L = rc
= 26.9 * 9*3.14 / 5
= 152.04 to nearest 1/100
Answer:
2998 ; 17%
Step-by-step explanation:
Given the function:
t(c)=-3970.9(ln c)
c = % of carbon remaining ; t = time
1.) c = 47% = 47/100 = 0.47
t(0.47) = - 3970.9(In 0.47)
t = - 3970.9 * −0.755022
t = 2998.119
t = 2998
B.)
t = 7000
t(c)=-3970.9(ln c)
7000 = - 3970.9(In c)
7000 / - 3970.9 = In c
−1.762824 = In c
c = exp(−1.762824)
c = 0.1715596
c = 0.1715596 * 100%
c = 17.156% ; c = 17%
10/9 or 1 1/9
I suggest using an app called Photomath for equations
Well first you would do 5 / 30 which makes 6 then you would 6 times 3 equals 18. So she would make 18 loaves of bread.
