Answer:
for 5 hours: b is 6
for 5 minutes: b is 4
60 times more skin in 5 hours than 5 minutes
Step-by-step explanation:
I think it should be written as a x 10^b, so I'm going to answer it that way.
3 x 10^6 = 5 times 10^6
10^6 = 1,000,000, so we have 3 x 1,000,000 = 3,000, 000
5 x 10^4 = 5 times 10^4
10^4 = 10,000, so we have 5 x 10,000 = 50, 000
For part 3, divide 3 million by 50 thousand to find the scalar multiple
3,000,000/50,000 = 300/5 = 60
Answer:
The approximate number of particles of skin a human can shed in five hours can be written in the form a × 10b, where a is 3 and b is 6.
The approximate number of particles of skin a human can shed in five minutes can be written in the form a × 10b, where a is 5 and b is 4.
Humans shed approximately 60 times more particles of skin in five hours than in five minutes.
Step-by-step explanation:
In scientific notation, a number can be written in the form, a × 10b, where a is a number that must be greater than or equal to 1, but less than 10, and b is any integer.
First, write the approximate number of particles of skin a human can shed in five hours in scientific notation. This number is three million which can be written in the form a × 10b, where a is 3 and b is 6.
Next, write the approximate number of particles of skin a human can shed in five minutes in scientific notation. This number is fifty thousand which can be written in the form a × 10b, where a is 5 and b is 4.
Then, divide the approximate number of particles a human can shed in five hours by the approximate number of particles a human can shed in five minutes to find out how many times more skin is shed in five hours than in 5 minutes.
Therefore, humans shed approximately 60 times more particles of skin in five hours than in five minutes.
