What is the reading in kwh of the electric meter shown in the exam figure below?
Answers
Answer:
(C)=0631
Step-by-step explanation:
Kwh is the unit of measurement which is equal to the amount of the energy being used or the amount of energy you are using.
In order to get the readings of kwh of the electric meter, take the smallest reading when there are numbers from 0 to 9 and zero is always taken if the meter points between the number 9 and 0.
Hence, from the given meter, the first meter points between 0 and 1, thus reading will be 0 as 0 is the smallest of the two. Next, the reading is between 6 and 7, therefore the reading will be 6. similarly, the rest readings will be 3 and 1. Therefore, the correct reading will be: 0631
The answer is letter C. 0631. Always read the dial from left to right. If the dial is in between the numbers, choose the smaller number. If it is between 9 and 0, choose 9.

Answer:
Multiply 2x + 3y = −1 by 5. Multiply 3x − 5y = 10 by 3. Add the resulting equations together.
Step-by-step explanation:
To eliminate the y-term. we must multiply both equations by values that make the coefficients of y opposite in sign.
2x + 3y = -1 (1)
3x - 5y = 10 (2)
The easiest way to do this is to multiply Equation (1) by 5
and Equation (2) by 3.
5 × [2x + 3y = -1]
3 × [3x - 5y = 10]
Then, add the two equations.
10x + 15y = -5
9x - 15y = 30
19x = 25
Conclusion: Multiply 2x + 3y = −1 by 5. Multiply 3x − 5y = 10 by 3. Add the resulting equations together.

√ ( - 28 )
We know that √ (-1 ) = i ( the imaginary unit )
√ ( - 28 ) = √ 28 * ( - 1 ) = i √ ( 28 ) = i √ ( 4 * 7 ) = 2 i √( 7 )
But there is not such solution among the options.
Only correct answer ( using the imaginary unit ) is:
C. i (square root) 28
The simplified form is 2√7i.
Hence none of the provide option correct.
To simplify the square root of -28 using the imaginary unit i, we can first express -28 as a product of a positive number and -1:
The square root of -28 is equal to the square root of 28 times the square root of -1, which simplifies to 2 times the square root of 7 times i So, the simplified expression is:
2√7i.
The correct answer is not among the options provided.
The simplified form is 2√7i.
