An adult blue whale can eat 4.0 x 10^7 krill in a day. At that rate, how many krill can an adult blue whale eat in 3.65 x 10^2 days?



Answer :

4.0 x 10^7 = 40000000
3.65 x 10^2 = 365
40000000 x 365 = 14600000000 or 1.46 x 10^10
Hope this helps!!

Answer:

[tex]1.46\times 10^{10}[/tex] krill.

Step-by-step explanation:

We have been given that an adult blue whale can eat [tex]4.0\times 10^7[/tex] krill in a day. We are asked to find the number of krill an adult whale can eat [tex]3.65\times 10^2[/tex] days.

[tex]\text{Krill eaten in given time}=3.65\times 10^2\cdot 4.0\times 10^7[/tex]

Using exponent property [tex]a^b\cdot a^c=a^{b+c}[/tex], we will get:

[tex]\text{Krill eaten in given time}=3.65\times 4.0\times 10^{7+2}[/tex]

[tex]\text{Krill eaten in given time}=14.6\times 10^{9}[/tex]

[tex]\text{Krill eaten in given time}=1.46\times 10^{10}[/tex]

Therefore, an adult whale can eat [tex]1.46\times 10^{10}[/tex] krill in [tex]3.65\times 10^2[/tex] days.
