The area of a 2D form is the amount of space within its perimeter. The area of the bottom of the box is 64 square inches.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.
Given the radius of the base of the plastic bottle is 2 inches, and there are four bottles arranged as shown below, therefore, the area of the bottom of the box is,
[tex]\rm \text{Area of the bottom of the box} = 8 \times 8 = 64\ in^2[/tex]

Use for questions 21-24: Out of 50 students, 24 are taking art and 30 are taking music. Sixteen of the
students are taking both art and music. If two different students from this group are chosen at
random, find each probability.
21. Both students take art
22. Both students take both art and music.
23. Both students take music, but not art.
24. Neither students takes music.
Probability of each case given in the problem will be 0.3327, 0.1033, 0.0922, 0.3367 respectively.
What does probabilty of occurance of an event signifies?The probability of an occurrence is an indicator of its likelihood. It is most frequently described as a number between 0 and 1, where 0 indicates an impossibility and 1 indicates assurance.
If an event has a higher probability, it is more likely to happen. One can use various mathematical methods or, depending on the situation, divide the number of favourable possibilities by the total number of potential outcomes to calculate the likelihood of an event.
Now for given cases in the problem,
21. Chances that both pupils will enrol in art: divided by the total number of ways there are to select two students from the full group of 50 students, the number of ways to select two students from the 24 art students is equal to= [tex]^{24}C_2 / ^{50}C_2=(\frac{24!}{22!.2!})/(\frac{50!}{48!.2!} )= \frac{24*23}{2} /\frac{50*49}{2} =0.3327[/tex]
22. Chance that both pupils would study music and art: the number of options there are to select two students from the 16 students who are studying both art and music divided by the total number of methods there are to select two students from the 50 students.= [tex]^{16}C_2 / ^{50}C_2=(\frac{16!}{14!.2!})/(\frac{50!}{48!.2!} )=\frac{16*15}{2} /\frac{50*49}{2} =0.1033[/tex]
23. Probability that both students take music but not art is calculated by dividing the total number of possibilities there are to select two students from the 50 students by the number of students in the group of 14 who only take music= [tex]^{14}C_2 / ^{50}C_2=(\frac{14!}{12!.2!})/(\frac{50!}{48!.2!} )= \frac{14*13}{2} /\frac{50*49}{2} =0.0922[/tex]
24. The likelihood that neither student studies music is determined by the number of ways there are to select two students from the 26 students who do not study music divided by the total number of ways there are to select two students from the complete group of 50 students. = [tex]^{26}C_2 / ^{50}C_2= (\frac{26!}{24!.2!})/(\frac{50!}{48!.2!})=\frac{26*25}{2} /\frac{50*49}{2} = 0.3367[/tex]

Bobby has a party while his parents are away for the weekend. Bobby estimated that if his 9 friends hep him to clean the house, they will finish in time if they start 8 hours before his parents return. But after only two hours of cleaning, Bobby's parents call and say they are just two hours from home. How many more friends does Bobby need to call to help finish cleaning in time.
Using an inverse rule of three, it is found that Bobby needs to call 18 more people.
What will be the number of friends?This question is solved by proportions, applying a rule of three.The number of people working and the time needed to complete the work are inversely proportional, as more people means less time, thus, instead of cross multiplication, we multiply the lines, which is an inverse rule of three.When Bobby's parents call, with 9 people, they will need 6 hours to finish the job. How many people are needed to finish the job in 2 hours?
The rule of three is:
9 people - 6 hours
x people - 2 hours.
Multiplying by line:
2x = 6 x 9
x = 3 x 9
x = 27
Already has 9 people, in total needs 97, so he needs to call 27 - 9 = 18 more people.

Find the two square roots of 121.
Answer:
11 and -11
Step-by-step explanation:
This problem can really only be solved either by way of a calculator or simple memorization. In this case, the product (121) is a perfect square root, meaning it has a whole number answer. One square root of 121 is 11. The second square root of 121 is -11.
[tex]\sqrt{121} = 11[/tex]
[tex]\sqrt{121} = -11[/tex]
You can check your work by squaring your answer and seeing whether it equals the product. Remember, a negative number times another negative number results in a positive answer.
[tex]11^{2} = 121[/tex]
[tex]-11^{2} = 121[/tex]
The two square roots of the number 121 are 11 and -11.
The square root of a number is a value that, when multiplied by itself, gives the original number.
In the case of 121, the square root represents the number that, when multiplied by itself, equals 121.
The two square roots of 121 are 11 and -11 because both 11 and -11, when squared, result in 121.
When we calculate 11 × 11, we get 121.
So, 11 is one of the square roots of 121.
Similarly, when we calculate (-11) × (-11), we also get 121. So, -11 is also a square root of 121.
Therefore, the two square roots of 121 are 11 and -11.

The height of an object launched into the air can be modeled by the graph shown.
Enter your answer as a number, like this: 42
The maximum height reached by the object is 12.5 feet.
Describe Parabola?The vertex of a parabola is the point where the curve changes direction, and is located at the minimum or maximum point of the quadratic equation. If the coefficient of the x² term is positive, the parabola opens upwards and the vertex represents a minimum value. If the coefficient is negative, the parabola opens downwards and the vertex represents a maximum value.
To find the maximum height reached by the object, we need to find the vertex of the parabola.
The x-coordinate of the vertex can be found using the formula x = -b/2a, where a is the coefficient of the x² term, and b is the coefficient of the x term in the quadratic equation that represents the parabola.
In this case, the equation is of the form y = ax² + bx + c, where y is the height and x is the time. Using the given coordinates, we can set up a system of equations to solve for a, b, and c:
0 = a(1)² + b(1) + c
16 = a(5)² + b(5) + c
0 = a(9)² + b(9) + c
Simplifying each equation, we get:
a + b + c = 0
25a + 5b + c = 16
81a + 9b + c = 0
Solving for c in the first equation, we get c = -a - b. Substituting this into the other two equations, we get:
25a + 5b - a - b = 16
81a + 9b - a - b = 0
Simplifying these equations, we get:
24a + 4b = 16
80a + 8b = 0
Solving for b in the second equation, we get b = -10a. Substituting this into the first equation, we get:
24a + 4(-10a) = 16
4a = 2
a = 1/2
Substituting this value of a into the equation b = -10a, we get b = -5. Finally, substituting a, b, and c = -a - b into the equation for the x-coordinate of the vertex, we get:
x = -b/2a = 5
So the maximum height is achieved at time x = 5, which corresponds to a height of:
y = ax² + bx + c = (1/2)(5)² - 5(5) = -12.5
However, we are looking for the maximum height, so we take the absolute value of this result, which gives:
|y| = 12.5
Therefore, the maximum height reached by the object is 12.5 feet.

6 Three of the ten people in the Latin club are chosen at random to represent the club at a tournament. What is the probability that Joseph, Heidi, and Katy are chosen?
The probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Total ways of choosing 3 out of 10 = C(10, 3) = 120
Total outcomes = 120
Total favorable outcomes = 3(Joseph, Heidi, and Katy)
Probability = 3/120 = 1/40
Thus, the probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.
