Answer:
the 30th number would be "82"
Step-by-step explanation:
it is adding by 3
Answer:
1432 years
Step-by-step explanation:
A(t) = I(0.5)^t/t1/2
Where t1/2 = half life = 1660
Final amount, A(t) = 0.55 of its original amount =. 0.55I
Hence, we have
0.55I = I(0.5)^t/1660
Take the log of both sides
Log(0.55) = log(0.5)^t/1660
t/1660 = log(0.55) / log(0.5)
t/1660 = 0.8624964
t = 0.8624964 * 1660
t = 1431.7441
t = 1432(nearest whole number)
2, 222 bc if 200 is in the hundreds then all the digits are the same so therefore it's 2,222
17. Sample answer: the elevation is the product of the rate and the time
18. $227.50; sample answer: $45.50 ≈ $50, and $50 × 5 = $250,
which is close to $227.50.
Hope this helps! please consider marking my answer the brainliest :)
Change into an improper fraction. 2247/10 then divide. So, 224.7. Or since you know 7/10 is 0.7 just add 224
