Answer:

The correct options are 1 and 3.

Step-by-step explanation:

Let,

p: A shape is a triangle.

q: A shape has four sides.

It is given that the shape is a rectangle. It means q is true and p is false.

1. p ∨ q is true if and only if p  is true, or q is true.

Here q is true, therefore this option is correct.

2. p ∧ q is true if and only if p is true and q is true.

Here p is false, therefore this option is incorrect.

3. p → q is true if and only if the p is false or q is true.

Here p is false and q is true, therefore this option is correct.

4. q → p is true if and only if the q is false or p is true.

Here p is false and q is true, therefore this option is incorrect.

Therefore the correct options are 1 and 3.

babunello [35]

Answer:

The movie was 1 hour and 35 minutes long. (Or 95 minutes long)

Step-by-step explanation:

Well let's see:

It will take 15 minutes from the start to reach 5:00 PM

4:45+0:15=5:00

Now it will be 1 hour and 20 minutes from 5:00 PM to reach the end time of the movie.

Adding the minutes and hours together:

1 hour + 20 minutes + 15 minutes = 1 hour and 35 minutes

Two old RSM students were standing ten feet apart when they ran in opposite directions with speeds of 180 feet per minute and 16
inessss [21]

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

  • Since one student runs at a speed of 180 feet per minutes, in time t minutes, he moves a distance of d = 180t.
  • Also, the second student runs at a speed of 160 feet per minute, in time t minutes, he moves a distance of d' = 160t.

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

<h3>Number of minutes before they are 1870 feet</h3>

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes
