Answers
Answer: x> 2.33
None of the answer choices listed are correct.
Step-by-step explanation:
The inequality can be solved by adding 12x to both sides and then subtracting 10 from both sides:
10 - 12x + 12x < -18 + 12x
10 < -18 + 12x
Now we subtract -18 from both sides:
10 - (-18) < -18 + 12x - (-18)
28 < 12x
Finally, we divide both sides by 12:
28/12 < 12x/12
2.33 < x
So, the solution to the inequality 10 - 12x < -18 is x > 2.33.

How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.
what is the perimeter of a stained glass semi-circle if the diameter is 3 feet?
Answers
Answer:
The perimeter of the stained glass semi-circle is 3π feet.
Step-by-step explanation:
The perimeter of a semi-circle is half of the circumference of the full circle with the same diameter.
The circumference of a circle with diameter 3 feet is:
C = πd = π(3) = 3π feet
Therefore, the circumference of the full circle is 3π feet, and the circumference of the semi-circle is half of that:
C(semi-circle) = 1/2(3π) = 3/2π feet
However, the stained glass semi-circle has a curved edge, so we need to add the length of that edge to the perimeter. The curved edge of a semi-circle is half of the circumference of the full circle, or:
C(curved edge) = 1/2(2πr) = πr, where r is the radius of the circle
Since the diameter of the circle is 3 feet, the radius is half of that:
r = d/2 = 3/2 feet
So the curved edge of the stained glass semi-circle is:
C(curved edge) = π(3/2) = 3/2π feet
Adding this to the straight edge perimeter, we get:
Perimeter = C(semi-circle) + C(curved edge)
= (3/2π) + (3/2π)
= 3π feet
Therefore, the perimeter of the stained glass semi-circle is 3π feet.

Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)

https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

Answer:
a. 1/72
b. 225 ft²
Step-by-step explanation:
a.The scale is usually represented as the ratio of drawing size to actual size. Since it is generally easier to work with whole numbers, we'll use the longer dimensions of the tomato patch to find the scale:
drawing/garden = (2 in)/(12 ft) = (1 in)/(6 ft) = (1 in)/(72 in) = 1/72
Hank used a scale of 1/72.
__
b.The total length of the garden is ...
length of tomato patch + length of zucchini patch
= 1 1/2 in + 1 5/8 in = 3 1/8 in
As we saw above, each inch represent 6 ft, so the actual length of the garden is ...
(3 1/8)(6 ft) = 18 3/4 ft
The area of the garden is the product of its length and width:
A = (18 3/4 ft)(12 ft) = 225 ft²
The area of the real garden is 225 square feet.

The expression that represents how many guests the pizzas can serve is 4 x 6 ÷ 1/4.
The pizzas can serve 96 guests.
Step-by-step explanation:
For the first answer, it asks you an equation. As you can see, large parties are four times the amount of normal pizza, which is 6 pizzas, so the first part of the equation would be 4 x 6. In the second part of the problem, it states that each guest is estimated to eat 1/4 of a pizza, so you would do 4 x6 ÷ 1/4 since each guest will be eating 1/4 of a pizza at the party.
For the second part of the answers, the pizzas can serve 96 guests. All you have to do is take the equation and solve it. In this, 4 x 6 is being divided by 1/4. What you would do first is 4 x 6, which is 24, and this leaves you with 24 ÷ 1/4. As you should know, when you are dividing a number by a fraction, you flip the fraction and do multiplication instead, so in this case, it would now be 24 x 4. 24 x 4 is 96, which means that the pizzas can be served to 96 guests.

Answers
Answer:
0
Step-by-step explanation:
So,0= the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.
Hence, the values for different conditions were calculated with the help of trigonometric functions.
Part A
θ=kπ
Where k is an integer k=0,1,2..
Part B
θ=\(k\frac{\pi }{2}\)
Where k is an integer k=0,1,2..
Part C
θ=kπ
Where k is an integer k=0,1,2..
What is trigonometric function?The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths
Part A
Given that,
f(x)=2sinθ+\(\sqrt{2}\)
Non compressed length = \(\sqrt{2}\)
Then
2sinθ+\(\sqrt{2}\)=\(\sqrt{2}\)
2sinθ=0
sinθ=0
Therefore θ is the integer multiple of π
θ=kπ
Where k is an integer k=0,1,2..
Part B
Here angle is doubled
Then,
2sin2θ+\(\sqrt{2}\)=\(\sqrt{2}\)
2sin2θ=0
sin2θ=0
Here θ will be the integer multiple of \(\frac{\pi }{2}\)
θ=\(k\frac{\pi }{2}\)
Where k is an integer k=0,1,2..
Part C
g(x)=1-\(cos^{2}\)θ+\(\sqrt{2}\)
Here
f(x)=g(x)
2sinθ+\(\sqrt{2}\)=1-\(cos^{2}\)θ+\(\sqrt{2}\)
2sinθ=1-\(cos^{2}\)θ
we know that \(1-cos^{2}\)θ=\(sin^{2}\)θ
2sinθ=\(sin^{2}\)θ
sinθ=0
Therefore θ is the integer multiple of π
θ=kπ
Where k is an integer k=0,1,2..
Hence, we have solved that
Part A
θ=kπ
Where k is an integer k=0,1,2..
Part B
θ=\(k\frac{\pi }{2}\)
Where k is an integer k=0,1,2..
Part C
θ=kπ
Where k is an integer k=0,1,2..
