4.4 hours

or

4 hours 24 minutes

Step-by-step explanation:

Remember that

1 hour=60 minutes

step 1

Convert the amount of time each week for a month in minutes

so

a) 1 hour 3 minutes

b) 1 hour 18 minutes

c) 55 minutes

d) 68 minutes

step 2

Adds the minutes

step 3

Convert to hours

Divide by 60

step 4

Convert to hours and minutes

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
