Which is the better deal:
romanna [79]
$2.50 for 3.2 oz. is the better buy. multiply 1.2 by 8/3 to get 3.2 oz, which you will have to multiply $1.00 by 8/3 to get $2.67. So $1.00 for 1.2 oz is the equivalent of $2.67 for 3.2 oz.

user100 [1]

Answer:

447.44 is your final answer

Step-by-step explanation:

680 x 0.3 = 204

680 - 204 = 476

476 x 0.06 = 28.56

a sample from a mummified bull was taken from a certain place. The sample shows that 71% of the carbon-14 still remains. how old
7nadin3 [17]

Answer:

Step-by-step explanation:

Decay of carbon - 14 is exponential in nature . It decays as follows .

N=N_0e^{-\lambda t}  λ is called decay constant .

λ = .693 / T where T is half life .

Half life of carbon-14 is 5700 years

λ = .693 / T

= .693 / 5700

= 12.158 x 10⁻⁵ year⁻¹

N=N_0e^{-\lambda t}

N = .71 N₀

.71 N_0 =N_0e^{-\lambda t}

.71  =e^{-\lambda t}

Taking ln on both sides

ln .71 = - λ t

ln .71 = - 12.158 x 10⁻⁵  t

-0.3425 =  - 12.158 x 10⁻⁵  t

t = .3425 / 12.158 x 10⁻⁵

2817  years .
