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]

Which number sentence is true?
Answer:
D should be the correct answer
Step-by-step explanation:
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
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]
A restaurant chef wants to install a new floor in her kitchen. The kitchen measures 8 yards wide and 12 yards long, and the flooring costs $2.00 per square yard. How much will the chef's new floor cost.
Answer: $192
Step-by-step explanation:
First find the area of the kitchen using the formula b*h=A: 8*12=96
Then multiple this by 2 because it is $2 every square yard: 96*2=192
$192
A McDonald's cheeseburger cost $0.79 in 1999. Today that cheeseburger costs $1.00. What is the percent change?
A) 26.58% Increase
B) 21% Decrease
C) 21% Increase
D) 26.58% Decrease
Answer:
The percentage change from 0.79 to 1.00 is 26.58 % increase
Step-by-step explanation:
((1.00 - 0.79) / 0.79) * 100 = 26.58%
Answer:
26.58% Increase
Step-by-step explanation:
Using the formula %Increase=100×final-initial/initial
%Increase=100×1-0.79/0.79=26.58%
What number would you subtract from both sides of the equation to solve for c?
c + 7 = -14
(Only write the number that you would subtract. Do no write the equation.)
To solve for c in the equation c + 7 = -14, you would subtract 7 from both sides of the equation.

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
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.

Answer:
H. is the correct answer.
Step-by-step explanation:
You find range by subtracting the lowest amount from your data by the highest amount. The highest number in Ms. Gambino's class is 12, and the lowest is 5.
[tex]12-5=7[/tex] This is the range of Ms. Gambino's class
The highest number in Mr. Joe's class is 10 and the lowest is 5
[tex]10-5=5\\[/tex] This is the range of Mr. Joe's class.
Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.
-2.25 + 0.4x = -2.8
Solve as a simplified mixed number and as a decimal
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.

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.
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.Vanessa sells bracelets at a craft fair. She spends a total of $42.00 on supplies to make the bracelets. She sells each bracelet for $3.00. Vanessa wants to earn a profit of at least $150.00 at the craft fair. Which inequality can be used to determine the number of bracelets, x, she needs to sell to meet her goal.
you need to do 150$ plus 42$ so she can make up the money she lost then, you need to divide 192$ by 3$ and then you would get 64. hope this helps

The average high temperatures in degrees for a city are listed.
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 50° is added to the data, how does the median change?
The median decreases to 77°.
The median decreases to 65.2°.
The median stays at 82°.
The median stays at 79.5°.
Answer: The median decreases to 77°.
Step-by-step explanation:
1. First step is to order all the numbers from least to greatest.
50, 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
2. Second step is to find the middle number
50, 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
3. The middle number is the answer so in this case the median is now 77 which means the answer is the first choice.
Answer:
77
