Answer:
An adult male blue whale is 18.7 times heavier than an adult male African elephant.
Step-by-step explanation:
As the weight of an adult male African elephant weighs about
- [tex]9.07\:\times\:10^3[/tex] kg
And the weight of an adult blue whale is
- [tex]1.7\:\times\:10^5[/tex] kg
Determining the ratio of adult male African elephant to the weight of an adult blue whale as:
[tex]\:\:\frac{1.7\:\times\:10^5}{9.07\:\times\:10^3}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]=\frac{10^{5-3}\times \:1.7}{9.07}[/tex]
[tex]=\frac{10^2\times \:1.7}{9.07}[/tex]
As [tex]10^2\times \:1.7=170[/tex], So
[tex]=\frac{170}{9.07}[/tex]
[tex]=18.74310\dots[/tex]
Round the answer to the nearest tenth
[tex]=18.7[/tex]
Therefore, an adult male blue whale is 18.7 times heavier than an adult male African elephant.
