Answer:

40 minutes

Step-by-step explanation:

We can solve this problem through finding the proportion...

Let the time taken to travel 8 inches at the speed be x

Hence, 12:60 :: 8:x

We must multiply the extremes and the nears..

Hence,

12x=60×8

x=60×8/12

x=40 minutes

How do you write 3.5 × 10^3 in standard form?

Nutka1998 [239]

Answer:

$3500$

Step-by-step explanation:

Given the following question:

$3.5\times10^3$

To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.

Since the exponent is three, we know that the decimal point is going to move to the right THREE times.

$3.5\times10^3$
$3.5\times10^3=3.5.0.0.$
$3.5.0.0.=3500$
$=3500$

Your answer in standard form is "3500."

Hope this helps.
