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

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

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

Please help me on this helps!!!

Answer:

2= 95 degrees

3= 25 degrees

1= 60 degrees

5= 25 degrees

4= 95 degrees

Step-by-step explanation:

2) Straight line is 180 degrees so

180-85=95 degrees

3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.

1) A triangle is always 180 degrees, 95+25=120 180-120=60

5) Its another corresponding angle to 25

4) Straight line is 180 degrees 60+25=85 180-85=95

Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4
