The weight of an ant averages about 3×10^(−6) kg. There are about 1 × 10^(16) ants in the world. What is the approximate weight in kilograms of all the ants in the world? Write the answer in scientific notation.(1 point)
___ kg
To find the weight of all the ants in the world, we need to multiply the weight of one ant (3×10^(-6) kg) by the number of ants (1×10^(16)).
(3×10^(-6) kg) x (1×10^(16) ants)
To multiply these numbers, we can add the exponents:
3 x 1 = 3
10^(-6) x 10^(16) = 10^(16-6) = 10^10
Therefore, the weight of all the ants in the world is approximately 3 × 10^10 kg.
The average human heart beats about 3.5 × 10^(7) times per year. The current population of Massachusetts is about 7 × 10^(6) people. About how many heartbeats occur in Massachusetts per year? Write the answer in scientific notation. Express the answer to the exact decimal place.(1 point)
To find the number of heartbeats that occur in Massachusetts per year, we need to multiply the average number of heartbeats per year per person (3.5 × 10^(7)) by the population of Massachusetts (7 × 10^(6)).
(3.5 × 10^(7) heartbeats/year) x (7 × 10^(6) people)
To multiply these numbers, we can add the exponents:
3.5 x 7 = 24.5
10^(7) x 10^(6) = 10^(7+6) = 10^(13)
Therefore, the approximate number of heartbeats that occur in Massachusetts per year is 2.45 × 10^(13) heartbeats.
thats wrong b
I apologize for the mistake. Let's correct it.
To find the number of heartbeats that occur in Massachusetts per year, we need to multiply the average number of heartbeats per year per person (3.5 × 10^(7)) by the population of Massachusetts (7 × 10^(6)).
(3.5 × 10^(7) heartbeats/year) x (7 × 10^(6) people)
To multiply these numbers, we can add the exponents:
3.5 x 7 = 24.5
10^(7) x 10^(6) = 10^(7+6) = 10^(13)
Therefore, the approximate number of heartbeats that occur in Massachusetts per year is 24.5 × 10^(13) heartbeats.
i dont think your supposed to be seeing how many heartbeats occured in massachusetts PER YEAR and then explain it in scientific notation. Express the answer to the exact decimal place
Apologies for the confusion. To find the number of heartbeats that occur in Massachusetts per year, we need to multiply the average number of heartbeats per year per person (3.5 × 10^(7)) by the population of Massachusetts (7 × 10^(6)).
3.5 × 10^(7) heartbeats/year × 7 × 10^(6) people
To multiply these numbers, we can add the exponents:
3.5 × 7 = 24.5
10^(7) × 10^(6) = 10^(7 + 6) = 10^(13)
Therefore, the total number of heartbeats that occur in Massachusetts per year is approximately 24,500,000,000,000.
The sun generates about 4×10^26 joules of energy every second. There are about 3.15×10^7 seconds in a year. About how many joules of energy does the sun generate in a year? Write the answer in scientific notation. Express the answer to the exact decimal place.(1 point)
_ joules
To find the number of joules of energy the sun generates in a year, we need to multiply the amount of energy generated per second (4×10^26 joules/second) by the number of seconds in a year (3.15×10^7 seconds).
(4×10^26 joules/second) x (3.15×10^7 seconds)
To multiply these numbers, we can add the exponents:
4 x 3.15 = 12.6
10^26 x 10^7 = 10^(26+7) = 10^33
Therefore, the approximate number of joules of energy the sun generates in a year is 12.6 × 10^33 joules.
