We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour

ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph

GO.o has 3 orange picks for every 2 green. If there are 25 picks in all, how many picks are orange?
Reika [66]

Given

GO.o has  3 orange picks for every 2 green

there are 25 picks in all

Find out how many picks are orange.

To proof

As given in question

GO.o has  3 orange picks for every 2 green

i.e the ratio of orange to every green becomes

\frac{Orange}{Green}:\frac{3}{2}

total number of picks = 25

let the GO.o pick of  3 orange picks for every 2 green =x

than the equation becomes

3x + 2x = 25

5x = 25

x = 5

Than

the number of oranges = 3x

putting the value  of x

                                     = 15

the number of green = 2x

                                  =  10

thus the 15 picks are orange.

Hence proved

What is the measure of x?<br> A.36<br> B.72<br> C.144<br> D.360
Helga [31]
We know that the interior angles of a trapezoid add up to 360 degrees. 

Write out an equation to represent this situation; 

108+108+2x+2x=360 
216+4x=360
4x=360-216 
4x=144 
x=144/4 
x=36 

Therefore, the measure of x is 36 degrees. 

Hope I helped :)
