Answer:
1100 and 130 (km/h)
Step-by-step explanation:
1. if the velocity of the wind is 'w' and the velocity of the plane in still air is 'p', then
2. it is possible to make up two equations:
the fly against the wind: (p-w)*8=7760;
the fly with the wind: (p+w)*3=3690.
3. if to solve the system made up, then:

4. the required rate of the plane in still air is p=1100 km/h; the rate of the wind is w=130 km/h.

Answer:
x = 6√2
Step-by-step explanation:
The side ratios in an isosceles right triangle are ...
1 : 1 : √2
These will be the same as ...
x : x : 12
so, ...
x = 12/√2
x = 6√2
The order would be 2.05, 2.58, 2.8
1 yard is 3 feet.
18/3 = 6
Therefore, the actual ratio is 6 yards to 5 yards. Getting rid of like terms, we find that the simplest form ratio is 6:5
Answer is D.
Bring over x to replace 3 in 14/3 and bring the 3 over the x in x/y.
