Let the integers be x - 1, x and x + 1, then
x - 1 + x + x + 1 = -42
3x = -42
x = -42/3 = -14
The three consectutive integers are -15, -14 and -13
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:
9) C: x=4, y=2rt3
10) A: XY/YZ
11) A: XY/XZ
Step-by-step explanation:
9 - that is a 30, 60, 90 triangle so the ratios will be a, root3a, 2a
10 - tan = opposite / adjacent
11 - cos = adjacent/hypotenuse
Answer:
3
Step-by-step explanation:
If you divide the total cost (y) by the number of balloons (x) you get 3 for all of them
