Georgia participated in a sleep study in which scientists found that she fell into REM sleep exactly every 45 minutes while she was asleep. If Georgia was asleep for 6One-half hours (390 minutes), how many periods of REM sleep did she have?

8 period

Step-by-step explanation:

Divide 390 with 45.

You can see that 390 is 6 hours 30 minutes

While 6 hours is 8 × 45 minutes

Because 30 minutes is less than 45 minutes,

Thus she slept for 8 periods of REM.

I hope this helps you :)

8 period

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
