8 0

Answer:

424

Step-by-step explanation:

When rounding off, values from 5 to 9 are taken as 1 while values from 0 to 4 are taken as 0 .

When you round the value up or down , you add it to the next value. Remember it’s done from right to left

So, given 423.6059,

9 is taken as 1 and added to 5 which becomes 6. 6 also becomes 1 and added 0 which which becomes 1. 1 is 0 and added to 6. Finally, 6 becomes 1 and is added to 3 making it 4 .

So we are left with 424 which is now in 3 significant figures

nataly862011 [7]

Answer:

<em>The speed of a boat in still water is 6 miles per hour. </em>

Step-by-step explanation:

t = \frac{20}{s-2}  (upstream)

t = \frac{40}{s+2}  (downstream)

\frac{20}{s-2} = \frac{40}{s+2}

40 ( s - 2 ) = 20 ( s + 2 )

40s - 80 = 20s + 40

20s = 120

s = 6 mi / h

<em>The speed of a boat in still water is 6 miles per hour.</em>
