Answer:
8
Step-by-step explanation:
0) the basic formula is: L=v*t, where L - distance, v - speed/velocity; t - time;
1) if the person's speed in still water is 'v' and the speed of water is 5 (according to the condition), then the upstream speed is 'v-5' and the downstream speed is 'v+5';
2) according to the condition the upstream time and the downstream time are the same, it means t₁=t₂=t, where t₁=upstream time and t₂=downstream time;
3) according to the items above it is possible to make up the equation of the upstream travel: t(v-5)=3; ⇒ t=3/(v-5);
4) according to the items above it is possible to make up the equation of the downstream travel: t(v+5)=13; ⇒ t=13/(v+5);
5) if t=3/(v-5) and t=13/(v+5), then
The second dot with says x+y=360 y=8x

Answer:
4.082 radians
Step-by-step explanation:
Here we want to convert 234° into radians.
To do it, we use the fact that pi radians is equal to 180°
Then we can write two equations:
x radians = 234°
3.14 radians = 180°
Where we want to find the value of x, which is the equivalent in radians to 234°.
Now we can take the quotient of these two equations to get:
( x radians)/(3.14 radians) = (234°/180°)
Solving this for x, we get:
x radians = (234°/180°)*(3.14 radians) = 4.082 radians.
