Harriet is cultivating a strain of bacteria in a petri dish, she has 10^3 bacteria in the dish. The bacteria divided every two hours such that the number of bacteria has doubled by the end of every second hour. How many bacteria will Harriet have in the dish at the end of 6 hours?

Answers

Answer 1

Answer:

4000

Step-by-step explanation:

A=P(2)^(t/d)

A=future amount

P=starting amount

t=time elapsed

h=doubling time

given

P=10^3

t=6

d=2

A=10^3(2)^(6/2)

A=10^3(2)^2

A=10^3(4)

A=4*10^3

A=4000

4000 bacteria

-5c-15=-35 all I really want is what -5c equals to and what c equals too

Answers

Answer: c=4

Step-by-step explanation:

Add 15 on each side to get rid of the -15 on the left side.That results in getting: -5c=-20. That would be the answer for what -5c equals.To find what c equals, we must divide by -5 on each side. Thus, c=4.If we plug it in, it works, so we know the answer is correct.

Answers

Answer:

-4

Step-by-step explanation:

2 more than the product of 3 and a number is -10 can be written as 3x+2=-10.

we can take this equation and solve it, first subtracting 2 from both sides to get 3x=-12.

now we divide both sides by 3 to get x=-4, so the answer is -4.

2x = 106     <-- Divide by 2
