Find the quotient: –10/19÷(−5/7)

Semmy [17]

Answer:

14/19

Step-by-step explanation:

Note that there are two " - " signs here. Thus, the end result will be " + "

We move from left to right, obtaining first 10/19 divided by (5/7):

----- ÷ (5/7)

To divide by (5/7), invert (5/7) and then multiply. We get:

10 7 2(7)

----- * ----- = ------- = 14/19

=$165

total amount of money sold

If you can explain your answer that’d be great!! Thank you!

Rasek [7]

Answer:

$A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}$

Step-by-step explanation:

This half life exponential decay equation goes by the formula:

$A(t)=A_{0}e^{kt}$

Where

$k=\frac{ln(\frac{1}{2})}{Half-Life}$

Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:

So,

$k=\frac{ln(\frac{1}{2})}{Half-Life}\\k=\frac{ln(\frac{1}{2})}{22}$

Now

$A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}$

third choice is correct.
