How much of a radioactive kind of calcium will be left after 10 days if the half-life is 5 days
and you start with 64 grams?
me !

16 g

Step-by-step explanation:

We can solve this with the Radioactive Half Life Formula:

Where:

is the final amount of radioactive calcium

is the initial amount of radioactive calcium

is the time elapsed

is the half life of radioactive calcium

Solving with the given data:

 This is the amount of radioactive calcium left

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
