Astudent uses a solution that contains 16 grams of water to conduct an evaporation experiment . at the end of one hour, the amount of water in the solution has decreased by 3.596. • at the end of two hours, the amount of water in the solution has decreased by another 4.25 %. which calculations can be used to determine the amount of water, in grams, remaining in the solution at the end of the second hour?

answer today and show and explanation and steps i need

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

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)
