I think a straight edge will be best for you to use

The only way I can envision this is put all 4 points on 1 line segment. They go in the order of ADCB. I can only draw it this one way.
Given
D is the midpoint of AC
C is the midpoint of DB
AC = 3 cm
Argument
AC = 3 cm Given
AD = DC D is the midpoint of AC
AD = 3/2 Definition of a midpoint.
DC = 3/2 Definition of a midpoint
DC = 3/2 Last statement
DC + CB = 1.5 + 1.5. C is the midpoint of BD
DB = 3 Consolidation of equals
AD + DB = AB
1.5 + 3 = 4.5 Substitution.
Answer:
Millimeters per hour.
Step-by-step explanation:
Since its a water sprinkler, you would know that it doesn't cover miles of land, nor is it a food, so it isn't grams. Meters would seem like the right answer, but if you calculate meters to millimeters, you would see that meters are not covered in seconds. So the correct answer is millimeters per hour.
Im assuming the question is asking: if she collected $22 in sales tax what was the cost of the items her store sold. you should make sure you type the question correctly otherwise it'll be hard to answer.
going with my assumption of what the question is, we want to find the total cost of all items her story sold. let that cost be c. since there is 5% sales tax on everything and we know the sales tax is worth $22,m we have:
5%(c) = 22
dividing both sides by 5% (or .05) gives:
c = $440
For this problem, I have to know the amount of distance to get to Room 117. If I do, I can give an exact answer to this problem. Through dimensional analysis, you have divide distance with speed to determine the time:
Time = Distance/Speed
Time = d/4
As long as you know the distance, when you substitute it to d in the equation, you can already answer the time.
