(d) If the perimeter of a rectangle is 32, then the length is 13 and the width is 3.

Stells [14]

Answer:

length = 10
width = 6

Step-by-step explanation:

Any pair of dimensions that total 16 will give a rectangle with a perimeter of 32.

P = 2(L +W)

32 = 2(L +W)

16 = L +W . . . . . . . divide by 2

This is true for L = 13 and W = 3. It is also true for L = 10 and W = 6, or any other pair of dimensions x and (16-x).

A scientist has 100 milligrams of a radioactive element. The amount of radioactive element remaining after t days can be determi

grandymaker [24]

The mass of the first shipment at time t is
$m_{1}=100( \frac{1}{2} )^{ \frac{t}{10}}$

The mass of the second shipment at time t is
$m_{2}=100( \frac{1}{2} )^{ \frac{t-3}{10} }$

At time t, the ratio of m₁ to m₂ is
$\frac{m_{1}}{m_{2}} = \frac{100}{100}. \frac{(1/2)^{t/10}}{(1/2)^{(t-3)/10}} \\ = \frac{(1/2)^{t/10}}{(1/2)^{t/10}}. \frac{1}{(1/2)^{-3/10}} \\ = (1/2)^{3/10} \\ = 0.8123$

Therefore as a percentage,
$\frac{m_{1}}{m_{2}} =100*0.8123 = 81.23 \%$

Answer: B. 81.2%
