Liam Splits $40 With The 3 Of Them Out Of $120 And Liam Has 130 Because 250-120=130

Answer:

250-\frac{120}{e}

Step-by-step explanation:

We have been given that Liam and his classmates bought a present for their teacher, evenly splitting the $120 among the 'e' of them.

This means that number of all students is 'e'. To find the cost of present for each student, we will divide 120 by e.

\text{Cost of present for each student}=\frac{120}{e}

Since Liam had $250, so we need to subtract \frac{120}{e} from 250 to get amount Liam has left:

\text{Amount Liam has left}=250-\frac{120}{e}

Therefore, our required expression would be 250-\frac{120}{e}.

Which of the following is the equation of a circle with a radius of 10 cm and center at (–3, 6)?
Volgvan

The equation of the circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have:

r=10\\(-3,\ 6)\to h=-3,\ k=6

Substitute:

(x-(-3))^2+(y-6)^2=10^2\\\\(x+3)^2+(y-6)^2=100

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

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%
