It would be helpful if you draw a figure of the problem statement so that you would understand it clearly. You would see that a right triangle would be formed where the base is equal to the horizontal distance from the airplane to the atoll which is 5172 and the angle from the ground to the atoll would be equal to the angle of depression. We calculate as follows:
tan (theta) = opposite/ adjacent
tan (10) = height / 5172
height = 911.96 units of length
The x intercept is the value of x when y=0
the y intercept is the value of y when x=0
when y=0: 4x-0=24 => x=4
when x=0: 0-8y=24 => y=-3
so the x intercept is 4, and the y intercept is -3
Step-by-step explanation:
Since X : Y = 1 : 2, X = 0.5Y.
Since Y : Z = 2 : 5, Z = 2.5Y.
We have X + Y + Z = 4Y = 40. Hence Y = 10.
If he can swim 10 laps in 23 mins so how long he can swim the 15 laps?
you can say:
10/23 = 15/?
so ? is the answer:
15*23/10 = 34.5 mins :)))
i hope this is helpful
have a nice day
