Suppose a population has a doubling time of 25 years. By what factor will it grow in 25 years? 50 years? In 100 years?

Answers

Answer 1
Final answer:

A population with a doubling time of 25 years will grow by a factor of 2 in 25 years, by a factor of 4 in 50 years, and by a factor of 16 in 100 years, based on the exponential growth rule.

Explanation:

If a population has a doubling time of 25 years, by what factor will it grow in various timeframes? Let's calculate this using the rule of exponential growth.

In 25 years, the factor by which the population will grow is 2, because the definition of doubling time implies that the population doubles every 25 years.

In 50 years, which is two doubling periods, the population will grow by a factor of 2^2 (2 raised to the power of 2), which is 4.

In 100 years, which is four doubling periods, the population growth factor will be 2^4 (2 raised to the power of 4), which equals 16.

Thus:

After 25 years, growth factor = 2After 50 years, growth factor = 4After 100 years, growth factor = 16

Omar buys candy that costs $8 per pound. He will spend at least $40 on candy. What are the possible numbers of pounds he will buy?
Use p for the number of pounds Omar will buy.
Write your answer as an inequality solved for p.

HELP ASAP​

Answers

Final answer:

Omar will buy at least 5 pounds of candy. To find this, divide his minimum spending ($40) by the cost per pound of candy ($8). The inequality solved for p is p \geq 5, meaning Omar can buy 5 or more pounds of candy.

Explanation:

To find out the possible number of pounds of candy Omar will buy, we can set up an inequality using the given information. We know the cost per pound of candy is $8, and Omar is going to spend at least $40 on candy. Therefore, the inequality representing the situation can be written as:

8  imes p \\(cost per pound \\ times number of pounds)\\ \geq 40 (Omar's minimum spending)

To solve for p, the number of pounds, we divide both sides of the inequality by 8:

p \geq \frac{40}{8} \Rightarrow p \geq 5

So, Omar will buy at least 5 pounds of candy. This means that the possible numbers of pounds he may buy are 5 or more.

what is the sum of 2/10 + 6/100

Answers

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50

The sum of 2/10 and 6/100 is 13/50.

To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.

The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.

Now, we'll rewrite both fractions with the common denominator of 100:

2/10 = (2/10) * (10/10) = 20/100

6/100 = 6/100

Now that both fractions have the same denominator, we can add them together:

20/100 + 6/100 = (20 + 6)/100 = 26/100

Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:

(26 ÷ 2) / (100 ÷ 2) = 13/50

B. 20x^2+36x-16

C. 20x^2-4x-16

D. 9x^2-16

Please help, thank you

Answers

Note: As you may have unintentionally missed to add the diagram. After a little research, I was able to find the diagram. I have attached the diagram, based on which I am solving which anyways would clear your concepts.

Answer:

The area of the storage facility is [tex]20x^2-4x-16\:\:square\:feet[/tex].

Step-by-step explanation:

From the attached diagram, it is clear that

The length of the rectangle  [tex]=5x + 4[/tex]The width of the rectangle [tex]= 4x - 4[/tex]

The area of the storage facility in square feet can be calculated by finding the area of rectangle.

So, using the area of rectangle formula

                [tex]A = lw[/tex]

                    [tex]=\:\left(5x+4\right)\left(4x-4\right)[/tex]

[tex]\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

[tex]a=5x,\:b=4,\:c=4x,\:d=-4[/tex]

                        [tex]=5x\cdot \:4x+5x\left(-4\right)+4\cdot \:4x+4\left(-4\right)[/tex]

                        [tex]=5\cdot \:4xx-5\cdot \:4x+4\cdot \:4x-4\cdot \:4[/tex]

                        [tex]=20x^2-4x-16[/tex]  

Therefore, the area of the storage facility is [tex]20x^2-4x-16\:\:square\:feet[/tex].

Final answer:

To find the area of the storage facility, calculate the area of each shape and add them together. The correct expression is 36x^2+24x.

Explanation:

To find the area of the storage facility, we need to find the area of each individual shape and add them together. Looking at the diagram, we can see that the storage facility is composed of two rectangles and one square. Let's calculate the area of each shape:

Area of first rectangle = length x width = 4x(4x+4) = 16x^2+16x

Area of second rectangle = length x width = 4x(4x+2) = 16x^2+8x

Area of square = side x side = (2x)^2 = 4x^2

To find the total area, we add the areas of the three shapes:

Total area = (16x^2+16x) + (16x^2+8x) + 4x^2 = 36x^2+24x

Therefore, the correct expression that represents the area of the storage facility is 36x^2+24x, which is option B.

There are 11 pairs of twins at a school with 2750 students.

What is division?

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

Given identical  twins happen once in 250 births,

total number of students in school = 2,750

to find the pair of twins divide the total number of students by 250

= 2750/250 = 11

Understand the different types of life insurances.
term life
whole life

Answers

Term life : Term life insurance provides coverage for a certain time period. It’s often called “pure life insurance” because it’s designed to only protect your dependents in case you die prematurely. If you have a term policy and die within the term, your beneficiaries receive the payout. The policy has no other value.


Whole life : like all permanent life insurances policies, whole life provides lifelong coverage and includes an investment component known as the policies cash value. The cash value grows slowly, tax-differed, meaning you won’t pay taxes on its gains while they are accumulating. You can borrow money against the account or surrender the policy for the cash. But if you don’t repay policy loans with interest, you’ll reduce your death benefit, and if you surrender the policy, you’ll no longer have coverage.

Write a statistical question that might have been asked to gather the data. Then explain why it is statistical.

Answers

Answer:

The question is: How much time do people spend in the water park?

It is a statistical because the answer comes from a sample instead of from the entire population.

Explanation:

Rewrite the table

Hours Spent at Water Park

     Hours     Tally

       4              4

       5              5

       6              3

       7              4

These data could be the results of a survey whose target was to detemine how many hours people spent at a water park.

The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.

And the question most likely was made at the exit of a water park, when the people were leaving the park.

Thus, the statistical question could be How much time do people spend in the water park?

It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people. All the people who go to the water park is the population about whom you want to determine how much time they spend in the water park, but,since it is impossible to survey all the people, you need to survey a sample.

The resulting values from a sample are named statistical. The values for an entire population are named parameters. A statistical permits to draw conclusions for populations using just one or more samples, which should be random samples.

Answer:

Step-by-step explanation:

“How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric.

The difference of 2x and 5 is greater than -3 and less than or equal to 11

Answers

The solution to the inequality is 1 < x ≤ 8.

The given inequality can be split into two components:

The difference of 2x and 5 is greater than -3: This can be written as:

2x - 5 > -3

To solve for x, we first add 5 to both sides of the inequality:

2x > 2

Then, we divide both sides by 2:

x > 1

This indicates that the values of x which satisfy this part of the inequality are greater than 1.

The difference of 2x and 5 is less than or equal to 11: This can be written as:

2x - 5 ≤ 11

Adding 5 to both sides:

2x ≤ 16

Dividing both sides by 2:

x ≤ 8

Therefore, the common range that satisfies both parts is 1 < x ≤ 8.
