a cylinder has radius labeled 2.4 meters and height labeled 6.5 meters

43 square meters

113 square meters

134 square meters

341 square meters

Answers

Answer 1

Answer:

[tex]≈134 \: {cm}^{2} [/tex]

Step-by-step explanation:

Given:

r (radius) = 2,4 m

h (height) = 6,5 m

π = 3.14

Find: A (surface area) - ?

[tex]a(surface) = 2\pi {r}^{2} + 2\pi \times r \times h[/tex]

[tex]a(surface) = 2 \times 3.14 \times ({2.4})^{2} + 2 \times 3.14 \times 2.4 \times 6.5 ≈134 \: {cm}^{2} [/tex]

You could draw a rectangular prism with the sides 10, 2 and 3. The volume of the given one is 60 because 5 times 6 times 2 is 60. 10 times 2 times 3 also equals 60 so they would have the same volume.

4. Do you think it would be useful to be able to predict future population? Why?

5. Identify factors that influence population growth?

6. Identify possible consequences of population growth.

Answers

4. Yes, it would be useful to be able to predict future population for a variety of reasons. Governments, businesses, and organizations can use population predictions to plan for future needs such as housing, healthcare, education, and transportation. Population predictions can also inform policy decisions related to immigration, national security, and environmental management.

5. Factors that influence population growth include:Birth rate: The number of births per 1,000 individuals in a population over a specified period of time.Death rate: The number of deaths per 1,000 individuals in a population over a specified period of time.Migration: The movement of people into or out of a population.Age structure: The proportion of individuals in different age groups within a population.Fertility rate: The average number of children born per woman in a population.Life expectancy: The average number of years a person is expected to live in a population.6. Possible consequences of population growth include:Strain on resources: As the population grows, there is increased demand for resources such as food, water, and energy, which can lead to scarcity and competition.Environmental degradation: Increased population can lead to deforestation, pollution, and habitat destruction, which can have negative effects on the environment and the species that inhabit it.Urbanization: As more people move to cities, there can be issues with overcrowding, traffic congestion, and housing shortages.Economic impacts: Population growth can have both positive and negative economic impacts, such as increased consumer demand and higher unemployment rates. Social and political impacts: Population growth can lead to social and political tensions, such as conflicts over resources and migration policies.
4. Yes, because knowing what the population will be we can find resources to expand or maybe even decrease the population.

5. Reproducing.

6. The world will be over populated. We will probably not have enough resources.

The median decreases to 77°.
The median decreases to 65.2°.
The median stays at 82°.
The median stays at 79.5°.

Answers

Answer: The median decreases to 77°.

A makeup artist purchased some lipsticks and wants to wrap them individually with gift wrap. Each lipstick has a radius of 0.4 inch and a height of 2.2 inches. How many total square inches of gift wrap will the makeup artist need to wrap 3 lipsticks? Leave the answer in terms of π.

2.08π square inches

6.24π square inches

8.32π square inches

19.59π square inches

Answers

Answer:

[tex]6.24\pi \: {in}^{2} [/tex]

Step-by-step explanation:

Given:

r (radius) = 0,4 in

h (height) = 2,2 in

n (the number of lipsticks) = 3

Find: A (total surface area) - ?

First, we have to find how much gift wrap will the makeup artist need to wrap one lipstick:

[tex]a(surface1) = 2\pi {r}^{2} + 2\pi \times r \times h[/tex]

[tex]a(surface1) = 2\pi \times ({0.4})^{2} + 2\pi \times 0.4 \times 2.2 = \frac{52\pi}{25} [/tex]

Now, let's multiply this number by the quantity of lipsticks the makeup artist has to wrap:

[tex]a(total) = \frac{52\pi}{25} \times 3 = \frac{156\pi}{25} = 6.24\pi \: {in}^{2} [/tex]

Answer:
6.24t in?
Step-by-step explanation:
Given:
r (radius) = 0,4 in
h (height) = 2,2 in
n (the number of lipsticks) = 3
Find: A (total surface area) - ?
First, we have to find how much gift wrap will the makeup artist need to wrap one lipstick:
a(surfacel) = 27/2 + 27 xrx h
a(surface1) = 27 × (0.4)? + 27 x 0.4 x 2.2 = 525
Now, let's multiply this number by the quantity of lipsticks the makeup artist has to wrap:
a(total) = 55 × 3=46 = 6.24rin? R is pi

-2.25 + 0.4x = -2.8

Solve as a simplified mixed number and as a decimal

Answers

Answer:

-1 3/8 and  -1.375

Step-by-step explanation:

To solve for x in the equation -2.25 + 0.4x = -2.8, we can start by isolating the variable term (0.4x) on one side of the equation:

-2.25 + 0.4x = -2.8

0.4x = -2.8 + 2.25

0.4x = -0.55

Next, we can divide both sides by 0.4 to solve for x:

x = -0.55 / 0.4

x = -1.375

As a mixed number, -1.375 can be written as:

-1 3/8

As a decimal, -1.375 is already in decimal form.

-1 3/8 and -1.375 is the answers

Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.

scatter plot titled students' data, with points plotted at 1 comma 80, 2 comma 70, 2 comma 80, 2 comma 90, 3 comma 80, 3 comma 100, 4 comma 90, and 4 comma 98, and a line of fit drawn passing through the points 0 comma 70 and 1 comma 75

Find the y-intercept of the line of fit and explain its meaning in the context of the data.

80; a student who studies for 0 hours is predicted to earn 80% on the test
70; a student who studies for 0 hours is predicted to earn 70% on the test
10; for each additional hour a student studies, their grade is predicted to increase by 10% on the test
5; for each additional hour a student studies, their grade is predicted to increase by 5% on the test

Answers

Answer:

Step-by-step explanation:

The y-intercept of the line of fit is 70, which means that a student who does not study at all (0 hours) is predicted to earn a grade of 70%. In other words, the line of fit starts at the point (0,70), indicating that even if a student does not study at all, they can still earn a grade of 70% on the test. However, it should be noted that this prediction may not always hold true for all students and situations. The y-intercept provides a useful reference point for interpreting the rest of the data, and helps to establish a baseline for the relationship between study time and test grades.
