Hello,
The two lights flash at the same time every 18 min
at 8:00 h=480 min =480+0*36
at 8:36 h=516 min =480+1*36
...
54 is not divisible by 36
60+12=72 = 2*36 yes
60+24=84 not
120+24=4*36 yes
180+18=198 not
So 2 times are correct 9:12 and 10:24
Answer G
Answer:
(-10, 10) and (0,10).
Step-by-step explanation:
For a point to be a solution to the system of inequalities, you will need to see which of the points falls into the shaded area.
When we test out each of the points, we can see that only:
(-10, 10) and (0,10) fall into the blue-shaded area.
Answer:
The common ratio of the geometric sequence is:

Step-by-step explanation:
A geometric sequence has a constant ratio 'r' and is defined by

where
Given the sequence

Compute the ratios of all the adjacent terms: 

The ratio of all the adjacent terms is the same and equal to

Therefore, the common ratio of the geometric sequence is:
3.8 or 8.3 I believe it’s 3.8 though, sorry, I’m not that smart.
