How much electricity is used, on average, by a security system that is always on over one year?

1 answer:

V = (4/3) pi r^3

9. V = (4/3)(3.14)(7.62)^3 = 1852.4 meters^3
10. V = (4/3)(3.14)(33/2)^3 = 18,807.0 inches^3
11. V = (4/3)(3.14)(18.4/2)^3 = 3260.1 feet^3
12. V = (4/3)(3.14)(sqrt3)/2)^3 = 2.7 cm^3
13. C = 2*pi*r ; 24 = 2 * 3.14 * r; 24/6.28 = r ; r = 3.82
V = (4/3)(3.14)(3.82)^3 = 233.4 in^3
14.V = (4/3)(3.14)(35.8)^3 = 192,095.6 mm^3

I can't read # 15 but follow the steps above.

Answer:

C) (8,12)

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\MP= (\frac{5+11}{2} )(\frac{9+15}{2} )\\MP= (\frac{16}{2} )(\frac{24}{2} )\\MP= (8,12)$

Answer ASAP: What is the set of the four consecutive integers, the largest of which is -234?

Elza [17]

I’m pretty sure the answer is -237, -236, -235, and -234. Because -234 would be the greatest of that consecutive set.
