Answer:
Personal items=15
Step-by-step explanation:
We are given:
Total number of artifacts = 72.
We are told that 2/3 of total artifacts are shards of pottery.
We are also told that 1/8 of total artifacts are tools.
Now we will find out number of personal items by subtracting combined number of shards of pottery and tools from total number of artifacts.
Therefore, there are 15 personal items.
Answer:
Time taken = 9987.38 years
Step-by-step explanation:
We have plutonium-240 decays according to the parent function
k is the decay constant,0.00011
k = 0.00011
We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.
Q(t) = 9 g
Q₀ = 27 g
Substituting
Time taken = 9987.38 years
Answer:
to the nearest tenth
Step-by-step explanation:
find the area of the semi circle
find area of the whole shape
then subtract both areas to get shaded area
The answer is 10. 10 * 10= 100 and 10+10= 20
