Can someone me on these two questions

Step-by-step explanation:

Left Picture

You have two conditions here.

On the left is -6 > x.

Minus six is not part of the system.

On the right you have x≥3. The three is part of the inequality.

The answer should be -6 > x or x≥3

So the answer should be B

Right Picture

A is close, but because the endpoint is open, -5 is not part of the solution.

Don't choose A.

B has two closed ends.

-5 ≤ x ≤ 0 So this is one choice.

C

- 5 > x but - 5 is an endpoint that is not included in the inequality because the end marker is open. Don't choose C

D

The two end points are both open but it does not matter. -5 is between those two endpoints and therefore is included in the line segment. -7<x<1

So the answer is B and D

○ x < 6 OR x ≥ 3

Step-by-step explanation:

Everything to the left of negative six is less, PLUS an OPENED CIRCLE, so it is less than, NOT less than or equal to. Everything to the right of three is great, PLUS a CLOSED CIRCLE, so it is greater than or equal to, NOT greater than.

I am joyous to assist you anytime.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
