For 1 Quarter:

$Amount\ paid\ in\ tuition=\$729\\\\Amount\ paid\ in\ fees=\$22\\\\Total\ amount\ paid\ in\ 1\ Quarter=Amount\ paid\ in\ tuition+Amount\ paid\ in\ fees\\\\Total\ amount\ paid\ in\ 1\ Quarter=729+22\\\\Total\ amount\ paid\ in\ 1\ Quarter=\$ 751$

'Polonium-210 is a radioactive substance with a half-life of 138 days. If a nuclear

Tatiana [17]

Answer:

59.0891 g (rounded to 4 decimal places)

Explanation:

Half-life time of a radioactive substance is the time for half of the substance to decay.

Thus, the amount of the radioactive substance that remains after a number n of half-lives is given by:

$A=A_0\cdot (1/2)^n$

Where:

A is the amount that remains of the substance after n half-lives have elapses, and

A₀ is the starting amount of the substance.

In this problem, you have that the half-live for your sample (polonium-210) is 138 days and the number of days elapsed is 330 days. Thus, the number of half-lives elapsed is:

330 days / 138 days = 2.3913

Therefore, the amount of polonium-210 that will be left in 330 days is:

$A=310{g}\cdot (1/2)^{2.3913}=59.0891g$

Solve 1/5 (x+3)=−(2x+3)

Rasek [7]

Answer:

Step-by-step explanation:

just simplify the LHS first.

You can either multiply 1/5 by (x+3) and then solve

multiply both sides by 5 to get rid of 1/5 on LHS

I will multiply by 5

(x+3)= -10x-15 ( 5*1/5(x+3)= -5(2x+3)

now rearrange the equation

x+3=-10x-15

-10x-15-x-3=0

-11x-17=0

-11x=17

x= -17/11
