If 800g of a radioactive substance are present initially and 8 years later only 450g remain, how much of the substance will be p
artcher [175]

A=Pe^(rt)

P = 800g

t = 8 years

A = 450g

r = This is what we will try and find to start with

450=800e^(r*8)

After running the math through a calculator, we end with r = -0.07192

Now we just re-input this information into our equation: A=800e^(-0.07192*16)

A=800e^(1.15072)

Now we will re-write the equation using the negative exponent rule:

A = 800 1/e^1.15072

Combine right side:

A = 800/e^1.15072

Then do the math:

A = 253.12709836......

That will give us A = 253 (rounded to the whole number)

I hope this helps! :)

How much salt should Ilya add to 810g of water to make 10% solution? How much solution will he make? Ilya should add __g of salt
Burka [1]

Answer:

90 g of water should be added and he will make 900 g of solution.

Step-by-step explanation:

Let x g be the amount of salt Ilya add to 810g of water to make 10% solution. Then 810+x g is the amount of new solution. Thus,

810+x - 100%,

x - 10%.

Mathematically,

\dfrac{810+x}{x}=\dfrac{100}{10},\\ \\10(810+x)=100x,\\ \\8100+10x=100x,\\ \\100x-10x=8100,\\ \\90x=8100,\\ \\x=\dfrac{8100}{90}=90\ g.

So 90 g of water should be added and he will make 810+90=900 g of solution.

4(9x + 7) = x - 4<br><br> ALGEBRA 1!!
tiny-mole [99]

Hey!

-----------------------------------------------

Solution:

4(9x + 7) = x - 4

36x + 28 = x - 4

36x + 28 + 28 = x - 4 + 28

36x = x + (-32)

36x - x = x - (-24) - x

35x = -32

35x/35 = -32/35

x = -32/35

-----------------------------------------------

Answer:

x = -32/35

-----------------------------------------------

Hope This Helped! Good Luck!
