Answer:
44.1 x 10^-2
Step-by-step explanation:
Since one grain
= 7 x 10^-5
6300kg = 7 x 10^-5 x 6300
Put 6300 in standard form
7 x 10^-5 x 6.3 x 10^3
Multiply the whole numbers and add the exponents
7 x 6.3 x 10^-5 + 3
There are 44.1 x 10^-2 grains of sand in 6300kg
460 rounded to the nearest hundred is 500. 460 rounded to the nearest 10 stays 460.
x = -(h+g) / f
-fx - g = h
-fx = h + g
x = (h + g) / -f
x = -(h+g)/f
