The amount of water flowing into a tank doubles every minute. The tank if full in an hour. When is the tank half full.

1 answer:

7 0

Given that the water in the tank doubles every minute, it implies that when the tank was full, it was half full just one minute prior. If it reaches fullness after 60 minutes, it was indeed double what it was a minute earlier. Hence, the opposite of doubling is halving. A minute before the tank filled completely, it was at half capacity. Therefore, it confirms that it was half full after 59 minutes.

babunello [11817]

Question:

Let p: x = 4 Let q: y = −2 Which represents "If x = 4, then y = −2”? p ∨ q p ∧ q p → q p ↔ q

Answer:

The correct option is c: p → q

Explanation:

Option a: p ∨ q

p ∨ q indicates that either p is true, or q is true, or both hold true.

Therefore, Option a is not the right answer.

Option b: p ∧ q

p ∧ q signifies that both p and q are true.

Thus, Option b is not the correct choice.

Option c: p → q

p → q means if p is indeed true, then q must also be true.

So, Option c is the right choice.

Option d: p ↔ q

p ↔ q implies that if p holds true, then q is true, and vice versa.

Thus, Option d is not the correct option

Therefore, p → q is the accurate option.

7040

Step-by-step explanation:

C= 2000

B = 20/100 x 2000 = 400 + 2000 = 2400

A= 10/100 x 2400 = 240+2400= 2640

2000 + 2400 + 2640 = 7040
