Answer:
A reality check quickly reveals that even if "eats" were spelled properly, the statement would still be nonsense.
Step-by-step explanation:
(40,000 pounds / 80 years) = (4,000 pounds / 8 years) = 500 pounds per year
500 pounds of bread per year = an average of a little more than 1-1/3 pound of bread per day, every day of a person's life. My reality meter says that this is a bit much, especially in the USA.
Answer: Triangle B
Step-by-step explanation: Congruent just means which shape matches the others, like as you see D and F are congruent as well as A, C, and E.
Answer:
A(t) = 300 -260e^(-t/50)
Step-by-step explanation:
The rate of change of A(t) is ...
A'(t) = 6 -6/300·A(t)
Rewriting, we have ...
A'(t) +(1/50)A(t) = 6
This has solution ...
A(t) = p + qe^-(t/50)
We need to find the values of p and q. Using the differential equation, we ahve ...
A'(t) = -q/50e^-(t/50) = 6 - (p +qe^-(t/50))/50
0 = 6 -p/50
p = 300
From the initial condition, ...
A(0) = 300 +q = 40
q = -260
So, the complete solution is ...
A(t) = 300 -260e^(-t/50)
