If you would like to know how long will it take to drain the pool, you can calculate this using the following steps:

3 hours ... 250 gallons
x hours = ? ... 150 gallons (= 400 - 250)

3 * 150 = 250 * x
x = 3 * 150 / 250 
x = 1.8 hours

3 hours + 1.8 hours = 4.8 hours

The correct result would be B. 4.8 hours.

Ray Of Light [21]

Answer:

  • 75°

Step-by-step explanation:

<u>We know that:</u>

  • sin 30° = 1/2, therefore arcsin (1/2) = 30°
  • tan 45° = 1, therefore arctan (1) = 45°

<u>So the value of the expression is:</u>

  • arcsin (1/2) + arctan (1) = 30° + 45° = 75°
