Answer: 3
Step-by-step explanation:
if you use 3 then it is; 10+3=13 and 13*2=16
His distance from one end is ' D ', and his distance from the other end is ' 2D '.
The distance from one end to the other end is (D + 2D) = 3D .
3D = 1,049 miles
Divide each side by 3 :
D = 1,049 / 3 = 349 and 2/3 miles .
The question doesn't tell which end he started from, and where he's headed,
so I guess you have to know that this is the Iditerod race, it STARTS in Anchorage,
and it ENDS in Nome.
He is ' 2D ' from Anchorage, so he has completed [ 2 x (349 and 2/3 miles) ] =
699 and 1/3 miles.
Rounded to the nearest mile, that's 699 miles.
True.
Example: 34^0 is 34
The tower is 75 feet, the wire is 20 feet below the top so the wire is 55 feet above the ground.
The length of the wire is the hypotenuse of a right triangle.
Using the law of cosine:
Cos(angle) = Adjacent leg / Hypotenuse.
Cos(46) = 55 / x
X = 55/cos(46)
x = 79.2 feet
You would receive a discount of 25% because 25% of 40 is 30 and you got 10 dollars off.
