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.

Answer:

its c. all credits go to the girl/boy up there.

Step-by-step explanation:

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

Hence the option (c) is correct.

Step-by-step explanation:

The shaded area is the area GREATER than ('>') the graph (it is ABOVE the graph)

the two zeroes (where it crosses the x -axis) of the graph are - 6 and 18

so the parabola   is  y = (x+6)(x-18)

  but we want the shaded region so it becomes   y> (x+6)(x-18)

      It is '>' because the shaded area DOES NOT INCLUDE the graph line (that is why it is a dashed line)

The first term and the last term in the arithmetic progression are -2.5 and 22.5 respectively.

In Mathematics, the sum of a geometric sequence is given by this mathematical expression:

[tex]S=\frac{a_1(1-r^n)}{1-r}[/tex]

Where:

Mathematically, the sum of an arithmetic sequence is calculated by using this expression:

Sn = n/2(2a₁ + (n - 1)d)

Where:

Since the sum of all the terms in the geometric progression is equal to the sum of all the terms in the arithmetic progression, we have:

256(1 - 0.5^8)/(1 - 0.5) = 51/2(2a₁ + (51 - 1)0.5)

256(1 - 0.00390625)/(0.5) = 25.5(2a₁ + 25)

255/0.5 = 51a₁ + 637.5

510 = 51a₁ + 637.5

51a₁ = -127.5

a₁ = -2.5

For the last term, we would use the following formula:

aₙ =  a₁ + (n - 1)d

a₅₁ =  -2.5 + (51 - 1)4

a₅₁ =  -2.5 + (50)0.5

a₅₁ = 22.5.

The probability that Ben will find two worthless $10 bills in his wallet is practically impossible.

Probability is a branch of mathematics that deals with the likelihood of an event occurring. It is the measure of the likelihood of an event occurring divided by the number of possible outcomes. Probability is used to determine the chances of a particular outcome occurring and can range from 0 to 1.

The probability that each bill will be a worthless $10 bill is very low. This is because the US Federal Reserve has discontinued the production of $10 bills in 2006, so the likelihood of finding two of them in circulation is highly unlikely. Additionally, bills are often replaced after a certain amount of time due to wear and tear, so the probability of finding two bills in circulation that are both from the discontinued series is even lower.

The chances of finding two $10 bills from the discontinued series in circulation is so extremely rare that it has been estimated to be one in ten million. Even though it is possible to find two bills from the discontinued series, it is extremely unlikely that one would carry two of them in their wallet.

Answer:5:1

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.

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:
