A laboratory culture contains 150 bacteria. After twenty minutes, the culture contains 300 bacteria. After one hour, the culture contains 1200 bacteria. Make a conjecture about the rate at which the bacteria increases

Answers

Answer 1
the answer is C..!! 
see.. at t=0 the culture had 150 bacteria.. 
at t=20 the culture had 300 bacteria. 
at t=60 the culture had 1200. 
so if u go by the second option... at t=40 the bacteria would be 600..!! and it makes sense because it fits the sequence...!! 
i am just telling you the logic..!! if u have to formally solve it.. use the concept of sequences and series... :)
Answer 2
Final answer:

The bacteria in your culture appear to be experiencing exponential growth, doubling in population size every 20 minutes. This is common in organisms that reproduce by binary fission like bacteria, but the growth rate can be influenced by various environmental factors.

Explanation:

Based on your data, the number of bacteria in your culture seems to double every 20 minutes. This type of growth pattern is known as exponential growth, which is common in prokaryotes and other organisms that reproduce by binary fission.

For example, if you were to start with 1000 bacteria in a nutrient-rich environment, after one hour (or three 20-minute intervals), each bacterial cell would've divided several times, increasing the total population size from 1000 to 8000. This is based on the principle that in exponential growth, the number of new organisms added to the population in each round of division (or generation) increases as the population size increases. This results in a 'J-shaped' growth curve when plotted over time, illustrating the increasing rate of population growth.

However, please note that in reality, bacterial growth is influenced by several factors including nutrient availability and environmental conditions and the growth rate may not remain constant over time. For a more accurate analysis, you could take readings at more frequent intervals and plot a graph of population size versus time to observe the growth pattern.

one serving of soybeans contains 10 grams of protein, which is 4 times the amount in one serving of kale. write and solve an equation to find the amount of protein in one serving of kael

Answers

One serving of kale contains 2.5 grams of protein. This is determined by the equation 4x = 10, where x represents the protein content in one serving of kale, and solving for x.

Let x represent the amount of protein in one serving of kale. The given information states that one serving of soybeans contains 10 grams of protein, which is 4 times the amount in one serving of kale.

So, the equation is:

4x = 10

Now, solve for x:

x = [tex]\frac{10}{4}[/tex]

x = 2.5

Therefore, one serving of kale contains 2.5 grams of protein.

The complete question is:

One serving of soybeans contains 10 grams of protein, which is 4 times the amount in one serving of kale. Write and solve an equation to find the amount of protein x in one serving of kale.

Ann travels from town A to town B in 3 hours. She then takes another hour to travel from town B to town C. The distance between town A and town B is 100 miles. The distance between town B and town C is 40 miles. What is Ann's average speed for the whole journey?

Answers

Ann's average speed for the entire journey from town A to town C is calculated by dividing the total distance traveled, which is 140 miles, by the total time taken, which is 4 hours, resulting in an average speed of 35 mph.

Calculating Average Speed for the Whole Journey

To calculate Ann's average speed for the entire trip from town A to town C, we first need to find the total distance traveled and the total time taken. Ann travels 100 miles from A to B, then another 40 miles from B to C, totaling 140 miles for the distance. The time taken for the first leg of the trip is 3 hours, and for the second leg, it's 1 hour, totaling 4 hours for the entire journey.

Now, we calculate the average speed using the formula:

Average Speed = Total Distance / Total Time

Average Speed = 140 miles / 4 hours = 35 miles per hour (mph).

This is the average speed for the whole trip from town A to town C.

A plumber has a 50 foot piece of PVC pipe. how many 9/5 foot pieces can be cut from the 50 foot piece?

Answers

Answer:

[tex]27\frac{7}{9}\approx 27[/tex] pipes.

Step-by-step explanation:

We have been given that a plumber has a 50 foot piece of PVC pipe. We are asked to find the number of 9/5 foot pieces of pipes that could be cut from the 50 foot piece.

To find the number of 9/5 foot pieces of pipes, we will divide total length of PVC pipe by 9/5 foot.

[tex]\text{Number of 9/5 foot pieces of pipes}=50\div \frac{9}{5}[/tex]

Convert to multiplication problem:

[tex]\text{Number of 9/5 foot pieces of pipes}=50\times \frac{5}{9}[/tex]

[tex]\text{Number of 9/5 foot pieces of pipes}=\frac{250}{9}[/tex]

[tex]\text{Number of 9/5 foot pieces of pipes}=27\frac{7}{9}[/tex]

[tex]\text{Number of 9/5 foot pieces of pipes}\approx 27[/tex]

Therefore, the plumber can make [tex]27\frac{7}{9}\approx 27[/tex] pipes.

28 of the  [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece.

Given the following data;

Total length of PVC pipe = 50 footRequired length of PVC pipe = [tex]\frac{9}{5}[/tex] foot

In this exercise, you're required how many  [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece. To do this we would divide the 50 foot piece of PVC pipe by [tex]\frac{9}{5}[/tex].

[tex]50[/tex] ÷ [tex]\frac{9}{5}[/tex] = [tex]\frac{50}{\frac{9}{5}}[/tex]

Simplifying the equation, we have;

[tex]\frac{50 \;X \;5}{9}[/tex]

[tex]\frac{250}{9}[/tex]

Number of pipes = 27.77 ≈ 28 pipes.

Therefore, 28 of the  [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece.

On a miniature golf course the distance from the tee to the first hole is 96 inches the distance to the second hole is 3 yards on the third tee the holes is 12 feet away which of the tees is farthest from the whole

Answers

Final answer:

After converting all distances to inches, the third tee is the farthest from the hole at 144 inches.

Explanation:

To find out which tee is farthest from the hole, we need to convert all distances to the same unit. For this problem, we will use inches, since the first distance is already given in inches.

The first hole is 96 inches away.The second hole is 3 yards away. There are 36 inches in a yard, so this is 3 yards × 36 inches/yard = 108 inches.The third hole is 12 feet away. There are 12 inches in a foot, so this is 12 feet × 12 inches/foot = 144 inches.

Comparing the distances, the third hole is the farthest away at 144 inches.
