Answer:
66 inches
Step-by-step explanation:
v² = 55² + 26² - 2(55)(26) · cos 103°
v² = 3025 + 676 - [2860 · cos 103°]
v² = 3701 - (-643.4)
v² = 4344.4
v = ≈ 66
Answer:
12 for 7$
Step-by-step explanation:
The equation for the distance d from Dallas, in terms of h, the number of hours Joe has traveled is <u>d = 320 - 69h</u>. Hence, <u>option B</u> is the right choice.
The total distance that Joe needs to cover to travel to Dallas = 320 miles {As he lives 320 miles away from Dallas}.
The distance that Joe covers after traveling for h hours at an average speed of 69 miles per hour = 69h {as Distance = Speed*Time}
Therefore, the distance left to cover by Joe, that is the distance from Dallas d can be written as the difference between the total distance needed to be covered and the distance Joe already covered.
Thus the equation is d = 320 - 69h.
Thus, the equation for the distance d from Dallas, in terms of h, the number of hours Joe has traveled is <u>d = 320 - 69h</u>. Hence, <u>option B</u> is the right choice.
