4 squares. "Put 1 grain of rice on the first square, 2 grains on the second square, 4 on the third square, 8 on the fourth square, and so on, doubling the number of grains each time, until all 64 squares are filled with the right number of grains. That will be my reward." How many rice grains must be given in total ?

18 x 10^18 grains of rice

a lever will balance if the mass of object 1 times its distance from the fulcrum equals the ma's of object 2 times its distance
Afina-wow [57]

If the distance between the fulcrum and the effort is increased, the distance that the effort must move the lever increases as well. Conversely, if the distance between the fulcrum and the load is decreased, the distance that the lever must move also decreases.

so we have too apply more force to pull the lever cause the distance is 1x smaller then mia lever so on mia lever we ull moree to get it to move!

10 - |3n - 2| = -9<br><br>please help :D​
lapo4ka [179]

Answer:

n =7 or n = -17/3

Step-by-step explanation:

10 - |3n - 2| = -9  (subtract 10 from both sides)

- |3n - 2| = -9 - 10

- |3n - 2| = -19   (multiply both sides by -1)

|3n - 2| = 19

(3n - 2) = 19 or (3n - 2) = -19

For (3n - 2) = 19,

3n - 2 = 19

3n = 21

n =7 (answer)

For (3n - 2) = -19,

3n - 2 = -19

3n = -17

n = -17/3 (answer)
