Explanation

Given cosx(tan x + cot x):

Step 1: Express tan x and cot x in terms of sin x and cos x

tan x = sin x / cos x

cot x = cos x / sin x

Step 2: Substitute and simplify

cosx(tan x + cot x) = cosx(sin x / cos x + cos x / sin x)

= sin x + cos² x / sin x

= (sin² x + cos² x) / sin x

= 1 / sin x (since sin² x + cos² x = 1)

Step 3: Identify the result

1 / sin x = cosec x

Explanation

To express 27 minutes 30 seconds and 1 hour in ratio:

Step 1: Convert both times to seconds

27 minutes 30 seconds = (27 * 60) + 30

= 1620 + 30

= 1650 seconds

1 hour = 60 minutes = 60 * 60

= 3600 seconds

Step 2: Calculate the ratio

Ratio = 1650 : 3600

To simplify, divide both parts by their greatest common divisor, which is 150:

= (1650 / 150) : (3600 / 150)

= 11 : 24

Explanation

Given the area of the square is 16 cm²:

Step 1: Find the side length

Area = side²

16 = side²

side = √16

side = 4 cm

Step 2: Calculate the diagonal

The diagonal of a square can be found using the formula d = side√2.

d = 4√2

Explanation

Balancing the equation requires equal atoms of each element on both sides.

Here, 2 molecules of KNO₃ decompose into 2 molecules of KNO₂ and 1 molecule of O₂ gas.
