Answer:
<em>72 passenger planes</em>
Step-by-step explanation:
ratio passenger to cargo = 8 to 5 = 8/5
Let p = number of passenger planes.
The ratio of passenger to cargo planes that actually landed is p/45.
The ratio in general is 8/5, so 8/5 must equal p/45.
p/45 = 8/5
5p = 45 * 8
p = 9 * 8
p = 72
Answer:
120° & 240° (given the angles are between 0° and 360°)
Step-by-step explanation:
We want to find .
This means we want to know the angle(s) for which cosine has a value of .
The basic acute angle that has a cosine of is 60°. But we want to know NEGATIVE . So in which quadrants is cosine negative? Second and Third
- The rule to find 2nd quadrant angle with known acute angle is: 180 - α
- The rule to find 3rd quadrant angle with known acute angle is: 180 + α
Where α is the basic acute angle (in our case it is 60°)
So 2nd quadrant angle is 180 - 60 = 120°
and 3rd quadrant angle is 180 + 60 = 240°

Answer:
Let Q be (x,y). Then AQ = 4QB; or (x - 2) = 4(4 - x) and (y + 1) = 4(2 - y);
x - 2 = 16 - 4x; 5x = 18 [ x = 3.6. y + 1 = 8 - 4y; 5y = 7, y = 1.4, So, Q(3.6, 1.4)
