Would a step-up transformer or a step-down transformer be used to convert 260 volt AC current from a household input into a 13 volt AC output in a portable electric fan? Determine the ratio of the number of input wire coils to output wire coils on the transformer.​

Answers

Answer 1

Answer:

20:1

Step-by-step explanation:

It is given that,

Input voltage = 260 volt

Output voltage = 13 volt

We need to find the ratio of the number of input wire coils to output wire coils on the transformer.​

For a step-down transformer,

[tex]\dfrac{V_i}{V_o}=\dfrac{N_P}{N_S}\\\\\dfrac{N_P}{N_S}=\dfrac{260}{13}\\\\=\dfrac{20}{1}[/tex]

Hence, the required ratio is 20:1.

Unknown:

Number of eggs in the pile = ?

Solution:

To find the number of eggs in the pile, simply add the original amount of eggs to that which was added;

             Number of eggs in pile  = (62 + 6)eggs = 68 eggs

Jason solved the following equation to find the value for x.


–8.5x – 3.5x = –78


x = 6.5


Describe how Jason can check his answer.

Answers

To check his answer, he would put substitute 6.5 for every x in the equation:

-8.75(6.5) - 3.5(6.5) = -78

-56.875 - 22.75 = -78

-79.625 = -78

Because this isn’t true, his answer is wrong

Sample answer:

Substitute the value for x into the original equation. Simplify using order of operations. If the statement is true, Jason’s solution for x is correct. If the statement is false, Jason’s solution for x is incorrect.

Step-by-step explanation: (My answer)

1) Subtract 8.5 and 3.5, that equals 12.

[tex]8.5x - 3.5x = -78[/tex]

2) Multiply 78 and 12, that equals 6.5 .

[tex]\frac{12x}{12} = \frac{78}{12}[/tex]

3) Check your answer.

[tex]-8.5 (6.5) -3.5 (6.5) = -78[/tex]

Multiply 8.5 and 6.5, that equals 55.25. Next, multiply 3.5 and 6.5, that equals 22.75.Finally, you will need to subtract your answers. Subtract both 55.25 and 22.75.

Once you've done that, the answer you should get is 78.

78 is equal to 78, that is your final answer and it is correct.

8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

The slopes of parallel lines will be same.

Firstly let us find y intercept.

2=8/3(1)+b

2-8/3=b

-2/3=b

Hence, 8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.
