2/4 of an hour is how many minutes

Answer: 30 minutes

Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.

Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.

Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>

We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.

Therefore, 2/4 of an hour is 30 minutes.

Answer:

  5 hours

Step-by-step explanation:

A quick way to look at this is to compare the difference in hourly charge to the difference in 0-hour charge.

The first day, the charge is $3 more than $12 per hour.

The second day, the charge is $12 less than $15 per hour.

The difference in 0-hour charges is 3 -(-12) = 15. The difference in per-hour charges is 15 -12 = 3. The ratio of these is ...

  $15/($3/h) = 5 h

The charges are the same after 5 hours.

__

If you write equations for the charges, they will look like ...

  y1 = 15 + 12(x -1)

  y2 = 3 + 15(x -1)

Equating these charges, we have ...

  15 +12(x -1) = 3 + 15(x -1)

  12x +3 = 15x -12 . . . . . . . . eliminate parentheses

  15 = 3x . . . . . . . . . . add 12-12x

  x = 15/3 = 5 . . . . . . divide by 3

You might notice that the math here is very similar to that described in words, above.

The charges are the same after 5 hours.

What is the value of the discriminant?<br> 2K2 = 10k - 2
Phoenix [80]

Answer:

84

Step-by-step explanation:

Given a quadratic equation in standard form, ax² + bx + c = 0 : a ≠ 0

Then the discriminant is Δ = b² - 4ac

2k² = 10k - 2 ( subtract 10k - 2 from both sides )

2k² - 10k + 2 = 0 ← in standard form

with a = 2, b = - 10 and c = 2, thus

b² - 4ac = (- 10)² - (4 × 2 × 2) = 100 - 16 = 84
