An airplane travels about 1,500 Km in a straight line between Toronto and Winnipeg. However, the plane must climb to 10,000 m du
Anna007 [38]

Answer:416

Step-by-step explanation: Based on the given problem above, it requires a trigonometric solution. So here it goes:

The climb distance is:200 * Sec [ArcTan [10/200]] = 10√ 401 km

and the decent distance is:300 * Sec [ArcTan [10/300]] = 10√901 km

So add the given results above with 500 km and this will be the additional distance that plane moves through the air.

The answer would be in the unit meters.

((10√401 +10√901−500)∗1000)=416 meters

Hope this is the answer that you are looking for.

A total of tickets 569 were sold for the school play. they were either adult tickets or student tickets. there were 69 more stud
makkiz [27]
------------------------------------------
Define adult and student tickets
------------------------------------------
Let the number of adult tickets be x
Adult tickets = x
Student tickets = x + 69


------------------------------------------
Form equation and solve for x
------------------------------------------
x + x + 69 = 569         
2x + 69 = 569              ← Combine like terms
2x = 569 - 69               ← Subtract 69 from both sides
2x = 500
x = 250                         ← Divide by 2 to find x

------------------------------------------------------------------------------------
Find the number of adult tickets and student tickets
------------------------------------------------------------------------------------
Adult tickets = x = 250
Student tickets = x + 69 = 319

------------------------------------------------------------------------------------
Answer: Adult tickets = 250 ; Student tickets = 319
------------------------------------------------------------------------------------
