Answer:
540.6 mi
Step-by-step explanation:
The angle of depression = angle of elevation = 6°
Let x = the distance to the runway.
tan 6 = 30000/x
xtan 6 = 30000
x = 30000/tan 6 =285430.9 ft
285430.9336.../5280 = 540.6 mi
His number line is incorrect, or he plotted the point incorrectly. We know that the numbers on a number line get bigger as we get farther and farther away from zero on both sides. So -4 being closer to zero than -2 is impossible on a perfect number line. Thus, he either needs to check his counting, or check if he plotted the right number.

We know that
density=mass/volume--------> volume=mass/density
step 1
find the volume of water
mass=700 kg
density of water=1000 kg/m³
volume of water=mass/density-----> 700/1000----> 0.70 m³
step 2
find the volume of ice
mass=450 kg
density of ice=916 kg/m³
volume of ice=mass/density-----> 450/916----> 0.49 m³
volume of water is 0.70³
volume of ice is 0.49 m³
<span>volume of the mixture is (0.70+0.49)-----> 1.19 m</span>³
the answer is
the volume of water is 0.70 m³
