What are two equivalent ratios for 8/10?

Varvara68 [4.7K]

To find this, multiply both the numerator and denominator by the same number. For example, 8 x 8 =64, and 10 x 8=80, so 64/80 would be an example of an equivalent ratio. Others could be 16/20 or 48/60. Hope this helps.

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest ten

Leona [35]

Answer:

$t \approx 50.4\,min$

Step-by-step explanation:

The time constant of the element X is:

$\tau = \frac{13\,min}{\ln 2}$

$\tau = 18.755\,min$

The decay function has the following form:

$\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }$

$t = -\tau \cdot \ln \frac{m}{m_{o}}$

$t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)$

$t \approx 50.4\,min$
