Answer:
Step-by-step explanation:
the constant drain of water is C:
C= (1000-940)/10 = 6 gallons per minute
after x minutes : 1000- 6x ( water left in the tank after x minutes)
for 5 minutes: 1000-6(5)=970
after 20 min.: 1000-6(20)=880
after 30 min.: 1000-6(30)=820
after 27 min.: 1000-6(27)= 838
the rate of flow of water is 6 gallon per minute

Answer:
The relationship between the arc length (S), the radius (r), and the angle subtended by the arc at the center (theta), is given by the formula S = r(theta), when theta is in radians. And is given by ((theta)/360) x 2pi r, when theta is in degrees.

Answer: There are 646,646 different selections.
The library is going to select 10 books from a set of 22 books. There are a lot of different possibilities. This is a combination problem.
The standard notation is 22 C 10, this means that we are selecting 10 from 22 and the order doesn't matter. Most calculators will do this for you.
If you want to do the work by hand, evaluate: 22! / (10! x 12!)
Either way you will get 646,646 possibilities.<span />
