What happens when a beach is in equilibrium? A. more sediment is deposited than is washed away
B. more sediment is washed away than is deposited
C. no sediment is deposited or washed away
D. the same amount of sediment is deposited as is washed away

it should be all of them because it asks if you included all of those in your answer

explanation:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
