An element with mass 670 grams decays by 27.3% per minute. how much of the element is remaining after 9 minutes, to the nearest 10th of a gram?

38.0 grams

Step-by-step explanation:

The exponential decay equation with rate of decay r in time period x is given by :-

, A is the initial value .

Given: The initial mass of element=  670 grams

Rate of decay= 27.3%=0.273

Now, the function represents amount of element after x minutes is given by ;-

Now, the function represents the amount of element after 9 minutes is given by ;-

Hence, 38.0 grams of element remains after 9 minutes.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
