variability produced by uncontrolled factors.

Concentrate on what you can control: In many circumstances, it is more productive to focus on what you can control than than fretting about what you can't. You may be able to mitigate the effects of uncontrollable elements to some extent by recognising and maximising the controllable factors.

Answer: Roughly 104.94 (because we need to use pi, and pi must round because it never ends). I really hope this helps!

Step-by-step explanation:

First, we know that to solve a circle's area, we do a(Area)=pi times radius squared. So, if the diameter of the circle is 14, then the radius is 7 (half of the diameter). That becomes pi (roughly 3.14) times 7 squared, which gives ur roughly 153.94 (because pi is never ending, so we have to round.)

If we know that the circle's area is about 153/94, and we know that the triangle's height is 7(because from the center point to the top point on the triangle, if exactly half of the full circle (diameter/2=radius, and radius is 7). Then, we would do 14 times 7(height times length) and that gives us 98, and divide by 2 which gives us 49.

Subtracting 49 from the circle's area (153.94) gives us an answer of roughly 104.94.
