If D is the midpoint of segment AC , C is the midpoint of segment AB , and AD = 3 cm, what is the length of segment BC ?\

6

Step-by-step explanation:

If D is the midpoint of AC, that means that AC = AD * 2 = 3 * 2 = 6. And if C is the midpoint of AB, that means BC = AC = 6.

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

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
