Calculate the 25% of 6 hours 20 minutes​

6 hours and 20 mintues = 380 mintues

25% of 380 = 95 mintues = 1 hour and 35 mintues

Step-by-step explanation:

The answer is 95 minutes.

Step-by-step explanation:

1. Convert 6 hours to minutes which would lead to 360 minutes.

2. 360 minutes + 20 minutes = 380 minutes.

3. Now find 25% of 380 minutes.

How I found 25%.

1. 50% of 380 = 190.

2. 50% of 190 = 95.

Now since the half of our base half is 95 then 2 halfes are 2 25% but we need 1 only so we can conclude that, 25% of 380 minutes is 95.

Hope this helped :).

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
