Answer:
Proportional
Unproportional
Step-by-step explanation:
85 -6 = 79
79 -6 = 73
73 -6 = 67
1.49 +10 = 1.59
1.59 + 30 = 1.89
Answer:
Independent.
Step-by-step explanation:
Considering the surface area of the spherical ballon, it will take 7 seconds for the the balloon to fully inflate.
<h3>What is the surface area of a sphere?</h3>
The surface area of a sphere of radius r is given by:

In this problem, the surface area is of
cm², hence the radius in cm is found as follows:





r = 14 cm.
The radius start at 0 cm, inflating at a rate of 2 cm/s, hence it will take 7 seconds for the the balloon to fully inflate, as 14 cm/(2 cm/s) = 7 s.
