Answer:

The slope is -3 and the y intercept is -2

Step-by-step explanation:

3x + y = -2

Solve for y

Subtract 3x from each side

3x-3x + y =-3x -2

y = -3x-2

This is in slope intercept form

y = mx+b  where m is the slope and b is the y intercept

The slope is -3 and the y intercept is -2

One thousand tonnes (1000 t, one t equals 10 cubed kg) of sand contains about a trillion (10 super 12) grains of sand. How many
Phantasy [73]

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 = 6.022\times 10^{23} sand particles

Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is

\frac{6.022\times 10^{23}}{10^{12}}=6.022\times 10^{11}

Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of 6.022\times 10^{11} trillion sand particles is

Mass=1000\times 6.022\times 10^{11}=6.022\times 10^{14}tonnes

Part 2)

Since it is given that volume of 1 sand particle is 1.0mm^{3} thus the volume of 1 mole of sand is volume of 6.022\times 10^{23} sand particles

Thus volume of 1 mole is V=1.00\times 10^{-18}km^{3}\times 6.022\times 10^{23}=6.022\times 10^{5}km^{3}

Now since the Area of united states is A=3.6\times 10^{6}mile^{2}=5.8\times 10^{6}km^{2}

Thus the depth of the sand pile is

Depth=\frac{Volume}{Area}=\frac{6.022\times 10^5}{5.8\times 10^6}=0.10387km=103.8meters
