Answer:
5/8
Step-by-step explanation:
1/4=2/8
2/8+1/8=3/8
8/8-3/8=5/8
When the dept of the water is 3/5 of the height of the cone, the radius of the water's surface is 3/5 of the radius of the cone: 1.2 ft. The rate of change of depth is equal to the rate of change of volume divided by the area of the surface:
dh/dt = (dV/dt)/A = (dV/dt)/(π·r²)
= (3/2 ft³/s)/(π·(1.2 ft)²)
= 25/(24π) ft/s ≈ 0.3316 ft/s
Answer: J + 5 = 1 + 2(B - 2)
