The weight of an ant averages about 3×10−6 kg. There are about 1×1016 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)
To find the approximate weight of all the ants in the world, we can multiply the average weight of an ant by the total number of ants.
Weight of an ant: 3×10^-6 kg
Number of ants: 1×10^16 ants
Weight of all the ants = (3×10^-6 kg) * (1×10^16 ants)
To simplify the product, we can add the exponents:
(3 * 1) * (10^-6 * 10^16) = 3 * 10^(-6+16) = 3 * 10^10
Therefore, the approximate weight of all the ants in the world is 3×10^10 kilograms.
To find the approximate weight of all the ants in the world, we first need to multiply the weight of a single ant by the total number of ants.
Step 1: Multiply the weight of a single ant by the total number of ants
3 × 10^(-6) kg × 1 × 10^16 ants
Note: Multiplying numbers in scientific notation involves multiplying the coefficients and adding the exponents.
Step 2: Multiply the coefficients
3 × 1 = 3
Step 3: Add the exponents
10^(-6) + 10^16 = 10^(16-6) = 10^10
Therefore, the approximate weight of all the ants in the world is 3 × 10^10 kg.
To find the weight of all the ants in the world, we can multiply the average weight of an ant by the total number of ants:
Weight of an ant = 3 × 10^(-6) kg
Number of ants = 1 × 10^16
Weight of all the ants = (3 × 10^(-6) kg) × (1 × 10^16) = 3 × 1 × 10^(-6) × 10^16 = 3 × 10^(16-6) = 3 × 10^10
Therefore, the approximate weight in kilograms of all the ants in the world is 3 × 10^10 kg, written in scientific notation.
