Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind

Answer:
The value of x = 8.1 units
Step-by-step explanation:
<em>Note: I am assuming we have to determine the value of the side 'x'.</em>
Given
Angle Ф = 32°
To determine:
x = ?
Using the trigonometric ratio
tan Ф = opposite / adjacent
here
Ф = 32°
opposite to angle 32° = x
adjacent to angle 32° = 13
Therefore,
substituting adjacent = 13, Ф = 32°, opposite = x in the equation
tan Ф = opposite / adjacent


x = 8.1 units tan 32° = 0.62
Therefore, the value of x = 8.1 units

Step-by-step explanation:
<u>nine equals</u> the quotient of a number and 54
/\
9 = <u>the quotient</u> of a number and 54
/\
9 = <u>will be division of a number and 54</u>
/\
9 =
