Asample of an unknown chemical element naturally loses its mass over time. the relationship between the elapsed time t, in months, since the mass of the sample was initially measured, and its mass, m(t), is modeled by the following function: m(t)=120(81/625)t complete the following sentence about the rate of change in the mass of the sample. round your answer to two decimal places.
the mass of the sample decays by a factor of (3)/(5) every ? months

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

is it 35

step-by-step explanation:

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
