A whale weigis 8x10 pounds. A goliath grouper weighs 4 x 10 pounds About how many times greater is the whale than the grouper? Give your answer in
standard form.

answer: r there any options?

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
