Flying against the wind, a jet travels 4400mi in 8 hours. Flying with the wind, the same jet travels 5820mi in 6 hours. What is
Viefleur [7K]
Let J = rate of jet in still airLet W = rate of wind Distance formula:  d = rt   /   r = d/t Flying against the wind the jet flies at a rate of  J - W = 1860 miles/3 hours = 620 miles per hourFlying with the wind the jet flies at a rate of J+W = 9180 miles/9 hours = 1020 miles per hour The average of these 2 rate is the speed of the jet in still air J = (620+1020)/2 = 820 miles per hour J - W = 620  

820 - W = 620
W = 820 - 620 = 200 miles per hour The jet in still air flies at a rate of 820 mph(miles per hour)The wind speed is 200 mph(miles per hour)

A flagpole at a right angle to the horizontal is located on a slope that makes an angle of 18° with the horizontal. The flagpole
Leya [2.2K]

Answer:

height = 9.28m

Step-by-step explanation:

Sum of angle in a triangle = 180°

To find the third angle, we have

180° = 71° + 62° + α

180° = 133° + α

α = 180° - 133°

α = 47°

To find the height use sine rule

h/sin47° = 12/sin 71°

h(sin71°) = 12sin47°

h = 12sin47° / sin71°

h = 12(0.7314) / 0.9455

h = 8.7768/0.9455

h = 9.28m

The following cone has a height of 12 cm and a slant height of 16 cm. A right angle is formed between the height and radius of t
Julli [10]

Step-by-step explanation:

\pink{\large{\underline{\underline{\sf Given:-}}}}

  • \sf Height_{\blue{cone}}=12 \: cm
  • \sf Slant \: height_{\blue{cone}}=16\: cm

\pink{\large{\underline{\underline{\sf To \: find:-}}}}

  • \sf Radius_{\blue{cone}}=?

\pink{\large{\underline{\underline{\sf Solution:-}}}}

We know that,

\underline{\boxed{\sf (Radius)^2= (Slant height)^2-(height)^2}}

\sf (Radius)^2 = (16)^2-(12)^2

\sf (Radius)^2 = 256-144=112

\longmapsto \sf Radius = \sqrt{112}≈10.6\:cm
