Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 40 gram sample of a substance that's
used for drug research has a k-value of
0.1472.
Enter the correct answer.
N=Noe
DONE
No - initial mass (at time t = 0)
OOC
0
OO
N = mass at timet
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

c

it would be c

$649.60

step-by-step explanation:

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
