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 can multiply the weight of one ant (3×10^-6 kg) by the number of ants (1×10^16):
3×10^-6 kg * 1×10^16 ants = 3×10^-6 * 1×10^16 = 3×1 = 3 kg.
Therefore, the approximate weight of all the ants in the world is 3 kilograms.
To find the approximate weight in kilograms of all the ants in the world, we need to multiply the average weight of an ant by the total number of ants.
Average weight of an ant = 3×10^−6 kg
Total number of ants = 1×10^16
To multiply these numbers, we multiply the coefficients and add the exponents:
(3×1) × (10^−6 × 10^16)
Simplifying the exponents:
3 × 10^(16-6)
Calculating the exponent:
3 × 10^10
Therefore, the approximate weight in kilograms of all the ants in the world is 3 × 10^10 kg.
To find the approximate weight of all the ants in the world, we need to multiply the weight of a single ant by the total number of ants.
The weight of a single ant is given as 3×10^-6 kg.
The total number of ants in the world is given as 1×10^16 ants.
To find the weight of all the ants in the world, we multiply these two values:
(3×10^-6 kg) * (1×10^16 ants)
To multiply these numbers in scientific notation, we first multiply the numerical values:
3 * 1 = 3
Then, we add the exponents of the powers of 10:
10^-6 * 10^16 = 10^(-6+16) = 10^10
Combining the numerical value and the exponent, the weight of all the ants in the world is approximately:
3 * 10^10 kg
Therefore, the approximate weight of all the ants in the world is 3 * 10^10 kg in scientific notation.
