Answer:
3√29
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
Distance
Answer:
360 miles
Step-by-step explanation:
let speed of plane be x
speed of wind be c
Also note D = RT, where
D is distance and R is rate and T is time
<u>For First Leg:</u>
we can write:
(x - c) * 2 = D
2x - 2c = D
<u>For Second Leg:</u>
we can write:
(x+c)*1.5 = D
1.5x + 1.5c = D
We can equate and write:
2x - 2c = 1.5x + 1.5c
0.5x = 3.5c
We know Speed of Wind, c, is 30, so we have:
0.5x = 3.5(30)
0.5x = 105
x = 105/0.5 = 210 [speed of airplane]
We know distance is
D = 2x - 2c
D = 2(210) - 2(30)
D = 420 - 60
D = 360 miles
The distance is 360 miles
Answer:
awh happy holidays to you too!! and ty for this
X+6y=12
6y=12-x
y=12/6- x/6
y=(-1/6)(x)+2
Answer: True
Step-by-step explanation:
Cost = 15 + 3t
22.5 = 15 + 3(2.5)
22.5 = 15 + 7.5
22.5 = 22.5 <— true
