Answer:

- 12

Step-by-step explanation:

The sea level serves as a reference point and may be used to describe objacetsvir positions above or below it. Therefore, the sea level is regarded as a zero point or level. Hence, objects below are describes to be at a negative distance while those above are assigned the positive sign. Hence, for a position which is 12 km below sea level, then the object is said to be at a distance of - 12 km (below sea level takes the negative sign.)

DENIUS [597]
So assuming that youmeans there were 35 MORE rose plants than sunflower seeds, then

Rose:Sunflower =8:3

rose=sunflower+35
therefor

8 units=rose
3 units=sunflowers

rose-35=sunflower
8unit-35=3unit
5unit-35=0
5unit=35
therefor
35=5unit
divide by 5
7=1unit


so 8 units of roses

7 times 8=56

3 units of sunflowers
3 times 7=21

rose=56
sunflower=21

The half life of a certain tranquilizer in the bloodstream is 36 hours. How long will it take for the drug to decay to 87% of th
Fudgin [204]

<u>Finding the Decay constant(λ):</u>

λ = 0.693 / (half-life)

we are given that the half-life is 36 hours

λ = 0.693 / (36)

λ = 0.01925 /hour

<u>Time taken for 87% decay:</u>

Since decay is first-order, we will use the formula:

t = \frac{2.303}{decay constant}log(\frac{A_0}{A} )

Where A₀ is the initial amount and A is the final amount

Let the initial amount be 100 mg,

the final amount will be 87% of 100

Final amount = 100*87/100 = 87 mg

<em>Replacing the values in the equation: </em>

<em />t = \frac{2.303}{0.01925}log(\frac{100}{87} )<em />

<em />t = \frac{2.303}{0.01925}*0.06<em />

t = 7.18 hours

<em>We used 'hours' as the unit because the unit of the decay constant is '/hour'</em>

Therefore, the drug will decay to 87% of initial dosage after 7.18 hours
