1 answer:
Answer:
$46.746
Step-by-step explanation:
Allen is buying a video that originally cost = $ 49
Discount coupon = 10%
Sales tax= 6%
Hence, the price of video after discount coupon and sales tax= $ 49 ××
Hence, the price of video after discount coupon and sales tax= $ 49 ××
Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06
price of video after discount coupon and sales tax= $46.746
Hence, the correct answer is $46.746

Answer:
The horizontal distance from the plane to the person on the runway is 20408.16 ft.
Step-by-step explanation:
Consider the figure below,
Where AB represent altitude of the plane is 4000 ft above the ground , C represents the runner. The angle of elevation from the runway to the plane is 11.1°
BC is the horizontal distance from the plane to the person on the runway.
We have to find distance BC,
Using trigonometric ratio,
Here, ,Perpendicular AB = 4000
Solving for BC, we get,
(approx)
(approx)
Thus, the horizontal distance from the plane to the person on the runway is 20408.16 ft
