Step-by-step explanation:

GivenInitial population at 8:00 AM3000000Growth rate = 10% = 1.1 times per 20 minSolution

1. Table

Note. I am not sure what are the last 3 rows. Just added next 3 terms.

8:00  ≡  G(0)   ≡   3000000              ≡  30000008:20  ≡  G(1)    ≡   3000000 *1.1        ≡  33000008:40  ≡  G(2)   ≡   3000000 *1.1^2    ≡  36300009:00  ≡  G(3)   ≡   3000000 *1.1^3    ≡  39930009:20  ≡  G(4)   ≡   3000000 *1.1^4    ≡  4392300

2. Population at 10:00

Time passed since 8:00 is 2 hours = 2*3*20 min = 6* 20 minPopulation = 3000000*1.1^6 = 5314683

3. Function to reflect the population growth

G(x) = 3000000*1.1^xG(x) - is dependent variable, population of bacteriax - is independent variable, time increment of 20 min

4. Population after 5 hours

5 hours = 5*3*20 min = 15*20 minG(15) = 3000000*1.1^15 ≈ 12531745

What is the difference in the cost of doughnuts at the two shops?

Answers

Given parameters:

Cost of doughnut at one shop = £1.40

Unknown

Difference in the cost of doughnuts at the two shops = ?

To find the difference in the cost of doughnuts at the two shops, we must know the cost of doughnut at the second shop;

  Given that the cost of doughnut at the other shop is 20% more;

       = 1.20 x £1.4

       = £1.68

The difference in the cost of doughnuts  = £1.68 - £1.40 = £0.28

So the answer is £0.28

if y varies directly with X and Y=24 when x=6, find x when y = 32​

Answers

Answer:

8

Step-by-step explanation:

if y varies with x, then they are directly proportional, so their ratio is constant (ie x divided by y is allways the same)

when x = 6, y = 24:

y / x = 4

when y = 32:

32 / x = 4

so x = 32 / 4 = 8

x=6
y=24

To get to 24, you multiply x by 4

x= ____
y=32
To get x, start with y and do the reverse, dividing by 4. 32/4=8

So, x=8

Andre says that any real number can go in either of the boxes and A will be a
polynomial. Is he correct? Explain your reasoning.

Answers

Answer:

Andy is incorrect

Step-by-step explanation:

[See attachment for complete question]

Andy is incorrect because of the following.

Filling the empty boxes with any real numbers does not guarantee that the expression will be a polynomial.

For instance, if the expression is completed as thus:

(5x⁴ + 4x³)(4x^(2.7981) - 6) = A

This expression is not a polynomial because all powers of x must be non negative and it must be an integer.

So, Andy's statement is incorrect

A phone company charges a base fee of $12 per month plus an additional charge per minute.the monthly phone cost c can be represented by this equation: c=12+a •m, where a is the additional charge per minute, and m is the number of minutes used.
What equation can be used to find the number of minutes a customer used I we know a and c

Answers

Answer:

Hi there!

Your answer is

(C-12)/A = M

Step-by-step explanation

c=12+a * m

SOLVE FOR M!

C=12+AM

-12

C-12+AM

Divide out A to isolate M

(C-12)/A = M

The equation that can be used to find the number of minutes[m] a customer used is -   m = (c - 12)/a

What is equation rearrangement?

Equation rearrangement is a process of arranging the equation parameters in terms of a specific parameter.

Given is a phone company that charges a base fee of $12 per month plus an additional charge per minute. The monthly phone charge cost [c] can be represented by the equation: c = 12 + a x m, where [a] is the additional charge per minute, and [m] is the number of minutes used.

The given equation is -

c = 12 + a x m

Since, we know the values of [a] and [c], we can solve for [m] as follows -

c = 12 + a x m

c - 12 = a x m

m = (c - 12)/a

Therefore, the equation that can be used to find the number of minutes[m] a customer used is -

m = (c - 12)/a

9) It takes 7 minutes for Isabella to walk
around the gym track twice. At this
rate, how many times can she walk
around the track in a half hour?

