17 units
Step-by-step explanation:
Use distance formula, 
, to find the distance between (-9, 5) and (8, 5):
Let,
Plug in the values into the distance formula:
Answer:
When 2 people work together the total time equals
Total Time = Time 1 * Time 2 / (Time 1 + Time 2)
Let's solve for Time 1 (which will be Tim's time.)
7 hours = Time 1 * 9 / (Time 1 + 9)
7 * Time 1 + 63 = Time 1 * 9
63 = 2 * Time 1
Time 1 = 30.5 Hours (Tim's Time)
Double Check
Total = 30.5 * 9 / (30.5 + 9)
Total = 274.5 / 39.5
Total = 7 Hours
Again, Tim's Time is 30.5 Hours
Step-by-step explanation:
Answer:
32.5
Step-by-step explanation:
130 / 4 = 32.5
Therefore,
4's there in 130 is 32.5
Answer: A (0.34 kl)
working:
34 dekalitres = 340 litres
340 litres = 0.34 kilolitres
Therefore, 0.34 kl
(deka = 1 x 10)
(kilo = 1 x 10^3)
