Answer:
Diameter = 2 × inches
Step-by-step explanation:
Given the diameter of the smallest visible particle, 0.0002 inches, we can express this into the following scientific notation: 2 × inches.
In expressing decimal forms into scientific notation, the goal is to move the decimal point towards the right, until there is only one non-zero digit remaining towards the left-side of the decimal point. In this case, it will take 4 units towards the right of the sole non-zero digit, which is 2. Moving the decimal point towards the <u>right</u> means that 10 will have a <em>negative</em> exponent.
Therefore, the scientific notation of 0.0002 inches is 2 × inches.

Answer:
Squirrel will take 0.25 hours or 15 minutes
Step-by-step explanation:
Given:
Maximum speed of squirrel = 12 miles/hour
Distance to be covered = 3 miles
To Find:
Time taken to cover the distance = ?
Solution:
We are given the distance and speed of the squirrel and we have to find the time taken by the squirrel
We are given the formula for distance
Distance = speed * time
Now to we have the values
putting in the values
3 = 12 * time
dividing both sides by 12
0.25 hours = time
as one hour = 60 minutes
so
time = 0.25 * 60 minutes
time = 15 minutes
Squirrel will take 0.25 hours or 15 minutes
