Explanation

During soap making, glycerin separates by dissolving in the salty (sodium chloride) water layer.

It does not react with sodium chloride or evaporate with steam.

Explanation

Let's calculate the final selling price after two successive discounts of 10% and 5% on the marked price of Rs. 2000.

Step 1:

First discount = 10% of 2000 = 0.10 × 2000 = Rs. 200

Price after first discount = 2000 - 200 = Rs. 1800

Step 2:

Second discount = 5% of 1800 = 0.05 × 1800 = Rs. 90

Price after second discount = 1800 - 90 = Rs. 1710

Final selling price = Rs. 1710

Explanation

Shirt has the short vowel sound /ɜːr/ (as in "hurt" or "bird").

"Ball" and "Read" have long or different vowel sounds.

Explanation

Let's solve the equation step by step:

3(y - 2) + 4(y - 3) = 5y + 14 - 4(y - 8)

Expanding the equation:

3y - 6 + 4y - 12 = 5y + 14 - 4y + 32

Combine like terms:

7y - 18 = y + 46

Subtract y from both sides:

6y - 18 = 46

Add 18 to both sides:

6y = 64

Divide by 6:

y = 64 / 6

y = 32 / 3

Explanation

The even numbers from 2 to 18 are: 2, 4, 6, 8, 10, 12, 14, 16, 18.

To find the average, we'll add these numbers and divide by 9:

Sum = 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 = 90

Average = Sum / Number of terms

= 90 / 9

= 10

Explanation

To factorize the quadratic expression x² - 12x + 35, we need to find two numbers whose product is 35 and whose sum is -12.

The numbers are -7 and -5, since (-7) * (-5) = 35 and (-7) + (-5) = -12.

So, the factorization is:

x² - 12x + 35 = (x - 7)(x - 5)

Explanation

To find the area of the road, we need to find the area of the garden and subtract the area of the inner garden (without the road).

Garden area = Length * Width

= 75 cm * 82 cm

= 6150 cm²

Inner garden dimensions:

Length = 75 cm - 2 * 5 cm = 65 cm

Width = 82 cm - 2 * 5 cm = 72 cm

Inner garden area = 65 cm * 72 cm

= 4680 cm²

Road area = Garden area - Inner garden area

= 6150 cm² - 4680 cm²

= 1470 cm²

Explanation

A force is a vector quantity.

Force is requires both magnitude (strength) and direction to be fully described.

Explanation

In the double-touch method, opposite poles (north and south) of two magnets are rubbed on the material in opposite directions to magnetize it effectively.

This helps align more magnetic domains inside the material.
