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

Ben and his friends are having a TV marathon, and after 4 hours they have watched 5 episodes of the show. About how long will it
nata0808 [166]

Answer:

19.2 hours.

Step-by-step explanation:

There are 60 minutes in an hour.

60 x 4 = 240

There are 240 minutes in 4 hours.

Next, find out how long each episode is.

240 / 5 = 48.

48 minutes is how long each episode is.

48 x 24 = 1152

The entire season would be 1152 minutes.

1152 / 60 = 19.2.

Feel free to let me know if you need more help. :)
