Question

3
the average weight of a bumblebee is about 0.00025 pounds. the average weight of a blue whale is about 330,000 pounds.
statement\tt/f?
the weight of a bumblebee can be estimated using 3 x 10^(-4) pounds.\tf
the weight of a blue whale can be estimated using 3 x 10^5 pounds.\tt
the weight of a blue whale is about 3 x 10^9 times greater than the weight of a bee.\tf
rewrite the false statement to make it true:

Explanation:

Step1: Check first statement

The average weight of a bumble - bee is 0.00025 pounds = 2.5×10⁻⁴ pounds, not 3×10⁻⁴ pounds. So it's false.

Step2: Check second statement

The average weight of a blue whale is about 330000 pounds = 3.3×10⁵ pounds, close to 3×10⁵ pounds. So it's true.

Step3: Check third statement

Let the weight of a bumble - bee \(w_b = 2.5\times 10^{-4}\) pounds and the weight of a blue whale \(w_w=3.3\times 10^{5}\) pounds. The ratio \(\frac{w_w}{w_b}=\frac{3.3\times 10^{5}}{2.5\times 10^{-4}}=\frac{3.3}{2.5}\times10^{9}=1.32\times 10^{9}\), not \(3\times 10^{9}\). So it's false.

Step4: Rewrite false statements

First false statement: The weight of a bumblebee can be estimated using \(2.5\times 10^{-4}\) pounds.
Third false statement: The weight of a blue whale is about \(1.32\times 10^{9}\) times greater than the weight of a bee.

Answer:

The weight of a bumblebee can be estimated using \(2.5\times 10^{-4}\) pounds.
The weight of a blue whale is about \(1.32\times 10^{9}\) times greater than the weight of a bee.
