Maya used this equation: y = 8.65x, where y represents pounds of food collected and x represents number of weeks passed.
Millicent recorded her progress in a journal entry: I weighed my donations at the end of every
three weeks, and every three weeks I had 27.3 more pounds of food.
Myron charted his collections with this table of values:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

60 for the first and 130 for the second

step-by-step explanation:

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
