Question

a 6.5 x 10^-8
b 6.5 x 10^8
c 6.5 x 10^7
d 6.5 x 10^-7

Answer 1

d 6.5 x 10^-7

Answer 2

the speed of light is about 671,000,000 miles per hour. How will you write this number in scientific notation?

a 6.71 x 10^-3
b 6.71 x 10^8
c 6.71 x 10^3
d 6.71 x 10^-8

Answer 3

b 6.71 x 10^8

Answer 4

suppose an average person blinks 15 times per hour. How many times does an average person blink in a year? write the answer in scientific notation (Hint: 1 year = 365 days, 1 day = 24 hours)

a 1.314 x 10^-5
b 1.314 x 10^4
c 1.314 x 10^-4
d 1.314 x 10^5

Answer 5

To find the total number of times an average person blinks in a year, we multiply the number of times they blink per hour (15 times) by the number of hours in a day (24 hours) and the number of days in a year (365 days):

15 times/hour * 24 hours/day * 365 days/year = 131,400 times/year

Writing this number in scientific notation, we get:

1.314 x 10^5

So the correct answer is d) 1.314 x 10^5.

Answer 6

what is the number 5.9 x 10^5 written in decimal notation?

a 0.000059
b 5.90000
c 5,900,000
d 590,000

Answer 7

To convert a number in scientific notation to decimal notation, we simply move the decimal point to the right or left based on the exponent.

In this case, we have 5.9 x 10^5. To convert it to decimal notation, we move the decimal point 5 places to the right, making it:

590,000

Therefore, the correct answer is d) 590,000.

Answer 8

what is the number 7.3 x 10^-8 written in decimal notation?

a 0.000000073
b 0.00000007.3
c 730,000,000
d 0.0000000073

Answer 9

To convert a number in scientific notation to decimal notation, we move the decimal point to the right or left based on the exponent.

In this case, we have 7.3 x 10^-8. To convert it to decimal notation, we move the decimal point 8 places to the left, making it:

0.000000073

Therefore, the correct answer is a) 0.000000073.