Answers

Answer:

8 4/7

Step-by-step explanation:

Use a proportion.

Let the unknown number of laps for 30 minutes be x.

7 minutes is to 2 laps as 30 minutes is to x laps

7/2 = 30/x

Cross multiply.

7x = 2 * 30

7x = 60

x = 60/7

x = 8 4/7

Answer: 8 4/7

Isabella walks twice around the gym track in 7 minutes. She can do 60/7 laps of the track in a half hour if she continues moving at this pace.

What is the meaning of the term “laps”?

Running a lap is equivalent to making a full circle of a track during a race or while exercising while walking. the front portion of the human body, when seated, from the waist to the knees. the area of clothing that, while a person is sitting, covers the front of their body from the waist to their knees. a location, setting, or circumstance that promotes rest or nurturing: the lap of luxury.

Laps are being done to get a good workout. For beginners, 20–30 laps in 30 minutes is frequently an effective and reachable target. If you're more advanced, try to do 40 to 50 laps in the same amount of time, and aim for 60 or more.

Let x equal the undetermined number of laps for 30 minutes.

7 minutes equals 2 laps, while 30 minutes equals x laps.

[tex]\frac{7}{2} = \frac{30}{x}[/tex]

Cross multiply.

[tex]7x = 2 \times 30\\7x = 60\\x = \frac{60}{7}\\[/tex]

Therefore, Isabella can do 60/7 laps of the track in a half hour if she continues moving at this pace.

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood = [tex] \frac{11}{100}*145 = \frac{1,595}{100} = 15.95 [/tex]

Type B blood donors ≈ 16

b. No. of blood donors without blood type O = [tex] \frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75 [/tex]

There are more than 7,000 languages spoken in the world today, and, on average, one of them disappears every ten days. What does that mean for the future of language diversity? What about the future of cultural diversity

Answers

Answer:

One language disappears every ten day. Each language has history and culture that vanishes. This will affect the future of language and cultural diversity because people aren’t trying to save theses languages and culture. Imagine if the English language disappeared. Plenty of English speaking countries’ cultural would also disappear. Plus, lots of these languages know one knows about. The future of language diversity would be bland, for only big languages would exist. Therefore, the disappearance of languages will affect language because people don’t try to save culture, and there’d be no language diversity in the future.

The disappearance of languages at such a rapid pace has significant implications for both language diversity and cultural diversity.

Language diversity is essential as it reflects the richness and complexity of human communication and expression. Each language carries unique ways of perceiving and understanding the world, and its loss means losing a vast amount of cultural and intellectual knowledge.

When languages disappear, the world loses diverse perspectives, traditional knowledge systems, folklore, literature, and linguistic diversity itself.

Furthermore, language is deeply intertwined with cultural diversity. Language shapes and is shaped by culture, and it serves as a vehicle for transmitting cultural practices, values, beliefs, and traditions across generations. When a language vanishes, it often signifies a loss of cultural identity and can lead to the erosion of cultural practices and knowledge associated with that language. The extinction of a language can disrupt intergenerational transmission of cultural heritage, affecting not only linguistic diversity but also cultural diversity.

The consequences of language extinction extend beyond the loss of knowledge and cultural heritage. Language is an integral part of personal and collective identity. When a language dies, it can cause a sense of disconnection, loss, and alienation for the speakers and their communities. Language loss can also exacerbate social and economic inequalities, as marginalized communities often face language-based discrimination and exclusion.

To preserve language diversity and cultural diversity, concerted efforts are needed. Governments, communities, linguists, educators, and language enthusiasts can play a crucial role in documenting endangered languages, revitalizing them through language revitalization programs, promoting bilingual education, and creating platforms for language preservation and intercultural exchange. Recognizing the value of linguistic and cultural diversity is essential for fostering understanding, tolerance, and respect among different communities.

Overall, the future of language diversity and cultural diversity depends on our collective commitment to preserving, revitalizing, and celebrating the vast array of languages and cultures that enrich our world.
