Question

An adult killer whale can eat LaTeX: 4.0\times10^84.0 × 10 8 krill in a day. At that rate, how many krill can an adult killer whale eat in LaTeX: 3.65\times10^23.65 × 10 2 days?

Answer 1

1.46 x
`10^(11)` krill in 365 days.

Step-by-step explanation:

The adult killer whale eats 4.0 x
`10^(8)` (400 000 000) krill in a day.

Number of krill that the adult whale would eat in 3.65 x
`10^(2)` (365) days can be determined as;

= Number of krill eaten per day x number of days

= 4.0 x
`10^(8)` x 3.65 x
`10^(2)`

= 1.46 x
`10^(11)`

Therefore, an adult killer whale would eat 1.46 x
`10^(11)` krill in a year (365 days).
