Answer:

3.25 pounds per acre

Step-by-step explanation:

We want to find how much pounds of seed is need per acre. In division, with a numerator and denominator, this works perfectly, with how much we need (of seed) per acre translating into $\frac{26 pounds}{3 acres}$ , with the line representing the per. We can plug this into a calculator to get 3.25 pounds per acre, or $\frac{3.25 pounds}{1 acre}$

an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14. Find the age of the spear he

Genrish500 [490]

Answer:

The age of the spear head to the nearest year is 1845 years

Step-by-step explanation:

We know that

half life time of C-14 is 5730 years

so, h=5730

we can use formula

$P(t)=P_0(\frac{1}{2})^{\frac{t}{h} }$

now, we can plug value

$P(t)=P_0(\frac{1}{2})^{\frac{t}{5730} }$

an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14

so,

$P(t)=0.80P_0$

we can plug it

$0.80P_0=P_0(\frac{1}{2})^{\frac{t}{5730} }$

now, we can solve for t

$0.80=(\frac{1}{2})^{\frac{t}{5730} }$

$\ln \left(0.8\right)=\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{5730}}\right)$

$t=-\frac{5730\ln \left(0.8\right)}{\ln \left(2\right)}$

$t=1844.647$

So,

The age of the spear head to the nearest year is 1845 years
