Answer with Step-by-step explanation:
Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)
Thus we have
1 mole of sand = 
sand particles
Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is
Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of 
trillion sand particles is
Part 2)
Since it is given that volume of 1 sand particle is 
thus the volume of 1 mole of sand is volume of sand particles
Thus volume of 1 mole is 
Now since the Area of united states is 
Thus the depth of the sand pile is
Answer:
because 8/4=2
Step-by-step explanation:
4/4=1
8/4=2
it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.
Answer:
The standard deviation for incomes of civil engineers from the University of Montana is abnormally low.
and
The interquartile range and the standard deviation for incomes of civil engineers from the University of Montana are equal.
In the table y is increased 70 for every 1 in x
(210/3 = 70)
on the graph for every 1 increase on x y increases by 55
(110/2 = 55)
so for the graph for x = 11, y =55 x 11 = 605
for the table for x = 11, y = 11*70 = 770
the difference is 770-605 = 165
the 2nd answer is the correct one.
H= height of rockhopper penguin.
H= 45 - 24
H= 21 inches
Answer is reasonable because you have to take the height of the emperor penguin and subtract how much taller it is from it.
