Explanation

Total distance:

• Length of the train: 99m
• Length of the station: 231m
• Total distance = Length of the train + Length of the station = 99m + 231m = 330m

Total time: 11 seconds

Speed:

• Speed = Distance / Time
• Speed = 330m / 11s = 30 m/s

Now, we need to convert m/s to km/h:

• 1 m/s = 3.6 km/h

So, 30 m/s = 30 * 3.6 = 108 km/h

Therefore, the speed of the train is 108 km/h.

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

by adding 3 to the previous number (9 + 3 = 12).

Therefore, the next number should be obtained by subtracting 2 from 12.

answer is 10.

Explanation

Total number of votes polled$=(1136+7636+11628)=20400$
$\therefore$  Required Percentage

$=(\frac{11628}{20400}\times 100)$%
$=57$%

OR

Total number of votes polled

= (1,136 + 7,636 + 11,628)

= 20,400

Calculate percentage

= (11,628 / 20,400×100)

= 57%

Explanation

To simplify $1.2 times 10^{48} + 1.2 times 10^{41}$ factor out the common coefficient:

$$1.2 times (10^{48} + 10^{41})$$

Since $10^{48}$ is much larger than $10^{41}$, $10^{48} + 10^{41} approx 10^{48}$

$$
Thus, the expression simplifies to:

$$1.2 times 10^{48}$$

The sum remains close to $1.2 times 10^{48}$not multiplied significantly.

Hence, the correct answer is "None."
