The answer is (9c/5)+32=F
It would be 3 because in a half means like cut so what is in the middle between 2 and 4? 3 so that is correct
Answer: -1
Step-by-step explanation:
Considering order of operations, multiplication takes a higher precedent than subtraction. Therefore, you do the multiplication first.
3)
The population of the bacteria after 7 hours is 230 bacteria.
An exponential function is given by:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the population of bacteria after x hours.
Given that he starts his experiment with 200 bacteria, hence
a = 200
The bacteria grow at a rate of 2% per hour, hence:
b = 100% + 2% = 1.02
The exponential equation becomes:
y = 200(1.02)ˣ
After 7 hours:
y = 200(1.02)⁷ = 230
The population of the bacteria after 7 hours is 230 bacteria.
