Speed = Distance ÷ time 

Speed upstream = 84 ÷ 7 = 12 km/h

Speed downstream = 84 ÷ 3 = 28 km/h

Speed in still water = 1/2(28 + 12) = 20 km/h

Answer: 20 km/h

Which number is in the 3rd position after ordering in<br> descending order. V220,-10, V100, 11.5
Alenkinab [10]

Answer:

√100

Step-by-step explanation:

Given the following numbers: √220, -10, √100, 11.5,

Let's arrange the numbers from the largest to the smallest (in descending order).

Note: √220 ≈ 14.8

√100 = 10

From the largest to the smallest number, we have: √220, 11.5, √100, -10

Therefore, the number in the third position is √100

In order to complete the service line information on claims when units of measure are involved insurance math is required. For e
tigry1 [53]

Answer:

The service line is J9263 x 300 to report a unit of 150(300x 0.5 mg = 150).                    

Step-by-step explanation:

The drug J9263 Eloxatin contains 0.5 mg oxaliplatain.

<u>For a infusion of 50 mg the unit reported for service line information is</u>:

- <em>Service line:</em> J9263 x 100

- <em>Unit reported for service line information:</em> 50 = 100 x 0.5 mg

Hence, for a infusion of 150 mg, the unit reported for service line information is:

- <em>Unit reported: </em> 150(300 x 0.5 mg = 150)

- <em>Service line information:</em> J9263 x 300

Therefore, if the physician provided 150 mg infusion of the drug instead of an injection the service line is J9263 x 300 to report a unit of 150(300x 0.5 mg = 150).

I hope it helps you!
