Answer:
A. Plane B because it was 9.33 miles away
B. 48 units
Step-by-step explanation:
A. Since the airplanes fly at an angle to the runway, their direction forms a triangle with the runway with their height above the ground as the opposite of the angle and their distance from the airport as the hypotenuse.
So for airplane A with 44° angle of departure,
sin44° = y/h where y = height above the ground and h = distance from airport
So h = y/sin44° = 6/sin44° = 8.64 miles
So for airplane B with 40° angle of departure,
sin40° = y/H where y = height above the ground and H = distance from airport
So H = y/sin40° = 6/sin40° = 9.33 miles
Since airplane B is at 9.33 miles away from the airport whereas airplane A is 8.64 miles from the airport, airplane B is farther away.
B. We know that scale factor = new size/original size
Our scale factor = 4 and original size = 12 units. So,
new size = scale factor original size = 4 × 12 = 48 units.
The model that represents 0.30+0.03 is A.

Answer:
The answer to your question is letter C
Step-by-step explanation:
Equations
x + 4y = 10
5x + 10y = 20
Process
1.- Substitute all the options in both equations and evaluate them
a) x = 3, y = 2 This option is incorrect
(3) + 4(2) = 10 3 + 8 = 10 11 ≠ 10
5(3) + 10(2) = 20 15 + 20 = 20 35 ≠ 20
b) x = 2, y = -3 This option is incorrect
(2) + 4(-3) = 10 2 -12 = 10 -10 ≠ 10
(2) + 10(-3) = 20 2 - 30 = 20 -28 ≠ 20
c) x = -2, y = 3 This is the right answer
(-2) + 4(3) = 10 -2 + 12 = 10 10 = 10
5(-2) + 10(3) = 20 -10 + 30 = 20 20 = 20
d) x = 3, y = -2 This option is incorrect
(3) + 4(-2) = 10 3 - 6 = 10 - 3 ≠ 10
5(3) + 10(-2) = 20 15 - 20 = 20 -10 ≠ 10
