a culture started with 2000 bacteria after 6 hours it grew to 2400 bacteria how many bacteria will grow after 16 hours
Answers
Answer 1
Answer:
First, you have to find the unit rate by dividing 2000/6=333.33 but round it up to 333 So the unit rate is 333 bacteria per hour Then, you have to multiply 333x16= 5,328 bacteria after 16 hours
The answer is that in 16 hours, there will be 5,328 bacteria
What is the approximate volume of the cylinder? height = 52.2 cm; diameter = 20 cm
A. 1640 cm3
B. 3300 cm3
C. 16,400 cm3
D. 65,600 cm3
Answers
h = 52.2 diameter = 20 cm radius = 10 cm Cylinder volume = π • r² • height Cylinder volume = PI * 100*52.2
Cylinder volume = 16,399 answer is C

What's 1.2 liters of water in -20 milliliters of water
Answers
I don't really know what you are asking so I am just going to give some answers to varies questions to try to answer what you need.
1 liter equals 1000 milliliters
That means that 1.2 liters of water is equal to 1200 milliliters of water 1.2 Lx1000 mL/L=1200 L and 20 milliliters of water equals 0.020 L of water 20mLx(1 L/1000 mL)=0.020 L
Hope this helps you and you can leave a comment if you have any further questions or if my answer did not answer your question.
Simplify. [6.6 ÷ (–5 + 3)] • (–1)
Answers
Hi there, we use PEMDAS to solve this problem, PEMDAS is parenthesis, Exponents, Multiply, Divide, Add, and Subtract. In this case, we have [6.6÷(-5+3)]*(-1), 6.6/-5+3(-1)=6.6/-2(-1)=(-3.3)(-1)=3.3. So, your answer is 3.3
Is 1/3 equivalent to 1/3x explain your reasoning
Answers
So the question is does 1/3 = 1/3x
To solve this, basically we just have to solve for x to see if it gives us a true statement. Since x is a variable, it could represent any number... so we have to determine whether the statement could be true with any other numbers as well...
1/3 = 1/3x divide each side by 1/3 (multiply by the reciprocal) 1/3 x 3/1 = x 1 = x
So when x = 1 then the statement 1/3 = 1/3x is true. If we put any other number as x the statement would be false... for example if you let x = 2, then 1/3 x 2/1 = 2/3... that does not equal 1/3 so it is a false statement and they are not equivalent when x = 2.
Your answer is, YES 1/3 is equivalent to 1/3x but ONLY when x = 1
