In order to get your answer you will have to subtract 999 on both sides and then you will get your answer.

$999+k=1721$

$-999 -999$

$1721 - 999=722$

$=722$

$k=722$

Therefore your answer is "k = 722."

Hope this helps.

a 14 gram sample of substance used to preserve fruit and vegetables has a k- value of 0.1095 find substance half-life in days ro

belka [17]

Answer:

t = 6.3 days

Step-by-step explanation:

The amount of initial mass is irrelevant when finding the half-life since the remaining mass is always 1/2 of the initial mass.

$\frac { 1 } { 2 } = e ^ { ( - 0 . 1 0 9 2 t ) }$

Taking $l n$ on both the sides to get:

$ln \frac { 1 } { 2 } = -0.1092t$

$t = \frac { l n \frac { 1 } { 2 } } { -0.01092}$

$t = 6.3475$

t = 6.3 days

What is the net-price rate when a designer swimsuit, originally priced at $85 is discounted 25/60?

Gre4nikov [31]

Designer's swimsuit is originally priced at 85 dollars.
NOw, it applied a discount which is 25/60. First, let's find out how much the discount rate.
=> 25 / 60 = 0.42 * 100 = 42% is the discount.
=> 85 dollars * 0.42 = 35.7 is the discount.
=> 85 dollars - 35.7 dollars = 49.3 dollars is now the price.
