Well I would solve it but where's the problem?
This type of situation applies first order type of equation. In this case, the equation is ln( A0/A1) = kt. A is the number of bacteria cultured. A0 is equal to 150. when A1 is 300, t is 20 minutes. that is ln (150/300) = k *20 the other condition is represented by ln (A0/1200) = 60k. k is equal to -0.0347. hence the first order equation is equal to ln (150/A1) = -0.0347 t
I think letter A because on area you multiply the outside but if you’re doing perimeter you do the inside.
Answer:
1607
Step-by-step explanation:
The mean (or average) of a data set is the sum of all of the data divided by the number of data in the set. In this case, that would be:
(1606 + 1607 + 1606 + 1607 + 1607 + 1609) / 6
= 9642 / 6
= 1607
Answer:
8 red haired and 42 brown haired
Step-by-step explanation:
I chose a random number to start off with (which is 8) and I multiplied it by 5.
8•5=40 and then you have to add 2, so you get 42.
42+8 = 50
The equation would be (5x+2)+x where 'x' is the number of people with red hair.
