35.45 rounded to the nearest whole number would be 35.
Answer:
A. 7,348
Step-by-step explanation:
P = le^kt
intitial population = 500
time = 4 hrs
end population = 3,000
So we have all these variables and we need to solve for what the end population will be if we change the time to 6 hours. First, we need to find the rate of the growth(k) so we can plug it back in. The given formula shows a exponencial growth formula. (A = Pe^rt) A is end amount, P is start amount, e is a constant that you can probably find on your graphing calculator, r is the rate, and t is time.
A = Pe^rt
3,000 = 500e^r4
now we can solve for r
divide both sides by 500
6 = e^r4
now because the variable is in the exponent, we have to use a log
ln(6) = 4r
we can plug the log into a calculator to get
1.79 = 4r
divide both sides by 4
r = .448
now lets plug it back in
A = 500e^(.448)(6 hrs)
A = 7351.12
This is closest to answer A. 7,348
Answer:
Step-by-step explanation:
The basic cost of the Snout is 45.99
15% of that amount = 45.99*15/100 = <u> 6.90</u>
Total Cost 52.89
You could figure out the total cost a slightly different way.
You could set up
Cost = snout (1 + 15%)
Cost = snout(1 + 15/100)
Cost = snout( 1 + 0.15)
Cost = 45.99(1.15)
Cost = 52.89
Every kilogram is 1,000 grams, but you want 10 kilograms. You can multiply 1,000 10 times (you can also add 1,000 10 times,) giving you the answer > 10,000.
Hope this helped!
