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

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

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

Solve for x: 9x - 3 - 8x = 7 - x O O A. X=-7 O B. x = -2 D c. x=4 (0) O D. X = 5.

Answer:

D. x = 5

Step-by-step explanation:

Add x+3 to both sides and simplify.

9x -3 -8x +(x +3) = 7 -x +(x +3)

2x = 10 . . . . . simplify

x = 5 . . . . . . . divide by 2

As you can see, the expression we chose to add (x+3) is the one that results in variable terms being separated from constant terms after simplification.
