Pipe A filled for 3 days and pipe B filled for 2 days
Both can fill: 1/3 + 1/2 = 2/6 + 3/6 = 5/6
Answer: 5/6 of a day to fill the pool
A and C are rational numbers
Answer:
, 
Step-by-step explanation:
Let be
the end of the terminal side of angle
in standard position, that is, an angle measured with respect to +x semiaxis. By Trigonometry, we know that the sine and the cosine of the angle are, respectively:
(1)
(2)
If we know that
and
, then the sine and the cosine of the angle are:




10 ÷ $3 = 9 1/3
Since she can't buy 1/3 of a spinach, the greatest amount she can buy is 9.

Answer:When electrons in atom interaction with light or photons one of the two process takes place:
1) they can absorb photons of a characteristic wavelength (which depends on the energy difference between two interacting atomic levels) and get excited to a higher energy level
2) or they can jump to a lower energy level and emit photons of the corresponding wavelength.
The type of spectrum produced when electrons in an atom undergo transitions to various levels by absorbing or emitting photons is termed as atomic spectrum.
