Explanation

Let's calculate the values:

• (i) 0.5^2 = 0.25
• (ii) 0.5
• (iii) 0.5^3 = 0.125
• (iv) 3√(0.5) ≈ 1.26

Now, we can arrange them in ascending order (smallest to largest):

iii, i, ii, iv

Therefore, the correct answer is (B).

Explanation

The total food required for $x$ cows over 150 days is:

$$\text{Total food}=x\times 150$$

When the number of cows is reduced by 10, i.e., $x - 10$, the food lasts for 10 more days, meaning it lasts for 160 days. So, the total food required for x-10 cows over 160 days is:

$$\text{Total food}=(x-10)\times 160$$

Since the total amount of food remains constant in both cases, we can equate the two expressions for total food: x

$$x\times 150=(x-10)\times 160$$

Explanation

Sunspots are dark areas in the Sun's photosphere, which are cooler than their surroundings

The Sunspots on the Sun's Surface with a periodicity of 11 years.

Explanation

1. Let the price of an adult ticket be x
2. The price of a child ticket is x - 240
3. 18500x + 2500(x-240) = 41400000
4. 18500x + 2500x - 600000 = 41400000
5. 21000x = 42000000
6. x = 42000000 / 21000 = 2000

Explanation

Given:

$$3 (-4 times 5 - 6)$$

1. Calculate $-4 times 5$:

   $$-4\times 5=-20$$

2. Substitute and simplify inside the parentheses

   $$-20 - 6 = -26$$

3. Now multiply by 3

   $$3 times (-26) = -78$$

Explanation

Let's consider the radius is r and therefore the Area will be πr².

Now the radius is increased by 4 times than the Area would be.

π(4r)² or the area would work to 16 times (4²=16).
