-4/7x8/5=-32/35. If you have any other fraction questions I will be happy to help I love solving fractions. Hope this helps :)
Step-by-step explanation:
got to multiply 2 by (1/8)
(2/1)×(1/8)=2/8
simplify it. for top and bottom there are multiples of 2 in common so divide 2 on top and bottom
(2÷2)/(8÷2)=1/4
Answer:
1/5
Step-by-step explanation:
Answer:
They are right, the time calculated using the exponential decay equation is 1948.6 years.
Step-by-step explanation:
The time can be calculated using the exponential decay equation:
(1)
<u>Where</u>:
N(t): is the quantity of C-14 at time t
N₀: is the initial quantity of C-14
λ: is the decay constant
The decay constant is:
(2)
By entering equation (2) into (1) and solving for t, we have:

Therefore, the time of the scrolls estimated by the archeologists is right, since the time calculated using the exponential decay equation is 1948.6 years.
I hope it helps you!
(B) carlos: 920 - 300 = 680
Rita: 980 - 375 = 680
(Sorry i could only answer B :(
