carbon-14 is an element that loses about 10% of its mass every millennium (i.e., 1000 years). A sample of carbon-14 has 600 gram s. write a function that gives the sample’s mass in grams, S(t), t millennia from today.
2 answers:
Answer:
S(t) = 600/(0.9^t)
Step-by-step explanation:
Current mass: 600 grams
If every millennium loss 10% of its mass, it retains 90%, so a millennium ago the mass was: 600/0.9 = 666.67 grams; two millennia it was: 666.67/0.9 = 600/(0.9^2) = 740.74, and so on.
Then, the explicit formula is:
S(t) = 600/(0.9^t)
where t refers to millennia from today.
Answer:
1000-100(T)
Step-by-step explanation:
1000

Solution: Find the relationship among the 3 sides and solve for the unknown.
First side = x
second side = x + 3
third side = 3x - 10
x + x + 3 + 3x - 10 = 23
5x - 7 = 23
5x = 30
x = 6 <========== shortest side

138 short sleve shirts
step 1) add up the ratio of short to long sleve shirts: 3 + 7 = 10
step 2) divide the total # of shirts by 10: 460 / 10 = 46
step 3) because you are finding how many short sleeve shirts are sold, you multiply 46 x 3 = 138 short sleave shirts
