kaheart [24]

Answer:

<em>A stack of 4 trillion one dollar bills will be $4\times 10^8$ meters.</em>

Step-by-step explanation:

The annual expenditure of the US federal government is approximately 4 trillion dollars.

We know, 1 trillion dollars = 10¹² dollars.

So, 4 trillion dollars $=(4\times 10^1^2)$ dollars.

Each one dollar bill is 0.0001 meters thick.

So, the total height of the stack of 4 trillion one dollar bills will be.....

$[0.0001\times(4\times 10^1^2)]meters\\ \\ =[10^-^4\times(4\times 10^1^2)]meters\\ \\ =(4\times 10^8) meters$

On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent

Jet001 [13]

Answer:

11.11%

Step-by-step explanation:

The selling price is 250

The cost price is 250-25

= 225

Therefore the gain can be calculated as follows

=250-225x/225x×100

1/9 ×100

= 0.1111×100

= 11.11%

Hence the gain is 11.11%
