Answer:
8.898% will remain after 20000 years.
Step-by-step explanation:
First week need to know the half-life of carbon-14.
In this case it's 5,730 years.
There are calculators available online. (I'm too lazy to run through the equation.) 8.898% will remain after 20000 years.
Answer:
First one equals -15
Second one equals -3
Step-by-step explanation:
(-4)*2 - 7
= (-8) - 7
= (-15)
(-4) + 1
= (-3)
Hopefully this helps.
Answer:
225 sq inches.
Step-by-step explanation:
If two more layers are added on it would be 225 because 5*7*7=225
It's the same because you're trying to find net price (end price)
You're going to take in both scenarios 100%-15%= 85%
You're always going to be paying only 85% of the price.
Sure you could as long as you have the point.
for example let's say the slope is 2 and the point we are given is (4,4)
we know that:

plug in the values given
x=4
y=4
m=2

b, the y intercept equals -4.
so:

in this case
