ololo11 [35]

Answer: $43.54 ft^3/min$

Step-by-step explanation:

Given

Thickness of oil slick=0.07 foot

radius of slick=110 ft

$\frac{\mathrm{d} r}{\mathrm{d} t}=0.9 ft/s$

Let V be the volume of oil slick

so, $V=0.07\pi \cdot r^2$

rate of oil flowing is

$\frac{\mathrm{d} V}{\mathrm{d} t}=0.07\times 2\pi \cdot r\frac{\mathrm{d} r}{\mathrm{d} t}$

$\frac{\mathrm{d} V}{\mathrm{d} t}=0.07\times 2\pi \times 110\times 0.9=43.54 ft^3/min$

Flauer [41]

Answer:

Step-by-step explanation:

Since it says 'each time ' you would say 15x and 25x. Since that isnt an answer you add them together and get 40x. That eliminates B and C. Next you would do the other side of the equation. He only pays the membership one time but pays for parking every time he goes so it would be 110 and 10x
