Answer:
Step-by-step explanation:
<u>80:50:20 or 8:5:2. 8 ÷ 15 * 30 = 16 = 16 - 10 = 6. This is the solution.</u>
- Option A. 30 + 10 = 40. Incorrect. The solution is unequal to this.
- Option B. 30 + 9 = 39. Incorrect. The solution is unequal to this.
- Option C. 30 + 8 = 38. Incorrect. The solution is unequal to this.
- Option D. 30 + 7 = 37. Incorrect. The solution is unequal to this.
- Option E. 30 + 6 = 36. Correct. The solution equals this answer.
<u>Option E will be the answer.</u>
83x + P = 83x + Q <em>subtract 83x from both sides</em>
P = Q
The equation has no solution for P different Q (P ≠ Q).
This problem is better understood with a given figure. Assuming
that the flight is in a perfect northwest direction such that the angle is 45°,
therefore I believe I have the correct figure to simulate the situation (see
attached).
Now we are asked to find for the value of the hypotenuse
(flight speed) given the angle and the side opposite to the angle. In this
case, we use the sin function:
sin θ = opposite side / hypotenuse
sin 45 = 68 miles per hr / flight
flight = 68 miles per hr / sin 45
<span>flight = 96.17 miles per hr</span>
16 is correct
and so is negitive 8
The factors of 15 are 1, 3, 5 and 15. Now, as 1 is neither prime and nor a composite number (1 is not Prime because for a number to be a prime, it should have exact 2 factors i.e. 1 and itself, but 1 has only one factor. Therefore 1 is not prime.)
So the smallest prime factor of 15 is 3.
Hope this helped! :)
