Explanation

Every constant term in an expression has degree 0 because it has no variable part.

The degree refers to the highest power of the variable in the term; constants have no variable, so the degree is zero.

Explanation

23 × 2 = 46

46 + 3 = 49

49 - 1 = 48

Explanation

Find LCM of 20, 30, and 40:

Prime factors:

20 = 2² × 5

30 = 2 × 3 × 5

40 = 2³ × 5

LCM = 2³ × 3 × 5 = 120 minutes

120 minutes = 2 hours, so if they ring together at 9:00 am, they will ring together again at 11:00 am.

Explanation

A seven-digit number starts from 1,000,000 and goes up to 9,999,999.

1000000 is the smallest possible number with exactly seven digits.

Explanation

The Least Common Multiple (LCM) of 3 and 4 is 12, the smallest number divisible by both.

Multiples of 3: 3, 6, 9, 12...

Multiples of 4: 4, 8, 12...

Explanation

We are given the equation:

w = (2/3)t + 6

and asked to find w when t = 12.

Step-by-step:

w = (2/3 × 12) + 6

w = 8 + 6

w = 14

Explanation

The type of partial fractions you get depends on how the denominator factors (e.g., linear or quadratic factors).

The numerator is adjusted based on the denominator’s factors, but the process primarily depends on the denominator.

Explanation

The logarithm of any number to itself as base is 1.

This is because log(a)/a = 1, where 'a' is any number.

Explanation

4+4-4x4/4=?

=4+4-4x1

=4+4-4

=4+0

=4

Explanation

First-year get 10% 100000/100*10 = 10000

100000-10000 =90000

2nd Year get 10% 90000/100*10 = 9000

9000-90000 = 81000
