I'd suggest you write "6 2/5," not "6 and 2/5."

6 2/5 rotations
-------------------- = 
2 2/3 seconds

32
---
 5            32       3
------- = ------ * -----
 8              5       8                 Reduce that 32/8:  obtain 4.
---
 3

Then we have

4(3)/5, or 12/5 rotations per sec.

In calm water, the motorboat of Jana is moving at the speed of 16.5km/h. On a river, because of the current, the boat moves fast
ki77a [65]

Answer: 707 km/h

Step-by-step explanation:

let c = speed of current

16.5 + c = speed of sailboat downstream

16.5 - c = speed of sailboat upstream

distance = travel time * speed

﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋

2(16.5 + c) = 5(16.5 - c)

33 + 2c = 82.5 - 5c

7c = 49.5

c = 7.07 km/h

x^2-4x+x-4=0

x(x-4)+1(x-4)=0

(x+1)(x-4)=0

x=-1,4

x- intercepts in the point (-1,0) and (4,0)
