Answer:
21 miles per hour
Step-by-step explanation:
Let w represent the wind speed. Then the travel time is ...
400/(329 +w) = 352/(329 -w)
400(329 -w) = 352(329 +w)
(352+400)w = 329(400 -352)
w = (400 -352)/(400 +352)·329 = 48/752·329 = 21
The wind speed is 21 miles per hour.
Answer:
Midpoint for A is (1,5) and for B it is (2.5,4.5)
Step-by-step explanation:
To get the midpoint you add the x coordinates and divide by 2 and then the y coordinates and divide by 2.
X = (3 + -1)/2 y = (8+ 2)/2
=2/2 = 1 10/2=5
Answer:
10). m∠x = 47°
11). x = 30.96
Step-by-step explanation:
10). By applying Sine rule in the given triangle DEF,
Sin(x) = 
Sin(x) = 0.7309
m∠x = 
m∠x = 46.96°
m∠x ≈ 47°
11). By applying Sine rule in ΔRST,
x = 
x = 30.96
Answer:
950 miles
the problem states that Mr. Lopez drove 77 more miles so just add 873+77 to get 950 miles
