at breakfast his morning Lowell spilled 2.49 g of his cereal, while his brother Andy spilled 5,704 mg of cereal. Their mother said whomever spilled the most cereal would have to wash the breakfast dishes. Who had to wash the dishes? What is the difference in the mount the brothers spilled.

Andy had to wash the dishes because he spilled 3214 mg more than Lowell.

Step-by-step explanation:

First, you have to find how many mg are in 2.49 g. 2.49g=2490mg So, Lowell spilled 2490 mg, and Andy spilled 5704 mg. Since Andy spilled more, he had to wash the dishes. The difference between the numbers is 5704-2490=3214 mg

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

practice. practice. practice.
