The number of bacteria at any time t where t is number of hours is given by the equation,
At = Ao(1/2)^t/4
where Ao is the original number of bacteria. Substituting the known values from the equation,
1500 = (75000)(0.5)^t/4
The value of t from the equation is equal to 22.57 hours.
Answer:
54 inches.
Step-by-step explanation:
There is 12 inches in one feet so 12 times 4.5 is 54
(4.5 is equal to 4 1/2
Answer:
Advice that Sofiya would have given is:
1) Take least common denominator and add fraction on the left side in order to combine terms.
2) Multiply least common denominator i.e 3 to both sides in order to remove the denominator.
3) Divide both sides by 2 in order to simplify the numbers.
The standard form of the linear equation is

Equation written by Katrina:
In order to convert Katrina's linear equation into standard form Sofia must have given the following advice:
Take least common denominator in order to add fractions on the left side. The common denominator here would be 3 as 3 is the only denominator.
Adding fractions.
Multiplying both sides by
Dividing both sides by
∴ The standard form of the linear equation is
