Explanation

A funnel is a tube or pipe that is wide at the top and narrow at the bottom,

used for guiding liquid or powder into a small opening. 

Explanation

Use the formula:  

°C = (°F − 32) × 5/9

= (200 − 32) × 5/9 = 168 × 5/9 ≈ 93.3°C

Explanation

To find the average speed, use the formula:

Average Speed = Total Distance / Total Time

---

Step 1: Total Distance  

= 30 km + 30 km = 60 km

---

Step 2: Time taken in each segment

- First 30 km at 40 km/h  

  Time = Distance ÷ Speed = 30 ÷ 40 = 0.75 hours

- Next 30 km at 20 km/h  

  Time = 30 ÷ 20 = 1.5 hours

---

Step 3: Total Time  

= 0.75 + 1.5 = 2.25 hours

---

Step 4: Average Speed  

= Total Distance ÷ Total Time = 60 ÷ 2.25 = 26.67 km/h

Explanation

Unlike the others, a snake is a reptile.

The rest (Cat, Elephant, Dog) are mammals.

√48 ≈ 6.928

Explanation

(1 ÷ 5) × 100 = 20%

Explanation

Simplify: 12 × (18/9)

Step:  

18 ÷ 9 = 2  

12 × 2 = 24

Explanation

445 mm - 198 mm + 250 mm = ?

Step 1: 445 - 198 = 247 mm  

Step 2: 247 + 250 = 497 mm  

Convert to cm:  

497 mm = 49.7 cm  

Explanation

5x - [3x + (4x - 2x)]

First, simplify inside the parentheses:  

4x - 2x = 2x

Now:  

5x - [3x + 2x]  

= 5x - [5x]  

= 5x - 5x  

= 0
