Explanation

Multiplying 0.04 × 0.0162 × 0.001 gives 0.000000648.

Explanation

The sum of all odd numbers between 1 and 100 is 50^2=2500

The sum of all even numbers between 2 and 100 is 50^2+50=2550

The total of 1 to 100 natural numbers is 2500+2550

5050

The average of the first 100 numbers is 5050 / 100 = 50.50

Explanation

(0.7) ^? + 3 = (0.49 x 0.343/0.2401)^4

(0.7)^? + 3 = (0.7)^4

On comparing the exponents both sides, we get

? + 3 = 4

∴ ? = 4 - 3 = 1

Explanation

Zakat is typically 2.5% of the total wealth.

To find the total amount, divide the Zakat paid by 0.025 (8500 ÷ 0.025 = 340,000).

Explanation

To find the answer, divide 4.036 by 0.04:

4.036 ÷ 0.04 = 100.9

Explanation

In this scenario, we can use the tangent function, which is the ratio of the opposite side (height of the tower, h) to the adjacent side (the horizontal distance, 70m):

Explanation

To find how many shirts the washerman can iron in one hour (60 minutes), we can use the given rate:

• The washerman irons 4 shirts in 12 minutes.

Now, let's find how many sets of 12 minutes are there in 60 minutes:

60​/12=5

Since he can iron 4 shirts in 12 minutes, in 60 minutes he can iron:

4×5=20 shirts

Explanation

To solve this, we can start by expressing the given ratio m:n = 3:2 in terms of a variable, let's say x. So, m = 3x and n = 2x.

Now, let's substitute these expressions into the given ratio (4m+5n):(4m-5n):

(4(3x) + 5(2x)) : (4(3x) - 5(2x))

Expanding and simplifying, we get:

(12x + 10x) : (12x - 10x)

22x : 2x

Now, we can divide both terms by 2x to get: 11 : 1
