Answer:

108 ft²

Step-by-step explanation:

The length of the other side of the rectangle can be found using the Pythagorean theorem.

15² = 12² + x²

x = √(225 -144) = √81 = 9

So, the rectangle is 9 ft by 12 ft. Its area is the product of those dimensions:

A = bh

A = (12 ft)(9 ft)

A = 108 ft² . . . . area of the rectangle

The area is 180ft I think. You can do (15*12)/2 = 90. Since it’s two triangles you then do 90*2. I hope I am right

Element X decays radioactively with a half life of 8 minutes. If there are 980 grams of Element X, how long, to the nearest tent

Marysya12 [62]

Answer:

$t \approx 36.1\,min$

Step-by-step explanation:

The time constant for the isotope decay is:

$\tau = \frac{8\min}{\ln 2}$

$\tau \approx 11.542\,min$

Now, the decay of the isotope is modelled after the following expression:

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

The time is now cleared with some algebraic handling:

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

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

Finally, the time need for the element X to decay to 43 grams is:

$t = - (11.542\,min)\cdot \ln\left(\frac{43\,g}{980\,g} \right)$

$t \approx 36.1\,min$
