Answer:
6/7 and 48/56
Step-by-step explanation:
6x8=48
7x8=56
If you would like to convert the <span>angle 30° 37' 11" to decimal degrees, you can do this using the following steps:
</span>30° 37' 11" = 30 + 37/60 + 11/3600 = 108000/3600 + 2220/3600 + 11/3600 = 110231/3600 = 30.62°
The correct result would be 30.62°.
Answer:
Speed of plane in still air: 490 mile/hour
speed of wind: 70 mile/hour
Step-by-step explanation:
still speed = x wind speed = w
with wind: speed = still + wind
(x+w) * 3 = 1680 ...a
against wind: speed = still - wind
(x-w) * 4 = 1680 ...b
b-a ... 4x-4w-3x-3w = 0
x-7w = 0
x = 7w
substitution: (7w+w)*3 = 1680 8w = 560 wind speed (w) = 70
still speed (x) = 7w = 490 mile/hour
7*6= 42, 42-1= 41, and that would the anwser
