A blue whale can eat 3 x 10^8 krill in a day. All of that krill weighs approximately 6.3 x 10^9 decigrams. About how much does each krill weigh? Give your answer in standard form

Respuesta :

calculista

Answer:

21 decigrams

Step-by-step explanation:

we know that

To find out the weight of each krill, divide the total weight of the krill by the number of krill

[tex]\frac{6.3*10^{9}}{3*10^{8}}[/tex]

Remember that

To divide two numbers in scientific notation, divide their coefficients and subtract their exponents

[tex]\frac{6.3*10^{9}}{3*10^{8}}=(\frac{6.3}{3})*10^{(9-8)}=2.1*10=21\ decigrams[/tex]
