Answer:
87km
Step-by-step explanation:
Volume is proportional to radius cubed, so radius is proportional to the cube root of volume.
Increase volume by a factor of 10^6 and radius increases by a factor of the cube root of 10^6, which is 10^(6/3) = 10^2 = 100.
100 * 0.87 km = 87 km
The answer would be 30 ft below sea level
X = 12 because x+3 is equal to 15
A= 99 because 11x10=100-10 will equal 97
The answer: the second one y= -2x+7
